Abstract:
PROBLEM TO BE SOLVED: To optionally set and vary characteristics of a reaction force applied to an input part. SOLUTION: This system is equipped with an actuator 1 which has a servomotor rotating a screw shaft of a ball screw mechanism and supplies a reaction force to the input part while displacing the input part by the relative movement between a screw shaft and a ball nut through the operation of the servomotor, a load cell 4d which outputs an external force signal showing the strength of the external force applied to the input part, a potentiometer 1g which outputs a position signal showing the position of the input part, a driver 2a which operates the servomotor so that the difference between a position command signal and the position signal is eliminated, a reaction force controller 2b which generates and outputs the position command signal according to the difference between the signal generated by adding a position signal made variable in value according to a reaction force/displacement gradient command signal, a speed signal found from the position signal through differentiation processing and made adjustable in value according to an attenuation factor command signal, and a stationary reaction force command signal and the external force signal, and a computer 3 which outputs the reaction force/displacement gradient command signal, the attenuation factor command signal, and stationary reaction force command signal according to arbitrary settings.
Abstract:
PROBLEM TO BE SOLVED: To obtain a power supply system for a robot, which reconciles the safety and the usefulness of the robot by adjusting its outputtable power, according to the degree of required safety, while materializing a large motor peak current. SOLUTION: This power supply system for robot includes at least one power converting circuit, which includes a plurality of operation modes different in motor output level and gets DC power serving as drive power for motors on each shaft from a commercial AC power source, and a battery, which is charged with electricity from the power converting circuit. In the operation mode large in motor output level among the plurality of operation modes, the output from the battery is connected in parallel with output from the commercial AC power source.

PROBLEM TO BE SOLVED: To enable a person sitting in a wheelchair to be comfortable during moving on a vehicle without spoiling the operability of the wheelchair itself. SOLUTION: A wheelchair vibration-absorbing support device which supports the wheelchair 2 mounted on the vehicle for reducing the vibration of the wheelchair 2 is provided with: a vibration-absorbing mechanism 6 arranged on the floor 1a of an automobile to be erected or flattened for vertically moving a wheelchair support part 6a when erected; a vibration-absorbing mechanism locking part 8 for locking the vibration-absorbing mechanism 6 on the floor 1a standing in a state where the mechanism 6 can be unlocked; a wheelchair locking part 9 which positions the wheelchair 2 on the floor 1a at a position where the wheelchair support part 6a of the mechanism 6 in a standing state and a supported pin 2e of the wheelchair 2 engage with each other in a state where the wheelchair 2 can be unlocked; an acceleration sensor 11 for detecting the vertical movement of the support part 6a; and a vibration-absorbing mechanism controller which controls the mechanism 6 to operate based on the detecting result of the sensor 11 so that the support part 6a may vertically move while supporting the pin 2e so as to cancel the vertical movement of the support part 6a accompanying to the vertical movement of the floor 1a.

Abstract:
PROBLEM TO BE SOLVED: To enable a person riding on a target item oscillated by each of motion bases to physically feel the oscillation of the motion base in synchronism with either an image or an audio sound not in compliance with a bad or good physical state but in compliance with his or her preference even in the case that an oscillation instruction signal common to a plurality of motion bases is sent from a signal source together with either an image signal or an audio signal. SOLUTION: There is provided a controller for motion bases in which a seat of item on which a person rides is oscillated by an actuator 1, wherein the actuator 1 is operated in response to a common motion signal sent from a broadcasting station B to a plurality of motion bases M1, M2 together with an image signal and an audio signal characterized in that there are provided a motion control unit 6 for outputting a drive signal for driving the actuator 1, and a riding comfortable feeling adjuster 5 mounted on the motion bases M1, M2, operated by a person seated on a seat unit for changing the motion signal sent from the broadcasting station B and supplying it to the motion control unit 6.

Abstract:
PROBLEM TO BE SOLVED: To provide technology to solve difficulty of routing of various wiring in the inside of a mobile robot. SOLUTION: A structure to bury the flexible printed wiring 152 in a layer structure is adopted as an outer-sheath 141 of an upper leg part 121 on the man type two-leg walking mobile robot. Wiring is carried out by installing the outer-sheath 141. In this structure, it is possible to reduce the wiring in the upper leg part 121 by an amount of the wiring buried in the outer-sheath 141.
