How to build a digital robot dinosaur

Scientists from the University of Manchester have created a "digital robot" of the biggest dinosaur ever to have walked the Earth - Argentinosaurus.

This animated sauropod has shown the researchers how these creatures would have walked, showing that supporting their 80 tonne weight would have stretched muscle and bone to the limits of its capabilities.

The team used a laser scan of the dinosaur's skeleton and mapped onto that its tendons and bones.

Here, Dr Bill Sellers, who led the study, describes how the model was able to "learn how to walk".
