  • Users will also have to update their VEX IQ Wireless Controller in addition to any other VEX IQ Devices (sensors, motors) that may need to be updated as well.
  • After updating to the latest VEX IQ Brain firmware, users will also have to install the latest ROBOTC firmware from inside of ROBOTC.

VEX Cortex Users (with Black VEXnet 1.0 Keys):

  • You will need to update your VEX Cortex and VEX Game Controllers with Master Firmware Version 4.23 from inside of ROBOTC.
  • After updating the master firmware, users will also have to update the VEX Cortex with the latest ROBOTC firmware as well.

VEX Cortex Users (with White VEXnet 2.0 Keys):

  • The new VEXnet 2.0 keys have a specific “radio firmware” that you will need to upgrade to enable “Download and Debugging” support. You can download the VEXnet Key 2.0 Firmware Upgrade Utility here.
  • Download the “VEXnet Key 2.0 Firmware Upgrade Utility” and insert your VEXnet 2.0 key to any free USB port on your computer. Follow the instructions on the utility to update each key individually. All VEXnet 2.0 keys must be running the same version in order to function properly.
  • After updating your VEXnet 2.0 keys, you will need to update your VEX Cortex and VEX Game Controllers with Master Firmware Version 4.23 from inside of ROBOTC.
  • After updating the master firmware, users will also have to update the VEX Cortex with the latest ROBOTC firmware as well.

LEGO NXT Users:

  • Simply update to the latest ROBOTC firmware from inside of ROBOTC.

LEGO EV3 Users:

  • All users will need to update the  LEGO EV3′s Kernel by connecting the EV3 and selecting “Robot Menu -> Download EV3 Linux Kernel” from inside of ROBOTC. The version number is the same to keep alignment with the EV3 Programming Software and LEGO’s releases, but the Kernel has bug fixes to increase sensor reliability.
  • After updating your EV3′S Linux Kernel, you’ll also need to update the ROBOTC firmware from inside of ROBOTC.

ROBOTC 4.26 -> 4.27 Change Log:

  • Support for the EV3 platform in Robot Virtual Worlds.
  • Updated NXT 3rd Party Sensor Library with latest release from BotBench.com
  • Update Built In Variable files for missing EV3 compatible commands.
  • Added EV3 motor synchronization functions: setMotorSyncEncoder and setMotorSyncTime.
  • Add “Autobot IQ” as a standard model for VEX IQ platform.
  • Fixed an issue where bad parameters to “Read Data from Flash Memory” message may cause problems for EV3 downloading.
  • Fixed NXT Joystick issue – update to JoystickDriver.c to start the “readMsgFromPC” task upon first request for joystick data (prevents Natural Language from keeping the task from starting).
  • Set the “Project Explorer” window to be hidden by default.
  • Added 200ms sleep to EV3 prolog code after sensors have been reset and configured. Ensures first reads from sensors in user programs contain useful data.
  • Updated “Official” kernel image for EV3 to remove debugging noise on sensor port #1 – Version number is still 1.06X, but requires users to update the EV3 Kernel.
  • Task queue was not being initialized for EV3 firmware except when running with Debugger. Caused all multitasking programs started from the On-Brick EV3 GUI to fail.
  • Adjust NL Libraries for Forward/Backward issues on NXT platform.
  • Adjust EV3 Motor Commands (moveMotorTarget, setMotorTarget) to use a better ramping algorithm – movements are now a lot more reliable.
  • Updated licensing system to fix potential encryption vulnerabilities.
  • Fix a bug where an incomplete TETRIX configuration line will cause ROBOTC to crash.
  • Added a super user toggle to silence the “Must set Team Number” value for Cortex Competition Mode.
  • Fixed issue where Debugger Windows (Motors, Sensors, Variables) were not appearing after subsequent downloads/debugging sessions.
  • Fixed issue with EV3 touch sensor and EV3 bumped sensor values (and resetting those values) in EV3 Firmware.
  • Updated Swervebot “standard model” to include VEX Motor IMEs
  • Fix an issue with “Save As” always pointing to the “My documents” folder – this forced redirect should only take place for saving NEW files.
  • Modify Natural Language main include to be a “warning” instead of error when using emulator mode.
  • Added new RBC Macro Command to switch “External Controllers” flag.
  • Fix encoder issue with emulator platforms (mix between raw encoder counts and “scaled”)
  • Fixed a bug where the joystick station would not appear / crash ROBOTC when using IQ or Cortex platforms.
  • Fixed accidental bug where motorPWM was disabled for the NXT platform.
  • Fixed a bug where Virtual Worlds/Emulator VEX IQ was not displaying the correct values in the debugger for the specific color sensor mode.
  • Remove some unneeded color enums from EV3 native bytecodes libraries.
  • Improved support for use of “enum” and “struct” keywords. Previously declarations were of the format ” “; now they can also be of form “struct “. Similarly for “enum” keyword. ROBOTC compiler is a blend of C and C++ syntax for “enum” and “struct” recognition.
  • Fix “Include” file issues (i.e. forward slash vs back slash + relative path issues)
  • Add special “Start Page” if users have a PLTW license.
  • Functions whose return value is “void *” were incorrectly generating a ROBOTC compiler error.
  • Added VEX Cortex 4.23 Firmware Images
  • Added support for VEX IQ 1.13 Firmware
  • Enhancements to Virtual Worlds Joystick Control with Natural Language/Graphical
  • Updated values the Joystick Debuggers display when buttons are pressed.

_____________________________________________________________________________

Before you can use ROBOTC 4.25, you will need to ensure that your devices are up to date. The instructions to update your hardware will be different depending on what hardware setup you may have…

LEGO NXT Users

  • Simply update to the latest ROBOTC firmware from inside of ROBOTC.

LEGO EV3 Users

  • Update your LEGO EV3′s Firmware/Kernel by connecting your EV3 and select “Download EV3 Linux Kernel” from inside of ROBOTC – This process will take about 5 minutes and will allow your EV3 to communicate with both ROBOTC and the EV3 Icon-Based programming language. After updating your EV3′S Linux Kernel, you’ll be able to install the ROBOTC firmware from inside of ROBOTC.

VEX IQ Users

  • Run the “VEX IQ Firmware Update Utility” and update your VEX IQ Brain to firmware version 1.10. You will also need to update your VEX IQ Wireless Controller by attaching it to your VEX IQ Brain using the tether cable. You will also have to install the latest ROBOTC firmware from inside of ROBOTC.

VEX Cortex Users (with Black VEXnet 1.0 Keys)

  • You will need to update your VEX Cortex and VEX Game Controllers with version 4.25 from inside of ROBOTC. After updating your master firmware, you will also have to install the latest ROBOTC firmware as well.

VEX Cortex Users (with White VEXnet 2.0 Keys)

  • The new VEXnet 2.0 keys have a specific “radio firmware” that you will need to upgrade to enable “Download and Debugging” support. You can find the “VEXnet Key 2.0 Firmware Upgrade Utility” utility here.
  • Link: http://www.vexrobotics.com/wiki/index.php/Software_Downloads
  • Download the “VEXnet Key 2.0 Firmware Upgrade Utility” and insert your VEXnet 2.0 key to any free USB port on your computer. Follow the instructions on the utility to update each key individually. All VEXnet 2.0 keys must be running the same version in order to function properly.
  • After updating your VEXnet 2.0 keys, you will need to update your VEX Cortex and VEX Game Controllers with version 4.25 from inside of ROBOTC. After updating your master firmware, you will also have to install the latest ROBOTC firmware as well.

_____________________________________________________________________________

And finally, the very LONG Change Log for 4.25:

  • Cortex: Added servo motor commands to Cortex for Virtual Worlds.
  • Cortex: Added potentiometer commands to Cortex for Virtual Worlds.
  • Cortex: Add Timers and Clear Timers to Graphical for Cortex.
  • IDE: Spurious “rbg” file extension may have been added when saving a text file created from converting a graphics file. Fixed.
  • EV3: Update the routine that checks for “valid syntax of NXT on-brick file” for EV3. EV3 has different rules for file names than NXT.
  • VEX IQ: Added sound commands to Natural Language for VEX IQ – modified the playNote command to use typedefs to make it easier for natural language users.
  • Compiler: When substituting symbol names that match except with different letter case do a better job of handling the case when multiple symbols might possibly fit.
  • EV3: Support for standard ROBOTC “playTone” file with EV3.
  • Updated IDE Version (4.25)
  • Updated Firmware Version (10.25)
  • IDE: New Help System Engine + Content Files (replaces CHM)
  • Debugger: Fixed issue where VEX IQ motor debugger window was displaying “raw” encoder counts instead of “scaled” encoder counts.
  • Virtual Worlds: Adjust “no echo” value for VEX IQ in Emulator/Virtual Worlds
  • IDE: Default directory has been adjusted to be “my documents” instead of the root ROBOTC directory for saving un-saved files.
  • Compiler: Format code “%f” was broken in implementation when a number of decimal specifier wasn’t provided. Fixed.
  • Natural Language: Updated Natural Language Libraries to include “debugging” to LCD commands.
  • GUI: Updated Desktop/Start Icons for Graphical
  • Debugger: Sensor window had some “artifacts” when the number of display rows was larger than the number of active sensors. Fixed so that artifacts are now blank lines.
  • Compiler: Fixed compiler bug. Conversion of ‘float’ constant expressions to ‘long’ constant value was incorrect. End result of bug was that most likely value assigned was zero.
  • EV3: Added resources to the firmware image with sounds and images in /home/root/lms2012/resources/
  • EV3: EV3 firmware from LEGO does not properly handle the use of ‘.’ in the middle of filenames. Replace the ‘.’ with ‘_’.
  • Compiler: Fixed issue with rand() – Compiler was incorrectly optimizing get/set property opcodes to a one-byte index value with constant parameters. Almost all properties only need one byte with exception of “propertyRandom” which was behaving incorrectly as a result of this bug.
  • Graphical: Support for “compiler error” display for graphical files including using “graphical block numbers” rather than “text line index” for error display.
  • Graphical: Tweaked graphical loop block colors.
  • VEX IQ: Allow the debugger to display information based on the global motor encoder units instead of raw counts for VEX IQ
  • Cortex: Updated VEX Cortex IME Support to reflect new motor type (393 with Turbo Gears). Also removed some inconsistencies in the software as well.
  • EV3: When USB connected EV3 is disconnected then ROBOTC would not reconnect to it when reconnected until ROBOTC application was existed and re-entered. The problem was ROBOTC was using a “old” list of “discovered devices”. Now discards list of devices and rescans — when connecting via USB only — and problem is resolved.
  • EV3: Support for EV3 text drawing to screen.
  • EV3: Breakpoints now working for EV3.
  • EV3: Add support for “EV3 Remote Screen” as part of the Debugger.
  • Compiler: Improved implementation of compiler parse for ‘typedef enum” and “typedef struct”. Implementation is now closer to standard “C” with better handling for “anonymous” typedefs. Does not break any sample programs.
  • IDE: “Open Include File” command in source file context menu was broken; fixed. “Go to symbol definition” context menu command now filters out macro parameters and procedure variables.
  • NXT: Fixed issue where “simple” game controller data wasn’t appearing in available debugger windows
  • Graphical: Graphic trash can implementation. You can drag selection to the trash can to delete blocks.
  • NXT/EV3: Fix spurious generation of “#pragma config” for PID settings that are all set to 0xFF values.
  • Graphical: Syntax checking on graphical files. Some errors are now flagged.
  • Graphical: Implement “Comment” block for Graphical views including edit capability.
  • EV3: New Commands for EV3 IR Sensor
  • EV3: New Commands for EV3 Bumper/Touch Sensor
  • EV3: New Commands for EV3 Color sensor
  • EV3: New Commands for EV3 Gyro sensor
  • EV3: New Commands for EV3 Touch Sensor
  • Graphical: “>” and “<” comparison operators were swapping when saving a graphical file. Fixed.
  • IDE: When a new source file is opened (or a template file) do not initially set the “modified” flag in the file. Only set the modified flag after end user has modified the file.
  • IDE: Avoid double “Save File” prompt when compiling a file and on the first SAVE prompt you click cancel.
  • EV3 Kernel: Image of latest build – version 1.06X and all the I2C enhancements.
  • EV3: IDE “File Management” window for EV3 was often crashing; fixed a buffer read overflow situation which clears this up. Better text error message when there is not enough free flash memory to write a new file to the EV3.
  • IDE: Disable “error” message box when pulling USB cable from robot brain (and the debugger shuts down).
  • VEX IQ: Visual Error handling for Debugger Exceptions (Wrong Motor/Sensors/etc)
  • VEX IQ: Updated GUI Text: When a ROBOTC AUTO program had previously ran, and then a user was trying to access a TeleOp program, they would be greeted with a “No Radio Needed…” message box. Updated the text to reflect that if they’re seeing a message they probably need a remote control, because this string is never presented to the user for more than a split second in Auto mode.
  • IDE: Fixed issue with “Sensors” debugger window not being able to be edited.
  • VEX IQ: fixed Issue with VEX IQ Color Sensor – Hue values were being scaled improperly.
  • Graphical: Reduce flicker on graphical view when dragging blocks.
  • Graphical: Added registry options to adjust the appearance of graphical programs. Includes show/hide {}. Show/hide semi-colons. Optional “end” text on end block. Etc.
  • Robot Virtual Worlds / VEX IQ: Invert the proximity value provided by the vex color sensor to align with real hardware.
  • IDE: Add support to “Motors and Sensors Setup” to store drive side — left/right/none — for each motor. Graphical Movement Commands will now use this data to decide what motors to drive
  • Graphical: Adjust width of graphic programming blocks based on contents of edit controls and width of drop down menu items.
  • Graphical: Added EV3, VEX Cortex and NXT as “Graphical Language” platforms.
  • Bug: Large ICON toolbar was not getting built when IDE is opened unless it was “opening last file”. Changed data table to ensure that it is initially built.
  • IDE: Added ability for “Macro” commands to Compile/Download/Launch Graphical Files when special flags are stored inside of the .RGB files.
  • Graphical: VEX IQ Motors and Sensors now support dynamic menus based on Motors and Sensor Setup Data

Announcing VEX Skyrise Robot Virtual World!

without comments

The ROBOTC and Robot Virtual World team are thrilled to announce their latest virtual world: VEX Skyrise! The VEX Skyrise virtual world simulates the brand new VEX Robotics Competition, announced today at VEX Worlds, for the 2014-2015 season. Like previous simulations of the competitions, this virtual world includes multiple fully programmable robots, the correctly scaled field and game objects, and score and timer tracking. It’s absolutely perfect for teams who want to do strategic planning and learn how to program. Check out video of the new game here!

VEX Skyrise

VEX Skyrise features very high scoring goals this year. To account for this, we’ve added a brand new robot: RVW VEX Scissorbot. Scissorbot can pick the cube game objects off of the ground and quickly score them in the highest goals. It is fully programmable with motors, encoders, a gyro sensor, sonar sensor, potentiometer, and line tracking sensors.

Scizzorbot

We’ve also adapted our RVW VEX Scooperbot model with a gripper and linear slides, allowing it to grab game objects from the floor, extend its arms, and drop them onto the goals. We’ve dubbed this version RVW VEX Fantasticbot. It also features a full set of motors and sensors, making it fully programmable.

Clawbot

The download for the VEX Skyrise virtual world, along with additional helpful information can be found at RobotVirtualWorlds.com. To help you get started, sample code is included with the world, but also can be downloaded here:  RVW VEX Skyrise Sample Code

Good luck to all of the VEX teams at Worlds during the final day of the competition. We look forward to another great season!

Update – ROBOTC for VEX Robotics 4.08

with 4 comments

ROBOTC logo 4 UpdateThe ROBOTC Development Team is excited to announce the availability of ROBOTC for VEX Robotics 4.08 – an update for the VEX Cortex and VEX IQ platforms. This new version supports the latest firmware versions provided by VEX Robotics (4.20 for VEX Cortex / 1.09 for VEX IQ) and all of the new features supported by the new firmware updates. Some of these new improvements include:

- Support for the VEXnet 2.0 (white) Radios for the VEX Cortex
- Bug Fixes for the VEX IQ system to prevent “I2C Errors”
- Speed enhancements for VEX IQ for better performance of motors and sensor
- New VEX IQ commands for Gyro sensors

This new version of ROBOTC also supports the VEX IQ “Graphical Natural Language” feature. This new interface allows users to program robots from inside ROBOTC with easy-to-use graphical blocks that can be drag-and-dropped to form a program. Each block represents an individual command from the “text-based” ROBOTC and Natural Language. The new click and drag interface along with the simplified commands of Natural Language allows any robotics user to get up and running with programming their robots as soon as possible. As of today, the Graphical Natural Language commands work with the VEX IQ system, but we’re actively developing support for ALL ROBOTC supported platforms!

Before you can use ROBOTC for VEX Robotics 4.08, you will need to ensure that your VEX devices are up to date. The instructions to update your hardware will be different depending on what hardware setup you may have…

  • VEX IQ Users
    • Run the “VEX IQ Firmware Update Utility” and update your VEX IQ brain to firmware version 1.09. You will also have to install the latest ROBOTC firmware from inside of ROBOTC.
  • VEX Cortex Users (with Black VEXnet 1.0 Keys)
    • You will need to update your VEX Cortex and VEX Game Controllers with version 4.20 from inside of ROBOTC. After updating your master firmware, you will also have to install the latest ROBOTC firmware as well.
  • VEX Cortex Users (with White VEXnet 2.0 Keys)
    • The new VEXnet 2.0 keys have a specific “radio firmware” that you will need to upgrade to enable “Download and Debugging” support. You can find this utility here.
    • Download the “VEXnet Key 2.0 Firmware Upgrade Utility” and insert your VEXnet 2.0 key to any free USB port on your computer. Follow the instructions on the utility to update each key individually. All VEXnet 2.0 keys must be running the same version in order to function properly.
    • After updating your VEXnet 2.0 keys, you will need to update your VEX Cortex and VEX Game Controllers with version 4.20 from inside of ROBOTC. After updating your master firmware, you will also have to install the latest ROBOTC firmware as well.
    • Note that this new firmware version will support download and debugging with both VEXnet 1.0 (black) and VEXnet 2.0 (white) keys.

Here’s the list of changes and enhancements between version 4.06 and 4.08.

VEX Cortex:

  • Support for VEX Cortex Master Firmware 4.20 and VEX Game Controller Master Firmware 4.20
  • Support for wirelessly download and debugging using the new VEXnet 2.0 2.4Ghz radios.
  • Fixed an issue with launching ROBOTC in “Virtual Worlds” mode, which may incorrectly choose the wrong compiler target.
  • Fixed issue with Windows XP/Vista/8 where ROBOTC may crash when unplugging/plugging in a device

VEX IQ:

  • Improved motor responsiveness (16ms update cycles as opposed to 50ms today – this was a mitigation for the I2C issues in the current Master FW)
  • Improved sensor responsiveness (varies by sensor – this was a mitigation for the I2C issues in the current Master FW)
  • Gyro sensors can now return either integer values (getGyroDegrees/getGyroRate) or floating point values (getGyroDegreesFloat/getGyroRateFloat)
  • Fixed a bug where the Gyro sensor was not using the “rate” setting to properly return a deg/sec calculation for the getGyroRate command.
  • Exposed the ability to calibrate the gyro sensor from the user program and specify the number of “samples” to take during calibration (more samples = less drift = longer calibration time)
  • Also added a boolean “get” command to read the gyro calibration status bit to know when calibration is done.
  • New PWM adjustment function – allows users to trigger a specific VEX IQ motor to read the current battery voltage from the VEX IQ brain to adjust the PWM scale factor in the motor to ensure consistent performance. This is automatically done each time a program is executed with ROBOTC, but for longer programs end-users might want to readjust the PWM scale factor.
  • New “read immediate current” from motor – returns a value in mA
  • Modified functions for “motor strength” – renamed these to be “motor current limit” and uses values in mA instead of 0-255 byte value. These commands used to be called “getMotorStrength” and “setMotorStrength” – they’re now renamed to “getMotorCurrentLimit” and “setMotorCurrentLimit”
  • Fixed an issue with “Graphical” mode where users may start up in “Cortex” mode and the function library will appear blank
  • Fixed an issue when “Natural Language” mode was enabled that normal sample programs may not run properly (using the leftMotor/rightMotor keywords)
  • Fixed issue with Windows XP/Vista/8 where ROBOTC may crash when unplugging/plugging in a device

If you have any questions or issues, contact us at support@robotc.net. Happy Programming!!

ROBOTC Graphical Programming Preview Available!

without comments

clickanddragAfter months of work, the ROBOTC Development Team is excited to announce the availability of the first preview release of ROBOTC Graphical Language for the VEX IQ platform. This new interface will allow you to program robots from inside ROBOTC with easy-to-use graphical blocks that can be drag-and-dropped to form a program. Each block represents an individual command from the “text-based” ROBOTC and Natural Language. The new click and drag interface along with the simplified commands of Natural Language will allow any robotics user to get up and running with programming their robots as soon as possible.

The first release of ROBOTC Graphical Language is available for the VEX IQ platform for use with the standard VEX IQ Clawbot and Autopilot Robots. All ROBOTC 4.0 users will receive access to the new Graphical Language interface at no additional cost! Our plans over the next few months are to extend the Graphical Language interface to all of ROBOTC’s support platforms, including the Robot Virtual Worlds technology. You can download the preview version today at http://www.robotc.net/graphical/.

———————————————————————————————————————————————————-

The new ROBOTC Graphical programming environment adds a number of new features we’d like to highlight:

Graphical Language Command List (Drag and Drop)

GraphicalFunctionBar
With the new ROBOTC Graphical Mode, we’ve updated our “Functions Library” to match the style of the Graphical interface. This new mode will allow you to drag and drop blocks of code from the “Graphical Functions” menu into your program to get your program created even faster!

New Language Commands for Easier Programs

NewLanguageCommands
We also added some new language extensions to both ROBOTC and Natural Language; such as the simplistic “Repeat” command. Prior to the Repeat command, users would need to copy and paste large sections of code or use a looping structure (like a ‘for’ or ‘while’ loop) in order to have a set of actions repeat a number of times. With the new “Repeat” command, however, users can simply specify how many times they would like the code to run, with no complex coding required. And users who wish to make an “infinite loop” can use the “repeat forever” command to accomplish this task quickly!

Commenting Blocks of Code!

CommentingOut
Another awesome tool that we’ve implemented in ROBOTC Graphical is the “comment out” feature. You can now comment out an entire line of code just by clicking on the block’s line number. The robot ignores lines of code that are “commented out” when the program runs, which makes this feature very useful when testing or debugging code. This new tool is unique to ROBOTC’s Graphical interface.

Updated and Simplified Toolbar

Toolbar
Sometimes navigating menus as a new user can be a little overwhelming – so many options to choose from and lots of questions about what each option is used for. To help with this, we’ve redesigned ROBOTC’s toolbar to make getting up and running easier. We put the most used commands on a larger toolbar so new users have an area to easily click to download firmware, send their code to their robot, and run their programs without having to use the standard menu interface.

Convert to Text-Based Natural Language

ConvertToText ConvertToText2
Because each Graphical Natural Language block corresponds to a real ROBOTC or Natural Language function, users will be able to graduate from Graphical Programming to full text-based programming with the press of a single button. This allows users to naturally transition from Graphical Natural Language to the text based Natural Language (or ROBOTC), without having to worry about manually converting the code line-by-line!

Teacher’s Guide and Sample Programs

UsersGuide
The new graphical interface includes over 50 new sample programs to help you get up and running with working examples and demo code. In addition, we’ve also developed a 30+page guide to walk new (and existing) users through the new Graphical Programming interface and getting started with the VEX IQ platform. You can find a link to the programming guide here and also on the ROBOTC Graphical page.

Updates to Ruins of Atlantis and Operation Reset

with one comment

We’re happy to announce that we have a fresh batch of Robot Virtual Worlds updates for you! Read on for more detail.

Ruins of Atlantis

  • We’ve added lots of really cool ocean life to the level, over 20 species of fish. See if you can spot them all! These and other visual elements can be disabled in the Options menu of the splash screen.
  • Badges for completing the Ruins of Atlantis path with each robot have been added (See below). Each of the three robots available has different dimensions, so this rewards the student for completing additional math and programming practice.
  • We’ve updated our high resolution printable map with valuable information and fun, themed elements.
  • A comprehensive teacher’s guide is now included, which covers everything from getting started, programming options available, and how to teach with the tools in the world.

Operation Reset

  • Operation Reset has been updated to include the latest physics engine.
  • A number of small bugs have been resolved. Thanks for the feedback!

  • Even more sample programs to help users get started, including samples for new platforms and advanced programming concepts!
  • Support for both VEX Cortex and VEX IQ in ROBOTC for VEX Robotics 4.0
  • Support for both NXT and EV3 in ROBOTC for LEGO MINDSTORMS 4.0
  • No-Cost standalone version of ROBOTC for VEX PIC for legacy users.

Pricing and final availability for 4.0 has not been finalized; however customers can feel secure buying ROBOTC today knowing they will get a full ROBOTC 4.0 upgrade as soon as it is available.

Current ROBOTC Users Upgrade Details:

Robot Virtual Worlds Measurement Toolkit

without comments

Measurement-Tool-KitWe recently added a great new feature to our Robot Virtual Worlds … the Measurement Toolkit! There is no more guessing on how far a robot needs to travel to solve programming problems. It allows for intelligent path planning and navigation. You can now have students do the math, show their work, and explain how they solved the problems.

Check out our newest video that talks about what the measurement toolkit can do in RVW!
