4 wheels with 180 degrees turning
April 27, 2009
I saw a future concept car on a presentation on a documentary on Discovery Channel.
It had 4 motorized wheels, One in each corner (like a conventional car). But each wheel could turn 180.
It would mean that your car could drive in any direction, and rotate on the spot. Here's a link to a similar concept
It struck me that that would be nice to make with four GM10s mounted on four servos. One servo in each corner, and a wheel on each GM10. But then it struck me, WHY? OK, you would get sideways mobility, but that's the only advantage over the StartHere-design, or tracks. It might be cheaper than meccanum wheels, but the amount of coding to get it rolling glitch free seems staggering.
These are my first thoughts on the subject, what do you think?
