One first drive unit that advances or recedes in the X-direction and that exerts a drive force in the X-direction to a movable table is arranged to exert a drive force to a center position in the Y-direction of one end part in the X-direction of the movable table. Two second drive units that advance or recede in the Y-direction that is perpendicular to the X-direction, and that exert the drive forces in the Y-direction to the movable table are arranged to be point-symmetric with respect to the center of the movable table as the center of symmetry. Plural plane guide bearings are arranged at positions such that the total sum of the moment forces of the respective plane guide bearings is zero on the center axis line in the X-direction of the movable table.

A robotic arm of an industrial robot includes successive links connected by joints having respective drives and associated transmissions for moving the links. First and second links have respective first and second housings that transfer forces and moments arising from the weight of the robotic arm, or a load carried by the arm, to adjacent links. A first drive rotatably connecting the first and second links includes a drive housing, a rotor, and a stator connected to the drive housing. The drive housing is fastened to the first housing of the first link and forms an external wall of the robotic arm. The transmission associated with the first drive includes an input link that is joined with the rotor of the first drive. An output of the first drive is connected to a flange that is fastened to the second housing and rotatable relative to the drive housing.

A mechanism for a winch assembly includes a link assembly and a bracket. The link assembly includes an actuator having an end configured to be coupled to a winch free spool device, a bushing coupled to the actuator, and a projection extending from the bushing. The bracket defines an aperture that receives the actuator, and the aperture includes a lower portion and an upper portion. The lower portion of the aperture is sized to receive the bushing therethrough and the upper portion of the aperture is sized to engage the projection such that the winch free spool device is selectively locked in an engaged position.

A robotic snake comprising a plurality of friction anchors, a plurality of segments and a plurality of servo motors are disclosed. Each of the plurality of segments includes a first link and a second link connected at a first joint, a third link connected to the first link at a second joint, a fourth link connected to the second link at a third joint, a fifth link connected to the third link at a fourth joint. The simultaneous rotation of third link and fourth link of each of the plurality of segments results in a translational movement and/or a rotational movement. A plurality of servo motors is configured to rotate plurality of joints. The fifth link of one segment and first link of next segment of the each of the plurality of segments act as a quaternary link serially connects each of the plurality of segments.

A knob structure includes a base support, a knob portion, a seat and a plurality of elastic pieces. The knob portion has an inner wall surface. The inner wall surface is inclined to an axis and surrounds the axis to define a space. The knob portion is signally connected to a processor and configured to rotate relative to the base support about the axis. The seat is at least partially located in the space. The seat is at least partially sleeved to the base support and configured to move relative to the base support along the axis. The elastic pieces are disposed on the seat and configured to abut against the inner wall surface.

An apparatus may, for example, include a first lever pivoting about a first axis. The apparatus may also include a second lever mounted with the first lever, pivoting about a second axis, and biased to a first position. The first lever can be configured to engage a braking system of a vehicle when the first lever is pivoted about the first axis and the second lever is in the first position. The second lever can be configured to be pivoted about the second axis to a second position. The first lever can be configured to disengage a reverse lockout system of the vehicle when the second lever is in the second position. The second lever can be configured to be pivoted about the second axis to a third position, which cases the first lever to engage a parking brake mechanism of the vehicle.
