True
A robot that scoops up sand, filters out litter and returns clean sand to the beach has been shown to work as described, according to materials published by Shanghai Jiao Tong University.
The machine, featured in a post on Shanghai Jiao Tong University's news site, lifts sand onto an internal sieve mechanism that separates trash such as bottle caps, cigarette butts and other debris, then deposits the sifted sand back onto the beach. Images released by the university show the robot operating on a sandy shoreline with collected waste visible in its collection area.
Beach-cleaning robots of this type are designed to reduce the manual labor involved in keeping shorelines free of litter. The university's post presents the robot as a working demonstration; no commercial availability, production schedule or performance figures were provided in the materials, and the robot's real-world deployment remains unconfirmed beyond the university's own publication.
The claim accurately reflects the device as presented: it scoops sand and selectively removes only the trash. The claim is True.
