Raspberry Pi security robot parts list

A security rover should be a mobile camera and alert platform, not a confrontation machine.

A Raspberry Pi security robot is best treated as a mobile camera, light and alert platform. It can patrol a garage, workshop or yard, but it should not confront people or use unsafe deterrents.

Focus on reliable video, night lighting, docking and remote control. Add object detection after the camera stream and alerts are stable.

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

Should it have a siren?

Use alerts carefully and follow local rules. A light and phone notification are safer defaults.

Does it need AI?

No. Motion alerts and remote viewing are enough for the first version.

Can it run outdoors?

Only with weather protection, larger wheels and conservative power design.
