Re: Cortex/VexNet Autonomous Mode Switching --- Newbie question
the bIfiAutonomousMode and bVexAutonomousMode variables are only needed for the older VEX PIC platform, not the VEX Cortex. When you want the robot to perform an autonomous operation in a program, just include autonomous code; when you want it to perform remote control operations, include remote control code. If your robot is synced over VEXnet, there's no extra hurdles to switch from one mode to another.
We have videos that demonstrate this in the Remote Control section of our VEX Cortex Video Trainer: http://www.education.rec.ri.cmu.edu/products/teaching_robotc_cortex/index.html
