Described is an apparatus for robot-aided grinding, comprising the following: a manipulator, a linear actuator, and a grinding machine which includes a rotating grinding tool and is connected to the manipulator via the linear actuator. The apparatus further comprises a protective cover that partially surrounds the rotating grinding tool, the rotating grinding tool protruding from the protective cover at least on a first side. An adjusting mechanism is provided which connects the protective cover to the grinding machine and is designed to adjust the position of the protective cover in relation to the grinding machine.

A robot includes a first link, a driving device configured to cause the first link to rotate, a transmission member configured to transmit a rotation of the driving device, a first stopper provided on the first link, and a second stopper provided on the transmission member, wherein the first stopper and the second stopper are brought into contact with each other by a relative movement between the first link and the transmission member.

A radiolucent circumduction joint that has one, two, or three degrees of axis move movement about a central point that is able to mirror human joint movement.

An arm revolving-type robot includes a first member, and a second member coupled to the first member so as to be relatively rotatable, at least one of the first member and the second member including an arm portion. The second member includes a member main body portion, a protrusion that is provided on the member main body portion so as to protrude outward from a wall surface of the member main body portion, and that abuts on the first member along with rotation of the second member to regulate a rotation range of the second member, and a shaft-shaped reinforcing member disposed inside the protrusion. The protrusion and a remaining portion of the member main body portion are integrally formed of the same material, and the reinforcing member is disposed from the protrusion to the remaining portion of the member main body portion.

The apparatus and method described herein allows for the automated replacement of end effectors on a robot without requiring external power source such as electricity or compressed air. The programmed robot motion provides the mechanism for tool changing. This simplified approach provides a simpler, less expensive solution to systems currently provided. The robot motion provides the mechanism and all the power needed to enable the tool changing.

A leg assembly for a legged robot includes first through three motors, first through second legs, and a transmission component. The first motor is coupled to the second motor to drive the second motor to rotate, and a rotation axis of the first motor is substantially orthogonal to a rotation axis of the second motor. The second motor is coupled to the third motor to drive the third motor to rotate, and a rotation axis of the third motor substantially coincides with the rotation axis of the second motor. The third motor is arranged at a first end of the first leg, the second leg is pivotably coupled to a second end of the first leg, and the transmission component is coupled to an output shaft of the third motor and the second leg to drive the second leg to rotate relative to the first leg.

A surgical system includes a motor, a first link movable by operation of the motor, a plurality of non-driven, revolute joints coupled to the first link such that the first link separates the plurality of revolute joints from the motor, and an end effector coupled to the first link via the plurality of non-driven, revolute joints.

A robot is provided which includes a hub; an elbow joint; a wrist assembly; a first upper arm which is rotatably attached on a first end thereof to the hub, and which is attached on a second end thereof to the elbow joint; a first lower arm which is attached on a first end thereof to the elbow joint, and which is attached on a second end thereof to the wrist assembly; and a hard stop which extends over the elbow joint and a portion of the lower arm. The hard stop prevents the wrist assembly from contacting the hub when the motor of the robot is not engaged.

A surgical system includes a motor, a first link movable by operation of the motor, a plurality of non-driven, revolute joints coupled to the first link such that the first link separates the plurality of revolute joints from the motor, and an end effector coupled to the first link via the plurality of non-driven, revolute joints.

A Z slider includes a rotating shaft capable of at least one revolution centered on a rotation axis, in a state Where the rotating shaft supports a measurement head that is connected to a plurality of cables; a θ axis drive motor that causes the rotating shaft, to perform normal rotation in a clockwise direction and reverse rotation in a counterclockwise direction; and an oscillating link that oscillates in a state of contact with the rotating shaft when the rotating shaft is performing normal rotation in the clockwise direction and limits normal rotation in the clockwise direction that is equal to or greater than a predetermined angle, and that oscillates in a state of contact with the rotating shaft when the rotating shaft is performing reverse rotation in the counterclockwise direction and limits reverse rotation in the counterclockwise direction that is equal to or greater than a predetermined angle.
