In this paper, we propose a grasping mechanism for flat-shaped objects such as a dish, a plate, etc., inspired by humanpsilas lateral grasp. We analyze how the mechanism can grasp the object, and evaluate the robustness of the grasping against disturbance forces/moments applied to the grasping object. The mechanism is experimentally applied to handling of dishes, and several experimental results illustrate...
In this paper, we propose a new motion control algorithm of multiple mobile manipulators for handling a single object in cooperation with a human. In general, for handling the object, robots grasp it rigidity and a human operator applies an intentional force/moment to it. However, when the robot is operated by a human who does not have enough knowledge about robots, he/she may apply his/her intentional...
In this paper we proposed a new bilateral teleoperation based soil removing technique for demining system which is supported by geometric virtual wall concept. The virtual wall model was reflected to bilateral telemanipulation system to restrict a motion of the slave manipulator beyond the geometrical virtual wall. The algorithm was experimentally applied to a bilateral telemanipulation system. The...
This article introduces several types of robots having physical interactions among a human/humans and a robot/robots, which we have developed so far. MR Helper (mobile robot helper) is a mobile robot with dual manipulators, which could manipulate an object in cooperation with a human. DR Helpers (distributed robot helpers) are multiple small mobile robots which transport an object in cooperation with...
