5 Lego Walkers vs. 7 Obstacles

How many legs must a robot have to navigate over various obstacles in the terrain? Or does it really matter? Maybe the type of feet matter more than the number of legs. Or maybe the size of those feet are key. The Brick Experiment Channel built five different types of walking machines out of LEGO blocks and pieces, and then subjected each of them to seven different obstacles to see which design worked best. None of them had an easy time. Well, one did, but I won't tell you because this is a competition on video, and you may get really invested in your favorite walker robot. I will go as far as to express sympathy for the "simple 2-legged walker" because that little guy has no talent for walking whatsoever and no clue going into an obstacle. Yes, it's okay to laugh at a machine that doesn't work properly. (via Metafilter)
