A system and method for monitoring belt wear or tread wear of a tire includes at least one radio frequency identification (RFID) tag with unique identification embedded in the belt or tread of the tire at one or more wear points. An RF tag reader periodically monitoring signals from the at least one RFID tag. If the RF tag reader fails to obtain any signals from the at least one RFID tag, indicating a destroyed RFID tag, the user can be warned about a wear problem of that belt or tire. RFID tags can be distributed at different depths of the tire(s), or across the tread at the same depth, of the tire(s) to determine different wear problems. The same RFID tag can also be used for inventory tracking purposes.

There are two basic methods of steering a wheeled vehicle. One method is to turn one or more steerable wheels. The other is to drive one or more left hand wheels independently of one or more right hand wheels. Traditional vehicles address the potential conflict between to two steering systems by either disabling one system or by causing one to overpower the other. This leads to skidding or scuffing problems respectively. In the present invention both steering systems are enabled but are integrated by means of an on board computer so that they always act in unison. This mutual reinforcement will allow the invention to operate safely on steep or slippery slopes while minimising fuel consumption and ground damage. The invention will also be more manoeuvrable than traditional vehicles since it is capable of both pure rotation and pure translation or any combination of rotation and translation.
