We all adapt our walking to the surfaces we are on without even thinking about it. Getting a robot to do it is a bit more challenging though. The PedestriANS is a bipedal robot that adapts its walking style to its environment. As the researchers Huthaifa Ahmad, Yoshihiro Nakata, Yutaka Nakamura, and Hiroshi Ishiguro explain:
By implementing an actuator network system (ANS), the robot is able to manipulate the physical characteristics of its legs and the way they interact with each other.
