Abstract
A device to guide an object (A) around two axes (R.sub.1 and R.sub.2). A motor (M.sub.1) controls rotation around an axis (R.sub.1) by three gears (51, 70, 71); a further motor (M.sub.2) controls the rotation of a fork joint (C) around another axis (R.sub.2) by two other gears (26, 27). It simultaneously lets run the entire first motor (M.sub.1). The gears are calculated so that the main shaft (72) of the object (A) moves around (R.sub.2), but does not then revolve around (R.sub.1).
