The ROBOTC Development Team is excited to announce our latest update, ROBOTC 4.32! This update is for the LEGO MINDSTORMS (NXT and EV3) robotics systems and includes new features, functionality and a load of bug fixes.
Important Setup Information for ROBOTC 4.32:
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 (1.07X) is the same to keep alignment with the EV3 Programming Software and LEGO’s releases.
- After updating your EV3′s Linux Kernel, you’ll also need to update the ROBOTC firmware from inside of ROBOTC.
ROBOTC 4.30 —> 4.32 Change Log:
Robot Virtual Worlds Package Manager
Robot Virtual Worlds Package Manager simplifies keeping your RVW worlds up-to-date and allows you to easily download new ones.
RBC Macro Editor
The RBC Macro Editor allows you to quickly create a ROBOTC Text-Based or Graphical macro file that will pre-configure many aspects of the UI, such as platform, the debugger windows that are to be opened, the default save-as file name and many others. If you are targeting Virtual Worlds, you can also select which world should be used.
- Debug Stream has been made more robust to prevent buffer overflows and corrupted data.
- Added quick access, “Add License” menu item.
- Added command line option to deactivate all active, non-building licenses (-DEACTIVATE).
- “SensorValue” intrinsic definition changed from ‘word’ to ‘int’. This will allow it be be either ‘short’ or ‘long’ depending on the native “int” format of specific platform.
- CTRL+ALT+SHIFT+D” is new keyboard accelerator to open preferences.
- All libraries (DLLs) and executables (EXEs) are now signed.
General Bug Fixes
- Fix issue where a “save as” with a new document -> then a subsequent “save” would cause a “save as” prompt in the wrong location.
- Fix enumeration bug in Joystick Driver
- Context menu for large ICON toolbar changes now take immediate effect.
- Fix the repeatUntil(0) warning message to say “‘repeat until’ expression is constant ‘0’. Loop will never exit.”
- Fix issue with command line deactivation with building licenses
- IDE was not removing error flags from graphical blocks.
- Long operands on opcodes “&” “|”, “^” and “~” were incorrectly handling negative 16-bit constants.
- Fix bug in addTo/MinusTo/DivideTo/TimesTo opcode when variable is a global short variable and the operand is a 16-bit or less compile time constant.
- Fix issue that prevented functions that return pointers to be dereferenced in an expression.
- Fixed a bug where the missing “Name” field would cause a crash for the command line activation.
- Hitting the Control key no longer deselects all the things.
- Bug causing Graphical Block artefacts on the screen has been fixed.
- New Linux image, updated to 1.07X to ensure compatibility with LEGO EV3 Programming Software. Please be sure to update your brick to the latest Linux firmware.
- EV3 brick can now be renamed from both the file and the communication utilities in the Robot menu.
- Refreshed the Driver Suite files for both NXT and EV3
- getColorRGB() will now also work with a standard LEGO NXT Color sensor.
- Added intrinsic getSensorConnType() to retrieve sensor connection type.
- Fixed multi-tasking issue in EV3 VM where multi-tasking was not possible with programs started directly from the EV3 Brick.
- Fixed a division by zero error in DatalogTest.c sample program
- Fixed an issue where uploading a file from your EV3 to your PC removed the file extension from the uploaded file.
- LEGO NXT Sensors that are normally auto-ID’d no longer have their autoID flag disabled for that port.
- LEGO Energy Meter was improperly configured.
- Fix Standard Model issue for EV3 (Gyro was improperly configured)

We recently asked a group of engineering students from the University of Aalborg in Denmark to write about their experience using ROBOTC on a recent project. Check it out below!
Hi all! We are 6 software engineering students from the University of Aalborg in Denmark. As part of our Bachelor’s degree, we had to design and implement an embedded system, and we chose to design and implement a robot that would solve the Simultaneous Localization And Mapping (SLAM) problem. We called the robot ColumBot.
The hardware we were issued were LEGO NXT bricks and sensors as well as a few from MindSensors. MindSensors provided libraries for use with ROBOTC, which was one of the reasons why we ended up choosing ROBOTC as our IDE.
Work in Aalborg is group-based and many of the other groups spent the first weeks trying to get their NXT bricks set up for the firmwares they were using, but ROBOTC allowed us to have the part of the project kept to a minimum. ROBOTC provided us with a strong and versatile tool in solving our project, and was of great help.
Using ROBOTC, we were able to implement a mapping robot with a drive queue, with enough memory for 100m2, as well as a particle filter to correct the inaccuracies that arose from sensing when mapping. All this functionality was scheduled using a real time scheduling scheme. We do not believe this would have been possible with some of the IDEs used by the other groups.
ROBOTC has its quirks, namely much of the documentation is faulty. [Editor’s Note: ROBOTC recently went through a complete documentation overhaul to address issues like these – take a look at our help docs here.] As the focus of our project was to fit as much functionality as possible into the limited space, this problem mainly arose with the sizes of different types, where the documentation deviated from the reality. But the community is fantastic and many answers to difficult questions were found in the forums during the project period. The most useful features in our project were the Bluetooth Communication and the Debug Stream, which allowed us to monitor the robot remotely and communicate with it.
We would recommend ROBOTC to anyone attempting a build of the same size as ours, but advice you to be wary and test things for yourself, because this was sometimes a problem for us.
