Force and torque sensors
Six-axis force sensors measure three force and three moment components simultaneously, used at wrists, ankles and fingertips. Joint torque sensors measure a single axis.
The barrier is not the strain gauge but structural decoupling, calibration and thermal-drift compensation. Batch calibration capability is what determines whether batch delivery is possible.
End-of-arm sensing on Chinese collaborative robots is largely domestic now; the small-form, high-range units needed for humanoids are still ramping.
Basis: Industry-structure assessment (Tier C, our own judgement); contains no hard numbers.
Where the barrier sits
- Decoupling algorithm and channel crosstalk
- Batch calibration capability: number of rigs, cycle time, degree of automation
- Thermal drift and long-term stability
- Overload protection and batch consistency
Price and lead time
Price band pending. Must state: range, size, accuracy (%FS), whether data acquisition box and calibration certificate are included, and order quantity band.
| Data sheet | Status | What the basis must cover |
|---|---|---|
| Range and accuracy comparison | Pending | Force / moment range, crosstalk, repeatability |
| Cost breakdown | Pending | Elastic body / strain gauges / calibration / acquisition box |
| Calibration throughput | Pending | Rigs × cycle time × shifts |
