Using localized magnetic fields and vision-based control to navigate single and multiple robots around virtual objects.
The possibilities seem to be endless for microrobots (robots smaller than a millimeter), from medicine to manufacturing. But there are also plenty of challenges. Dave Cappelleri and his team at Purdue have already tackled one of these challenges — how do you get something to move that is too small for a motor or a battery? Now they are tackling another: how can a microrobot use just the right amount of force to manipulate an individual cell? The answer lies in tracking them visually.
