With the characteristics of artificial intelligence, micro/nanorobots (MNRs) are considered to be one of the most astonishing and transformative technology in the world today, which will change the research paradigm and practical technology in biomedicine and other fields. In this presentation, I will introduce the communication behaviors between the individuals of (photo-) chemically propelled micro/nanorobots and the strategies for creating adaptive motion behavior to environmental signals, as well as clarify their physical and chemical mechanisms and design methods. It presents that MNRs can possess the ability to cross biological barrier, excellent biological/immune compatibility, good bionic tendency, and even highly sensitive ability to sense and track weak chemical signals in the biological medium in the body through reasonable design of its composition, microstructure and interface properties. MNRs can emit signaling chemicals and strong hydrodynamic signals to communicate with one another. With the help of these bionic communication signals, the swarms and flocks of MNRs can be formed to show intelligent collective behaviors, such as adaptive reconfiguration, obstacle avoidance, leader-follower hierarchy and predator-prey biomimicry. This will inspire us to develop the next generation of intelligent micro-nanorobots with specific application prospects and disruptive technologies.
