RUN, LIZARD, RUN It’s not every day that a single study tells us something unexpected about lizards and robots, but such is the case for a new research project out of Australia. Researchers from several Aussie universities teamed up to study eight species of Australian lizards that run on two legs. They determined that we may have been wrong about why lizards move that way — and concluded that we might want to consider giving robots lizard-like tails to help with the bots’ own bipedal movement.

To keep tabs on the lizards’ body positions, the researchers tagged nine locations, including the tops of the lizards’ heads and their tails, with Liquid Paper. They then analyzed the footage using custom-built software. “There was an existing understanding that the backwards s...
