| Research Abstract |
Aiming to implement fast walking and running, two kinds of robots, a planar one-leg jumping robot KEN-2, and a humanoid biped robot MARI-3 were developed. Stable biped walking, one-leg jumping, and two-leg jumping are implemented.
1.Planar One-Leg Jumping Robot KEN-2
Jumping can be considered as a basic element of biped running. KEN-2, a 3 DOF planar jumping robot, was developed. Its height is 800[mm] and its weight is 14.5[kg]. KEN-2 is considered as a combination of a spring and one mass point, and its detected force at the foot is controlled to be equal to that of the equivalent spring-mass model. A 4[cm] height, 100[ms] long one-leg jumping is achieved.
2.Biped Fast Walking and Running Robot MARI-3
Towards fast walking and running, a humanoid biped robot MARI-3 was developed. MARI-3 has totally 13 DOF, one DOF of waist joint in yaw axis, and 12 DOF for two legs, and each leg has 6 DOF. The height of MARI-3 is about 1216[mm] and its weight about 38[kg]. With MARI-3, a biped walking, one-leg and two-leg jumping were implemented as basic and verification experiments for fast walking and running. The validity of the robot was confirmed. The biped walking speed is 1.2[km/h]. MARI-3's one-leg jumping time (the time of MARI-3 in the air) is about 110[ms] and its jumping height is about 4[cm]. MARI-3's two-leg jumping time even reaches 150[ms]. As far as we know, that is the longest and highest jumping up to now in the world.
