I have been looking for a small robot or kit that can do the
following:

Detect an edge and turn around and go in a random direction when it
finds one.

Do the same when it hits and object or can't move forward.

Anyone know of any?

detect an edge... you mean the edge of a table, or a wall?

I had a robot that would do this when I was a kid (with walls)

it rolled around, turned when it hit things, smoked (you put
drops of oil in it), and had a tiny record player in it that said
"I am the atomic powered robot. please give my best wishes
to everyone"

Hi bjk,

many small kits can do that providing that they have sensors located
in their front.
You have the three choices:
- sonars
- lasers
- cameras (CCD or CMOS)

I think that lasers are somewhat too expensive if your budget is
tight.

You can even buy a Lego Mindstorm Robotics Kit which includes sonars
and up you can quickly program your robot to do just what you want
there. Otherwise, ther are more expensive robots such as the Surveyor
SRV-1 which as a little webcam (CMOS) in front of it.

Anyway, one good source of kits is this one there:

Have fun,

I would consider the iRobot Create (www.irobot.com). It has all the
features that you list plus some impressive expandability. It has a
great support forum, too.

Looking for a small form factor, something that can fit in your hand
size.
