Jumping beats moonwalking – for a virtual robot: "Christopher MacLeod at Robert Gordon University in Aberdeen, UK, is intrigued by the idea of simulating how robots could move on the lunar surface. He uses genetic algorithms to evolve efficient gaits for robots on Earth.
He thinks that if such software is used to evolve the most efficient gait for lunar movement, the results might be quite different from those obtained using Earth's gravity. To move at speed on Earth, going down on all fours and travelling like a chimp provides more power and greater stability than running on two legs – but on the moon that may not apply, he says."
