Another robot story... The Battlefield Extraction Assist Robot (BEAR) is a machine being developed by the US military to extract a wounded soldier from the battlefield to a place where it is safer for them to receive treatment. BEAR is designed to travel over rough terrain and it's teddy bear face is meant to put the wounded soldier at ease (I've already weighed in on my belief about human looking robots being creepy, teddy bears...not so much!). The machine is remotely controlled and depending on the terrain it runs on tracks or tires. The six foot saviour can also tackle stairs and is narrow enough to fit through doorways. The BBC has more details here.
