The first photo is more reasonable, all positive values, but the second photo is problematic, why is there a negative value?

This is a father-son relationship

If you tell me how to solve it, I will be very grateful to you.

Hello,

again, if you do not post the scene, it is much more difficult to say what is going on. When the force sensor is compressed along its Z axis, the Z-force is positive. If it is extended along its Z axis, the Z-force is negative. When your foot is lifted, then the Z force should be negative. It of course also depends on the orientation of your force sensor.

Cheers
