A robot end effector for dispensing an extrudable substance comprises a chassis, cartridge bays, attached to the chassis and each shaped to receive a corresponding one of two-part cartridges, and a manifold, comprising a manifold outlet, manifold inlets, and a valve inlet. When the two-part cartridges are received by the cartridge bays, the manifold inlets are in fluidic communication with corresponding ones of the two-part cartridges via static mixers, attached to cartridge outlets of the two-part cartridges. The robot end effector additionally comprises a head assembly, comprising pairs of fittings, configured to selectively supply compressed air from a pressure source to the two-part cartridges when the two-part cartridges are received by the cartridge bays, so that contents of the two-part cartridges are concurrently extruded through the cartridge outlets.

A vehicle for uneven terrain includes a main frame; a front wheel assembly disposed in front of the main frame with a front wheel; a rear wheel assembly disposed behind the main frame with a rear wheel; a wheelbase adjuster configured to adjust a wheelbase between the front wheel and the rear wheel; a first side wheel assembly disposed on one side of the main frame with a first side wheel; a second side wheel assembly disposed on another side of the main frame with a second side wheel; a front wheel torque transmitter configured to interlock vertical movements of the front wheel and the first side wheel; a rear wheel torque transmitter configured to interlock vertical movements of the rear wheel and the second side wheel; and a stabilizer configured to support the first side wheel assembly and the second side wheel assembly.

A robot (100) includes a resistance circuit (60) configured or programmed to perform a control to reduce a braking force of a dynamic brake by changing a resistance value of a resistance component (63) with respect to a power supply path (61) when motors (30) are stopped at an abnormal stop.

A drive device including at least one motor and at least one additional drive component from the group of a transmission, a torque converter, a clutch and/or a brake, wherein the at least one motor and/or the at least one additional drive component includes a control means which changes the torque transmission and which includes at least one illuminant and a material that influences the torque transmission and that includes at least one light-stabilized dynamic material (LSDM). The control means is configured to change the torque transmission by actuating the illuminant, which radiates onto the light-stabilized dynamic material (LSDM). A robot includes at least one such drive device.

A vessel cleaning device and method includes an armored chassis with track members operable independently by first and second pneumatic drive systems, and a remotely controllable arm. A plurality of nozzles disposed on the arm are configured to rotate while spraying high pressure liquid in mutually opposed directions when the arm is extended. The device is sized and shaped to pass through a 24-inch opening in the vessel when the arm is collapsed, and the track members and the arm are controllable remotely by an operator external to the vessel. Once the device has passed through the 24-inch opening into the vessel, the arm is movable into the extended position, and the device is movable within the vessel while the nozzles spray liquid along a notional circumference to remove waste materials from an interior surface of the vessel.

A rotary-type series elastic actuator (SEA) for use in robotic applications. The SEA including a motor, gear transmission assembly, spring assembly, and sensors. In one example, a robotic joint may include the SEA as well as two links coupled with each other at the joint assembly. The two links may be designated as input and output links. Each link may have a joint housing body which may be concentrically connected via a joint bearing so that they freely rotate against each other. The housing frame of the SEA may be fixed at the joint housing body of the input link while the output mount of the spring assembly of the SEA may be concentrically coupled with the joint housing body of the output link. The rotation of the motor rotor causes the rotation of the output link with respect to the input link plus spring deflection of the spring assembly. When an external force or torque are applied between the two links, a control action of a control loop may cause a rotation and motive force of the motor that lead to the deflection of the spring assembly to balance with the external force/torque and inertial force from body masses moving together with the links.

Provided is an industrial robot in which a gear for causing a work tool to rotate can easily be retrofitted to a robot without requiring work to adjust backlash. The present invention comprises: a first wrist element that, at the distal end of a front arm of a robot, is capable of rotating about a first axis following the longitudinal direction of the front arm; a second wrist element that, at the first wrist element, is capable of rotating about a second axis intersecting the first axis in a roughly perpendicular manner; a third wrist element that, at the second wrist element, is capable of rotating about a third axis extending from the intersection point of the first and second axes in a direction roughly perpendicular to the direction in which the second axis extends; a first gear that is attached to the third wrist element coaxially with the third axis and that is capable of rotating about the third axis; a second gear that is driven by rotation of the first gear due to meshing with the first gear and that is capable of rotating; and a case secured to the second wrist element. The second gear is attached to the case via a bearing so as to be capable of rotating about a fourth axis positioned at a prescribed distance relative to the third axis.

Provided is a packing material that makes it possible to omit an exclusive part for installing a robot on a stand, and to reduce the number of parts of the robot. The packing material for packing the robot has a first support member that supports the robot in a state in which a base of the robot is exposed, and the first support member is provided with grip portions which are held by a worker to lift the robot together with the first support member.

A robot may include a main body coupled to a traveling unit, a display unit disposed above a front portion of the main body, and a battery incorporated in the main body. The traveling unit may include a wheel having a rotational axis extending in a first direction, and the battery may overlap a vertical plane that extends along the rotational axis. The vertical plane and a center of the battery may be separated by a prescribed distance in a second direction that is orthogonal to the first direction.
