Many insects can jump several times their own body length. Locusts with their powerful hind legs can for example jump up to five times as high – 250 mm. We propose a high-power joint mechanism mimicking the locust leg structure in walking and jumping. The mechanism can produce power higher than motors mounted in the joint mechanism and separate walking and jumping using two motors. We also report the joint mechanism design principles.
