Robot parts list for Raspberry Pi rover

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.

Core parts

Raspberry Pi 5 or 4

$80

Vision, web UI and high-level logic

ESP32 motor controller

$8

Real-time motor PWM, encoders and safety heartbeat

Pi Camera Module

$30

Teleop and computer vision

4WD rover chassis

$90

Stable base with room for battery and electronics

Dual motor drivers

$25

Current-rated drivers for the chosen motors

3S Li-ion pack

$45

Main battery for drive and compute

Design variants

Vision rover

Add a Coral TPU or use lighter models for object detection.

Outdoor rover

Use larger wheels, sealed boxes and LoRa telemetry.

Practical safety note

Treat the generated output as a prototype plan, not a certified product. Body-adjacent, high-voltage, optical-energy and mobility builds need qualified review before real-world use.

FAQ

Can the Pi drive motors directly?

It should not. Use a motor driver and preferably an ESP32 or other microcontroller for motor timing.

What causes brownouts?

Undersized 5V regulators and shared motor noise.

Is ROS required?

No. ROS is useful later, but a simple web UI and serial protocol are enough for a first rover.
