It is applied widely in the flexible manufacturing system and the automated factory, and has the merits of high transportation efficiency, energy conservation, the operation reliable and the flexible transportation. It can enormously increase production automation levels and production efficiency. Based on analyzing present situation and development of feeding equipment at home and abroad, two wheels of independent drive are designed. The design process of the car includes: mechanical structure design according to the design requirements, choosing direct current motors based on the speed of the car, then making the worm drive design according to the speed of the motors and car, then to design the axis structure and choose the bearings based on the load and speed of the car, at last making the control system of the microprocessors design according to driving request of the car. This car can realize independence functions of forward recession and turning through the microprocessor controlling speed and steering of the direct current servo motors .It will drive along specific route. The advantages of design scheme: small in size, great load capacity, smooth driving, small errors of transmission, high maneuverability and convenient operation.
