[0002] With the rapid development of artificial intelligence and robotics, the application of intelligent service robots in home environments is experiencing important breakthroughs. Especially in the context of the increasing aging of the global population, the demand for service robots with autonomous mobility and intelligent interaction capabilities is growing.

[0003] At present, intelligent robot technology covers multiple fields such as speech recognition, robot control, visual recognition and autonomous navigation. Among them, navigation technology is the key to realize the autonomous movement of robots, and its core includes environmental perception, path planning, positioning and navigation control technologies. In terms of environmental perception, robots perceive the surrounding environment in real time through sensors such as laser radar and cameras, and can identify and track the location of obstacles and their dynamic changes. The path planning algorithm is based on the environmental map and target position, comprehensively considering factors such as obstacle avoidance, safety, and travel efficiency, and plans the optimal travel path for the robot to ensure safe and efficient navigation. Positioning technology ensures that the robot can accurately locate in complex environments and avoid errors and deviations by integrating multiple sensor data, such as inertial navigation, GPS positioning, and visual positioning. The navigation control system dynamically adjusts the speed and steering of the robot based on the path planning and positioning information to ensure that it travels safely and stably along the planned path.

[0004] By comprehensively applying these advanced technologies, robots can autonomously navigate and perform tasks in various complex environments, such as cargo transportation, personnel guidance, emotional communication, and elderly companionship, thereby providing intelligent services for families and other application scenarios, significantly improving the quality of life and work efficiency of users. The application of this technology is particularly important in home-based elderly care services, which will greatly improve the quality of life of the elderly, people with limited mobility, and other groups, and provide more convenient life assistance and health monitoring.

The implementation steps of this method include hardware construction, encoder data reading, implementation of the PID control algorithm, speed and angle setting, control output calculation, real-time control adjustment, and safety protection mechanism. First, a chassis frame 4 control system is built by connecting hardware components such as the hub motor 8, encoder, and drive circuit to the Arduino main control board. Arduino obtains the rotational speed and position information of the hub motor 8 by reading the encoder signal, providing feedback data for subsequent control. Then, the PID control algorithm is used to calculate the control output of each hub motor 8 based on the set target speed and angle, thereby precisely adjusting the rotational speed and rotation direction of the hub motor 8. During the control process, the system continuously monitors the feedback data from the encoder and the actual movement situation, and dynamically adjusts the PID parameters according to the real-time error to ensure the stability and accuracy of the movement of the chassis frame 4. In addition, to ensure the safety of the robot and its surrounding environment, the system also designs overcurrent protection and overload protection mechanisms to cut off the power supply in a timely manner in case of abnormal situations, avoiding hardware damage or system out-of-control.
