Gear Up with FTC: ROBOTC Presentation

without comments

FTCFIRST TECH Challenge invited us to participate in their Summer Conference this week! Tim Friez, Senior Software Engineer, shared some advanced concepts in using ROBOTC such as understanding more about the Debugger, using 3rd Party Sensors, and coding practices to make your team more efficient and productive to develop reliable competition code. Check out the video below featuring his full presentation …

RVW FTC Block Party Competition – One Day Left!

without comments

Block Party CS2N ModeThere is only one day left to enter our Robot Virtual Worlds FTC  Block Party Programming Competitions! 

In the FTC Block Party Virtual World, program one of three robots to score as many points as possible in autonomous and driver controlled modes. Score points by:

  • Placing Blocks in Floor goals
  • Placing Blocks in Pendulum goals
  • Raising the Flag
  • Hanging from the Bar

See the rules documents for the full game explanation:

  1. FTC Block Party – Autonomous CS2N Mode
  2. FTC Block Party – Remote Control CS2N Mode

ROBOTC Graphical Natural Language

without comments

We know that text based languages (such as ROBOTC) have advantages in terms of customizability with functions, complexity with algorithms and calculations, and typically smaller sized programs over graphical languages; however, it is difficult to overcome the simplicity and ease of use that “Drop and Drag” programming languages offer to new users just getting started with programming.

TextBasedNaturalLanguage

A few years ago (with ROBOTC 3.X), we announced our “Natural Language” feature – a simplified library of commands that used “natural” commands to control your robot, such as Forward, Reverse, and LineTrackForTime. The Natural Language feature was designed to help ‘bridge the gap’ between a graphical language and the text-based ROBOTC. Teachers have praised ROBOTC’s Natural Language for making it easier to get their students up and running faster than ever before. Currently, ROBOTC supports Natural Language on the VEX Cortex, VEX IQ, and LEGO MINDSTORMS NXT platforms for both “Real” and “Virtual” robots.

GraphicalProgrammingOverview1

Today we’re proud to give you a sneak peek to a new feature we’re calling “Graphical Natural Language”. 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.

 


 

Each block is custom designed to fit the needs for that specific function and parameters. Using text boxes and drop-down menus, users can customize each values of each function to solve various challenge and activities using the same commands as ROBOTC’s Text-Based Natural Language.

FunctionsParameters
We have 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 certain number of times. With the new “Repeat” command, however, users can simply specify how many times they would like for the code to run, with no complex coding required.

RepeatCommand
Another awesome tool that we’ve implemented in ROBOTC 4.0 is the “comment out” feature. You can now comment out an entire line of code just by clicking on the block’s line number. Lines of code that are “commented out” are ignored by the robot when the program is run, which makes this feature very useful when testing or debugging a program. This new tool is unique to Graphical Natural Language.

CommentingOut
Because each Graphical Natural Language block corresponds to a real ROBOTC or Natural Language function, users will be able to graduate from Graphical Natural Language to full text-based Natural Language with the press of a single button. This will allow you 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!

NaturalLanguageWithCode
We have many other features and enhancements planned for Graphical Natural Language – Be on the lookout for a preview version sometime in January!

Please Note: The screenshots and interface in this post are not the finalized version of the ROBOTC Graphical Natural Language – the names, interface, look and feel of the system may change between now and official release.

RVW FTC Block Party Competition Now Live!

Block Party CS2N ModeCarnegie Mellon’s Robotics Academy, a research-based organization committed to teaching students how to program robots, is really excited to be able to support FTC teams again this year. Follow the links below to learn about FREE Programming Classes and a new Block Party Programming Game that can be used by students, teachers in classrooms, coaches, or competition providers. The new game is designed to teach programming and has over $5,000 in prizes. We’ve also made CS2N Groups Technology that enables teachers, coaches, and regional competition sponsors to host their own competitions.

In the FTC Block Party Virtual World, program one of three robots to score as many points as possible in autonomous and driver controlled modes. Score points by:

  • Placing Blocks in Floor goals
  • Placing Blocks in Pendulum goals
  • Raising the Flag
  • Hanging from the Bar

Setting Up Robots – LEGO Edition

without comments

SettingUpLEGONow that the physical robot kits are in the classroom and ROBOTC is installed and activated, you should be ready to build the physical robots for your classroom. One of the best features of a LEGO Mindstorms educational robotics kit is that they allow students to create a nearly limitless range of robots; the downside of this, however, is maintaining student-created robots in a classroom. To help with this, ROBOTC and their related Video Trainer Curriculum support several standard models to help keep a baseline in the classroom.

cutout_rem_gripper_T_300The first of such robots we will look at is the NXT REMbot (which stands for ‘Robotics Education Model), the standard NXT that is used in the ROBOTC Curriculum for TETRIX and LEGO MINDSTORMS. The REMbot utilizes three NXT motors (two for driving, one for the (optional) arm), a Light Sensor mounted below the robot, a Touch Sensor mounted in the front, a Sonar Sensor positioned above the robot, and a Sound Sensor on the side of the REMBot. This model allows for a variety of tasks to be completed and is designed to work with all of the challenges in the ROBOTC Curriculum.

mantis-cutout-300x275

If your classroom will be utilizing the TETRIX kit, the Mantis Robot standard model would be the build of choice. The Mantis Robot utilizes the TETRIX kit to add two TETRIX DC motors (for driving) and a TETRIX Servo (for the arm), as well as the respective motor and servo controllers; all of which are fully programmable in ROBOTC. Sensors can be added using any of the remaining sensor ports (one of which is used by the HiTechnic Motor/Servo controller chain).

Users of the MATRIX kits are not left in the dark however! MATRIX also has several options to use in the classroom, but the Quick Start Rover stands out from the pack. Combined with The Little Gripper, the MATRIX kits can be quickly and effectively set up for a standard robotics classroom. Like the TETRIX bots, the Quick Start Rover can be outfitted with NXT sensors on any of the remaining sensor ports for added versatility. It uses two MATRIX motors for movement and a MATRIX servo for The Little Gripper (all controlled through one MATRIX controller), all of which is fully programmable in ROBOTC.

Visit CMU’s Robotics Academy LEGO site for more information on the different kits available and to find build instructions.

ROBOTC Mentors – Kjersti and Violet

without comments

robotMag_2We interviewed Kjersti Chippindale and Violet Replicon, who are the mentors for the FIRST Tech Team 6002 – The Basilisks, and asked them to tell us about their FTC robotics experience. They used to be members of FTC Team Antipodes, but decided that they’d rather spend their Senior year mentoring two brand new teams in hopes to keep the robotics tradition alive at their school.
