turning with the bot
Sometimes a bad wheel configuration can cause bad turning. May I get a photo of your wheel configuration?
we are having a similar issue. we created a 1:3 gear ratio drive train. while it starts fast, turning is always slow.
moreover if the robot is stopped and then asked to turn (without moving backward or forward), it turns really slowly.
I am curious to know what do you mean by Bad wheel configurations. Can you give some examples? We make sure that the gears and wheels are not touching the plates. we use metal shafts and thin and thick spacers appropriately.
First, we need some pictures of the bot: front, back, left, right, top down.
Second, if you’ve got traction in the rear and omni up front, this creates more friction/traction in the rear… forcing the rear wheels to act as centers of rotation (a pivot), which makes the front of the bot swing to the left/right as it turns left/right. This takes a lot more power because the bot is moving as it’s rotating. This also makes for poor handling.
a factor for this might also be in your coding, if you have done your own coding there are many areas you can get turned around (I certainly do) resulting in a section of the code not working at all, but if you are using Vex’s configuration for the controller and motors it shouldn’t be a problem. Several other factors, though more unlikely, could be bent axels, too much friction, a disconnect somewhere between a wheel and the motor controlling it, or too much stress on the motors.
Vex’s turning code is very slow. Try making each side of your drivetrain go in oppisite directions
this is what I use (the wait = False lets the stops the rest of the code from waiting).
Motors burning out could be your problem. If you add motors/reduce weight, that might help.
