A robotic manipulator comprises a plurality of spring compensated joints, each including a four-bar linkage mechanism, a gravity compensating spring, a spring adjustment mechanism, a spring adjustment actuator and an inertial actuator. The gravity compensating spring is coupled between two links of the four-bar linkage mechanism at two different spring attachment points to provide a lifting force opposing a gravitational load force. The spring adjustment mechanism is coupled to alter a position of one of the spring attachment points. The spring adjustment actuator is coupled to move the spring adjustment mechanism to alter the position of the spring attachment point and adjust the amount of lifting force provided by the spring. The inertial actuator is coupled between links of the four-bar linkage mechanism to effectuate rotational movement of the four-bar linkage mechanism and apply an adjustable amount of force to accelerate and manipulate a payload handled by the robotic manipulator.

A robot system includes a robot including leading end, base, and multi-articular arm, and circuitry that controls the atm to move the end based on motion control program specifying transition over time of target position and posture of the end, the transition including correction target portion starting and ending in the transition; controls the arm to move the end in response to guided manipulation applying external force to the robot while the circuitry controls the arm; obtains relative command information based on the target position and posture at start of the correction portion and specifying the target position and posture at points in the correction portion including start and end in the correction portion; and controls the arm to move the end from the position and posture based on the information, beginning at time when movement of the arm controlled by the circuitry in response to the manipulation has ended.

A method includes accessing RGB and depth image data representing a scene that includes at least a portion of a robotic limb. Using this data, a computing system may segment the image data to isolate and identify at least a portion of the robotic limb within the scene. The computing system can determine a current pose of the robotic limb within the scene based on the image data, joint data, or a 3D virtual model of the robotic limb. The computing system may then determine a desired goal pose, which may be based on the image data or the 3D virtual model. Based on the determined goal pose, the computing device determines the difference between the current pose and the goal pose of the robotic limb, and using this difference, provides a pose adjustment that for the robotic limb.

There is provided a pick-and-place system for transferring and installing a contoured composite structure onto a mandrel, in a composite manufacturing system. The pick-and-place system includes a tray station having a tray assembly to hold the contoured composite structure, prior to transfer and installation onto the mandrel. The pick-and-place system further includes an installation station having the mandrel and a pick-and-place assembly. The mandrel is designed to receive the contoured composite structure, and designed to move along a moving manufacturing line, via a conveyor assembly. The pick-and-place assembly includes a gantry assembly, a main beam suspended from the gantry assembly, the main beam having a plurality of end effector assemblies and a plurality of indexing assemblies, a vacuum system coupled to the main beam, a load balancer assembly coupling the main beam to the gantry assembly, and a control system coupled to the pick-and-place assembly, to operably control the pick-and-place-assembly.

A wearable apparatus for assisting muscular strength includes: a main body mechanism extending in a vertical direction of a wearer's torso, and being fixed to a side of a wearer's torso under a wearer's shoulder; a fastening mechanism extending along an extension direction of a wearer's upper arm, and being disposed at and being in contact with a lower surface of the wearer's upper arm; a connecting mechanism having a first end coupled to the fastening mechanism and a second end movably coupled to the main body mechanism so as to be movable with respect to the main body mechanism; and a support mechanism movably coupled between the first end and the second end of the connecting mechanism to apply a support force to the connecting mechanism, and coupled to the main body mechanism and movable with respect thereto.

A rotatable cushioning pick-and-place device primarily comprises a motor, a body, a cushioning module and a pick-and-place module. The cushioning module is disposed in a first chamber of the body and comprises a rotary bearing which is connected to a drive shaft of the motor, and coupled to a driven shaft sleeve through a rotary follower. The rotary follower is driven by the rotary bearing to drive the driven shaft sleeve to rotate, thereby allowing the rotary bearing to displace relative to the driven shaft sleeve axially. The cushioning spring is arranged between the rotary bearing and the driven shaft sleeve. A first sealing ring and a second sealing ring of the pick-and-place module are fixed on the body to cooperatively and air-tightly seal the second chamber.
