A robot includes elbows connecting forearms rotatably to upper arms with two rotational degrees of freedom. The elbow includes: an elbow joint connecting the forearm and the upper arm with two rotational degrees of freedom; an elbow drive main link; an elbow drive auxiliary link; a forearm-side main link attaching unit attached with one end of the elbow drive main link with two rotational degrees of freedom, and provided in the forearm; an elbow-drive-main-link-side auxiliary link attaching unit attached with one end of the elbow drive auxiliary link with two rotational degrees of freedom, and provided on the elbow drive main link; and two linear actuators for moving two upper-arm-side link attaching units each attached with the other end of either the elbow drive main link or the elbow drive auxiliary link with two rotational degrees of freedom, and provided so as to be movable along the upper arm.

A mechanical transmission, tethered actuation system, an autonomous ankle exoskeleton design and method of their use employing a cable, pulleys and associated pulley housings to change angular transmission of linear force on the cable. The pulleys are linked by a ground link and the cable is threaded across and between the pulleys, whereby rotation of either of the pulleys in one direction causes rotation of the other pulley in the opposite direction. Independently of the pulleys, the pulley housings can freely rotate about associated pulleys, and a link between the pulley housings is provided, whereby rotation of one of the pulley housings in one direction causes rotation of the other pulley housing at an equivalent angle in the opposite direction, thereby enabling a change in transmission angle of linear force on the cable threaded across and between the pulleys and the associated pulley housing essentially without resistance. When pulleys have the same angular velocity ratio as that of the associated pulley housings, there is no cable slack since the net changes in length of the cable wrapping around two pulleys is zero.

A driving device including a drive shaft and a first engaging member. The drive shaft rotates around a first axis. The first engaging member is disposed on the first axis to rotate integrally with the drive shaft. The power transmission mechanism includes a second engaging member, a propeller shaft, a piston, and a reduction gear. The second engaging member is disposed on the first axis engageable with/disengageable from the first engaging member. The propeller shaft is rotatable integrally with the second engaging member around the first axis. The piston reciprocates the second engaging member between a first position and a second position along a direction of the first axis. The reduction gear is joined to the other end side of the propeller shaft to decelerate the rotation of the propeller shaft. The reduction gear causes an output shaft joined to an object to rotate around a second axis.

The brake disc release device comprises: an actuating mechanism; a gear connected to a first end of the actuating mechanism; a first slider capable of sliding along a first guide piece and comprising a rack portion for engagement with the gear and a first wedge portion; a second slider capable of sliding along a second guide piece and comprising a second wedge portion for engagement with the first wedge portion of the first slider; and a pulling cable having a first end connected to the second slider and a second end connected to the brake disc.

An actuator comprising: a motor having a housing and a drive shaft, the motor arranged to rotate the drive shaft relative to the housing about a drive shaft axis; a first torque transfer device arranged to transfer torque from the drive shaft to a second shaft, the second shaft being rotatable about a second shaft axis parallel to and radially spaced from the drive shaft axis; and an output torque transfer device arranged to transfer torque from the second shaft to the housing of the motor; wherein, upon rotation of the drive shaft relative to the motor housing, the housing of the motor is arranged to rotate relative to the position of the second shaft axis.

A motor-driven articulated haptic interface arm includes: a frame; an arm linked to the frame and rotationally mobile about an axis; and a motor, which delivers at least one torque about the axis countering at least one part of forces applied to the arm by its environment. A main transmission transmits the torque to the arm and includes a capstan-type cable reducer, and an auxiliary transmission transmits the torque to the arm. The auxiliary transmission is capable of taking at least two states: an inactive state, when the forces applied to the arm by its environment are below a predetermined threshold, in which the auxiliary transmission transmits no torque to the arm; and an active state when the forces applied to the arm by its environment are higher than a predetermined threshold, in which the main transmission transmits no torque to the arm.

The present disclosure is drawn to single axis rotation systems for use with a solar device, as well as related methods and sun movement targeting devices. The single axis rotation system can include an actuator with a movable arm, a pulley system, and a rotatable shaft. The pulley system can include a base pulley, a collaborative pulley, and a compliant band about the base pulley and the collaborative pulley. The movable arm can be attached to the compliant band such that when the movable arm actuates, the compliant band causes the base pulley and the collaborative pulley to move. The rotatable shaft is attached to the base pulley and is configured to rotate when the base pulley rotates, as well as rotate a solar device along a single axis in an outward orientation with respect to the rotatable shaft.
