Jellyfishbot

A compact electric harbour robot that trawls floating waste and oil into towed nets — remote-controlled or fully autonomous, covering about 1,000 m² an hour in marinas and industrial ports.

At 70 × 70 × 48 cm and 20 kg it is built for tight corners bigger craft can't reach, with three multidirectional thrusters, GNSS positioning and obstacle avoidance above and below the surface. Swappable batteries give 6–8 hours per charge, and with sonar and probe accessories it also maps harbour floors (bathymetry to 10–20 m) and measures water quality.
