Underwater robots are widely applied in various emerging fields

and the demand for developing underwater robots with flexible operation

clear display interfaces and agile cruise maneuverability is increasing.Aiming at these practical engineering requirements

firstly

a topological mesh communication system for Ethernet underwater robots based on lightweight IP(LWIP)protocol stack is designed.Under this system

a touch display remote sensing system is developed to achieve the operation more intelligent and lightweight

and the integrated technology of embedded hardware and software is adopted as the engineering realization means.At the same time

considering the defect of insufficient memory space in system on chip(SOC)central command unit of touch display system

a memory management algorithm based on neighbor address combination is designed to optimize memory in software layer.For the operation control system

an adaptive double closed-loop incremental PID algorithm is designed for the motion control system based on the motion characteristics of the vector propulsion device during steering.Finally

a series of joint tuning experiments between the operation control system and the touch dispay system are carried out.The experimental results show that the underwater robot has high running stability

the self-developed memory management algorithm has good memory optimization performance

and the motion control strategy has obvious effect when the robot is steering

which proves the uniqueness and rationality of the design of this embedded integrated system.
