This report deals with the development of new control vehicles for the bedridden, physically handicapped person who needs a help-system for carrying things to the bedside from the stock in the room. This new control method is characterized by a unit loop system on the drive track. This unit loop system was constructed to execute three actions: stop, backward and right forward movement, under the control of a on-board microcomputer.
This control method is used in small rooms. It also enables one to increase the driving area of a vehicle without reprogramming and adjusting the control mechanism.
