Abstract A device for determining, in at least three spatial directions, a force acting on a body includes at least one sensor element for attaching to the surface of the body, which element includes at least three individual sensor elements, each individual sensor element being designed to determine an individual force in one direction, or which includes at least one individual sensor element which is used to determine an individual force in three spatial directions, and an evaluation/control unit which records the individual force determined by each individual sensor element and is designed to calculate the force acting on the sensor element in at least three spatial directions by projecting the individual forces onto a virtual point of the sensor element. A method for determining a force acting on a body in at least three spatial directions and a method for controlling the movement of a body is disclosed.

Abstract A gear arrangement (14, 14a) suitable for use in an articulated robot arm is configured with a drive body (16, 16a) with at least one drive-side drum (20, 22) arranged rotatably about a drive axis (18, 18a), and a drive output body (24, 24a) with at least one output-side drum (28, 30) arranged rotatably about a drive output axis (26, 26a). At least one cable (32, 38) is provided, and can be wound on the at least one drive-side drum (20, 22) as well as on the at least one output-side drum (28, 30), and has a drive-side cable end (34, 40) as well as an output-side cable end (36, 42). The drive-side cable end (34, 40) is arranged on the at least one drive-side drum (20, 22) and the output-side cable end (36, 42) is arranged on the at least one output-side drum (28, 30).

Abstract A device for measuring a change in length has a first fastening element, a second fastening element and at least one length element which is arranged between the two fastening elements. The one length element has a first end a second end and a length along a longitudinal direction. A force acting parallel to the longitudinal direction leads to a change in length of the length element. A lever element has a first end, a second end, and a fulcrum and is arranged transversely to the longitudinal direction. The lever element includes a first lever arm with a first length between the fulcrum and a first lever arm end and a second lever arm with a second length between the fulcrum and a second lever arm end, with the second length being greater than the first length.

Abstract A device for determines the torque and/or the rotary angle between a first shaft and a second shaft, which are coupled via a gear mechanism to rotate relative to one another about an axis of rotation. The first shaft has a first end region, a second end region, and a first direction vector pointing in parallel with the axis of rotation from the first end region to the second end region, and the second shaft has a first end region, a second end region, and a second direction vector pointing in parallel with the axis of rotation from the first end region to the second end region. The first shaft is designed as a hollow shaft and the second shaft is arranged coaxially in the first shaft in such a way that the first direction vector and the second direction vector have the same orientation.
