BEAM Headbot

Looks for light or darkness

Well here my latest build. is a Headbot from the Junkbots book, I tried using photo transistors for light sensors but it was not really working, then I pulled two small solar cells and it made the trick, still I am looking for other sensors to use, I would like to use the solar cells to power the bot :P I tried to hook up the cells with the battery but it reduced the sensitivity and movement considerably

Any ideas for good sensors??

Here's a link to a very nice BEAM wiki that includes circuit diagrams and other good info.

Noise0 has also posted a good example right here on LMR.
