Re: Smaller Cheaper Robots
ROFL!! I'll use Solder over anything out there now. theres always a mechanical way to make things. Like the "night rider" LED thing i made for my team's robot. It was pretty much a servo which turned a metal arm which came into contact with metal pins which completed a circuit, and then turned on a certain LED. No relays or circuit boards necessary.
