OpenBot

OpenBot turns an Android smartphone into the brain of a low-cost wheeled robot. The project provides 3D-printable body variants, Arduino Nano firmware, Android apps, controller tooling and a training pipeline so a small vehicle can do person following and real-time autonomous navigation. The upstream DIY bill of materials is source-linked and described as about $50, but Motari has not reconciled a current retailer checkout total and no complete transform-bearing robot CAD assembly is available.

What you get

• A standardized, machine-readable robot schema derived from the source repo.
• A limited/simplified source 3D asset is available from body/rc_truck/cad/rc_truck_body/main_frame.stl.
• Source-backed bill-of-materials evidence is linked with per-part provenance where available. Prices marked estimated are not yet verified against a vendor.
• A transparent reproducibility score so buildability is a sortable, first-class property.
• Cross-links to the source repo, datasets, models, and forks.
