全方向移動自律走行ロボットの安全速度監視モジュール

抄録

The safety measures of the omni-directional autonomous mobile robots for work support have been subjects. Authors developed the speed monitor module which can reduce a collision risk with human and other safety-related objects by adding to a robot's control system. The developed speed monitor module calculates a robot's running speed by detecting the number of rotations of four wheels of the omni-directional mobile robots, and outputs the signal for protection area selection of a safety laser scanner according to speed. The performance level of the module according to ISO 13849-1 was evaluated, and also the improvement of a performance level was considered.
