For whatever illogical reason, I got interested in the idea of building a robot in the winter of 2013/2014 and first considered a full-size R2D2 (from Star Wars) - I LOVE R2S2! But, because of the cost and complexity, I decided I should start with something smaller and less expensive. Being also a fan of Wall-E and with Wall-E toys being available at a reasonable price, I decided to modify a small Wall-E toy into a radio controlled model. I picked up four Wall-E toys at a reasonable price with the intention of cannibalizing a couple of them to build the R/C version.

The first step was to dismantle one of the toys to see what I had to work with.

After determining what R/C components I would most likely need, I bought Pololu gear-motors and various servos. The gear-motors replaced the strange one-motor drive system used in the original toy to allow better speed and direction control.
