Hello guys,
We have built a micromouse as a project at university.
The problem is that when is runs in the maze and someone touches on any metallic part of it, the microcontroller resets.
The maze floor is made of plastic (I think it is PVC) and the wheels of the micromouse are aluminium with rubber around them.
The chassis is aluminium but it is not connected to the circuit signal ground.
It is powered by a LiPo battery.
I believe that the problem is static electricity. As the mouse moves around charge builds up on the chassis due to the friction of the rubber of the wheels and the plastic floor. When someone touches a metallic part, it discharges quickly to earth and the current pulse resets the microcontroller. I connected the chassis to earth via a wire and the problem was solved.
Any ideas of what is going on?
Thank you.
