Title: Just An Idea...
Post by: voyager2 on July 05, 2010, 09:19:11 PM
Hi All,
Ever seen a coin/washer roll on its edge?
I have, plenty of times...
Now ever seen one roll down 6 steps and continue rolling unfazed?
I have.
How about a robot that can do that, under power with intelligent control!
One wheel with the MCU sitting low and a device to change the center of gravity to move forward and turn!
Imagine the possibility's with such a robot!
Has anyone built one? or even seen one?

Okay...
So imagine two servos inside a small tire with a PC board on shock absorber. Add a frame, correct circuitry, and you're done with the rolling down the stairs part.

For turning, find a way to shift the weight of your starwars-esque cruiser so that a servo-less small wheel hanging off each side will contact the ground and act as a pivoting point.

That's pretty much what I would do.
Just wondering if any one has done this (okay its a starwars thing)
