Quite possibly my fastest fabrication to implementation for a full fledged autonomous robot. Rio, our holonomic robot, works; flawlessly too.
It was fabricated (mechanical and PCBs), wired, tested and ready to go in less than 12 days, quite a miracle given the failure rate in robotics, the lead time for procuring parts in Singapore and the paperwork involved.
Here’s Rio all wired up and good to go.
Don’t stare at the wheels too long, they make your head spin. (http://www.youtube.com/watch?v=Upio7feAY6w)
I love the drive system. Are those wheels a custom bit or can I get those off the shelf someplace?
The wheels are standard omni wheels. You can buy them at AndyMark (http://www.andymark.biz/am-0432.html)
The drive configuration is unique for a robot this size and requires a suspension module.
