How a hopping robot could conserve its energy

A new study shows that jumping can be much more complicated than it might seem. In research that could extend the range of future rescue and exploration robots, scientists have found that hopping robots could dramatically reduce the amount of energy they use by adopting a unique two-part "stutter jump." Taking a short hop before a big jump could allow spring-based "pogo-stick" robots to reduce their power consumption as much as ten-fold.
