Toolbox has always been pretty stately. Kinda slow. I forgot I set the motor controllers to ~30%....
Since he's apart and I was thinking of using our Pololu 18V, I went ahead and started that. To keep the 12V motors cool enough I had to adjust the PWM to not exceed 12V average. So I had to reprogram the controller.... and it was at 1000/3200
Now I've moved it to 2020. (Batteries can be higher than 18V, so I did 3200*(12/19) instead of 12/18). Now he's running at 64% instead of ~30%. And the voltage has jumped by 50%.
He's much peppier now.
Haven't stuck the top back on, but the bottom can turn on carpet. On the wood floor it's hard to avoid spinning in circles. I'm guessing the top will make him a little more controllable. Otherwise, I'll have to adjust the mixing on the controller.
Hoping to get him to Celebration. Hopefully we won't have lego flying off the treads everywhere with his new speed!
