Wall-E Prototype was the first robot I ever built inspired of course from the fantastic movie Wall-E which was on of my inspirations for becoming a robotics engineer. The robot had two wheel, four AA batteries, an IR sensor and an AXEPAD microcontroller. This was before Arduino and Raspberry Pi became popular in hobby robotics.
Wall-E prototype was capable of obstacle avoidance. It had remarkably high success rate for such a simple robot. As much as I should update the original post on Let's Make Robots for innumerable English errors, it was my very post post on a public forum, with my naiveness, joy and curiousity in all its glory, so I will leave it be. It was the first time I experienced giving 'life' to an inanimate object, and the aspiration to do this as a career thus began.
