Abstract: An operation method of a robot for leading a follower to a destination within an open space includes: calculating a distance between the follower and the robot; when it is determined that the distance is not greater than a threshold, determining a pre-movement location of the robot in the open space and an orientation of the robot, and calculating a linear speed and an angular speed for the robot based on the pre-movement location and the orientation of the robot and the destination; moving according to the linear speed and the angular speed; determining whether the robot has arrived at the destination according to the current position; and repeating the previous steps when it is determined that the robot has not arrived at the destination.

Abstract: A power supply system with hydrogen fuel cell is provided, comprising a hydrogen fuel cell module converting hydrogen fuel into electrical power for outputting. A boost charging module electrically connected to the hydrogen fuel cell module receives, boosts and converts the electric power into charging power. At least two battery packs connected in parallel are electrically connected to the boost charging module and an external load respectively. When one of the battery packs discharges the external load, the other selectively receives charging power from the boost charging module. A control module electrically connected to the above controls the boost charging module to receive electrical power and convert it into charging power and controls the battery packs to alternate performing discharging the external load and charging from the boost charging module repeatedly by turns. The present invention combines hydrogen fuel cells to provide an innovative power supply system.
