Bot Name: Mite
Description: Mite is a photopopper made following Chui Yuan Fang's great tutorial on his site. Mite was my first freeformed popper and if you've built a photopopper kit, then go to Fang's site and follow his instructions to the letter. My bots would not have been possible without his help. Mite is also my fastest and most efficient bot. Hands down. He's even almost twice as fast as my photopopper kit even with the larger solar cell. Wonderful, compact design.

Bot Name: Wasp
Description: Wasp is robo-art based on the photopopper circuit ala-Fang. Wasp is my favorite bot and I think he really resembles a wasp. I love the idea that his back legs are part of the circuit and not just stuck on. The photos don't do him justice, I'll try to post better ones.

Bot name: Trundle 2
Description: Trundle is my second attempt at a photopopper laid out with the eyes front and back under the solar cells. This causes Trundle to be left hand biased. That is, he always turns himself so his left side faces the light pool. He also only moves counter clockwise around the light pool. No matter how you place him, he will reorient to those habits. He exhibits the same phototropism as a photopopper, but he meanders allot.

Bot name: The photovore
Description: A small robot, eating nothing but light. Would that be possible? It is easy enough if a rechargeable battery stores the energy in chemical form. Rechargeables and electric motors go well together. Unfortunately the robot would spend most of the day `sleeping'. In Dutch daylight - that is, under a heavy overcast - the little solar panel supplies about 2 mA at 3 V, say 5 mW. Using two 30 mAh NiCd cells that allows about half a charge per day, if the sun shines now and then a full charge is possible. But the most efficient motor I could find needed at least 15 mA to do anything, so it would use up an entire day's light within two hours.

Bot Name: Willie
Description: Willie is the immediate ancestor of the Photovore. He doesn't search for the sun, but for a 25 W lightbulb marking his battery charger.

Bot name: ?????
Description: One of my favorite photovores. It can reverse it's motors and turn kind of like my "Tracked Bot"

Bot name: PP 2.0
Description: This is a quite small photopopper made using the freeform method at Fang's site, it's very active and seeks out light well.

Bot name: Photovore 1
Description: This is my first Photovore, It appears to have phototropic behavior and is quite small.

Description: These are a few of the scrapings on my bench, and a robot or two. The 'walker' on the left is really a photovore, but the legs make it look cool so I added them! Both of these robot utilize free form electronics dipped in Plasti-Dip, making them waterproof (except for the motors), compact, light and strong. Only problem is that it looks rather funny.

Description: Here's some pics of a colony of photovores that I am working on. I have enough parts for 4 or 5 of them, so that's how many will likely be built. Update: You know, this is off topic, but I should really date my updates! Anyway, these are now free form photopoppers, no interesting twists.* Sigh.* But at least I finished two of them. Now, for the pictures....next update. I don't have any film. *Sigh.*

Bot name: BitBot 1
Description: Bitbots were how I first got into BEAM. About five years ago or so I build a small bicore (I didn't know it was a bicore then!) out of NAND gates. The idea was to create a two wheeled bot that followed light without too much difficulty. It worked. That was a long time ago, when I got into BEAM I found the Bicore schematics and said "gee, looks like bit bot." So The first things I did in BEAM was BitBots.

Bot name: BitBot 2
Description: Basically Bitbots are connecting two motors to the outputs of One bicore. From there you have a two wheeled robot. There are a few tricks involved to get it to do anything interesting though. First CDS cells are used instead of Resistors, to get the phototropic effect, and sensors are attached to the core to get it to avoid objects. In the past a source of great problems was obstacle avoidance, something that made me turn away from Bitbots for a while. I didn't just want the robot to avoid objects like the photopopper does, because then it's essentially a photopopper. Two Nv's controlling two motors. I needed some reverse, so that the bot could at least act somewhat intelligent. Sure you could add a reverser and some other stuff, but it was too unbeamish for me. I didn't want to increase the chip count above two.
