Construction Notes: The BEAM definition of a symet is a symmetrical bot. It uses its simple design to avoid obstacles with a single motor and no sensors. Check out Solarbotic's Bestiary entry on Symets.

August 5, 2008: Well, I wasn't satisfied with the performance of the original beast. So, I decided to try the beast with some added caps and a different engine. I went for the 1381Q which triggers at 3.8V. I added 3 additional 3300uF capacitors. Since they are physically larger than the 1800uF capacitors that are the original ones, the brass ring did not fit any longer. I angled the 3300uF caps down to compensate.

The solar cell assembly and mounting remained the same. If you take a closer look at the bottom pictures, you may notice the pivot point is a bit sharper. It helps to let the bot tip to the side easier.

The performance is most acceptable now. Good solid burst of activity, though it does take a bit to charge all those capacitors.

Check out the larger pictures in the BEAM Gallery.
