Opossum Cleaning Robot
WEIWEI ZHANG
Robotics, Automaton and Automation Design Opossum Cleaning Robot by WEIWEI ZHANG Opossum is a robot designed for street cleaning. The robot works at night, when streets are quiet and traffic is low. A retractable suction head, shaped like a mantis arm, extends under parked cars, so the cars do not need to be moved. Sensors and cameras guide autonomous navigation and help the robot avoid obstacles. Solar panels charge the storage batteries during the day. The main body is made of aluminium alloy and the moving parts of high-strength engineering plastics. Quiet night operation reduces noise and eases the workload of sanitation workers.
