AI Technical Summary
Existing robotic fingertip force strain gauges suffer from problems such as weak signal, low sensitivity, difficult installation, severe temperature drift, and low reliability in multi-axis force measurement, making it difficult to achieve high-precision decoupled measurement and convenient initial performance testing.
It adopts a symmetrical, equiangularly arranged multi-bridge integrated structure, with internal orthogonal sensitive grids in the same strain direction to achieve temperature self-compensation, and independent detection of each bridge circuit through independent electrical connection terminals without common terminals. Combined with flexible circuit board and hot-press welding process, it is suitable for installation in confined spaces.
It achieves high-precision decoupled measurement of multi-axis forces, reduces temperature drift error, simplifies system structure, and improves installation efficiency and reliability, making it suitable for commercial applications in robot fingertips.
