A two-legged robot that walks at record-breaking speed has been developed by researchers from Germany and Scotland.
"RunBot" is the fastest robot on two legs – for its size. At 30 centimetres high, it can walk at a speedy 3.5 leg-lengths per second. This beats the previous record holder – MIT's "Spring Flamingo" – which is four times as tall but manages just 1.4 leg-lengths per second.
Two mpeg videos show RunBot walking at a steady speed and gradually learning to walk more rapidly.
