WTC - Wild Thumper Controller - Calibratting VR1 and VR2

Hi, I'm working on a HTTP controlled robot ( http://www.youtube.com/watch?v=5xNUsHhzaBU ), but I have a question about Wild Thumper Controller.

Lets say, for example, I don't want use "current sensor", and i simply set up Leftmaxamps and Rightmaxamps to a number that motors never reach or strip out the protection code from my project. May the position of VR1 and VR2 clog or put down the performance or de current delivery?

They simply adjust the gain on the amplifiers used to measure the voltage drop across the fuses.

Thanks guys.

What about VR1 and VR2 calibration, let's say I removed the protection code, If VR1 and VR2 are miscalibration, that will affect the robot performance?

Or VR1 and VR2 are used only to measure(not to deliver) current?


Just asking, I don't really want remove the protection, just curious about these tunners and how it affect the system.

I agree with Chris, you are better off using the current sensor.

It should be noted that the fuses have a very small amount of resistance which is used as a current shunt. Because the resistance is so small they really need to be soldered into the holders otherwise you cannot get accurate readings.

If you calibrate the sensors then they can shut down the motors before the "slow blow" fuses blow so you should never need to replace a fuse. If you do need to replace a fuse then they are not hard to desolder.

Yes, you can simply remove the current monitoring stuff from the code and well, it won't be excecuted. I have to ask why though...

You have a wild thumper chassis there, complete with 6 high-current motors. I can't see any reason to remove this safety feature.

Is it just the fact that you don't want to bother with the calibration stuff?
