An industrial robot system includes a manipulator with a drive chain including a motor unit. A controller in the industrial robot system is electrically connected to the drive chain by a set of power transmission lines and is operable to transmit electrical power on the set of power transmission lines so as to impart a controlled movement of the manipulator. A supervision sensor is arranged in the manipulator and configured to sense a property of the manipulator. The supervision sensor is electrically connected to at least a subset of the power transmission lines for transmission of sensor data representing the property to the controller.

A seven-degrees of freedom modular robotic device is provided for controlling an instrument, e.g. a bone-drilling or milling device with a precision of about 50 μm and maximum force of 50 N. The robotic device is a serial kinematic chain of six rotational degrees of freedom and one translational degree of freedom.

A braking device for a drive device of a joint between two links of a robot arm including a brake activating device and a locking element, wherein the brake activating device is designed to bring the locking element into engagement with a rotor of the drive device as required in order to halt rotation of the rotor, the locking element being designed as a bolt and the braking element being designed as a braking star with webs which have a defined impact surface for the bolt.

A brake piloting system including a robotic device having at least one movable element, at least one brake which, when activated from an open configuration to an activated configuration, enables a deceleration or immobilization of the at least one movable element, at least one position sensor aimed at measuring a real time position of the at least one movable element and at least one the microcontroller being configured to activate in real time the at least one brake into a determined configuration.

A welding manipulator for holding a welding head comprised of a base, rotating column and swivel boom is shown. The column includes a novel rotating apparatus comprised of a lockable rotary bearing, rotary housing, clamp shell and brake handle. In the unlocked position, the column rotates smoothly and easily around the base. In the locked position, the clamp shell engages and disengages the rotary bearing, thus locking the column in place.

The present welding manipulator also discloses a boom attached to the column with a swivel mount. This swivel mount allows the boom to be locked into an operating position or a shipping position for more compact shipping or storage. The disclosed welding manipulator also includes tracks on the column and a motorized screw drive to vertically position the boom.

There is provided a mechanical avatar assembly for use in a confined space in a structure. The mechanical avatar assembly includes a rail assembly for attachment to an access opening to the confined space. The rail assembly includes two or more rail segments coupled together to form an elongated base having a rail and a gear rack extending along a length of the elongated base. The rail assembly further includes a carriage portion coupled to the rail, and movable relative to the rail, and a drive assembly coupled to the carriage portion and to the gear rack, to move the carriage portion along the rail. The mechanical avatar assembly further includes an articulating avatar arm coupled to, and movable via, the carriage portion. The mechanical avatar assembly further includes an image capturing device.

A robot joint structure includes a first member and a second member that are hollow, an actuator that rotates the second member about a fourth axis relative to the first member, and a brake mechanism capable of braking rotation of the second member relative to the first member. The actuator includes a motor accommodated within the first member, a speed reducer that reduces the speed of rotation of a motor shaft of the motor and that transmits the rotation to the second member, a first gear provided at the motor shaft, and a second gear provided in the speed reducer and engaged with the first gear. The brake mechanism includes a brake body accommodated within the first member, a brake shaft capable of being braked by the brake body, and a third gear provided at the brake shaft and engaged with the second gear.

A motorized joint unit of a mechanism has a rotor assembly and a stator assembly operatively assembled and configured for being secured to respective links of the mechanism, the rotor assembly and the stator assembly respectively including a rotor and a stator concurrently operable to cause a rotation of a rotor of the rotor assembly relative to a stator of the stator assembly about a rotational axis, the rotor assembly including a shaft. A brake assembly has a friction clutch assembly including a spoke disk having at least one radial projection. A brake actuator has a plunger displaceable into a path of movement of the radial projection to cause a braking force to be applied by the friction clutch assembly to the shaft when contact is made between the radial projection and the plunger. The brake assembly is connected to the motorized joint unit for the braking force to brake a rotation between the rotor assembly and the stator assembly.

A collaborative robot operation apparatus includes an operation unit that is operated by an operator in direct teaching of a robot including a cylindrical outer surface at least in a part, a communication unit that communicates operation information to the operation unit, to a control apparatus of the robot, and an attachment portion that detachably attaches the operation unit on the outer surface of the robot. The operation unit includes a rotation stopping portion between the outer surface of the robot and the operation unit.

There is provided a rotary actuator which makes it possible to operate a regulation release of a regulating member from the outside of a case body when the regulating member is in a regulation position, and can prevent an unexpected regulation release, and a robot. A drive mechanism of a joint part has a compression coil spring for biasing a regulation pin toward a regulation position, and a solenoid for moving the regulation pin 32 toward a regulation release position. A through hole is formed in a case body at a portion facing the upper end portion (the other end portion opposite to one end portion abutting against the regulation pin) of a plunger of the solenoid, and the upper end portion of the plunger is positioned on the inside of the case body while the regulation pin is in the regulation position.
