Introduction First off, you should know that BEAM Robotics is a research and education organization dedicated to the promotion and construction of unorthodox robots and gizmos for fun and real world applications. This kit is designed as an entertaining and easy starting point for those who wish to explore the principles of BEAM philosophy.
Parts Overview This is the part you’ve probably skipped over unless either you’ve already got your circuit working and want to know more about why, or you’re waiting for a bus to pick you up and take you to work/school (please don’t read this while driving). Whatever your reason, here’s the poop: The circuit is made of five...
Solarengine Theory The Miller Solarengine (MSE) is a simple, effective Type-1 (voltage triggered) solarengine with configurable turn-on voltage and discharge time. The turn-on voltage is determined by the type of 1381 selected, and the discharge time configured by the size of capacitor C1. While the solarcell charges the capacitor, its status is monitored by the 1381.
Soldering - The Essentials: The most important skill needed to successfully construct your device is soldering. Soldering is melting a special metal (called, um..., “solder”) between two components to make an electrical connection. We can also use solder like glue, to build things out of metals. You must make sure to use electrical solder, and not plumbers solder, which is used for piping and really isn’t good for electronics.
Since we’re soldering directly on the circuit board (no holes), MSE Solar Cell 03/09 Solarbotics.com you will find it is easier to add some solder to each pad first, then remelt it when adding the part. Fold, fit, and pre-trim the leads of each part before soldering.

The Free-Form Miller Solarengine Find a solar cell without the circuit board on it? PN2222 Transistor Build your own “free-form” version! 90° 90° to the Side You will need a PN2222 transistor, a diode, a 1381 trigger (C or E), a storage capacitor (1000µF or higher), a timing capacitor (0.47µF to 10µF), wire, a motor and a solarcell (solarcell must generate 3.2V MINIMUM).
Trouble Shooting Well, you take yer six-shooter, line up the troublesome BEAM critter on a wooden fencepost and... aw, it’s really not that hard to fix this circuit. There isn’t much that can go wrong with this particular layout. Run through this checklist and see if you can isolate your problem.
Let’s Get Moving! The fact that you’re reading this means you have a working solarengine (or you’re bored and just filling time until the TV commercials pass to the next program). This section is designed to help you get something moving across your desk/floor/sibling/significant other. All the following locomotion ideas are well tested in existing BEAM machines, with some working better than others in different situations.
Here are some techniques we've found that are valuable when Techniques starting off in BEAM robotics. Instead of taking you many hours of experimentation, we've put them all on this single page! Keep super-glues away from anything you plan to solder - it results in some nasty fumes when heated! Brass tubing (commonly available at hobby shops) can be cut without...
Ideas for your Solarengine The Symet, Roundabout & Solar Flag Waver! If you want to construct something other than a Solaroller, you may want to try one of these devices - the "Symet", the "Roundabout", or the "Solar Flag Waver". The "Symet"...
Advanced Ideas for your Solarengine The Photovore Light-Seeking Robot! Note: Ok, we cheated a bit - this is a Solar Engine project from a while back using a PCB instead of the new PCB-on- the-back system. But the principles remain the same, so stop being so picky! The Solarengine lets you make some interesting solar-powered devices, especially ones that can survive in lower light levels with small solar cells.
The CassetteMech Solaroller It’s sooo much fun turning junk into something brand new. One of the tasks around Solarbotics is to keep an eye out for cool technology we can do exactly that - turn it into something it wasn’t! The CassetteMech Solaroller is one such...
Build your Device for Competition The Official Solaroller Race Rules Fig 1: Solaroller “Scooter” (Dave Hrynkiw, 1995) Fig 1: Solaroller “Scooter” (Dave Hrynkiw, 1995) Object: Given a maximum solar cell size of 806.5 mm (1.25 square inches), make a self-starting 150mm (6") robot dragster to race one meter (3.3 feet) in full sunlight (or 1,000 watts Halogen lighting).

The Official Solaroller Race Rules ~ continued ~ 5 - During racing, competitors must not physically touch or attempt to touch each other, however, competitors may attempt to interfere with each others light source by extending vanes or other devices over the 25mm (one inch) lane walls. Vane extensions must still fit within the size guidelines. 6 - Designers are not allowed to augment their competitor performance by the use of external light sources, or even subtle reflections off of watches or eyeglasses.
