Back in 2013, we heard about an all-terrain walking robot known as RHex. Designed in a collaboration between McGill University and the University of Pennsylvania, it used six flipper-like legs to scamper around. Now, its successor is taking to the briny depths.
Called the Aqua2, the new robot is soon to be commercially manufactured by McGill spinoff company Independent Robotics.
It builds upon a previously-developed one-off aquatic version of Rhex, moving both across land and underwater. The robot has been tested to a depth of 36.5 m (120 ft), where it can operate either autonomously or by optical-tethered remote control.
