How to set the force sensor rigid to estimate torque

[DuBaoSen]

I want to estimate the torque of the robot to the foundation, so I add a force sensor(sensor is child of foundation, robot is child of sensor).
But when the robot moves, the force sensor start to swing as a elastormer.
Please help me, how to make the force sensor act like rigid.

Hello,

this directly depends on the mass and inertia of the robot, and on the used physics engine. Try to switch to a different engine (e.g. Vortex) and see the differences.

Cheers
