| Outline of Final Research Achievements |
In this research, in order to measure slipperiness of objects, a local slip generation mechanism using a soft elastic material was studied. By combining this mechanism with a 3-axial tactile sensor for pressure and shear forces in two directions, friction coefficient sensors that measure the friction coefficient of the contact surface in 2-axial directions were proposed. A friction coefficient sensor with fine structures of nylon tegus and that with an elastic bump were developed, and by these sensors, detection capability of friction coefficient was confirmed. As detection mechanism with nonlinear sensitivity characteristics, a cantilever structure with variable rigidity controlled by Lorentz force was evaluated. For further applications, a foot structure for robots and a tire for cars that can detect friction coefficient and slip with road surface were developed.
