Unlike many underwater camera designs that must be securely held by a swimmer, 'BIKI' is a robotic fish that swims autonomously without so much as a tether.
BIKI by Robosea boasts a built-in 4K camera and the ability to dive as deep as 196 feet into the water. To control the "robofish," users may opt to use an app or a physical controller. The bot can be programmed or left to swim on its own, capturing footage all the while. If for any reason the connection is lost, BIKI knows to return to its base automatically.
BIKI, branded as the "first bionic wireless underwater fish drone," was launched as part of a project on Kickstarter that has already surpassed its initial crowdfunding goals.
