It is not an easy task to teach bipedal robots to keep balance while walking on any terrain. A few years ago, experts from Oregon State University (US) demonstrated their achievement in this area – a bulky robot called ATRIAS (Assume The Robot Is A Sphere). Its structure, skills, self-balancing and walking were inspired by running birds, the ostrich in particular.
The scientists had been continuously improving their scientific research, but the developers from Agility Robotics presented an improved version called Cassie two years later. The robot is deprived of the body (in the usual sense of the word), the head and manipulator hands. This solution helped to optimize its navigation on rough surfaces and improve its self-balancing.
