Abstract (en)
[origin: WO2021014107A1] Autocorrecting device (1) comprising a support (2); at least two constant-diameter objects (3a, 3b, 3c) which can be rotated, at least one of the objects (3a) being said to be determinant, the other at least one object (3b, 3c) being said to be determined, each of the objects being provided with at least one stimulus (4) associated with an angular position of the object; a drive means (9) for driving the objects in rotation and having an object-driving torque M; a rotational-blocking means (6, 7) for angularly blocking a determinant object in position, a selection means (8a, 8b; 8c) for selecting an angular position of a first object with respect to a second object, the selection means applying a resistive torque Cr between said first object and said second object, said two objects having a coupled position in which the resistive torque is higher than the driving torque M and an uncoupled position in which the resistive torque is lower than the driving torque M.
