Meccano Meccanoid G15
Meccano Meccanoid G15 was a 4-foot tall buildable humanoid robot — assembled from 635 Meccano parts into a life-size personal robot that could walk, talk, and be programmed through LIM (Learned Intelligent Movement) by physically guiding its arms through motions it would then repeat. Voice commands via a mobile app could trigger stories, jokes, and programmed sequences. Discontinued but notable as one of the most ambitious consumer-priced buildable humanoid robots ever released. Available on secondary markets.
