Project 2Dof

I think he's got the camera mounted on the rig. If so I'd move it somewhere else, won't regret it

@Nick Moxley and @Blame73 I will improve my motor supports and my camera support.
when i sit in the seat my weight try to move the motors to down and the motor wants back to "middle" so alltime the motors are shaking? Do you have any ideia to improve this?

Yes. You didn't correctly positioned the seat , so the COG is incorrect.
When you sit, even with motors off, the seat shouldn't move at all. Solution: reposition your seat accordingly.
Once fixed you'd even be surprised from what even wipers motors could do

Imo you dont want a 100% perfectly balanced seat. you want a Slight amount of weight to be sitting on the motor's to avoid that "sloppy zone in the middle"....i would say in the 5-10% range would be ample.

I moved a little bit the middle to up, and changed my eletronic circuit in the begin i was using the eletronic circuit from the fatuba motors, i was taking the signal and sending to H bridge, i'm think that because i changed the potenciometer of the fatuba circuit maybe it showed some interference. So i used the arduino code of the @RacingMat and used the circuit 7808 (AND port) to make the logic to move the motors, soon i post the video.

@Blame73 and @Nick Moxley Thanks for the tips.

After few days working hard, i made it work the simtool + step motor.

I will build the next axis and adjust the gears, motor speed and torque D
