Abstract: A robotic finger structure includes a proximal phalanx; a middle phalanx rotatably connected to one end of the proximal phalanx; a distal phalanx rotatably connected to one end of the middle phalanx and defining a distal phalanx opening in a front side thereof and at one end adjacent to the middle phalanx; a connecting rod having opposite ends that are rotatably connected to the proximal phalanx and the distal phalanx, and an actuating assembly to drive the middle phalanx to rotate with respect to the proximal phalanx. The connecting rod includes a first angled segment having a first recess facing a back side of the middle phalanx. When the distal phalanx is flush with the middle phalanx, the first angled segment passes through the distal phalanx opening, and a first end of the distal phalanx opening extends into the first recess.

Abstract: An elevation device includes a mounting frame, a rotary actuator fixed to the mounting frame, a shall connected to the rotary actuator and rotatable with respect to the mounting frame, a drive bar slidably connected to the mounting frame, and a connecting member fixed to the shaft. The shaft defines a helical groove in a lateral surface thereof. The drive bar includes a post that is movably fit in the helical groove. The mounting frame, the shaft and the drive bar constitute a conversion mechanism that converts rotation of the shaft into linear motion of the drive bar. The drive bar is slidable with respect to the mounting frame along a direction that is parallel to an axis of rotation of the shaft.

Abstract: A robot movement control method and apparatus as well as a robot using the same are provided. The method includes: calculating a distance between a robot and a Ultrawide Band (UWB) base station; configuring an internal coordinate system according to a preset position of the UWB base station, and calculating a coordinate of the robot in the internal coordinate system according to a distance between the UWB base station and the robot; combining the coordinate of the robot in the internal coordinate system with localization information of an odometer provided on the robot to obtain a combined robot coordinate; and controlling the robot to move in accordance with a preset target position according to the combined robot coordinate. In such manner, UWB base station localization can be used to control the movement of a robot in a limited scene.

Abstract: The present disclosure provides a robot recharge docking method. The method includes: obtaining current radar data of a radar of a robot for a scanned obstacle; obtaining a position of a target object by analyzing the current radar data; controlling the robot to move to a predetermined position around the target object; determining whether infrared carrier data is received by the robot recharge docking apparatus from the target object; determining that the target object is a charging station upon receiving the infrared carrier data from the target object; and docking the robot at the target object to charge if the target object is the charging station. In the above-mentioned manner, the present disclosure can prevent the robot from taking an obstacle similar to a charging station in shape as the charging station to dock at, thereby ensuring the safety of the automatic recharging of the robot.
