I have attempt to design the bot in a modular way, so I have split drive system into two, i have two rage bridge controllers each controllers two motors and they have separate lipo power sources, this is also the same for the weapon system which is another controller, motor and lipo. The idea was that if one part of the system is damaged or faulty the others would continue to operate independently.

But how does this work with removable links, would i need to have 3 of them? or was this a bad idea?

Thanks.
