With a newly designed torso and reinforced framing, 'Stick' is a far better robot than walker II.
Walker II (on the left) looks nearly identical to walker IV (on the right)
Taking the legs from Walker II and rebuilding a new torso for them paid off this time. I used AAA battery holder instead of AA and filtered the power. The best improvement was the IMX Inverter Multiplexor that I free-formed. It minimized the dual in-outs and allows for prototyping the timers and the Bypass Turn-Boosters. With the shape and design of the legs Stick is a fast robot. The downside is that Stick cannot climb over obstacles higher than 1/2 inch. Also it tends to get stuck in holes and cracks. Stick is still a huge improvement over WLKR II. It displays great characteristics and seems a very buglike-lifelike creature.
Stick's best new improvement is this free-formed IMX Inverter.
Stick was much more fun to build than its forerunner, and better built too.
