Big and Little Legged Robots Team Up to Conquer Terrain
Humans, robots, and anything else with legs can have issues with navigating terrain that's rough, sticky, or slippery. Navigating dangerous terrain like this isn't necessarily a problem, as long as there's a little bit of advanced warning. Imagine the difference between walking out onto an icy sidewalk that you are expecting, as opposed to walking out onto an icy sidewalk that you're not expecting.
The tricky thing is that "expecting" bit: short of actually stepping on a surface, how do you know what to expect? A robot can try relying on sensors to identify and avoid slippery terrain, but researchers from UC Berkeley and ETH Zurich came up with another effective strategy, which they presented last week at the IEEE International Conference on Robotics and Automation (ICRA).
