Final answer:
The Programming Hardware Kit indeed allows ROBOTC to communicate with the robot via VEXnet Remote Control, allowing for code upload and real-time adjustments while using the remote for testing.
Step-by-step explanation:
The statement that the Programming Hardware Kit allows ROBOTC to communicate directly with the robot through the VEXnet Remote Control is true. The Programming Hardware Kit provides a way to program VEX robots using ROBOTC by establishing a connection with the robot's microcontroller. This allows programmers to upload their code and make real-time tweaks to the robot's program while using the VEXnet remote control for testing and debugging.
