| Outline of Final Research Achievements |
Regarding visual servoing using binocular visual space for humanoid robots, the method in a two-dimensional plane is extended to a method in three-dimensional space by adding the vertical direction to perform actual work, and simulations and experiments are performed. In the coordinate transformation for the control of the variable stiffness tendon drive arms with multiple degrees of freedom, we have developed a method that allows maximum movement within the motor torque limit using the redundant degrees of freedom. In order to realize a lightweight arm, we developed a force control method for mechanisms using ultrasonic motors or harmonic gears. For the purpose of application to a variable stiffness tendon drive mechanism, the effect of lowering the stiffness was clarified.
