Complete robot without battery



In nature, the vast majority of animals use legs, regardless of whether they hop across vast plains (kangaroo), run through dense jungles (tiger) or climb rocky mountains (chamois). Although we humans utilize these same dynamics, fully understanding and reproducing this phenomenon that nature has already optimized has till now eluded us. Robots using legs have the unique attribute of enabling relatively high speed and efficiency, while allowing movement across all sorts of terrain, as opposed to wheeled vehicles which, while being extremely fast and efficient, generally require a prepared track. In the past decade, several advances in legged robotics have been made, such as the BigDog, an extremely robust quadruped able to traverse very rough terrain, or the Cornell Ranger, which holds the record for the longest walking distance of 23 Km.


Project Pegasus aims to tackle a new challenge: create an autonomous robot capable of running for 10 kilometers, thereby combining high speed with high efficiency by exploiting the dynamics of running, a gait that has so far not been implemented with great success due to the complications created by ballistic flight. The breakthroughs in this field could lead to important applications in many fields, from speedy couriers and pack-animal robots which can assist in rough environments, such as in catastrophe areas or under-developed regions, to a better understanding of bio-mechanics and improvements in prosthetics and rehabilitation robots, and even in improving the natural look of socially interactive robots.
