The four-wheel drive robot 'you can't escape'

The idea of a robot following you wherever you go, getting faster as you speed up and yelling "target found", may sound like a nightmarish vision from a sci-fi film.

But four-wheel drive vehicle, Idris, has been programmed to do just that by experts at Aberystwyth University's intelligent robotics group.

The electric vehicle, about the size of an Austin Mini, can pursue people, vehicles or anything it can "see".

Dr Frederic Labrosse told BBC Wales about the software which makes 400kg Idris run and why it could be very useful.
