Abstract: 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.

Abstract: 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.
