Carrying, assembling, pouring tea, dancing, doing housework, running marathons, autonomous learning and operation—humanoid robots, as the culmination of advanced technologies such as artificial intelligence, high-end manufacturing, and new materials, are evolving from electromechanical control toward deep learning. As one of the best forms of embodied intelligence, humanoid robots are accelerating their development toward an intelligent, embodied evolution encompassing "perception-cognition-decision-execution," enabling widespread application across real-world industrial, commercial, and daily life scenarios.
As humanoid robots transition from laboratories to real-world industries and evolve from executing mechanical processes to achieving autonomous intelligent interaction, the precision, reliability, and functional stability of their core components become critical factors determining their sensory sensitivity, mobility flexibility, and service life.
Humanoid robots feature complex, highly integrated structures with miniaturized parts, a high proportion of thin-walled components, and multiple heat-sensitive elements coexisting internally—posing extremely stringent requirements for machining accuracy, minimal thermal damage, and long-term reliability. With laser processing and automation solutions offering micrometer-level precision, high adaptability, and flexible manufacturing capabilities, Han's Laser provides essential technological and equipment support—from core component fabrication to industry-transforming applications—accelerating the industrialization of humanoid robots and contributing to human well-being.
In the automated integration of laser welding and assembly inspection for key components such as precision structural parts, sensing units, and interconnect modules—including integrated joints, dexterous hands, sensors, connectors, actuators, batteries, motors, gear reducers, and ball screws—Han's Laser has established a comprehensive manufacturing system and supply chain. The company is capable of delivering full-stack, customized solutions tailored to the specific needs of industry clients.
Laser Welding for Precision Structural Components – Building "Robust Exoskeletons"
Structural components of humanoid robots are typically designed with lightweight precision, featuring high levels of integration and modularity, demanding extremely high accuracy. Taking the complex end-effector—the dexterous hand—as an example, achieving smooth, fine motor movements and precise grasping control remains a critical challenge to overcome.
Han’s Laser provides leading-edge processes and customized dedicated equipment for the mass production of humanoid robot dexterous hands, joint modules, and their core components. It offers a one-stop laser welding solution for micro-structured parts, irregular joints, precision housings, and internal transmission components involved in dexterous hand assembly. This series of machines has already been delivered in volume to major domestic and international robotics manufacturers for use in dexterous hand and joint module production lines.
By deeply integrating high-precision motion platforms, precision pulsed/continuous wave lasers, and accurate vision guidance technology, the system achieves high-strength, low-heat-affected, and highly consistent welding at micrometer-level precision, meeting the full lifecycle requirements—from prototyping to large-scale mass production—for precision structural components such as humanoid robot dexterous hands.

Laser Welding for Sensor Components – Enhancing Precision and Craftsmanship
Sensors are the core components enabling humanoid robots to perceive their external environment and interact effectively. A single humanoid robot requires over a hundred sensors throughout its body. These sensors demand not only fine, thin-walled, lightweight, and miniaturized structures but also higher sensing capabilities, anti-interference performance, and accuracy.
To address laser welding challenges in sensor manufacturing for humanoid robots, Han's Laser has developed multiple dedicated machines and customized intelligent automated production lines. This series of equipment has undergone long-term market validation and is now being delivered in volume to leading domestic and international robotics manufacturers for sensor production processes, helping both end users and sensor producers overcome key bottlenecks and difficulties in manufacturing.
The intelligent automated production line enables fully automatic loading and unloading, efficiently and precisely handling multi-component assembly, pressing, inspection, welding, testing, marking, and packaging. It supports full-process intelligent manufacturing from raw materials to final packaging.
● Full-Process Management – Every processing step is controlled by an MES system, with all parameters clearly visible
● High Cost Efficiency – Compared to manual lines, the automated line increases output capacity by over 50% and reduces labor requirements by 80%
● Flexible Smart Manufacturing – Compatible with multiple similar products, featuring short changeover times and one-stop fully automated production
Laser Welding for Interconnected Components – Empowering the "Neural Network"
Connectors for humanoid robots are critical components enabling power, signal, and data transmission, supporting high degrees of freedom and high-frequency reciprocating motion. Their characteristics—high-density interconnectivity, thin-wall miniaturization, and durability—demand extremely high precision in processing and exceptional tensile strength.
Laser welding overcomes many limitations of traditional joining methods. With minimal heat-affected zones and no mechanical stress, it allows flexible control over weld shape and strength, making it ideal for manufacturing precision components such as connectors. Han's Laser has introduced a series of laser welding machines specifically designed for humanoid robot connectors, along with highly efficient and precise automated production lines. These solutions offer significant advantages in high-precision processing, particularly in laser welding applications for high-speed connector shielding plates and conductor wires.
● Welding of 0.08mm-thick shielded plates in connectors ensures stable, low-resistance metal connections, reducing signal loss and interference while maintaining electrical continuity of the shielding layer and structural integrity.
● Energy output stability within ±1% ensures consistent welding processes, delivering high-quality and highly uniform welds.
Humanoid robots are evolving toward becoming more human-like, and in the future they will achieve multimodal integration by deepening the fusion of perception capabilities such as vision, hearing, and touch. At the same time, advancements in reinforcement learning and transfer learning will enhance the autonomous learning and environmental adaptation abilities of intelligent agents. Precision structural components, sensing units, and connectivity modules collectively form a hardware foundation that strengthens humanoid robots' motion accuracy, response speed, and intelligent upgrade potential.
Laser welding builds stable, reliable invisible bridges within humanoid robots. Han's Laser continues to deepen its expertise in laser welding technology through iterative innovation, maintaining close synergy between independent technological development and expanded application scenarios, delivering more efficient and precise laser-based smart manufacturing solutions to accelerate the realization of national high-end precision manufacturing industries, including humanoid robotics.
