JumpRoACH versus VelociRoACH

In the quest for the most capable robotic bug (which is a quest that many roboticists seem to be on, because robotic bugs are nifty), some of the most exciting designs are inspired by the dynamic, multi-modal ways in which insects are conquering the world. Combining skills like running with skills like jumping can make little robots much more efficient movers, allowing them to go farther on a charge as well as helping them surmount obstacles and rough terrain.

We’ve written before about the advantages of multi-modal robots: by combining two different forms of locomotion in one platform, you can take advantage of (say) the efficiency and endurance of a ground robot with the range and versatility of a flying robot. However, designing one robot that can walk and fly tends to be both complicated and inefficient, which is why hetergeneous robot teams are often more appealing. Instead of trying to cram every capability into one robot, you just use several different robots with different specializations and find some way of getting them to work together. Like this robotic cockroach that can serve as an aircraft carrier for a robotic bird.
