Abstract
Robots are not mere applications of existing theories, but can be huristic tools to find out various new ideas. This paper proposes “huristic bio-robotics” to get new scientific findings by using robots and applys the idea for approaching to adaptive bipedal walking. We have developed a series of biped robots to realize adaptive locomotion. Experimentally realized walking cannot be extrapolated by the existing theories on bipedal walking robots and can contribute to the biomechanics to understand the physical meaning of the biological body.
