Balancing robot for dummies

Hi Kas,

compliments for your great job and info.

I have terminated a self balancing robot very similar to your (same IMU), except for motors.

I used 6V HITEC HS-325HB hacked to run continuosly, but this motors are not enough for he job they have to do.

I tried to make the robot less high but it became too instable..

anyway I order the same Your Pololu equipment...waiting for shipment.

Two questions:

(1) in the setup, with the function calibrateSensors(); you have to put the robot (each time you switch it on) exactly in the static equilibrium position in order to evaluate zero values (exept for z).

is this a little bit boring and could produce errors (if it is not perfectly perpendicular)?

If during the calibrateSensors() i'll give a tilt, the Robot will work to keep the tilt!

maybe there is something that I cannot understand?

(2) what do You use to recharge the 12V batteries?

thanks,

bye,

Prof
