Chris Dugan's Course Project The robot that I built is not
necessarily modeled after a specific animal. It evolved from the
simple goal of getting a robot to walk on four legs. Having very
little robotics experience and even less engineering experience,
this was no trivial task. Below, you will find the design ideas,
the actual robot, and the CAD modeling of the robot. My robot
was built using Legos from the Lego Mindstorm kit. This kit is
basically Legos with a bunch of motors and similar gadgets.
Handyboards are also provided that are "fully" programmable. The
only necessary programming involves turning the motors on. This
is arguably unnecessary due to the ability to use a 9V battery,
but I digress. I began by attempting to build something usable
out of the Legos. I decided to use two motors facing opposite
directions. One motor would power the front two legs and one
motor would power the back two legs. In order to balance the
creature, the diagonal legs would be in step. The feet were
block shaped and rig
