Final answer:
The VEX EDR has two processors: the Cortex Microcontroller and the VEX ARM Cortex-based Microcontroller.
Step-by-step explanation:
The VEX EDR has two processors: the Cortex Microcontroller and the VEX ARM Cortex-based Microcontroller. The Cortex Microcontroller is the brain of the robot and handles tasks such as controlling motors, reading sensor inputs, and executing user-written programs. On the other hand, the VEX ARM Cortex-based Microcontroller is responsible for wireless communication and helps to extend the functionality of the robot.
