A Pi rover needs a microcontroller for motors, a stable power tree and a camera stack that does not starve the CPU.

A Raspberry Pi rover is best when the Pi handles vision and networking while a microcontroller handles motors and safety. This split prevents Linux pauses from turning into runaway motion.
The power system is the make-or-break part. Use one battery pack with proper buck converters, fusing and a hard motor disable path.

Add a Coral TPU or use lighter models for object detection.
Use larger wheels, sealed boxes and LoRa telemetry.
It should not. Use a motor driver and preferably an ESP32 or other microcontroller for motor timing.
Undersized 5V regulators and shared motor noise.
No. ROS is useful later, but a simple web UI and serial protocol are enough for a first rover.
