Title: Controller for omnidirectional mobile vehicle
Inventor: YAMAMOTO YUZO
IPC: B62D11/04
Filed: 1990-08-29
Abstract: PURPOSE:To travel a vehicle without changing the posture angle of the angular velocity of a vehicle main body under a various kinds of travel modes and travel conditions by detecting the speed of a pair of driving means, respectively, and controlling the angular velocity of the vehicle main body by controlling a rotary driving means based on computed speed difference. CONSTITUTION:When an omnidirectional mobile vehicle comprised of a chassis carriage providing with driving wheels and the vehicle main body mounted on the chassis carriage rotatably freely is changing a progressive direction, the speed difference occurs in a pair of driving wheels, and the value of the speed difference is varied according to the speed of both driving wheels. At this time, a signal in accordance with the angular velocity of a chassis member is found by finding the speed difference signal of signals from the speed detecting means 8a, 8b of both driving wheels by a speed difference detecting means 20. Furthermore, a signal in which the polarity of the signal is inverted by a polarity inversion means 21 i.e. the signal with the same angular velocity as and with direction opposite to that of the chassis member is inputted to a speed servo amplifier 22 as command speed, which comprises a speed servo loop. In such a way, no posture angle of the vehicle main body is changed even when the vehicle travels in any direction at any speed, which enables the vehicle to travel in all directions.

IPC: H04J3/24
Filed: 1987-09-10
Abstract: PURPOSE:To simplify a hardware and to decrease a cost by using a dual port RAM as assigning table part. CONSTITUTION:For an assigning table part, a dual port RAM 20 is used, one side port of the dual port RAM 20 can access the writing and reading from a control part 4 to execute the re-writing and reading of the contents of an assigning table and other side is set so as to be able to execute only the reading.
