A parallel link robot is provided with: a base portion; a movable portion that is disposed below the base portion; a plurality of arms that link the base portion and the movable portion so as to be parallel to each other; and a wrist shaft that is supported by the movable portion so as to be rotatable about a rotation axis in a substantially vertical direction, wherein a pair of marks that indicate a relative phase between the movable portion and the wrist shaft about the rotation axis are provided on the movable portion and the wrist shaft, at positions visible from the upper side or the lateral side.

A robot fixing system includes a base member having a front surface in which an insertion hole is formed; a power transmission member configured to supply a rotational driving force to a movable part, which is supported on the base member in a rotatable manner about a first axis of rotation, by rotating about a second axis of rotation while opposing the front surface, a through hole being formed in the power transmission member to extend parallel to the second axis of rotation in a penetrating manner at a position separated from the second axis of rotation by a distance equal to a distance from the second axis of rotation to the insertion hole; and a fixing pin configured to be simultaneously inserted into the through hole and the insertion hole.

A robot includes one or more joints. At least the one joint includes: a first joint member and a second joint member disposed so as to be relatively rotatable around a predetermined axis; a reducer that relatively rotatably supports the first and second joint members around the axis on one side in a direction of the axis of the first joint member; and a bearing that supports the first and second joint members relatively rotatably around the axis and relatively movable in a direction along the axis on another side in the direction of the axis of the first joint member, the first and second joint members include respective flange surfaces perpendicular to the axis and facing each other in the direction of the axis, and each of the flange surfaces includes a screw hole or a through hole for closely adhering the flange surfaces by fastening of a bolt.

A plug-in adapter includes a thread designed to screw the plug-in adapter to an adjustment instrument, a plug-in device designed for detachably connecting the plug-in adapter to a counter plug-in device of an access opening on a robot for a reference position marking of the robot, and a stylus designed to couple a measuring tip of the adjustment instrument to the reference position marking. The plug-in device has a plug-in section that is designed for axially plugging of the plug-in section into the counter plug-in device of the robot.

Safety architecture for an automated work cell provides a barrier separating a work cell area from an operator or personnel area. The safety architecture enables personnel to conduct routine interactions with nonfunctioning motion platforms or positioning machines located in the work cell area through openings in the barrier separating the personnel area from the work cell area while other motion platforms or positioning machines in the work cell area continues to function.

A system may include a robotic manipulator with a replaceable cover material applied to rigid portions of extension of the manipulator. The system can further include a sensor or other monitoring mechanism that permits a determination of a quality of the cover material to determine whether replacement is warranted, a cover removal mechanism that permits removal of the cover material, and/or a cover application mechanism that permits a replacement for the cover material to be applied to the rigid portion.

In embodiments, a subsea manipulator tool changer comprises an ROV attachable standardized tool receiver and a tool, the subsea manipulator tool changer comprising a standardized tool latch and a standardized tool latch receiver whereby tools can be attached and detached subsea. In other embodiments, a system for changing tools while subsea comprises an ROV, a subsea manipulator tool changer, and a tool caddy configured to accept and release a tool where the tool comprises the standardized tool latch receiver.

An adapter for motor replacement includes fixing portions. The adapter has a shape of being placeable so as to be bridged between a housing that fixes a motor and a pulley that is fixed to the motor and transmits a rotary drive force via a belt and to avoid a space for removing the motor from the housing. The fixing portions are respectively fixed to the housing, to which the motor is fixed, and the pulley fixed to the motor.

A mobile robot comprises a trunk and several limbs removably linked to the trunk. Each of the limbs are configured for prepositioning the limb on the trunk, and a single flange is linked to the trunk and configured to removably fix all the limbs to the trunk. Each of the limbs comprises a motorized articulation, via which the limb is positioned and fixed onto the trunk, and can be driven in movement relative to the trunk.

A gas pressure detection device 10 detects a decrease in a pressure of gas of a gas balancer 8 of a robot 2. The gas pressure detection device 10 includes a calculating part configured to calculate a parameter Rt(?) indicating a magnitude relation between a reference pressure Pa(?) at a rotational angle ? of a rotary arm 14 and a measured pressure Pt(?) measured at the rotational angle ?, calculate a plurality of parameters Rt(?) based on a plurality of measured pressures Pt(?) at different measurement times, and calculate a moving average Rtj(?) of the parameter Rt(?) at a measurement time tj that is a j-th measurement time of the measured pressure Pt(?) (j representing a natural number of 2 or above), and a determining part configured to compare the moving average Rtj(?) with a reference value R to detect the decrease in the pressure of the gas.
