A new generation of micro machines have recently begun tugging random objects around Stanford’s Biometrics Lab. Putting insects to shame the latest micro tugs, or Tuggers, are able to pull over 2000 times their own weight. Equivalent to a human dragging a Blue Whale down the beach.
Weighing only 12 grams Tugger is lifting well above his own weight but that’s not all for this micro machine. Tugger can also drive forward, turn left or right and when he wants to get to work pulling on things he plants his foot down and winches away. The secret though is less in the winch than it is in the foot.
