3-Axis Force Sensor for Humanoid Robots | AIDIN ROBOTICS

At AIDIN ROBOTICS, the 3-axis F/T sensor is designed as a compact, precision module that enables humanoid robots to perceive ground interaction forces and torques. It is primarily deployed at the robot’s ankle or foot region to facilitate stable walking and posture control.

 

Key Features & Specifications

Ø  Triaxial measurement: monitors vertical force (Fz) plus two moment axes (Mx, My) to capture both loads and twisting torques.

Ø  Compact form factor: designed to be integrated into humanoid robot ankle assemblies without excessive bulk.

Ø  High load capacity: supports force measurement up to ~2000 N (for the 3FT1000/2000 series) for robust performance under real walking loads.

Ø  Versatile mounting: can be employed not just at the foot or ankle, but also at other joints or structural interfaces where multi-axis force feedback is needed.

 

Benefits for Humanoid Robots

 

§   Improved balance and gait control:

Embedding a 3-axis force sensor in the humanoid robot foot enables real-time sensing of ground reaction forces and torques. This data is crucial for Zero Moment Point (ZMP) control, foot contact detection, and dynamic stability during walking or posture adjustment.

 

§   Force feedback for adaptive terrain:

When walking on uneven terrain, the humanoid robot ankle equipped with the 3-axis F/T sensor can detect subtle deviations in force distribution and adjust joint torques or foot placement accordingly. This helps reduce the risk of slippage or imbalance.

 

§   Reduced mechanical stress and damage prevention:

Having accurate force/torque feedback allows the robot’s control system to limit excessive loads on joints or structural elements. For example, undesirable shock or torque spikes can be mitigated through active or passive filtering, thus preserving the robot’s durability.

 

§   Compact sensor integration:

Because the AIDIN 3-axis sensor is compact, it can be more easily embedded into robot foot plates or ankle structures without compromising kinematic freedom or adding too much inertia.
