摘要

The device has a control case (1) with four rotating discs controlled by a bar. Three discs (2,3,5) are integrally coupled to front and rear driving assemblies. The fourth disc is a sprocket that de-limits the front and rear driving assemblies. The fourth disc causes the driving assemblies to rotate in different directions to turn the device or in same directions to give a skewing movement to the device.
