Saying HI again. Still here building bots...

Hello again!

It has been ages since I have been on LMR and I missed you guys something fierce! :-)

I have just built another "generic" Arduino based bot (it WAS NOT fun getting the driver to install in Windows 8!!!)

(I will try and get a picture and more details up when I can, but basically it uses a Arduino Uno, a servo/Sharp rangefinder combo and a L293D bridge chip to control 2 very low power motors driving the wheels in differential form. Like I said, pretty generic.)

The A.S.R.B.

What does it do?

Navigate via GPS, Compass, and avoids obstacles using 5 IR sensors

Hi all, I'm Matt and currently a junior in high school. I built first robot called the "A.S.R.B." over the summer for the Authentic Science Reseach Program and I wanted to share it with all of you! *I'm going to apologize in advanced if my spelling/wording/grammar is terrible--It's been a long day and I'm in a rush to get this posted.* Using the chassis of the duratrax evader EXT-2, I built this robot from the ground up.  I swapped out the esc and dc motor for a traxxas 12t 550 that I had lying around, and the esc is now the traxxas xl-5.
