Project description

A Rover's Lifeline: Why Power Control Matters In a competition rover, every subsystem — wheels, robotic arm, science instruments, communication — draws power from a shared battery bus. Controlling which subsystem receives power, and when, is not just a convenience; it is a safety-critical function. A motor driver fault can stall the entire vehicle. A science module left powered during transit wastes precious battery capacity. The ability to remotely toggle and restart subsystems over the network becomes the rover's lifeline. https://docs.wiznet.io This project implements exactly that layer…
