Computer programmer Mike Senna, known for his handmade, remote control R2D2, spent 2 years working 25 hours a week to build a working, life-size WALL-E. Because actual materials, decals, and parts from WALL-E don’t exist, the entire thing had to be built from scratch. He takes his creations out for appearances at schools, conventions, libraries, office parties, and charity events. Source Source 2
