Andrew - First robot

Primary image

What does it do?

Change direction when meet wall

Hi all! First robot ever, saying it's not great would be an euphemism, nevertheless I would be very glad to get some feedback from you.

How it works : two switches on the front, when it meets a wall, andrew goes backwards and turn, then turn the other direction and goes forward again (see video - about the video, sorry for the poor quality, I had to use a phone, I can post a better one next weekend)

What does it do?

Navigate around via ultrasound avoiding obstacles

Well, finally I've started to assemble my first go at building an autonomous bot, nothing fancy, nothing original just something to learn the ropes. I'm going for a 2WD design that to me seems to be quite ubiquitous.

As of the moment (May, 17th 2012) basically I've only glued together a couple of DVDs (following generalgeek's sugestion) to use as base, and then also hot-glued a couple of DC motors and a 3rd non-motor wheel to it.

Component-wise I'm only waiting for a couple of transistors to build an H-bridge (as sugested on a Dan M's post).
