Manipulator of multiple degrees of freedom has been widely used in all kinds of rescue and exploring robots. This paper regard a kind of 6 DOF manipulator controller as the design object.The data acquisition for WDD35D4 sensors is carried by the C8051F020 microcontroller and sent through a wireless transmitter NRF905 after encrypted.Then the wireless transmitter NRF905 of the manipulator receives decryption. Through data processing and the steering gear adjustment, the angle of linear potentiometer corresponds to the angle of steering by 1-1. Then it drives the manipulator to work out and simulate the same motion of mechanical arm controller, and make real-time synchronization control.

Modern day cloud native applications have become broadly representative of distributed systems in the wild. However, unlike traditional distributed system models with conceptually static designs, cloud-native systems emphasize dynamic scaling and on-line iteration (CI/CD). Cloud-native systems tend to be architected around a networked collection of distinct programs ("microservices") that can be added, removed, and updated in real-time. Typically, distinct containerized programs constitute individual microservices that then communicate among the larger distributed application through heavy-weight protocols. Common communication stacks exchange JSON or XML objects over HTTP, via TCP/TLS, and incur significant overhead, particularly when using small size message sizes. Additionally, interpreted/JIT/VM-based languages such as Javascript (NodeJS/Deno), Java, and Python are dominant in modern microservice programs. These language technologies, along with the high-overhead messaging, can impose superlinear cost increases (hardware demands) on scale-out, particularly towards hyperscale and/or with latency-sensitive workloads.
