The ROBOTC Development Team is very excited to announce our latest release update, ROBOTC 4.27! This update is for the both the VEX Robotics (CORTEX and IQ) and LEGO MINDSTORMS (NXT and EV3) robotics systems and includes new features, functionality and a load of bug fixes! Download the latest update and take a look at the setup information below.
Important Setup Information for ROBOTC 4.27:
VEX IQ Users:
- Run the “VEX IQ Firmware Update Utility” and update your VEX IQ Brain to firmware version 1.13 (may not be available at time of release, but will be available soon).
- 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.
- Increased height of the Joystick Station Debugger Windows to allow multiple buttons descriptive text

We are at the 2014 PLTW Summit in Indianapolis this week! Stop by our booth to say hi and ask us questions.
We also have our latest iPad app, Robot Virtual Worlds Expedition Atlantis, available to try out.
And there is a ROBOTC Maze Challenge where you can program a VEX IQ robot using ROBOTC Graphical.
We look forward to seeing everyone!
Expedition Atlantis immerses you in a world of underwater robotics exploration, where you must solve math problems to control your robot’s movement in the deep seas ruins.
The math problems will help students understand proportional relationships and the basics of robot programming. It is designed for the student to learn as they play, and includes in-game tutorials to help them play along. As you play, you’ll be able to customize your robot, and also earn achievements through our Computer Science Student Network (CS2N). A full teacher’s guide for using Expedition Atlantis in the classroom is available at www.robotvirtualworlds.com/ipad.
Expedition Atlantis was tested in a number of diverse classroom settings. In every case, students had measurable gains in proportional understanding, as well as increased interest in math and robotics. Read more about the research here!

Xander over at BotBench shared a really cool video a couple weeks ago when he attached a GoPro to his VEX IQ that was programmed in ROBOTC. He didn’t get any pictures of the robot with the camera on it, but you can see where it was held by the rubber bands on the end of the boom in the pictures below. The angle of the boom was also remote controllable.
And check out the video here …

Check out this sneak peek of ROBOTC Lite running on the iPad! You can
use the new ROBOTC Graphical commands to control virtual VEX IQ and
fantasy robots. Be on the lookout for a free beta version on the iTunes
App Store coming soon.
If you haven’t had the opportunity to try out our new Graphical Interface yet, watch our new video to find out what you’re missing! The new ROBOTC Graphical 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.
The Mohave Robotics team (7681B) shared with us that their team voted to kick off their VEX IQ season using ROBOTC Graphical instead of the regular version they used last year. Per their teacher, Bert te Velde, “We wanted to get more people involved with programming and ROBOTC Graphical was the logical step to allow everyone on the team to get involved, no matter what their prior level of experience.”
In November 2013, Mohave Middle School sent four 7th graders to Scottsdale Community College for a three month course in full ROBOTC. The results were worth the effort, with Mohave winning the VEX IQ Programming Award at the VEX IQ Arizona State Championship in March 2014, and placing 14th at the VEX IQ World Championship in April 2014. “And they did that with a modified clawbot, one ball at a time!” exclaims Glenn Clevenger, one of the team’s mentors. “It’s hard to believe that they went from scoring 1 point at their first qualifying event in January to scoring 40 points at the VEX IQ World Championship in April. These kids are proof that ROBOTC is not too difficult for a 7th grader to handle.”
If you are wondering why Mohave is moving to ROBOTC Graphical, it’s because they plan to have their 8th graders teach all of the 6th and 7th graders that participate in VEX IQ how to program this year. The 8th graders decided it would be faster to get the new team members up to speed on the graphical version, without having to worry about syntax errors. And they can always convert their program to full ROBOTC if they need to later into the season.
Cameron Akker is the 2014 REC Foundation-RoboMatter scholarship recipient and will receive $5,000 intended for students pursuing a degree related to science, technology, engineering or mathematics. Cameron attended Redmond High School and is a member of VEX Team 575, Exothermic Robotics of Redmond, Washington. He will attend Harvard University this fall. Cameron, on far right, is pictured here with his Exothermic Robotics teammates.
Cameron started programming for the first time in 9th grade and pursued a variety of summer programs to improve his skills. He began by learning ROBOTC, picked up Java at a Stanford University program, and took a course focused on robotics programming using language C at the University of Pennsylvania. Last summer, Cameron put his knowledge to use and got together with friends he met through robotics to start a mobile app company. Working straight through the summer, the group was able to create and release two Android games on Google Play.
When it comes to programming robots Cameron says, “Virtual worlds is an excellent interface through which I’ve been able to program without the rough, troublesome physicality of actual robots. It’s helpful to be able to test programs without the possibility of one mistake leading to a physical robot’s untimely demise. The Carnegie Mellon Robotics Academy sponsored Robot Virtual Worlds Competition provides an exciting chance to experience the thrill of robotics programming without needing to attend a physical robotics competition.”
“Understanding programming has also aided the way I build robots to participate in the VEX Robotics Competition,” continues Cameron. “Instead of building an entire robot and then programming it, I program the robot at every step of the build process. As a result, I don’t have to wait until the end of the build process to find broken motors or faulty engineering, but can rather find them along the way. Understanding programming has also allowed me to better set up sensors on a competition robot. Instead of putting sensors on the robot and later figuring out how to incorporate them, I only add sensors when there is a clear need in programming for them.”
The REC Foundation and RoboMatter congratulate Cameron Akker on his well-deserved scholarship award and wish him much success in his college career at Harvard University.
