The ant-shaped robots are moving large stones.

Robots are multipurpose tools. And even small robots can move large objects if they act as groups. Ant-shaped miniature robots are excellent tools for many purposes. They can take samples from ant nests and search for things like fungus between walls. The miniature robots can make chains and deliver information from cramped places. 

They can observe cables and search for damages from tubes and electric wires. The use of those robots is almost unlimited. They can act in medical operations where they can operate as miniature surgical tools. The jaws of those robots can act as surgeon knives. The miniature robots can carry miniature sensors that can search for many things. The cloud-based calculation systems are tools that can make miniature robots operate independently. 

The non-centralized data architecture makes it possible to turn those robot's computers into one entirety. And that turns those robots into a deep neural network where they share their calculation capacity. 

That gives those systems the ability to drive quite complex algorithms. This gives them very high independence. Maybe one part of those swarms doesn't have very high-power processors. But if they act as an entirety, those systems can be very effective.

Those robot ants can go inside houses and deliver information about the enemy headquarters. In the military world, those small robots can slip into the computer centers and then cut wires from those computers. Or they can deliver the oil spill response microbe to fuel storage. The same microbes can be used against oil damage. But in the fuel tank, those microbes destroy the fuel.  

Miniature robots can also act as testbeds for larger-size robots. Large robots can also operate in swarms. That makes the robot swarm technology suitable for large systems. The car or lorry-size robots can also operate as an entirety. 

The new robots can act as legos. They can form larger structures that can remove themselves. The self-assembly materials make it possible to create self-assembly and self-repairing surfaces and structures. In those structures, the material is formed of the separated robots that can touch each other.
