One thing I am interested in is building and designing a robot or a electrically driven mechanism that can sort the different sizes of bricks from each other. Sound simple? Not really, if you want to dump unsorted bricks into a hopper and then have them feed to something that does the measuring and sorting of them. It probably would be good if I can get some rotation sensors, and figure out a way for the sorting mechanism to determine brick size, but the big problem I have at the moment is coming up with an input hopper assembly that can't get jammed up. The PnP robot Mark Bellis mentioned in his post is intriguing, but the bricks are already aligned and stacked. What I want is to advance to the next step, IE make a robot - or a feeder to a robot - that can do that all by itself. Ideally, it should even be able to handle bricks that have been snapped together, but that would probably be beyond the capabilities of LEGO grip power to pull apart. It might be able to pull apart loosely gripping bricks - I'm not sure, but I'm pretty certain it wouldn't be able to disassemble bricks firmly stacked together without some help. Cheers ...

G'Day How about starting with something simpler? Say use the blocks from our block stacking events? Right of the top you would have large and small, black and white, giving four different items to sort, (more colours can be added later.) The (...)
