Who has a robot collecting dust?

Flexible; to be agreed, Germany

Looking for an interesting robot that deserves another mission: educational kits, robot arms, or unusual hobby builds. Working or repairable considered. Share the model, condition, included parts, and price. Particularly interesting: programmable rover kits, compact robot arms, and educational robots with accessible software. Include battery health, charger, controller, SDK availability, and whether factory reset is possible. Missing accessories are workable if disclosed; a short power-on video is useful.
