ABSTRACT:
The invention relates to a mechanical arm having four degrees of freedom (or possibilities of motion) and actuated by two electric motors, each motor of these alternately controls the movements corresponding to at least two degrees of freedom. The result is an arm having a mixed control for movement in series and in parallel in which the motions controlled by the same motor are carried out in different instants of time, whereas the motions controlled by different motors can be performed simultaneously.
