I'm looking for some direction on how to create a device that does the following: Imagine you have a yoga mat, I want a device that can roll it up and unroll it without a human intervening in the rolling process. I reliable this is a robotics forums but there doesn't appear to be a section for mechanical engineering so I'm posting my question here.
Could you start the rolling with some sort of scraping action, and use rollers to control it from there?
For example: http://www.youtube.com/watch?v=5xhbctEcAAA#t=90
The challenge would be making sure you stay oriented left/right to the mat being rolled.
