Joint Torque Sensor_renewal

Everyone talks about accuracy.

But in a joint that must repeat the same motion thousands of times, true accuracy begins with structure.

At AL.Robot, we start from fundamentals: how force flows, how strain gauges take stress.
Through FEM analysis, optimized gauge placement, and automated validation,
we build sensors that prevent errors instead of correcting them.

Accuracy by design — not by adjustment.
