According an embodiment, a work support device includes an arm unit, a brake unit, a state determination unit, and a brake control unit. The arm unit includes a grasping part configured to grasp an object, a plurality of joint parts, and a plurality of link parts actuatably coupled through each joint part. The brake unit is provided to at least one of the joint parts to restrict actuation of the arm unit. The state determination unit determines the state of the arm unit. The brake control unit controls the brake unit to restrict actuation of the arm unit in accordance with the state of the arm unit.

The present disclosure discloses a rotary joint electromagnetic locking device and a rotary joint, the rotary joint electromagnetic locking device comprising a first electromagnetic sucker, a sliding plate, a rotary plate, a connecting shaft connecting the first electromagnetic sucker and the sliding plate, and a second electromagnetic sucker, different from the prior art. When the first electromagnetic sucker and the second electromagnetic sucker have no adsorption force, the sliding plate and the rotary plate can be locked to each other; when the second electromagnetic sucker has an adsorption force, the rotary plate or the first electromagnetic sucker is adsorbed by the second electromagnetic sucker, making the sliding plate and the rotary plate to be further locked; when the first electromagnetic sucker has an adsorption force, the sliding plate can be adsorbed to the first contact surface of the first electromagnetic sucker, making the sliding plate released from the rotary plate.

A system and method of providing feedback during manual joint positioning includes a computer-assisted device having an articulated structure including a joint and a control unit coupled to the articulated structure. To provide feedback to a user during manual positioning of the joint by a user, the control unit is configured to determine a first target position for the joint, release a brake associated with the joint when the joint is moving toward the first target position, apply the brake when the joint is moving away from the first target position, and change the first target position to a second target position when the joint is at the first target position.

A refuse vehicle includes a chassis, tractive elements, a lift apparatus, and a reach assembly. The tractive elements couple with the chassis and support the refuse vehicle. The lift apparatus includes a track and a grabber assembly. The track includes a straight portion and a curved portion. The grabber assembly releasably grasps a refuse container and ascends or descends the track to lift and empty refuse into a body of the refuse vehicle. The reach assembly includes an outer member, a first extendable member, and a second extendable member. The first extendable member is received within an inner volume of the outer member and translates relative to the outer member. The second extendable member is received within an inner volume of the first extendable member and translates relative to the first extendable member. The lift apparatus is fixedly coupled at an outer end of the second extendable member.

A delta robot includes a robot base, an end effector carrier that can be positioned in space, and three parallelogram articulated couplings which connect the end effector carrier to the robot base and are designed to connect the end effector carrier in a displaceable manner while maintaining its orientation in space relative to the robot base. Each parallelogram articulated coupling can be displaced, driven by a motor, to automatically move the end effector carrier, wherein each motor can be braked by means of a brake in order to automatically stop the end effector carrier and/or to hold the end effector carrier in its present position. The end effector carrier comprises at least one input device connected to the brakes by control technology and designed to release the brakes in an actuated switching state of the input device such that the end effector carrier is manually displaceable.

A method for recovery of a frictional brake device of an industrial device, the method including executing a recovery operation, the recovery operation including at least one movement of a second member of the industrial device relative to a first member of the industrial device, while engaging the brake device to apply braking energy to the movement; monitoring an actual value related to braking energy of the brake device during the recovery operation, the actual value being not related to speed of the movement; and stopping the recovery operation when the actual value reaches the at least one target value. An industrial device is also provided.

The invention relates to a drive (1; 101) of a machine (2) comprising a drive motor (3) for driving a rotatable shaft (5) of the machine (2) around a shaft axis of rotation (4), and comprising a clutch unit (10) in operative connection with the drive motor (3) and the shaft (5) for compensating for a relative movement (11) between the shaft (5) and the drive motor (3). The drive motor (3) has a rotor part (35) surrounding the shaft (5) on which a clutch rotation part (18A) of the clutch system (10) is mounted to be rotatable around the shaft axis of rotation (4), wherein the rotor part (35) is arranged at least partially engaging in the clutch rotation part (18A) in such a way that the clutch rotation part (18A) is mounted radially movably on the rotor part (35).

A robot includes a robot housing containing a robot control apparatus that controls the robot having a motor, a brake that brakes the motor by short-circuiting between power lines for supplying electric power to the motor, and a conversion element that converts a current generated by braking of the motor by the brake into heat, wherein the conversion element is attached to the robot housing.

A valve operating device includes a mounting for attachment to a vehicle and an elongate arm, the free end of which is only moveable across the underlying ground. The joints of the arm pivot around vertical axes and the arm is locked into a desired orientation by a brake at each joint. A valve turning machine is at the free end of the arm. The brakes are engaged and released by a control on the valve turning machine.

A suspension device of suction pads of industrial manipulators is described, which can also be defined as level compensator. The device comprises a body and a telescopic stem or passing through the body, and sliding between an extended position and a retracted position. A spring constantly applies a thrust on the stem to bring it to the extended position. The device is hollow to allow the suction of the air from the suction pad constrained to the stem. Advantageously the suspension device comprises a brake which can be activated to brake, i.e., slow down, the stroke of the stem or stop it completely.
