A protection apparatus for a manipulation device on a handling device, in particular on a handling robot. The manipulation device has at least one movably developed manipulation element and at least one overload protection which induces an evasion of the manipulation device when a trigger force on the manipulation device is exceeded. The overload protection has at least one magnetic element, which fixates the manipulation device in a setpoint position at forces below the trigger force.

PASSIVE COMPLIANCE MECHANISM

A passive compliance mechanism includes a fixing member, a base and a stiffness adjustment assembly. The base is installed on the fixing member, and includes two notches and an elastic slice. A first end of the elastic slice is connected with the base. A second end of the elastic slice is located near the outer periphery of the fixing member. The stiffness adjustment assembly includes a linear guide, a sliding block and two stopping blocks. The linear guide is installed on the fixing member. The sliding block is movably installed on the linear guide. The two stopping blocks are disposed on the sliding block and synchronously moved with the sliding block. The two stopping blocks are contacted with two opposite sides of the elastic slice to clamp the elastic slice. A stiffness of the base is adjustable according to a clamped position of the elastic slice.

Torsional series elastic actuator

A rotary-type series elastic actuator (SEA) for use in robotic applications. The SEA including a motor, gear transmission assembly, spring assembly, and sensors. In one example, a robotic joint may include the SEA as well as two links coupled with each other at the joint assembly. The two links may be designated as input and output links. Each link may have a joint housing body which may be concentrically connected via a joint bearing so that they freely rotate against each other. The housing frame of the SEA may be fixed at the joint housing body of the input link while the output mount of the spring assembly of the SEA may be concentrically coupled with the joint housing body of the output link. The rotation of the motor rotor causes the rotation of the output link with respect to the input link plus spring deflection of the spring assembly. When an external force or torque are applied between the two links, a control action of a control loop may cause a rotation and motive force of the motor that lead to the deflection of the spring assembly to balance with the external force/torque and inertial force from body masses moving together with the links.

HAND AND ROBOT SYSTEM

A hand includes a hand body in which a predetermined first reference axis is defined, a gripper in which a predetermined second reference axis is defined and which grips a workpiece, and a coupler that couples the gripper to the hand body. The coupler includes at least one of a decentering supporter that supports the gripper such that the second reference axis is capable of being decentered with respect to the first reference axis, or a tilt supporter that supports the gripper such that the second reference axis is capable of being tilted with respect to the first reference axis.
