Received the following from Brazil - Ivan Seidel has shared a video with a robot that appears to be using a single motor for color sorting... you can view more on his blog here (but it's in Portuguese).
Thanks for sharing, Ivan!
Update: I posted the wrong video earlier and incorrectly placed Ivan in Portugal... he is from Brazil.
