Microbots Tow A Chevrolet Volt – Video


It's Slow, But It Works

It’s Slow, But It Works

In this video, 6 tiny microbots tow a Chevrolet Volt. The microbots are capable of towing up to 2,000 times their own weight, an impressive feat for sure.

Yes, the “towing” is painfully slow, but it’s still amazing to see something so small have so much might.

Video description:

“Not only are ants impressively strong, they are also amazing team players. This research inspired by such teamwork examples how the ways that microrobots move effects their ability to work in teams. With careful consideration to robot gait, we demonstrate a team of 6 super strong microTug microrobots weighing 100 grams pulling the author’s unmodified 3900lb (1800kg) car on polished concrete.”

Old Glory Insurance, when the metal ones come for you…


Soon, they’ll turn into Replicators from Stargate.

Towing something on flat surface has nothing to do with the weight of the object, it’s all about the resistance.

Rolling resistance (force) is proportional to weight. For constant weight, power is proportional to speed, neglecting air resistance. Happen to be working on this very topic for my blog post.

Yes but vary a lot depending on the surface and their finish.
If you put this Volt on steel buggy and rail, it would be much, much easier.
Same weight, different surface need different pulling force.
Those robot are impressive.

It looks to me like all that is demonstrated here is that a number of small winches can pull a car toward them. The robots themselves don’t move, they just winch the car forward.

A more informative number would be the force they can generate rather than the mass they can move.

So, very small winches can pull a car very slowly.

I assume the impressive feat is not pulling a car slowly but rather 6 mini independent robots working together to pull a car slowly. My geuss is that this relates to work looking at swarms of mini robots and how to get them to work together to perform tasks Or it could be grad students messing about with stuff they found in the lab it’s realty hard to tell the difference these days.
