An articulating robotic arm for minimally invasive surgery, comprising a proximal arm segment extending along a longitudinal axis of the robotic arm and a distal arm segment connected to the proximal arm segment, pivotable about a pivot axis orthogonal to the longitudinal axis. The distal arm segment comprises a pinion segment formed with pinion teeth arranged about the pivot axis in the form of a pinion. A rack element is arranged on the proximal arm segment such that the rack element is movable in the longitudinal direction of the rack element parallel to the longitudinal axis by means of a translation, and rack teeth formed on the rack element are engaged with the pinion teeth so that a movement of the rack element in the longitudinal direction via the rack teeth and the pinion teeth is converted into a rotational movement of the distal arm segment about the pivot axis, and so that the distal arm segment pivots relative to the proximal arm segment about the pivot axis.

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.

An orthopedic device for supporting a lower limb and/or a lower back of a user includes at least one upper joint element, at least one lower joint element which can be pivoted relative to the upper joint element, and at least one actuator configured to apply a torque to the upper joint element and/or the lower joint element. Application of a torque pivots the upper joint element and the lower joint element relative to each other. The orthopedic device also includes at least one ground contact element which is connected to the lower joint element such that when the orthopedicdevice is in the mounted state, the torque applied by the at least one passive actuator is transmitted by the ground contact element to a ground on which the user is located.
