This is an attempt to create a simple and compact photovore. Although it may not be visually appealing, it serves as a good starting point for beginners. It is a personal version of the Dozer photovore. The latest robot built is named Trooper, based on the Scoutwalker 2 design. It features a four-motor walker that is smaller than the original. Additionally, there is a five-motor walker design that utilizes five micro servos, described as cute. An old video clip of a lightstorm pummer is available, showcasing super-bright white and blue LEDs placed inside a white crystal rock to create a cloud-like display. Another robot, named Moon-Walker, is a two-motor walker inspired by Mark Tilden's designs, moving slowly like walking on the moon. Links to schematics for Black Vermin and Tank have been provided for fellow BEAM enthusiasts. The creator has experimented with various components, including capacitors and resistor values, and has worked on different leg shapes and weight balancing. Plans for future projects include building another walker and a photovore, although specific details are still undecided. The creator has also shared a page documenting Tank's earliest designs with pictures and video clips. The Strider project was canceled due to unsuitable servos for the desired speed. However, there are intentions to create a Strider-style bot if appropriate motors can be sourced.

The described circuit focuses on a compact photovore design, which is a type of robot that moves towards light sources. This circuit typically employs light sensors, such as phototransistors or photodiodes, which detect ambient light levels. The output from these sensors is fed into a microcontroller or a simple comparator circuit that determines the direction of movement based on the light intensity detected by each sensor.

For the four-motor walker, a dual H-bridge motor driver can be utilized to control the motors' direction and speed. Each motor can be connected to a dedicated output pin from the microcontroller, allowing for precise control of the robot's movement. The design should include a power supply circuit capable of providing sufficient current to the motors while maintaining stable voltage levels.

In the case of the five-motor walker, the additional micro servo can be used for steering or to provide additional functionality, such as raising or lowering a sensor. The use of micro servos allows for fine control and can be integrated with a feedback system to adjust the walker’s posture based on the terrain.

For the lightstorm pummer, a simple LED driver circuit can be implemented to control the brightness of the white and blue LEDs. A PWM (Pulse Width Modulation) controller can be used to create varying light patterns, enhancing the visual display.

In the Moon-Walker design, the two-motor configuration can be simplified with a basic chassis setup, ensuring that the center of gravity is well balanced to prevent tipping over during movement. The motors should be selected based on their torque ratings to ensure they can adequately support the weight of the robot.

The schematics for the Black Vermin and Tank robots should include detailed component layouts, specifying the values for resistors and capacitors, as well as the connections between the sensors, motors, and control circuitry. Proper documentation will assist other builders in replicating these designs effectively.

Future projects, including the Strider-style bot, will require careful selection of servos and motors to match the desired performance characteristics. Researching local suppliers for suitable components will be essential to facilitate the successful completion of these robotic designs.This is just my attempt in making the simplest and kinda smallest photovore. Well, it`s not that good-looking though, but it`s a great start for some beginners. It`s also my own version of Dozer photovore. Right here! Woah, it`s been a long time since my last update here my friends! Anyways, here`s my latest robot that I`ve built. Its name is Trooper, a scoutwalker 2 based. 4-motor walker. Real small than the original. Yes, it`s possible! Take a look at it here. Enjoy! Yes sir, it`s another 5-motor walker creation! It uses 5 micro servos, well. all I can say to this bot is, it`s a cutee! Please check it out! Enjoy guys! Click here ! I`ve also uploaded an old video clip of my lightstorm pummer here. The super-bright white and blue LED`s were inserted inside the white crystal rock thing (I drilled 2 holes), that forms a cloud-like look. A cool display though, on top of your TV set! Hi guys! Well, I just made another cool robot. It`s a 2-motor walker, inspired from one of Mark Tilden`s bots as seen on "Robots Rising" video (from Discovery Channel).

I named this bot "Moon-Walker". It moves slowly, like walking on the moon. Anyway, just click the link below to go to its page. Enjoy! ;-) Well, there`s nothing much on this update. I just placed a link on Black Vermin and Tank`s schematic diagram. This is for those who e-mailed me a few days ago and to all BEAMers out there. Here it is guys! I hope it would help you out, `coz these are the exact diagrams which I`ve used. I just played with some parts, namely the caps and resistor values to satisfy my taste. I`ve also made several kinds of leg shapes (really tough though!) and weight balancing. It was really "pure" hard work and patience. I`m not kiddin`! Anyways, I`m planning to build a certain kind of walker and a photovore, but I don`t know when and what. I just thought of making a Strider style bot or a smaller version of Black Vermin (just like the size of Walkman).

Well, I`ve been busy with many things especially with my family for quite some time. But right now, I`m craving to make more interesting robotic creatures. let`s just wait and see! Wish me luck! ;-) If you have any questions or anything regarding my work, please e-mail me or make a topic in Yahoo BEAM group, I`ll be there anytime. Thanks and happy BEAMing! Goodluck and best regards to all ! I have made another page for you guys (just to share with). It was all about Tank`s earliest designs and how I made it, with tons of pics and some old video clips too.

The Strider project was cancelled, sorry guys :-). Well, the servos I bought were not suitable for this type of bot because of its speed (RPM), etc. Instead, we could use servos in many walkers or even in wheeled robots. I could make a Strider-style bot if I could get those motors which Strider used. where the hell I can get those anyway (especially in my country) But right now, I`m on something else, and it`s gonna be cool. First of all, I wou 🔗 External reference
