at Stanford University in California and his colleagues have built a 7.8-millimetre robot from polypropylene film that is just 0.05 millimetres thick. At each end is a thin magnetic plate that enables external magnetic fields to control the robot’s movement as it travels inside a body.
Depending on the orientation of the fields, the robot can be made to spin, flip or roll through liquids, on solids and…
