Meccano Based CUBLI

Maybe this is the world's first Meccano-based CUBLI? One of the challenges is to use as few parts as possible since the parts are made of metal which is heavy (heavier compared with the Lego Technic version: https://youtu.be/80Q93yVHv6M). The benefit of using Meccano is they are sturdier (partly because of fixing multiple parts with bolts and nuts). The original motors provided by Meccano have not enough torque for CUBLI.
