As mentioned in my previous post, I’ve been working on-and-off for a couple years now on a reliable LEGO Technics, Crane Claws which will pick up balls reliably. To show case my ‘Ultimate Crane Grab’, I’ve built a LEGO Mindstorms NXT Coloured Ball Sorting Crane, which runs along a geared tressel, which features my Ultimate Crane Grab mechanism! The Crane picks up coloured Ping-Pong Balls, and drops them into cells according to their colour.
