Robot for gripping and/or holding objects
In a robot (1) for gripping and/or holding objects (2), in particular workpieces, tools or carrier parts, the robot comprising: at least one robot arm (3, 4, 5) which is supported on a support frame (19) and is movable in space in at least one translational and/or rotational degree of freedom, a gripping and/or holding device (6), on which the respective object (2) is supported in a positionally oriented manner and/or held in a rotational arrangement, at least one electric motor (9) provided in the gripping and/or holding device (6), by means of which a torque and/or a clamping force is generated which acts on the object (2), and a drive shaft (24) mounted in the robot arm (5), which is coupled in a driving manner to the gripping and/or holding device (6), preferably in such a way that the gripping and/or holding device (6) rotates about its own longitudinal axis (6),
the gripping and/or holding device (6) arranged at the free end of the robot arm (5) should be freely movable in space, so that rotation about its own longitudinal axis (6) can be carried out as often and as quickly as desired. This is achieved in that an interface (31) is provided between a free end (10) of the robot arm (5) at the end and the gripping and/or holding device (6), which interface (31) is bridged by a coupler (25) fixed in a non-rotating arrangement to the robot arm (5) and by a flange (11) adapted thereto, which flange (11) is connected in a non-rotating arrangement to the gripping and/or holding device (6) and the drive shaft (24), in that a first inductively operated transceiver (12) is provided in the coupler (25), which transceiver (12) is connected to a power source (15) via an electrical line (14) fed to the robot arm (5), in that a second inductively operated transceiver (13) is provided in the flange (11), which is connected to the electric motor (9) in the gripping and/or holding device (6) via electrical lines (14), and in that an air gap (21) is provided between the coupler (25) and the flange (11) as a component of the interface (31).
Clutched joint modules having a quasi-passive elastic actuator for a robotic assembly
A method for operating a robotic joint of a robotic system comprising selectively operating a clutch mechanism of a clutched joint module in an engaged state to cause a quasi-passive elastic actuator to enter an elastic state, the clutched joint module operating about and defining a joint of the robotic system. The method comprising effecting a first rotation of the joint to cause the quasi-passive elastic actuator to store energy during at least a portion of the rotation of the joint. The method comprising effecting a second rotation of the joint and causing the stored energy from the quasi-passive elastic actuator to be released in the form of an augmented torque applied to an output member of the clutched joint module. The method comprising selectively operating the clutch mechanism in a disengaged state to cause the quasi-passive elastic actuator to enter an inelastic state. The method comprising effecting a third rotation of the joint, wherein the quasi-passive elastic actuator facilitates a free swing mode of the clutched joint module and the joint.
MULTI-TURN DRIVE ASSEMBLY AND SYSTEMS AND METHODS OF USE THEREOF
Disclosed herein are multi-turn drive assemblies, systems and methods of use thereof. The multi-turn drive assemblies enable a robot link member to have a maximum rotation of at least 360 degrees about an axis. The multi-turn drive assemblies can be incorporated into a robot arm for enabling 360 degrees rotation of one or more link members about an axis. The robot arm may be located in a transfer chamber of an electronic device processing system. Also disclosed are methods of controlling the multi-turn drive assemblies and related robots.
Rotational joint assembly for robotic medical system
An example rotational joint assembly for a robotic medical system, the rotational joint assembly comprising at least one arm segment and a rotational joint provided at one end of the arm segment. The rotational joint is to allow the arm segment to rotate about a rotational axis. The rotational joint comprising a brake to lock rotation of the arm segment at the rotational joint and an actuator to selectively engage or disengage the brake. The actuator comprising a cam having two stable regions separated by two transition regions, the two stable regions comprising a first stable region corresponding to engagement of the brake and a second stable region corresponding to disengagement of the brake.
Articulation mechanisms for robotic surgical tools
A robotic surgical tool includes a drive housing having a first end and a second end, at least one spline extending between the first and second ends and including a drive gear that rotates with rotation of the spline, and a carriage movably mounted to the spline. An elongate shaft extends from the carriage and through the first end, an end effector is arranged at a distal end of the elongate shaft, and a wrist interposes the end effector and the distal end of the shaft. An activating mechanism is housed in the carriage and operatively coupled to the drive gear such that rotation of the drive gear correspondingly actuates the activating mechanism and thereby causes the wrist to articulate the end effector in at least one plane.
PART MANIPULATOR FOR ASSEMBLY MACHINE
A part manipulator includes a robot arm movable in three-dimensional space between a pick station and a place station. The part manipulator includes an end effector coupled to a distal end of the robot arm. The end effector includes a rotation platform rotatable between a first position and a second position. The end effector includes a part gripper coupled to the rotation platform movable between a releasing position and a holding position. The part gripper is configured to hold a part in the holding position. The part gripper is rotated by the rotation platform as the rotation platform is rotated from the first position to the second position to move the part from a picking orientation to a placing orientation. The end effector picks up the part in the picking orientation at the pick station. The end effector releases the part in the placing orientation at the place station.
ARTICULATED MULTI-LINK ROBOTIC TAIL SYSTEMS AND METHODS
An articulated multi-link robotic tail (MLRT) system is provided comprising a rigid housing, an actuation unit coupled to the rigid housing, and an MLRT having a proximal end that is coupled to the rigid housing and a distal end opposite the proximal end. The MLRT comprises N segments, where N is a positive integer that is greater than or equal to one. Each segment comprises i links, where i is a positive integer that is greater than or equal to two. Each link is mechanically coupled to an actuator of the actuation unit and capable of being actuated by the actuator to which it is mechanically coupled to adjust a pitch, yaw and roll of the MLRT. The articulated MLRT system is well suited for being integrated with a mobile robot to assist in stabilizing and maneuvering the mobile robot.
