Robosea: BIKI ↗Robosea CES news ↗

Overview

BIKI was pitched as a consumer 'fish drone', a small, cordless robot fish with a fin-driven tail, a stabilized 4K camera and a claimed 55 dB noise level. Robosea (a Peking University spin-off founded in 2015) crowdfunded it on Kickstarter from May to July 2017 and was named a CES 2018 Innovation Awards Honoree for it. The scale of shipments is unclear; the Robosea site still describes 'BIKI v1.0' but lists no current US retail channel.
