CRLC technology integrates four core functional units—drive, transmission, locking, and sensing—into a standardized joint module, fundamentally eliminating assembly clearances, transmission backlash, and cumulative positioning errors inherent in conventional split structures. It supports unlimited bidirectional continuous rotation without mechanical stops and precise, stable locking at any set angle, enabling millisecond-level switching between compliant and rigid operating modes.

The rotary locking components of CRLC dexterous hand joints adopt rigid structures. Each joint is independently equipped with a miniature reduction motor, multi-turn absolute encoder, and fingertip pressure sensing system, forming an integrated modular closed-loop actuator that enables each phalanx to independently perform rotary locking actions. Sensors collect real-time data of contact pressure and clamping clearance deviation, driving the motors to dynamically adjust the rotation angle of each finger joint, thereby establishing an active compensation mechanism that corrects grasping posture through multi-joint coordinated closed-loop control. Relying on this mechanism, the dexterous hand can twist and grip bidirectionally toward the palm and back of the hand, performing flexible operations that exceed human physiological limits.

On this basis, elastic bodies arranged on the outer layer of finger joints provide passive compensation for clamping angle and clamping force. Through the synergistic effect of active and passive compensation, the hand can stably clamp workpieces within 0.1 mm in thickness, executing micron-level high-precision delicate picking tasks. Based on the engineering design featuring joint material tensile strength ≥1000 MPa, the dexterous hand achieves a single-finger static hook load of 80 kg and a whole-hand gripping force exceeding 120 kg, combining micron-level operational precision with hundred-kilogram heavy-load capacity.

CRLC灵巧手关节旋锁部件采用刚性结构，各关节均内置微型减速电机、多圈绝对值编码器与指尖压力传感系统，组成一体化模块化闭环执行机构，实现各指节均能独立完成旋锁动作；传感器实时采集接触压力与夹持间隙偏差，驱动电机动态调整各指关节转角，形成多关节联动闭环修正抓取姿态的主动补偿机制。系统依托该机制，灵巧手可向手心、手背完成双向旋握，执行突破人体生理极限的灵活作业。

在此基础上，手指关节外层设置弹性体以实现夹持角度与夹持力度的被动补偿，通过主动补偿与被动补偿协同作用，可稳定夹持厚度0.1mm以内的物件，执行微米级高精度精细拾取任务。基于关节材料拉伸强度≥1000MPa的工程化设计，灵巧手单指静态钩持载荷可达80kg，整手抓取力突破120kg，兼具微米级作业精度与百公斤级重载承载能力。

The CRLC robot adopts an integrated modular architecture, featuring high rigidity, high dexterity, and micron-level precision, which overcomes the limitations of single-task operations inherent in conventional robots.

Through the rapid reconfiguration of motion logic, a single unit can adapt to diverse production lines and complex working conditions, delivering composite operational capabilities that fully replace multiple traditional units.

Equipped with embodied intelligence, the robot endows its dexterous hand with outstanding grasping and manipulating performance. It can accurately and stably handle various irregularly shaped objects, and is widely deployed in industries including manufacturing, agriculture, commerce, healthcare, elderly care, cultural tourism, and scientific research; particularly in demanding industrial scenarios such as heavy-load material handling, precision assembly, and hazardous environment operations that are beyond the capacity of traditional robots, it can even more effectively demonstrate its irreplaceable operational capabilities.

Beyond conventional industries, customized CRLC humanoid robots built with special materials and dedicated processes can be extended for cutting-edge high-risk tasks including post-disaster search and rescue after earthquakes, fires and floods, deep-sea scientific investigation and space exploration.
