I have commented before about nano-motion devices, but time marches on and Scientific American have a report (with videos) on a new design of magnetically-levitated mini robot – just a few millimetres in size.
You can also see the videos here:
Now I admit I found it impossible to understand either exactly how they worked, or what they were doing! But simply watching the videos of the robots scooting around was amazing and I felt like I was looking at something out of the future.
