An automated assembly station includes a mobile platform for holding a first workpiece, a robot having a moveable arm, and a controller. The moveable arm includes a load cell and a gripper that is adapted to grasp a second workpiece. The robot is operable to use the moveable arm and gripper to insert the second workpiece into a locked position on a mating part of the first workpiece. The load cell is operable to measure an amount of insertion force used to insert the second workpiece into the locked position. The controller is configured to record the insertion force and trigger an alarm in response to the insertion force exceeding a predesignated threshold insertion force.

A flexible end-effector for a robot includes a frame and a clamp assembly movably coupled to the frame. As such, the clamp assembly is movable relative to the frame along a first direction, wherein the clamp assembly includes a locator and a clamp movably coupled to the locator. The clamp assembly also includes pneumatic actuator coupled to the clamp to move the clamp between an open position and a closed position. The flexible end-effector further includes linear motion slides coupled between the clamp assembly and the frame to allow the clamp assembly to move linearly relative to the frame along the first direction. Further, the flexible end-effector includes a servomotor assembly coupled to the linear motion slide to actuate the linear motion slide. The servomotor assembly includes a servomotor and a motor controller integrated with the servomotor.

Example systems and methods are disclosed for determining tool offset data for a tool attached to a robot at an attachment point. The method may include controlling the robot to contact a reference object with the tool. The reference object may be a rigid object with a known location. A force feedback sensor of the robot may indicate when the tool has contacted the reference object. Once contact is made, data indicating robot position during tool contact may be received. Additionally, the robot may temporarily stop movement of the tool to prevent damage to the tool or the reference object. Next, tool offset data may be determined based on the position of the reference object relative to the robot and the received robot position data. The tool offset data may describe the distance between at least one point on the tool and the attachment point.

A robot in which two members constituting a joint shaft and supported in a relatively movable manner are each provided with a V-shaped groove having two sloped inner surfaces intersecting each other at a linear groove bottom extending orthogonally to a movement direction, or a V-shaped protrusion having two sloped outer surfaces intersecting each other at a linear ridge extending orthogonally to the movement direction. When the two members of the joint shaft are disposed in a predetermined operational position, the groove bottoms, the ridges, or the groove bottom and the ridge are disposed in alignment with each other.

A continuum robot comprising: a first segment defining a first end and a second end, the first segment including a first actuator coupled to the second end and configured to control movement of the second end relative to the first end; and a first elastic strain sensor coupled to the first segment and positioned between the first end and the second end, the first elastic strain sensor being configured to provide a first output signal associated with the movement of the second end relative to the first end.

To perform a tool exchange in a medical robotic system, tool is retracted back into an entry guide from a deployed position and pose so that an assistant in the operating room may replace it with a different tool. While the tool is being retracted back towards the entry guide by user action, its configuration is changed to an entry pose while avoiding collisions with other objects so that it may fit in the entry guide. After the tool exchange is completed, a new tool is inserted in the entry guide and extended out of the guide by user action to the original position of the old tool prior to its retraction into the entry guide while the tool's controller assists the user by reconfiguring the new tool so as to resemble the original deployed pose of the old tool prior to its retraction into the entry guide.

A process system includes a detection device that detects a rotation angle of a workpiece when a robot grips the workpiece. The control device includes a storage unit that stores a reference rotation angle serving as a criterion for the rotation angle of the workpiece, and an error calculation unit that calculates a rotation error relative to the reference rotation angle in the rotation angle of the workpiece detected by the detection device. The control device corrects the rotation angle of the fixture based on the rotation error so as to correspond to the rotation angle of the workpiece detected by the detection device when the robot transfers the workpiece to the fixture.

A controller of a robot includes a storage that stores a main program, a point sequence containing statements arranged in sequence and containing kind information identifying control details to a work tool and coordinate information on a point on a work-piece, a point kind definition describing the control details identified by the kind information, and containing reference information to refer adjustment information for each work tool, and the adjustment information for each work tool prepared so as to correspond to the reference information, an executing unit executing the main program, and a referring unit referring the adjustment information based on the reference information when the point kind definition in the point sequence is inherited during the execution by the executing unit, and applying the adjustment information to the control details.

A supernumerary robotic limb (SRL) system can include a plurality of rigid links, a joint that connects one rigid link to another rigid link in the plurality of rigid arms, and two variable stiffness actuators (VSAs) configured to drive the plurality of rigid links in order to complete at least one task. The VSAs can exhibit infinite rotation and infinite stiffness. The VSAs can include an output link. Additionally, the VSAs can include a set of elastic elements mounted on the output link. The VSAs can include an input link configured to provide kinetic energy for the output link. The VSAs can include a dynamic chassis configured to connect with the input link. Additionally, the VSAs can include a stiffness adjustor included in the dynamic chassis and configured to adjust an elastic transmission between at least one elastic element of the set of elastic elements and the output link.

An apparatus includes a spindle platform; a traversing platform configured to move in a first direction; a lift system connected to the spindle platform and the traversing platform, the lift system configured to move the spindle platform in a second direction perpendicular to the first direction; a movable arm connected to the spindle platform, the movable arm including a first link connected to the spindle platform, a second link connected to the first link, and a third link connected to the second link, and a first actuator connected to the spindle platform and configured to cause a rotation of the first link, and a second actuator in the movable arm and configured to cause a rotation of the second link. The first actuator extends from the spindle platform into the first link to occupy a combined thickness of the spindle platform and the first link.
