Shape-shifting robot compensates for damaged limb: "In the simulation, each Roombot alters its pattern of movement randomly every few seconds and assesses how those changes affect the quadruped's overall velocity. After being given 10 minutes to find its feet, the quadruped had increased its speed from 5 centimetres per second to 31 cm/s.
When one Roombot was then made to malfunction – instantly slashing the walking speed to 15 cm/s – the quadruped learned to adapt its gait. After a further 20 minutes the hobbled robot had increased its walking speed to 21 cm/s."
