lThe most unique type of Locomotion system
lIt is composed of a four wheeled chassis and a platform that can be raised or lowered

lThe wheels are driven by a motor for translation motion in a straight line
lFor rotation one motor is needed to lower/raise the platform & another to rotate the chassis around the platform
lThis system can guarantee perfect straight line motion as well as accurate in – place turns to a desired heading

lThe system is quite complex in design
lA still more complex design uses only two motors. The wheels and the platform rotation are coupled to a single motor. When in translation the platform has no effect as it is above ground. And when turning, the wheels are off the ground due to the lowered platform
lThe machine is restricted to only in – place turns. This may be an hindrance in some cases
