A team at Oregon State University have apparently taken another step toward giving walking robots a more human-like – and energy efficient – gait, by fitting them with artificial tendons. Existing robotic limbs struggle to recover energy through a springy gait, but the Oregon team have introduced steel cable tendons and fibreglass springs made from the same material as archers’ bows that allow far smaller motors to be used.
