Hi Everyone Here is my Boe-Bot.
It's a fun kit from Parallax that comes with a great book and bunch of parts. I knew absolutely nothing when I started and going through their lessons has taught me a lot.(well a lot more than I knew before) He has been configured to do most the basic stuff including:
Drive Perfect Circles
Navigating with bumpers
Follow a Flashlight Beam
Navigate with Ir LEDs
Navigate with Ping
In the video he is navigating with Ir LEDs and receivers
Well sorry it took me forever to actually make this post. In response to ignoblegnome and Ro-Bot-x's comments I made a short clip using the same hardware setup but with frequency modulation. It could definitely a little smoother and more responsive but I hope this helps to show how useful these can be depending on how you program them.
