Bot name: Rhino
Description: This is Rhino, he was my fifth two motor walker but is my oldest surviving walker. Currently I'm trying to cut down on his rat nest wiring. I don't expect to add any improvements, just make him more permanent..

Bot name: Stryder (Dennison's version)
Description: This was my first four motor walker. His electronics were very nicely laid out, although he didn't walk so well. Had I understood the 'secret' to four motor walking back then I would have gotten him to work nicely. As it was, he traveled by making nice arcing circles. Oh well. I made another such robot, but it's been dismantled.

Bot name: DAWG
Description: Miller's "Double Articulated Walking Gizmo" otherwise known as DAWG. A small (about 2.5" long) walking 'bot with some interesting abilities in the way it gets out of a fix. It simply spins its front legs in one direction for 1/2 to 1-1/2 rotations (let's see you try that one!), and pulls it's frontaround and out of the way.

Bot name: "Sunscout 1.0" + "Testbed"
Description: Here's the profile views of "Sunscout 1.0" (my first solar powered walker) and "Testbed" (my first walker). These are both two motor designs, and here you can get a better idea on the principles of two motor, four legged walking. Both walkers are facing to the left, and the front pair of legs is controlled by the left most gear down motor, and the rear pair attached to the right gear down. You'll notice that the front gear down is angled up a bit, and the rear gear down is parallel with the surface. This means that the front legs lift and provide thrust, while the rear just provide thrust. Although simple, this arrangement is effective in most circumstances, but not for turning. We've come up with a gait modification to the circuit that allows this arrangement make effective short radius turns.

Description: One of Mark Tilden's Grad students, Matt Moses, was quite prolific in his constructing of walker robots for Mark to take out and...destroy. Well, Mark actually went from his comfy home in New Mexico out to the wilds of the Yuma Dessert (Desert? - always get that mixed up, and always makes me think of ice cream regardless what meaning I'm after), where he releases these prototypes into a very arid, HOT, and alkaline environment. These prototypes were constructed out of relatively inexpensive materials like hobby-grade servo motors, NiCad batteries, and high-strength nickel wire. Compared to the other robots you may see from other research institutes costing thousands, this quad of robots looks to have been built at a fraction of a single conventional explorer prototype. Mark had many interesting anecdotes about his trials and tribulations in the wilds of Yuma, Arizona, but we'll just wait for Mark to finish and release his research papers.

Bot name: Sunscout 1.0
Description: My first attempt at a full-time solar powered walking robot, which succeeded very well. Scout stands about 2" tall, 3-1/8" long and 2-1/4" wide. The Canadian quarter in this picture is the same size as an American quarter. The final design has changed a bit, with new leg layout and eyes added to the front.

Bot Name: Walker 3M
Description: This is my first 3 motor walker. It uses 2 of the rare BG Micro motors, manufactured by Nihon Mini Motor and 1 eject motor from a Minolta camcorder. This robot opperates by lifting it's legs while pushing backward. Unlike Walkman Jr, which uses a 4 Nv microcore (Nv stands for Nervous network). The microcore is a loop of Nv units that cycle pulses through to opperate the device and walks by essentialy falling forward, this one will use a branched bicore. The branched bicore has two 2 Nv branches. The first Nv has a delay half of the other neurons. The second is a full lenth delay neuron. What happens is it produces an output that is 90 degrees out of phase. That means that the output signals overlap instead of just loop one after another. Both the microcore, designed and patented by Mark Tilden, and my branched bicore use a 74HC14 schmitt triggered inverter, a resistor, and a capacitor for each Nv. One chip supports up to 6 Nvs, and the branched bicore uses all six.

Bot Name: MECI IV M
Description: This is my first 4 motor walker. It's also responsible for many of my "firsts." It's my first walker with a board based frame. The circuit board actualy becomes the frame for the motors and the legs! I also completed the whole bot in a single piece board (there is a cut and reconection at an angle to create the angled front, but it's simply an angled section). It's very sturdy, and I designed it in under 2 hours! With the upgraded motors, I've accidentaly stumbled upon a design that allows the robot to pick itself up! I'll be making an add on board that will cary the neural network that allows it to lift itself up. The motors shown on the old images were replaced with 4 of the famed BG Micro motors, manufactured by Nihon Mini Motor. The Maxon motors were too weak to lift the robot sufficiently. This robot is a very high quality
design, and it was kinda sad to remove and replace the motors, cause the bot was named for the motors source (MECI). I'll still keep the name, however I had to replace the motors though. It looks just as cool as it did. It'll have some extra wires and sensors.

Bot Name: Walkman Jr.
Description: Walkman Was originaly very different than it is now. The original design was large, bulky, and the two motors ended up getting stripped because the gears were too weak. I later used a motor from the eject mechanism of a camcorder and a walkman motor with a hand built gearbox. Walkman (as well as my three solar robots and BORIS, my muscle wire robot) were used on an episode of Algo's FACTory. (Sunday mornings at 9:30 on FOX, at least in my area). It's a children's educational show. Walkman Jr. accidentaly walked itself off of a table and the fromt gearbox (the one I built) was destroyed. I replaced it and the back motor (so they matched) with high quality gear motors. They are great!!! I also added eyes just after first getting it to work. When it's dark, it "sleeps." One of the most notable features is actualy the "head" made from a difraction grating (like on those action baseball cards where you tilt it and the image changes). It's there for appearance and to act as a barrier between the eyes, (though they don't do much of anything except cause the robot to sleep).

Bot name: Walker Ver2.0
Description: This is my first walker. I don't remember many details about it because it was canabalized for parts (motors) long ago. It is powered by a good old four neuron microcore and a 74HC245 motor driver. The asthetics aren't the greatest but this walker was meant as a proof of concept for me and nothing more.

Bot name: Walker Ver2.2
Description: This is my 3rd two motor walker and my reigning champion. It's definitely my favorite two motor design so far. The motor orientation is from one of Tilden's bots on Robots Rising. It works very well.

Bot name: Walker Ver5.3
Description: I'm now on my third generation five motor walker and I think I've ironed out all the wrinkles. This walker is absolutely incredible to watch and it pushed me through the barrier between building BEAM toys and building a true robotics research platform.

Description: The final touches of my walker. I added LED's so I can watch his gate. I would recommend this if you have a walker. It really is neat. This picture was taken when he was walking so that's why his back legs look out of alignment.
