Which version of RobotC?

Hello. I am a complete and absolute noob when it comes to robots, but I want to learn everything I can.

I recently assembled my VEX clawbot, and now I want to program it. I am following the video trainer series but am confused.

What I want to do is to update the firmware and start programming wirelessly, but to do that, do I need ROBOTC for VEX 4x or ROBOTC for Cortex and PIC?

This may be a dumb question. Oh well.


Assuming you have a cortex controller with your clawbot.
cortex controller

you should purchase ROBOTC V4.xx for programming (there is a 10 day trial you can use to try it out).
