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...
A novel motion control algorithm was introduced to achieve dance between a man and a passive type robot (PDR), which can not move by itself, but can guarantee higher level of safety in the process of human-robot cooperation. Firstly, the characteristics of servo brake were analyzed, and the motion was divided into 8 states according to the kinematic model and control constraint condition. Then feasible...
A new adaptive motor controller was constructed, and tested on the control of a 2-wheeled balancing robot in simulation and real world. The controller consists of a feedback (PD) controller and a cerebellar neuronal network model. The structure of the cerebellar model was configured based upon known anatomical neuronal connection in the cerebellar cortex. Namely it consists of 120 granular (Gr) cells,...
This paper introduces a passive dance partner robot for realizing the effective human-robot cooperation. Different from the active-type robot with servo motors, the passive robot is controlled by the servo brakes attached to the wheels of the robot and its driving force is the actual force/moment applied by a human. We also propose a control architecture referred to as CAST (Control Architecture for...
In this paper, we introduce a passive mobile robot with casters developed based on the concept of passive robotics. This mobile robot consists of two casters with servo brakes, one passive rigid wheel and a controller. We can manipulate the robot by controlling external force/moment applied by a human based on the control of the servo brakes attached to the casters. We consider the characteristics...
In this paper, we propose an intelligent cane developed based on passive robotics concept for supporting the elderly and the disabled persons who have difficulty walking. The intelligent passive cane (IP Cane) is controlled by servo brakes attached to the wheels and intrinsically safe for humans, because it cannot move unintentionally, i.e., it has no driving actuators. In addition, the IP cane provides...
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. In this paper, we especially focus on a motion control algorithm of multiple passive mobile robots for handling a large object in cooperation with a human. By controlling each passive mobile...
In this research, we develop a passive dance partner robot for realizing the effective human-robot cooperation. Different from the active-type robot with servo motors, the passive robot is controlled by the servo brakes attached to the wheels of the robot and its driving force is the actual force/moment applied by a human. The maneuverability and the controllability of the passive robot are influenced...
In this paper, a passive type dance partner robot referred to as PDR (passive dance robot) is presented to realize ballroom dances in cooperation with a human. PDR is developed based on the concept of passive robotics. Compared to the active type robot actuated by servo motors, the passive type robot can guarantee higher level of safety, since this kind of robot moves passively based on the force...
In this paper, we introduce omni-directional object handling robot system developed based on passive robotics and propose its motion control algorithm for realizing variable motion characteristics of the handling object. Passive object handling robot called PRP (Passive Robot Porter) is controlled by servo brakes attached to the wheels of the robot. By designing the control algorithms of the servo...
