The manufacturing process of AMRs is a systematic engineering project that transforms multidisciplinary technological achievements into stable, operational products. It encompasses design transformation, component processing, module assembly, system integration, testing and verification, and final delivery. The scientific rigor and precision of this process directly determine the product's performance consistency, reliability, and mass production capability. Therefore, the manufacturing process must adhere to the principles of standardization, traceability, and quality first.
The process begins with design transformation and process preparation. The mechanical structure drawings, circuit diagrams, and software architecture output by the R&D department must undergo process review to clarify critical dimensional tolerances, assembly sequence, and special process requirements such as welding and bonding. Based on this, the process team develops work instructions and inspection specifications, selects appropriate processing equipment and tooling fixtures, and provides pre-job training for personnel handling special processes to ensure that design requirements are accurately transmitted to the production site.
The component processing stage covers the manufacturing of metal structural parts, chassis frames, drive wheel systems, sensor brackets, and electrical housings. Metal parts are typically machined using CNC milling, turning, and laser cutting processes to ensure dimensional accuracy and surface quality. Heat treatment or surface strengthening is applied to stress-bearing areas to enhance strength and wear resistance. Polymer composite material shells are injection molded or compression molded, balancing lightweight design with protective performance. Circuit board and wiring harness processing must be carried out in an electrostatic-free environment, including surface mounting, through-hole assembly, wave soldering, or reflow soldering, followed by online optical and electrical testing to eliminate welding defects.
The module assembly stage assembles the machined components into functional subsystems. Chassis module assembly includes drive wheel installation, suspension and shock absorber adjustment, and motor and encoder alignment and fixation. Sensor module assembly ensures unobstructed fields of view and secure connections for lidar, cameras, and ultrasonic probes. Electrical module assembly covers battery pack fixation, main control and drive board wiring, and communication antenna installation, strictly adhering to cable routing and bundling specifications to prevent electromagnetic interference and mechanical wear. The assembly process utilizes torque wrenches, positioning fixtures, and laser rangefinders to ensure critical connections achieve designed preload and positional accuracy.
The system integration phase integrates all functional modules into a complete robot body. After mechanical and electrical docking, the system is powered on and initialized, navigation algorithms and task management software are loaded, the sensor coordinate system and odometer zero point are calibrated, and the initial path planning and obstacle avoidance verification is completed in the factory's standard test range. This stage requires iterative parameter iteration to eliminate hardware and software interface conflicts and ensure the stability of the perception-decision-execution closed loop.
Testing and verification include static and dynamic tests. Static tests verify the strength of structural components, electrical insulation, grounding resistance, and protection level; dynamic tests cover speed response, steering accuracy, repeatability, obstacle crossing ability, and multi-robot collision avoidance coordination. Environmental adaptability tests simulate high temperature, low temperature, humidity, dust, and electromagnetic interference to verify the robot's functional integrity under extreme conditions. All test data must be entered into the quality traceability system to form a performance file for each device.
Before delivery, a final functional demonstration and user training materials verification are conducted to ensure the robot can be quickly put into operation at the customer's site. Packaging employs shockproof, moisture-proof, and electrostatic protection measures, and includes a test report and warranty certificate.
Overall, the production process of autonomous mobile robots begins with design transformation, and through precision machining, modular assembly, system integration, and rigorous testing, a high-quality product integrating mechanics, electronics, software, and safety is built. Standardized process control and continuous improvement are the cornerstones for ensuring stable operation and large-scale deployment in diverse scenarios.
