1. A mobile robot comprising:
- a platform;
a pair of track wheel driving modules attached to opposing sides of the platform, each of the track wheel driving modules having;
a track assembly;
a wheel assembly;
a pair of a swing arm mechanisms each operably pivotally attached to the platform, each swing arm mechanism having a swing arm, a front wheel operably attached to the swing arm and a front roller operably attached to a distal end of the swing arm and an arm drive motor operably connected to each swing arm and the arm drive motor drives and controls the angle between the platform and the swing arm, and each swing arm having a wheel position and a track position; and
wherein each of the track wheel driving modules is moveable from a track position to a wheel position and wherein in the wheel position the pair of swing arm mechanisms are pivotally used for independent steering of the mobile robot and in the track position the swing arm acts like a flipper.
