Termites inspire robot builders

US scientists have developed small robots that behave much like termites.

The insects build impressive, metres-high structures even though they can follow only simple rules and have no knowledge of an overall plan.

The Harvard Wyss Institute's robot brick-layers do something similar, sensing just the immediate area and taking limited cues from each other.

This video shows the robots in action.
