Details: This may be the most useful LEGO robot we've seen yet. This machine can sort LEGO pieces by shape and weight. As you can see in the video, a handful of pieces are pushed out of a reservoir of LEGO elements, and a pair of conveyor belts move the parts from there to a digital scale. The digital scale is in view of a webcam, along with the piece on it. OpenCV is used along with some custom software and a custom database of parts to identify the pieces. From there, another mechanism puts it into one of eight cups based on what type of piece it is. According to the blog posts describing this, this is just the first iteration. I can't wait to see where this project ends up.

Housekeeping note: in the interest of not letting things get out of hand, we will not be taking the time to make up the week we just accidentally skipped. We apologize for the inconvenience.
