Scientists Develop Tiny Swimming Robots A projected timelapse of tracer particle trajectories near a robot consisting of three motors tied together. The image shows an electronic device floating in a liquid. The device is surrounded by dark lines that resemble a magnetic field. To the right of the device, the dark lines of the field are particularly thick.
