Land based tracked robot can easily cross over larger obstacles due to their greater area of ground contact and can be used on almost any terrain. Land based tracked mobile robot is used skid steer drive as a mechanism to moving. Skid steer is related to the differential drive system. The tracks is attached on the two side of the mobile robot chassis and driven by two separate motor. It is steered by moving those tracks at different speeds in the same or opposite direction.
