The paper presented the driving mechanism structure of unmanned ground vehicle. The most fundamental feature of mobile platform has the transformable crawler. The crawler system transforms the shape of the track based on a driving mechanism. By adopting a double shaft structure to simply the crawler system was UGV platform. A automatic transmission is built to increase driving torque of unmanned ground vehicle. Available driving modes include a speed mode to drive at top speed on flat surfaces and a torque mode to handle uneven terrain, obstacles and stairs. The double shaft Also UGV platform was tested on uneven surfaces including muddy, sandy, and gravelly terrain. The UGV platform has shown good results in the driving test.
