This paper investigates the cooperative work of distributed robot maintaining retention of swarm, especially in the case of going up slope. Our control law to keep the high retention of the robot swarm has been developed, and its effectiveness for an environment with obstacles has been confirmed by using ODE (Open Dynamics Engine). This paper considers an environment with the slope and investigates...
A robust self-consistent humanoid navigation method is proposed. For any given targeted position and orientation, the robot robustly chases them without bankruptcies such as leg-crossing, excess stride and deadlock. The key idea is to define a canonical stance with respect to the target independently from the current configuration, and trace them by each step alternately. It locally prioritizes the...
In this paper, we propose a novel macro-micro tele-manipulation system based on body image embedding with contact feel, spatial motion and stereo vision for micro-manipulation under a microscope. The basic concept of body image embedding for macro-micro tele-manipulation has been already proposed by the authors. The system proposed here has three new realization ideas. The first idea is the realization...
This paper analyzes a disturbance observer with a focus on parameter variations. The parameter variations are the inertia variation and the variation of torque coefficient. Conventionally, their nominal values are designed not as control parameters but the same values as the actual ones. However, disturbance observer is able to include the effect of phase compensation by properly selecting the nominal...
A "muscle suit" that will provide muscular support for the paralyzed or those otherwise unable to move unaided is being developed as a wearable robot. Using a new link mechanism for the shoulder joint which consists of two half-circle links with four universal joints in total mounted at both ends of each link, all motion for the upper limb has been realized. New structure for easy dressing...
