A mechanical manipulator, which is useful inter alia as a machine tool, has a platform (6) suspended by three pairs of supportive legs (4) which are coupled to the platform at triangularly spaced-apart locations by means of three universal joints (5) each of which couples to one end of each of the two legs of a respective pair, and the two legs of each pair extend from their respective universal joint in divergent directions to spaced-apart locations in an overhead mounting (2) whereat each leg is drivingly engaged by a respective universal joint mounted electric motor (3) arranged to move the leg in its own longitudinal direction. The platform orientation and position can thus be precisely controlled by operation of the six leg drive motors. The overhead mounting (2) is domed for enhanced rigidity.
