摘要： Robotic systems and methods are provided with an end effector having lockable compliance. A robotic system for manipulating a workpiece includes an arm having a pair of sections connected by a joint assembly, with a lock disposed in the joint assembly. A gripper is connected on the arm and is configured to alternately grip and release the workpiece. A controller operates the lock to alternately lock and unlock the joint assembly. The gripper holds the workpiece during a deformation of the workpiece, while the controller may unlock the lock to allow movement of the joint assembly to relieve forces on the arm arising during a deformation of the workpiece.

摘要： An electrical connector assembly includes a pair of electrical connectors for electrically connecting to one another to close an electric circuit. The assembly further includes a connection indicator attached to one or more of the electrical connectors. The connection indicator generates a feedback, in response to the electrical connectors being one of connected to one another and disconnected from one another. The connection indicator is separate from the electric circuit, and the feedback is at least one of a radio frequency signal (RF signal), an electronic signal, a visible light, and an acoustic signal.

摘要： A method of laser welding a workpiece stack-up (10) that includes at least two overlapping steel workpieces (12, 14) comprises directing a laser beam (40) at a top surface (26) of the workpiece stack-up to form a keyhole (56) surrounded by a molten steel weld pool (58). The laser beam is conveyed along a predefined weld pattern that includes one or more nonlinear inner weld paths (66) and an enclosed outer peripheral weld path (68) surrounding the one or more nonlinear inner weld paths. During conveyance of the laser beam along the one or more nonlinear inner weld paths, the keyhole fully penetrates through the workpiece stack-up from the top surface of the stack-up to the bottom surface (28) of the stack-up. The method produces weld joints between the steel workpieces that do not have an intentionally imposed gap formed between their faying surfaces.

摘要： The present invention relates to a method and apparatus for limiting the contact force between a moving device and another object, using a parallel mechanism and torque limiters where the threshold force to activate the force limiting mechanism is not related to the configuration of the moving device or the location of the contact force relative to the activation point of the force limiting mechanism, and where the mechanism may be configured for one, two or three degrees of freedom. A counterbalance mechanism is also provided to counteract gravity load when the force limiting mechanism is configured for three degrees of freedom and responsive to contact forces including a vertical element. In particular, the invention relates to a method and apparatus for limiting the contact force between a moving robotic device and a contactable object.

摘要： A method of inferring intentions of an operator to move a robotic system includes monitoring the intention of the operator, with a controller. The intention of the operator is inferred to be one of a desired acceleration and a desired deceleration. The intention of the operator is also as a desired velocity. Admittance parameters are modified as a function of at least one of the inferred acceleration, deceleration, and velocity.

摘要： A robotic system includes a support structure, a platform, a center serial chain, outer serial chains, motors, a sensor, and a control module. The center serial chain connects a center of the platform to the support structure and includes first joints connected to a linear sliding shaft. The outer serial chains are disposed radially outward of the center serial chain. Each of the outer serial chains includes second joints connecting a bar to the platform and the supporting structure. The motors are connected to the outer serial chains. The sensor is connected to the platform and detects at least one of force or torque applied by a human operator on the platform and generates a signal indicative thereof. The control module controls the motors based on the signal to assist the human operator in at least one of moving or rotating the platform.

摘要： Robotic systems are provided for flexibility in assembly operations. A robotic system includes a suction module having a front side with a face shaped to match a mating component and a rear side with a coupling for a suction line. Openings extend through the face. The suction module defines internal passages connecting the coupling with the at least one opening through the face. An end-effector has a base plate, a mounting plate selectively moveable relative to the base plate, and a clamp. The suction module is selectively mounted to the mounting plate and releasably secured by the clamp. An actuator is mounted to selectively move the mounting plate and the suction module relative to the base plate.
