Abstract: A mobile device includes a frame with displacement means, a working arm connected to the frame including at least a first and a second articulation which are hinged to each other. The working arm is hinged to the frame, and at least a first, second and third control devices are adapted for moving the first and second articulation of the working arm and a tool, respectively, at a free end of the second articulation. A control system is adapted for controlling the first, second and third control means. The control system is adapted to drive the first, second and third control means such that the free end of the second articulation follows a predetermined upward movement along an upwardly directed path and the tool remains in a lifting position, the first, second and third control means are simultaneously controlled.

Abstract: A mobile apparatus includes a main-frame with displacing means configured to displace the mobile apparatus, a rotating sub-frame rotatably connected to the main-frame such that the sub-frame is rotatable relative to the main frame and a working arm connected to the sub-frame. The main-frame and/or the sub-frame includes a plurality of modules respectively including energy storage means configured for storing energy, energy transformation means for transforming energy to electrical energy, and power train means for driving the displacing means. The modules are connectable through any one of a high voltage, low voltage or bus control system or a combination thereof and the modules are removably mountable.
