TORQUE SENSING TECHNOLOGY

Ultra-Slim Torque Sensors for Next-Generation Robot Joints

High-bandwidth, EtherCAT-enabled torque sensing designed to integrate seamlessly with strain wave gearing and compact robotic actuators.

Engineered for humanoid, medical, and collaborative robots, Bota Systems’ torque sensors combine extreme thinness, high stiffness, and integrated electronics for safe, high-performance joint control.

Designed for Modern Robot Actuators

Our torque sensors are purpose-built for OEM robotic actuator design, with mechanical and electronic integration in mind from day one.

The ultra-slim hollow-shaft form factor allows direct integration with harmonic drives and other strain wave gearing, either inside the actuator or mounted externally, without compromising stiffness or bandwidth.

Fits standard strain wave gear flange patterns

Hollow-shaft architecture for clean mechanical routing

Integrates directly into compact joint stacks

 

High Bandwidth. High Stiffness. Real-Time Control.

Robotic safety and performance demand fast, accurate torque feedback. Our sensors use a high-stiffness spring steel design combined with high-speed EtherCAT communication to deliver precise torque and bending moment data at control-loop speeds required by modern robots.
