Title:
REMOTE CONTROL CAR HAVING SIMPLE SERVO CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/215347
Kind Code:
A1
Abstract:
A remote control car having a simple servo control system, comprising a car body. Driving wheels are rotatably arranged on the car body; simple coding discs (7) are arranged in a manner of synchronously rotating with the driving wheels (2A, 2B, 2C, 2D), and when the simple coding discs (7) rotate, a photoelectric receiving tube (53) is continuously switched on and switched off to form a pulse signal; motors (5A, 5B), a remote control receiving unit, and the photoelectric receiving tube (53) are electrically connected to a master control unit, separately; the remote control receiving unit receives an instruction sent by a remote controller and sends the instruction to the master control unit to convert the instruction into a desired rotating speed signal indicative of a desired rotating speed of the driving wheel; the pulse signal formed by the photoelectric receiving tube (53) is sent to the master control unit to be converted into an actual rotating speed signal indicative of an actual rotating speed of the driving wheel; the master control unit calculates a difference between the desired rotating speed signal and the actual rotating speed signal to drive the motor to increase or decrease the rotating speed, so that the actual rotating speed signal gets close to the desired rotating speed signal. The present remote control car can accurately monitor and control the rotating speed of the wheel at lower costs.
