Sheepdogs could be replaced by robots after scientists crack simple process

Discovery of how herding works could be used for human crowd control, researchers believe

Sheepdogs could lose their jobs to robots after scientists learned the secret of their herding ability.

Rounding up sheep successfully is a simple process involving just two basic mathematical rules, a study found.

One causes a sheepdog to close any gaps it sees between dispersing sheep. The other results in sheep being driven forward once the gaps have sufficiently closed.

A computer simulation showed that obeying these two rules alone allowed a single shepherd – or sheepdog – to control a flock of more than 100 animals.

The discovery has implications for human crowd control as well as the development of robots that can gather and herd livestock, the scientists said…
