摘要： A robotic system includes a robot adapted for moving a payload in proportional response to an input force from an operator, sensors adapted for measuring a predetermined set of operator input values, including the input force, and a controller. The controller determines a changing stiffness value of the operator using set of operator input values, and automatically adjusts a level of control sensitivity over the robot using the stiffness value. The input values include the input force, a muscle activation level of the operator, and a position of the operator. A method of controlling the robot includes measuring the operator input values using the plurality of sensors, processing the input values using the controller to thereby calculate the stiffness value, and automatically adjusting the level of control sensitivity over the robot using the stiffness value. A specific operator may be identified, with control sensitivity being adjusted based on the identity.

摘要： A method of joining workpieces includes rotating a friction stir rivet via a mandrel and driving the rivet into the workpieces causing frictional heating between the rivet and the workpieces and causing the materials of the workpieces to soften, thereby providing a fiction stirred displaceable path for the rivet to traverse, and driving the rivet along the displaceable path until the rivet mandrel pierces through the workpieces and a cap of the rivet is seated against the workpieces. Subsequent to seating the cap, further rotation of the mandrel is stopped and the workpieces are allowed to cool and harden. An axial load is then applied to the mandrel sufficient to provide mechanical loading between the rivet body and the workpieces. A resultant volume of displaced material from the workpieces is fixedly attached to the workpieces, thereby avoiding the creation of a potentially detachable slug of the displaced material.

摘要： A friction stir nut is disclosed. The friction stir nut includes a body, a cap, and an anti-rotation feature. The body has an elongated cylindrical shank extending between a first end and a second end, the cap being disposed at the second end, and the anti-rotation feature being disposed at the cap and/or an outer surface of the body.

摘要： Method and apparatus is provided for monitoring the installation of a blind rivet to attach together top and bottom members. The blind rivet installation tool includes a housing having an anvil seated on the rivet head. A collet is reciprocable within the tool housing and carries jaws for gripping the mandrel of the blind rivet. Retraction of the jaws by the collet displaces the jaws and the mandrel axially and causes the mandrel head to axially collapse and radially expand the hollow shank of the blind rivet into engagement with the bottom member so that the rivet attaches the top member and the bottom member. A cut off tool is actuated by an actuator to cut off the mandrel flush with the rivet head. Transducers and a process controller monitor the installation process and actuate the cut off blade upon determining that the blind rivet is properly installed.

摘要： A pallet includes a platform and a plurality of support assemblies located at multiple positions on the platform. One support assembly is associated with each location of the component to be supported. Each support assembly has a linkage assembly to support and enable movement of a support element. The support assemblies also each include multiple bases secured to the platform, to position the support element in a desired location for each version of a component. A locking mechanism on each base prevents movement of the support element when in the desired position. To configure the pallet for another version of the component the locking mechanism is released, the support element is moved to another base and the locking mechanism for that base is secured.
