An apparatus, system and method capable of providing a bumper capable of providing decreasing reversionary impact forces upon an impacting collider as the bumper is compressed. The apparatus, system and method may include at least a bumper cover; and a scissor mechanism housed within the bumper cover. The scissor mechanism may comprise a forward extension member proximal and having a parallel axis that is at least substantially parallel to a parallel tangential axis of the bumper cover; a rear extension member substantially parallel to the forward extension member, and distal from the flexible bumper; at least left and right long scissor members that are rotatably and slidably associated with respective slots in the forward extension member, and that, are rotatably associated with the rear extension member; and at least left and right short scissor members that are rotatably associated with the front extension member, and that are rotatably associated with a respective one of the left and right long scissor members.

An attachment device includes a robot-engaging portion having a recess formed in an outer surface thereof for receiving a finger of a robot. The attachment device also includes a tool-engaging portion coupled to the robot-engaging portion. The tool-engaging portion is configured to be coupled to a tool that is to be used by the robot to perform a task. A damping member is positioned at least partially between the robot-engaging portion and the tool-engaging portion. The damping member is configured to be adjusted to vary a magnitude of oscillations that are transferred from the tool-engaging portion to the robot-engaging portion.

A collision-detection device for a gripper system of a handling device, with at least two gripping jaws arranged on a flange plate, detects collisions between the gripper system and an object. The device includes a safety device configured to lock the collision-detection device to the gripper system and/or dampen the collision-detection device with the gripper system. The safety device is configured to receive from the flange a change in force and/or a change in torque generated by contact between the gripping jaws and the object. The device further includes a sensor configured to detect a change in distance which exceeds a predetermined permissible change in distance between the flange plate and a reference, the change in distance resulting from the at least one of the change in force and the change in torque.

According to an aspect of the present disclosure, a robot is provided. The robot includes an arm configured to turn around a turning axis and a cover including a first member having first rigidity and a second member having second rigidity higher than the first rigidity, the cover being provided in the arm, the second member being located in a position closer to the turning axis than the outermost periphery of the first member in a plan view from a direction of the turning axis.

A horizontal articulated robot includes: a base; a first arm that is supported by the base so as to be pivotable in a horizontal direction; a second arm that is supported by the first arm so as to be pivotable in the horizontal direction; a shaft that is supported by the second arm so as to be linearly movable in a vertical direction along a longitudinal axis; a stopper that is attached to the shaft and that restricts the movement of the shaft in the vertical direction within a movable range; and a buffering member provided in the second arm, wherein the buffering member is disposed between the stopper and a counterpart member that is provided in the second arm and that faces the stopper in the vertical direction, and buffers an impact exerted on the counterpart member from the stopper.

A robot includes a movable unit displaced in horizontal directions and having a recessed part opening upward in a vertical direction, a connector placed within the recessed part, and a drain part that communicates between a bottom portion of the recessed part and an outside of the movable unit and drains a liquid within the recessed part out of the recessed part.

A robot foot structure for being used in conjunction with the main body structure of a humanoid robot is provided, the robot foot structure being connected to a bottom of the main body structure, wherein the robot foot structure includes a sole plate and a buffering mechanism provided on the sole plate, the buffering mechanism is configured to be connected between the sole plate and the main body structure of the humanoid robot for buffering a load acted on the robot foot structure generated by the weight of the main body structure during walking of the robot foot structure. A load generated by the weight of the main body structure during walking is acted on the buffering mechanism which in turn absorbs an impact resulted from the load as the robot foot structure touches the ground, such that the service life of the robot foot structure can be extended.

An attachment device includes a robot-engaging portion having a recess formed in an outer surface thereof for receiving a finger of a robot. The attachment device also includes a tool-engaging portion coupled to the robot-engaging portion. The tool-engaging portion is configured to be coupled to a tool that is to be used by the robot to perform a task. A damping member is positioned at least partially between the robot-engaging portion and the tool-engaging portion. The damping member is configured to be adjusted to vary a magnitude of oscillations that are transferred from the tool-engaging portion to the robot-engaging portion.

A surgical cart assembly may comprise a base portion; a plurality of wheels coupled to the base portion; a column extending vertically from the base portion; a manipulator arm coupled to an end portion of the column; a stabilization device coupled to the base portion, the stabilization device moveable between a retracted position and a deployed position; an actuation device to cause movement of the stabilization device between the retracted position and the deployed position; and a biasing element coupled to the stabilization device, the biasing element exerting a biasing force to bias the stabilization device toward the retracted position. The stabilization device may comprise a stabilization surface, the stabilization surface contacting the ground surface on which the surgical cart assembly is supported in the deployed position of the stabilization device, and the stabilization surface spaced from the ground surface in the retracted position of the stabilization device.

A screwing device includes a screwdriver and a connection element for coupling the screwdriver to a robot arm. The connection element has a first robot-side transmission element, a second tool-side transmission element, a restoring element arranged between the first and second transmission elements, and a distance measuring element. The two transmission elements can be moved towards each other against a restoring force of the restoring element in an actuation direction. The distance measuring element measures a distance that represents the spacing between the transmission elements in the actuation direction and is used to control the actuating force acting on the screwdriver.
