Three potential methods are already on the table, which in lay-terms resemble laser tweezers, a light vortex and a conceptual rippling beam. Once developed, it could signal the end of traditional mechanical sample collecting -- and
just plain luck -- consigning robotic arms to the history books. Check the video after the break for science-tastic mock up of how it might work.
