In the figure is the PWM generating circuit of the two chassises drive motor controlled by the linear circuit of game controller or the model airplane racker. J1 is the outlet of the racker, 123 and 456 are the potentiometer of the x and y dimension. U1B provide with the half power supply voltage, U1A is the voltage follower. The x and y become the voltage signal which controls the rotating speed of the left and right wheel after being compounded. While in use, we make L=(x+1)y/(x+1.4), R=(x-1)y/(x-0.6), and the effect proves to be good after the practice.
