We introduce a passive mobile robot called CPRP (Caster-type Passive Robot Porter). This robot consists of multiple casters with servo brakes and a controller. C-PRP employs passive dynamics with respect to the force applied by a human. Its appropriate motion is controlled using the servo brakes. In this paper, we derive and analyze a feasible braking force/moment that can be applied to the robot...
In this paper, we introduce a passive mobile robot called PRP (Passive Robot Porter), which has passive dynamics with respect to an applied force and its appropriate motion is controlled based on the servo brakes. This paper especially focuses on a motion control algorithm of multiple passive mobile robots for handling a single object in cooperation with a human. By controlling each passive mobile...
We propose a new intelligent walker based on passive robotics that assists the elderly, handicapped people, and the blind who have difficulty in walking. We developed a prototype of the robot technology walker (RT walker), a passive intelligent walker that uses servo brakes. The RT walker consists of a support frame, two casters, two wheels equipped with servo brakes, and it has passive dynamics that...
