Robots' collaboration and communication are crucial in various domains, but ensuring their security is a challenge. Unauthorized access to communication clusters by robots can lead to serious incidents. Currently, robots operate within the edge computing paradigm, benefiting from powerful functionalities.To address robot communication security effectively, we present Edgemesh and Kmesh. Edgemesh is a network plugin for the kubeedge, securely and efficiently connecting edge nodes and robots. It enables seamless communication among robots across subnets, overcoming network barriers. Kmesh, a high-performance service mesh dataplane based on eBPF, offers advanced traffic governance strategies for robot scenarios. It utilizes eBPF-level traffic routing and robust security capabilities to support reliable robot tasks.Edgemesh and Kmesh are lightweight software solutions that enhance robot communication security and traffic governance. They unlock new opportunities and challenges in robotics.
