Exactly!

Although it could theoretically do it, the PIC in the RC isn’t exactly up for exponential equations.

What we have done every year is a lookup table... it takes more effort then writing an equation; you need to come up with a chart with 127 (or 256, depending on how you write your code) like this made up example:

int speed[] =  {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,2,2,3,3,3,3,3,3,3,3,3,3,3,3,3,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,5,5,5,5,5,6,6,6,6,6,7,8,9,10,11,12,13,14,15,17,19,21,24....

etc... i will try to find the exact code out of an old bot. the idea is that when you get the joystick value, you just take:

p1_y = speed[p1_y];

its that easy!

this also gives you a chance to tweak your robots response time and "aggressiveness"
