Motor Scaling

I have 2 DC Motors controlling an arm,but they are too powerful, how do I decrease the amount of power they use without having to focus on how much I move the analog stick?

Thank You!!~

Re: Motor Scaling

You could clip or scale the values. Clipping is the easiest. I have a function in my Driver Suite called clip:


	Code: #define min2(a, b) (a < b ? a : b) #define max2(a, b) (a > b ? a : b) #define clip(a, b, c) min2(c, max2(b, a))

To find out how to scale values, I would say: "Use the Omniscient Google."

Re: Motor Scaling

Alternative, you can just scale down the motor power. For example,


	Code: motor[motorA] = joystick.joy1_y1/3;

That doesn't seem to effect the speed of the robot. But, I will try clipping.
