Scientists are finding they can move the robot forward and backwards on flat surfaces, as well as in certain directions with an undulating, wave-like motion. Another positive is that the robots are cheap and easy to mass produce. They could change how doctors examine patients — serving as minimally invasive devices for biomedical diagnoses and treatments.
