A small machine formed like Pac-Man can transfer on the floor of water and round obstacles with out a motor. It may result in the event of small robots for environmental monitoring of lakes and rivers.
Daniel Harris at Brown University in Rhode Island and his colleagues constructed little units fabricated from plastic and rubber that may be moved in a controllable method by ripples in water.
The researchers first checked out how five-pointed stars, between 0.6 and 1.1 centimetres in dimension, transfer when floating in a tank of water. Ripples produced on the floor by a separate oscillating machine brought about …
