Re: Banebots RS-775 Case Short

Quote:
Has anyone tried monitoring the voltage on the case live while the robot is in action?

I am thinking that I could have put connect the case to a resistor network. For example, I could put two relatively high resistors in series between the battery and ground and tie the case to the middle of these and monitor this voltage. This monitor voltage (i.e. the case) would sit at roughly 6-8V (1/2 battery) unless a short starts and then it would start going rail to rail 12V - gnd - 12V - gnd - ...

And this is when I would replace that motor.

What do people think of this scheme?
Why worry about it when the robot is in action? You can't stop the game and do anything about it anyway.

Monitor the resistance between matches, change them out if it reaches a value bothers you.
