rolling robot

The majority of robots done today have wheels and are therefore
"rolling robots". Did you have something other than a wheeled robot in
mind? Something like this perhaps? http://www.reconrobotics.com/

Gotta think like a Texas rancher, Randy. Anybody here match that
description???


Rollin rollin rollin
Though the streams are swollen
Keep them doggies rolling
Rawbot!
Rain and wind and weather
Hell bent for leather
...

Not this year.


We had to roll our doggies on out of here for lack of rain wind and
weather. Auction was End of Trail for them. East Texas was bone dry
this year. We got half a hay crop, where we normally get 3 or 4. So I'm
not thinking much like a cattleman these days. Maybe next year. On the
other hand, we've got a freezer full of truly organic beef the quality
of which you cannot begin to imagine buying from the market...

Unlike a robot you just set aside, and rechare later, when you want to
play with it, stock takes constant maintenance.

guys i saw something like this in net
http://robotics.usc.edu/~maja/teaching/cs584/papers/roball.pdf ..

thought it would b a very good challenge to do.so anyone have done it
before...can u help me with ur ideas...

   That rolling ball looks neat. Here's something similar (moving a
weight suspended below the device's center of gravity to cause
rolling), though of course not nearly as advanced. In the third pic
down on the right is "Buddy Smith presents CoffeeCan:"

I remember this thing, he didn't quite have it ready, you can see the
wires where he used a power supply instead of an internal battery. It
only moved along a line, and I don't know how it would turn or even if
he thought that far ahead.
   Sorry, that's all I got.

Wow, that sounds really awesome. Whoever did that was a genius.

Oh wait, that was me...nevermind.

I realized after I made it that I did it very poorly....an RC car
attached to the center shaft of the can and driving along it's rim
would've worked much much better and been a whole lot simpler.

But, then again, the goal was to learn, not to make something useful, so
I guess it wasn't all bad :)


Yeah, It turns out that I really should've used a better voltage
regulator..... or done the circuit a little better.

One 9V wasn't quite enough to move it. But 2 9Vs overloaded the 7805.
After the fact, someone figured out that I should've run one 9V to power
the logic, and then used both of them to power the motors.....

Oh well.... I still have that sitting in the living room :)

Nifty little bot, but white socks and sandals?!?!?

For an overall look at similar concepts -- coaxial drive, not footwear
-- there are some designs, working prototypes, and patents stretching
back to the 30s (or so) on coaxial wheel vehicles: you basically sit
inside and an outer wheel rotates around you. Turning was basically done
by leaning. They were particularly popular as a develoipment platform
during WWII as a means to traverse beaches. None ever saw commercial
production.

Haha....that's why I wear them!

At least I wasn't wearing a kilt at the time.

And, for the record, it's currently too cold, even here in atlanta, to
continue wearing socks+sandals....so I've returned to tennis shoes (aka
sneakers) until warmer days....
