6 Tiny Robotic Ants, Weighing 3.5 Oz. In Total, Pull a 3900-lb. Car (nytimes.com)

Posted by msmash on Monday March 14, 2016 @04:00AM from the friends-of-ant-man dept.

Reader schwit1 writes about MicroTug, a team of six microrobots that weigh just 3.5 ounces (99 grams), and can move a car: Researchers at Standford University's Biomimetics and Dexterous Manipulation Lab have developed six miniature robots that have the pulling-power to move objects 2,000 times of their own body weight. The tiny robots and their inter-coordination are based on that of ants. The microrobot uses a special kind of glue on its feet that make them serve as sticky gecko toes. "Their new demonstration is the functional equivalent of a team of six humans moving a weight equivalent to that of an Eiffel Tower and three Statues of Liberty," said David Christensen, a graduate student who is one of the authors of "Let's All Pull Together: Principles for Sharing Large Loads in Microrobot Teams paper. Researchers' fascination with gecko adhesive is nothing new. In 2010, Stanford mechanical engineer Mark Cutkosky developed a Stickybot that could climb walls. A similar robot that could roll up on smooth as well rough surfaces was demonstrated by a group of researchers in Canada in 2011.

  And when they include the weight of the car in the statement, they are implying that the weight of the vehicle is somehow relevant.
  The main hurdle to "pulling" something is the friction, not the mass. If you put the Eiffel Tower on a set of rollers that had the equivalent rolling resistance that a 3900 pound car has, I betcha six people could pull it, too. If the brakes aren't on, one person can push a loaded railroad car. And if you use levers and pulleys (machines) for assistance, you can pull a lot.
  At many county fairs there used to be a popular show called "the tractor pull". People would compete in pulling a loaded sled with their tractors. They'd all start out able to pull the sled, but as the sled moved forward, so did a large weight that increased the friction between the sled and the ground. Only the beefier tractors could pull it the full distance, but all of them could pull it.

  It is relevant. Walk up to a car that's in neutral and sitting still and press lightly on the back end. It won't start rolling. It's not that it rolls very slowly. It doesn't roll at all. You could sit there for an hour and nothing would happen. You have to push pretty hard to get it started (as anyone who's helped move a stalled car can tell you), and while the details are very complicated, that force is roughly proportional to its weight.

For all i know. the touted synchronization is nothing more than each robot blindly executing the same timeline of roll, glue, pull from one synchronized starting signal.
  
  Granted, they are tiny winches powered by the LiOn batteries that i use in little helicopters and quad copters, and the glue is some magic stuff that can be engaged and disengaged at will by the robots.

  > the weight has no direct correlation with the rolling resistance
  Assuming high-school physics then, sure. Otherwise, while not really significant, weight impacts resistance where things like the tires compress and bearings have greater friction applied. It's not likely to be significant but it is certainly some. In a perfect world where things like the the tires do not compress due to weight than, sure. I'd say things like the tire compressing and added friction on the bearings are both directly correlated with the weight.
  It is (I've not done the math) likely a fairly insignificant amount but it's certainly a direct correlation with weight and 'rolling resistance.' Even a steel-on-steel surface would likely have some increased resistance due to weight - though much less directly associated with it. The weight might increase vibration or even cause minuscule deflections in the rolling surface like a railroad track. Sure, that'd be pretty damned minute, but it would exist and be something to account for - if one wanted to be anal.
  Note, this in no way really matters. As far as I know, the impact is really trivial and insignificant - and can be lessened. I'm merely adding this for completeness and to be argumentative, a little. I *might* be mistaken but I don't think I am?

  All good except I think you messed up on the foot-pound bit. Torque should be Newton Metres in metric.
  Joules is the measurement of energy. I suppose that would Calories in the U.S., Burma and Liberia.

  Foot-pound and pound-foot. It says in the latter article that the torque measurement unit is often referred to as foot-pound even though it should actually be vice versa. All the more reason why the imperial units are insane, heh.

But it's likely to have been relating to the rolling resistance rather than the static weight of the car. Putting the weight in the headline is pretty misleading, since it's not directly relevant to the amount of required force (polished floors, lubricated axles, etc.)
