This Ankle Torque Sensor Bracket is specifically designed for the ankle joint torque sensing system of humanoid robots, providing precise fixation and protection for six-axis torque sensors. Manufactured using precision CNC machining technology, it guarantees perfect fitment with the sensor and robot joint, ensuring stable force transmission. As a core load-bearing component of the ankle joint module, its performance is directly crucial to the accuracy and stability of the robot's motion control.
Features
High Rigidity and Stability: Made from high-strength stainless steel or aerospace-grade aluminum alloy, the bracket effectively protects the sensor under dynamic loads such as robot jumping and running, preventing overload and zero drift.
Precision Interface Matching: CNC machining ensures high-precision assembly with harmonic drives, the sensor body, and the robot's limb structure, minimizing installation stress and guaranteeing measurement accuracy.
Lightweight Design: Topology optimization and machining processes reduce weight while maintaining strength and stiffness, helping to lower the inertia of the robot's ankle joint and improve its movement agility.
Environmental Adaptability: Designed for industrial environments, available surface treatments can provide good corrosion resistance and wear resistance, meeting long-term operational requirements.
