Welcome to John's R & D lab currently working on project Vorknx. Unlike in the game Tie fighter, this project is not about making cloaked corvettes. It is about creating functional biomechanical movements with as little LEGO parts as possible. I use the Robotics Invention system V1.5 and Droid Developer Kit. I currently have a quadrapedal that has the capability of moving forward and backwards at a medium rate. Here are pictures of what it currently looks like.

2nd movie is 14 seconds long and 2.57MB
All righty, it's been many years since the time I made that AT-AT from scrounging parts. Now I'm on to more technical, more advanced robotics. I currently have a BASIC STAMP 2SX, 2 motor controllers (I forgot their chip number), 2X 3Volt Geared motors, and 2 stepper motors. Vorknx will be made out of wood construction (square dowels), and be a full 3 joint/leg walker hopefully. That's the goal for the end of the month. The stepper motors are to actually change the direction of the leg in where it steps, and 1X 3Volt motor for each leg to imitate the Gait motion. I'm not using gears as it causes way too much friction, increases the centripetal acceleration I need, it's hard to ever have perfect syncronized gears when I'm using 2 different motors, AND I have to deal with gear ratios when all these problems can be solved simply by using a wire that tugs and turns axles at specific points and times (Thanks marklirh for the idea, you will see it happen!). My only real concern now is that I have a super huge breadboard that will decrease stability T_T
