    • A system and method for sensing and compensating for unintended joint movement of a robotic arm caused by application of a load. The system may have a plurality of external encoders each in intimate contact with an external edge portion of one of a plurality of robotic arm joints to sense joint movement caused by application of the load, and a computing device configured for calculating a compensation amount based on the sensed joint movement and sending the calculated compensation amount to a corresponding robot motor encoder to correct the position of the joint by the compensation amount. The method may comprise applying the load one portion at a time, such that a portion of the load is applied, the compensation amount is calculated, the position of the joint is corrected, and then the process repeats, with another portion of the load applied to the robotic arm.

    • The device can control an electric motor intended to rotate the drive shaft of a movable member, solar protection member, closure member or the like.The control device comprises a pulse generator device and an angular position coder, governed as regards rotation by the drive shaft, provided for supplying a signal permanently to a logic processing unit connected, through the intermediary of an input-output interface, to the terminals of the pulse generator device and of the coder and, through the intermediary of an output interface, to the electric motor. The means for regulating the stopping positions are constituted by switches connected, through the intermediary of an input interface, to the logic processing unit, in order to memorize the desired angular stopping positions in the working memory of the latter. A non-volatile memory is connected to the logic processing unit for safeguarding these angular positions in the case of a cut in the power supply. The logic processing unit is provided on the one hand for permanently analyzing the signal supplied by the generator device and by the coder, calculating the angular position of the drive shaft and comparing it with the desired angular stopping positions, and on the other hand for interrupting the rotation of the motor as soon as the calculated position and the desired stopping position are identical.
