Our robot has two chains, each nearly six foot tall--pretty hard to find timing belts that long.

But that adds up to like 23 feet of chain. Heavy.

I know little about plastic chains, but if you're using #35 chain, you can switch to #25. Or even bicycle chain. Or lose the weight elsewhere. Switch to mini-cims. Canburgulars are very valuable and will make people want you.

We designed one that weighed in at about 4 lbs.

I think you can find four pounds.
