● YiAxis Expert Advice: Our modular matrix (Φ30mm - Φ170mm) is categorized by Generation (Communication/Precision) and Weight Profile (Application Type):

   ● Step 1: Choose Your Generation (PRO-2 vs. PRO-3)

         ● PRO-2 Series: Prioritizes a proven, ultra-compact form factor. Ideal for standard CAN-bus communication and cost-sensitive automation projects.

         ● PRO-3 Series: Prioritizes ultra-high precision. Features standardized Dual-Encoder (2E) feedback and EtherCAT (EC) support. It offers superior thermal management and signal                      stability for 20+ DOF complex systems like humanoid robots.

   ● Step 2: Choose Your Model (PRO vs. PRO-S)

         ● PRO (Standard): The industrial-grade "Workhorse." Heavier and more robust, designed for Cobots and Service Automation where continuous 24/7 reliability is more critical than                        weight.

         ● PRO-S (Slim/Lightweight): The "Muscle" for Humanoid & Wearable Robotics. By optimizing the shell and bearing structure, PRO-S reduces weight by 20-30%                                                   (e.g., a Φ60mm PRO-S weighs 0.73kg vs.1.03kg for standard PRO) while maintaining identical torque output.

● YiAxis Expert Advice: Your choice should align with your research or deployment environment:

   ● T140A (1.4m): The agile compact humanoid. Best for human-machine interaction and educational research in confined spaces.

   ● T170A (Standard Bipedal): Our flagship full-scale platform. Engineered for advanced locomotion and bipedal balance research using high-torque PRO-S joints.

   ● T170B/C: Specialized humanoid variants optimized for high-payload arm tasks or specific distal precision.

   ● T170D (Wheeled): The logistics powerhouse. Designed for commercial service and factory mobility where stable, high-speed travel on flat surfaces is priority.

    ● Answer: Under rated torque, our modules maintain precision for over 10,000 hours. Consistency is guaranteed by our automated assembly line and precision-calibrated                   lubrication, ensuring every joint in your fleet performs identically.

    ● Answer: We offer versions with an integrated permanent magnet brake. Upon power loss, the brake automatically locks the joint to prevent "gravity drop." Standard versions           without brakes remain "back-driveable" for safety.

   ● Answer: With through-holes up to 40mm and top-access (axial) interfaces, cables pass directly through the joint center. This eliminates wire wear during 360° rotation and            drastically reduces assembly complexity in narrow robot limbs.

    ● Answer: We natively support CANopen (CiA 402) and EtherCAT. Verified for seamless integration with Beckhoff (TwinCAT), Siemens, and Inovance controllers, as well as           Linux-based systems via our open-protocol documentation.

    ● Answer: We provide comprehensive protocol manuals and PC software. For strategic partners, we offer C++/Python SDKs and ROS/ROS2 driver packages. We master the           bottom-layer physics so you can focus on top-layer AI innovation.

   ● Answer: A fully integrated YiAxis 6-DOF robotic arm achieves a stable system repeatability of ±0.02mm. We provide the high-resolution feedback needed for 3C assembly              and precision instrumentation.

    ● Answer: Yes. Our dexterous hands feature high-DOF and integrated force-feedback logic. By monitoring micro-actuator current at high frequencies, the hand can perceive           resistance and safely handle fragile retail items or laboratory tools.
