Dustbot by Tomy.

1985, Japan.

The robot vacuum cleaner with a brain. He senses any wall or edge and turns away, won't fall of any table or desk, and really vacuum-cleans up a mess all by himself while swiveling his own broom and dust-pan.

Personal note.

This Dustbot was fully restored in 2021 with custom CAD modelled replacement tires that were 3D-printed from flexible gray rubber filament.
The 3D-models of these replacement tires can be downloaded from the Procyon Robotics Thingiverse account.
The full restoration of Dustbot can be seen in my Robot Restoration YouTube Channel.
