With over 75% of biomass and biodiversity loss over the last 30 years, Earth's ecosystems are on the brink of collapse. This catastrophe is now in the scientific community called the sixth mass extinction. This decline is fueled by anthropogenic stressors like climate change, pollution, and land overexploitation and seriously threatens human civilisation, which depends on healthy ecosystems. To better understand and address biodiversity decline, we need to observe what is actually happening inside ecosystems. By teaming robots with keystone species like honeybees, we can turn their natural activities into a valuable ecosystem information source. By interacting with the bees inside their habitat, our robots will extract information collected by the foraging bees from the surrounding environment. By interconnecting these cyber-enhanced hives, we will create a scalable, self-sustainable, wide-coverage and high-resolution sensor network continuously surveying the ecosystem diversity. Our sensing system integrates micro-robots within honeybee colonies, not to replace the bees, but to complement and better understand their vital pollination service.
