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.
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.
