Autonomous travel-type cleaner

This is a robotic cleaner that automatically detects corners. Once a corner is found, it performs a back-and-forth, swinging motion to clean that specific area until no more dirt is detected. The patent specifically describes this swinging motion as being controlled by individual motors for its left and right wheels.

Why it matters: Since 2015, the cost and accuracy of environmental sensors and embedded processors have significantly improved. This makes the precise corner and rubbish detection, along with the responsive control needed for the reciprocating motion, much more feasible and efficient to implement today.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateControl unit, sensors, motors, software logic.
