Here is another 100% mechanical "obstacle-avoiding rover". Like my previous
attempt at: http://news.lugnet.com/technic/?n=14957
it has only one motor and no electronics. This one is based on a simpler
principle. The left and right sides operate independently - on each side the
wheel changes direction whenever the bumper on that side is pushed. When it
runs into a wall at an angle, it first rotates until the second bumper hits the
wall, and then reverses away. The net result is a "reflection" off the wall
(this is much easier to understand from the video!).
