The August 24, 2016 NASA news item: [New NASA Record Holder For Cumulative Days in Space][1] congratulates ISS station commander Jeff Williams for passing 520 total days in space - a new NASA astronaut record.

While I was contemplating the challenges of spending a few percent of one's entire life in a (very large) tin can, I noticed the two microgravity robot things with him. Where can I read more about them, or at least what are they called?

Then the one on Cmdr. Williams' left caught my eye - that looks like art! Where can I read more about the pattern on the outside of that unit?
