Big Al, you know whereof you speak. Those who participated in Stack Attack (FRC 2003) may recall that many robots had problems with overheating 40A breakers when they climbed the ramp. This was often accompanied by a buzzing noise coming from the breakers. Breakers that saw this type of overloading eventually degraded and would no longer sustain high (>50A) peak currents; this caused some robots to veer off intended course when the problem was more severe on one side. Extra 40A breakers were a very popular bartering item in the pits that year.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
