Robotics Monday: Exceptional NXT 2.0 Ball Color Sorter

Name of Model: A FAST NXT2.0 ball sorter

Details: Color sorters aren't exactly new, but I think we all knew that the newer version of the NXT kit (the 2.0 kits include a color sensor) would lead to more designs, some of which would inevitably improve on what we've seen before. This one, with it's zany (but somehow perfect) angles and fast linkages, may be the fastest NXT-based color sorter possible. There are some clever mechanisms here for splitting the stationary set of balls into a stream of individual balls and for changing the ways that the balls fall. The video here is pretty exceptional at really capturing the details (I'm sure we've all had enough of Technic-related videos that don't show you enough to see all of what's going on). Building instructions and code (both NXC and NXT-G) are available from the link above.
