An intelligent service robot is a robot that integrates advanced technologies such as artificial intelligence, perception technology, and machine learning. Its purpose is to provide a variety of services and support to meet the needs of people in daily life, business, and industrial fields. These robots can sense the environment, understand speech and images, perform tasks, and interact naturally and intelligently with human users. Areas of Application: Business Services: It includes services such as reception, shopping assistance, and information inquiry, and can be used in places such as shopping malls, hotels, and exhibitions. Health Care: It provides services such as drug delivery, patient companionship and health monitoring for hospitals and nursing homes. Educational Assistance: It is used in educational scenarios to provide auxiliary teaching, answering questions and other services. Family Services: Provide cleaning, handling, home control and other services to improve the quality of life. The hardware structure of the service robot includes several key components. The functions and roles of these hardware components are as follows: Controls: As the core of the robot, the control device is responsible for receiving and processing the data provided by the sensors, executing the corresponding algorithms, and issuing instructions to the driving device to achieve the various functions of the robot. High-performance, low-power ARM chips are often chosen for the control unit, ensuring that the robot has sufficient computational and storage capacity. Drive unit: This includes motors and drivers, which are used to execute the motion and action commands of the robot. The motor is responsible for providing power, while the driver converts electronic signals into mechanical motion. This part is the motion system of the robot, which determines the execution of actions such as walking, turning, and the mechanical arm. Camera: As the ''eyes'' of the robot, the camera is used to capture images and facial information of the external environment. These image data can be used for tasks such as environmental perception, navigation, target recognition, allowing the robot to better understand and adapt to the surrounding environment. Sensors: Sensors provide the robot with various perceptual abilities, including vision, touch, hearing, and distance sensing, among others. Angle sensors and current sensors reflect the robot's own state, while temperature sensors, laser sensors, ultrasonic sensors, infrared sensors, etc. are used to collect external environmental information, allowing the robot to perceive and understand the surrounding situation more comprehensively. Display and Audio: As an important part of human-computer interaction, display and audio devices realize the presentation and interaction of user interface. The touch display provides an intuitive graphical user interface, while the voice interaction system enables the robot to understand the user's instructions and respond accordingly, thus better communicating with the human user. Folinx Embedded has launched the FET3588J-C SoM as the main control platform for this intelligent inspection robot product to meet customers' needs for machine vision and high-speed interfaces. FET3588J-C SoM is developed and designed based on Rockchip's RK3588 processor, integrating Cortex-A74-core-6 + 4-core Cortex-A55 architecture. The main frequency of A76 core is up to 2.4GHz, and the main frequency of A55 core is up to 1.8GHz, which can efficiently process the information collected by patrol inspection; The built-in NPU with comprehensive computing power of up to 6 TOPS greatly improves the calculation speed and energy efficiency of neural networks,providing robots with powerful AI learning and edge computing capabilities, enabling them to intelligently adapt to different work scenarios. RK3588J supports a 48-megapixel ISP3.0, which enables lens shading correction, 2D/3D noise reduction, sharpening and haze removal, fish eye correction, gamma correction, wide dynamic range contrast enhancement, and other effects. This significantly enhances the image quality. With abundant interface resources, it meets the robot's access requirements for various sensors. More sensor access helps the device to collect environment data more comprehensively. This platform also supports external storage interfaces such as SATA3.0, USB3.0, allowing data to be locally stored. It also supports wireless communication methods such as WiFi, 4G, and 5G, making it convenient for users to query device information on mobile devices. The rich functionality enables robots to perceive and understand the surrounding environment more comprehensively. It also has high stability. The platform’s SoM has undergone rigorous environmental temperature and pressure tests, and can operate for long periods in harsh industrial environments ranging from -40°C to +85°C, adapting to applications in various scenarios.

Embedded systems play a key role in many applications, from smart home devices to industrial control systems. To ensure these systems continue to operate efficiently and maintain the latest functionality, firmware upgrades and remote maintenance become critical. In this article, we will explore how to perform firmware upgrades and remote maintenance of embedded systems. The importance of firmware upgrades Firmware upgrades for embedded systems are to fix vulnerabilities, add new features, improve performance and ensure system stability. Since these systems are often distributed across various geographical locations, remote firmware upgrades can significantly reduce maintenance costs and reduce downtime. Advantages of remote maintenance Cost-Effectiveness: Remote maintenance reduces the need for on-site maintenance, saving time and money. Maintenance personnel can diagnose and repair problems without having to visit the site. Quick response: Remote maintenance allows for quick response to issues. Maintenance personnel can take action quickly without having to wait to arrive on site. Regular maintenance: Remote maintenance also allows for regular inspection and maintenance of embedded systems to prevent potential problems from arising. Implementation of firmware upgrades and remote maintenance The following are general steps for firmware upgrades and remote maintenance of embedded systems: Firmware Development: First, firmware upgrades must be considered during the development phase. The development team should design firmware with remote upgrade capabilities. Remote connections: Embedded systems must be able to establish remote connections to external servers. This usually involves network configuration and security considerations. Remote server: Create a remote server to store firmware upgrade files and maintenance tools. This server should be reliable and have good data security. Firmware Signing: To ensure the integrity of firmware, firmware should be digitally signed to verify that they are trusted. Automated processes: Set up automated processes to trigger and execute firmware upgrades. This can be scheduled, on-demand, or manually triggered by the maintenance team. Monitoring and reporting: When performing remote maintenance, monitoring the performance and status of your system is critical. Also, make sure to generate reports to document maintenance activities. Rollback plan: Even if something goes wrong while doing a firmware upgrade, a rollback plan is needed to restore the system to a previous state. Security: Ensure communications and data are encrypted during transmission to protect systems from potential threats. Case study: Upgrading smart home devices remotely Let's say you develop a smart home device that can be controlled via a mobile app. You need to implement firmware upgrade and remote maintenance functions. Firmware Development: During the development phase, firmware is designed for your device that supports remote firmware upgrades. Cloud server: A cloud server was established to store firmware upgrade files and maintenance tools. Remote connection: Your smart home devices can establish a connection with the cloud server via WiFi or cellular network. Firmware Signing: All firmware is digitally signed to ensure its integrity and trustworthiness. Automated processes: Users can trigger firmware upgrades in the mobile app, or you can set up scheduled upgrades on a cloud server. Monitoring and reporting: The cloud server monitors the status of the equipment and generates maintenance reports.
