Bristlebot with LDRs Becomes Light-Following Bristlebot
Bristlebots are great because no coding is required – they’re completely analog circuits that just go! But if you wanted them to go in a specific direction, how would you do that? Facelesstech has released their design for a light-following bristlebot that uses two LDRs to drive either side of the bristlebot (so you could turn it, somewhat – see video below for demo!). It’s pretty simple and pretty clever.
There is one thing missing from all my projects so far…..Something that moves. Bristle bots are very similar to hex bugs but are built from toothbrush heads and pager motors. I thought the idea of bristle bots was cool but they were no brains to them until i seen this blog post where you could control one with a light. Essentially this light following bristle bot is just two bristle bots side by side so it would be steered.
