Those are genius! I knew mcmaster must have had a part to make it easy to interface with motors. They have everything its just a matter of finding it in their massive tomb(or website now i suppose.) I'm going to tell my team to order a bunch of those right away. Sersiously just about the biggest issue my team has is interfacing with motors, its a big challenge converting output shafts into something a sprocket or pulley can attach to well. Especially in the robotics class that has been started in my school, they end up doing all sorts of silly things to mount sprockets. Every team should be told about them.
Okay i've definitely been involved in FIRST too long. I just got excited about a nifty little collar thing.
