A robot vacuum is a navigation project wrapped around a dust-collection problem.

A robot vacuum is a navigation project wrapped around a dust-collection problem. The first prototype should prove that it can move under furniture, avoid stairs, survive bumps and collect visible debris in a controlled room.

Skip full home mapping at first.

Skip full home mapping at first. Random bounce or simple wall-follow coverage is enough to test mechanics. Add mapping only after the bumper, cliff sensors, fan airflow and battery runtime are reliable.

Design variants

Single-room prototype

Bounce navigation, bumper safety and manual charging.

Wall-follow cleaner

Add side distance sensing to cover edges more consistently.

Mapping upgrade

Add 2D LiDAR or camera mapping only after cleaning hardware works.

FAQ

Can I make one cheaper than buying one?

Usually not if you only want cleaning. The DIY value is learning navigation, sensing and airflow.

What sensor matters most?

Bumper and cliff sensors. They prevent the most common failures.

Does it need LiDAR?

No for a first cleaner. Coverage and safety can be tested without mapping.
