Abstract

Some insects can jump to heights that are several times their body length. At smaller scales, jumping mechanisms are constrained by issues relating to scaling of power generation, which insects have resolved over the course of their evolution. These solutions have inspired the design of small jumping robots. However, the insect' solution for the power constraint came at a price of instability and limited control over jump performance and these drawbacks were inherited by the jumping robots inspired by them. This review focuses on the jumping mechanisms of insects and robots, the challenges it imposes on control and stability and possible solutions. Although jump stability might not be a critical problem for insects, it poses substantial challenges for engineers of small jumping robots, who hope to develop autonomous devices with improved mobility over rough terrain.
