ROBOTC is a powerful C-based programming language with a Windows environment for writing and debugging programs, and the only programming language at this level that offers a comprehensive, real-time debugger. ROBOTC is a cross-platform solution that allows students to learn the type of c-based programming used in advanced education and professional applications.


Benefits of using ROBOTC

  • Uses the industry standard C-programming language. Additional language extensions specifically for robotic use.
  • Modern Windows GUI with standard visual interface.
  • The only solution with fully integrated software debugger allowing users to step line by line through program execution and analysis of all variables.
  • Additional debugging tools allow the user to see the real time states of all motors and sensor. These are viewed as your program is running; not as a separate application!
  • Single solution works for both VEX Cortex and VEX PIC. No need to purchase two different applications.
  • Over 100 Sample Programs with extensive documentation so students and hobbyists can get started learning how to program
  • Advanced source code editor with smart indenting, automatic code competition and a tabbed interface to allow multiple program to be open at the same time
  • Free webinars, video tutorials, community forums, detailed help files, and curriculum provided by Carnegie Mellon’s Robotics Academy.
  • ROBOTC skills easily transitions into use of professional tools used by engineers. Not a dead end skill for VEX only!
  • ROBOTC has the same form and feel, often even the same command names, as professional tools used on other systems.
