The ROBOTC Development Team is excited to share our latest official update with you, ROBOTC for MINDSTORMS 4.55, which includes new features, functionality, and bug fixes. A full list of changes and improvements appear below (including an awesome sale for 3.x users), but here are the highlights:
Create Graphs from your Datalogs
Want to know what running your robot into a wall looks like to your accelerometer? Curious about how ambient light intensity varies throughout the day? Datalogging now supports (live) plotting of incoming data gathered on the robot brain. Science experiments involving sensor and motor data can be displayed. You can easily find out by gathering the data and having ROBOTC plot the data for you, as it comes in.
Datalogging is no longer restricted to just Full ROBOTC, we’ve added easy to use blocks that allow you to access the same functionality in a simple manner.
Additionally, logged data can even be exported for further analysis in a spreadsheet application of your choice.
ROBOTC Graphical Variable Support
You can now use variables in ROBOTC Graphical, as well as perform various operations on them. You can add, subtract, divide, multiple, whatever your program requires. You can use variables in loops, motor blocks, you name it!
ROBOTC Graphical Break and Continue
We’ve added two new program flow blocks, break and continue. This was a much requested feature from our more advanced users of ROBOTC Graphical. You can now create more complex programs without creating work-arounds or having to switch to ROBOTC Full.
