To be useful to humans, legged robots must navigate the world much as humans do. In fall 2018, a four-legged robot named ANYmal explored the tunnels below Zurich, Switzerland in a test for what could be the future of maintenance work.
ANYmal, the creation of Switzerland-based ANYbotics and the ETH Zurich Robotic Systems Lab, resembles the BigDog family of robots, its distant North American cousins. Like the Boston Dynamics creations, ANYmal is bouncing mess of limbs that results in a sort of unsettling gait. Special actuators and gait-balancing software enable the whole production, and if need be, a limb can rotate a 360 degrees. This creates the combined effect of turning bouncy legs under the torso into long spindly legs extending outward from it.
