[MkMan's] LEGO spider robot combines pieces from a Mindstorm kit with a few milled plastic parts. The legs are a locomotive concept called a Klann Linkage. They operate in pairs and convert the rotational force from one motor into movement for two legs. Here, a total of four rotating gears moves eight legs, besting the hexapods we saw a couple of weeks ago in both leg count and motor economy.
Each limb is made up of five pieces plus one base for each pair. That makes eleven pieces per pair and a total of 44 for the entire robot. [MkMan] milled these parts out of 3/8″ HDPE stock. He’s made videos of forward motion and turning which we’ve embedded after the break. Even on a polished surface the bot looks fairly efficient at getting around.
