Abstract: A device for generating a defined position and orientation of at least one platform includes rod elements arranged in at least one four-bar linkage. The at least one four-bar linkage is pivotably connected to the platform. The angular position of the at least one four-bar linkage is motorically adjustable for changing an orientation of the platform.

Abstract: A device for moving a rod body in a space includes a frame and connecting arms connected to the frame and having at least two degrees of freedom. The rod body is pivotably connected to the connecting arms. At least one drive is connected to each one of the connecting arms for controlling an active degree of freedom. The rod body has a first end point and a second end point. The first end point defines a spatial position within the space. The first and second end points together define the orientation of the rod body in the space. The connecting arms serve to control the first and second end points.

Abstract: A drive for inducing pivoting rotational and linear movements includes a drive unit comprising two coaxial motors and having a pivot axis and a rotation axis normal to the pivot axis, and a drive element formed as a linear drive. The drive unit operated to induce swinging movements about the pivot axis and rotational movements about the rotation axis is interchangeably and releasably connectable to the linear drive. A transmission device interconnects the drive unit with the linear drive.

Abstract: Articulated drive, more particularly for industrial robots, having two axles kinematically independent of, and especially perpendicular to, one another, the axle movements being coupled with both rotary movements of the motors by means of a differential gear, wherein, in order to obtain a compact drive, the drives are arranged concentrically with one another as well as with both driving gear members of the differential gear.
