PURPOSE:To obtain an optimum route with a small processing quantity by designating two spots on a moving route network, successively increasing to an accumulating total moving stroke from a first spot, pursueing respective moving routes and selecting the route to reach a second spot first. CONSTITUTION:A driver 2a shows a map, present spot, etc., on a CRT 2b with the instruction of a CPU. The map is recorded in a CD-ROM and read by controlling a driver 3b through a I/O. A direction key and others are equipped with a keyboard 4. Pulse generators 5b and 6b are provided at the driving shaft of right and left wheels and counting is executed by counters 5a and 6a. A voice synthesizing unit 7a generates a prescribed message with the instruction of the CPU and a voice unit 8a detects the guide information of a mike input voice. By successively extending the circle of the center and pursuing the moving route with a present position, the processing quantity is decreased, and by using the position information and mutual connection information of a branching point, an optimum route is further obtained by a small processing quantity. |
