1. Weighing things; 2. Target positioning; 3. Repetitive force; 4. Constant force, etc. The application of weighing force sensors on robots is far more than these. In short, in terms of force detection and control, weighing force sensors are inseparable.

1. Weigh something
When the robot grabs things, the load cell can distinguish them according to their weight. This can also be used to differentiate between different components that look similar. However, in real life it is very helpful to know if you have the correct object in your gripper, or if an object has fallen, and it can really help you in your production process. A force sensor can easily do this.
2. Target positioning
We often meet with customers who often believe that the only way to locate and quantify parts is with vision sensors. But actually this is not the only solution. There is no denying that vision systems are a great way to locate or quantify parts, but it is also possible to use force sensors to find and inspect parts. It's one thing to determine where they are on the X-Y plane, quite another to determine what altitude they are at. In fact, to do this, a 3D vision system is needed. If it is a pile of objects, you don't need to know the exact quality of the whole pile of objects, you just need to go to the pile of objects to find them every time. The robot only needs to determine the height of the pile of objects, and then continuously adjust its grasping height.

Another search function that uses force sensors is the sensor's "free mode". This may be a parameter of underutilization of the FT sensor. "Free Mode" or "Zero Gravity" mode will allow you to "liberate" the robot's axes, which will allow it to increase its compliance. For example, if you want to tighten a part on a CNC machine, you can free up 2 axes to allow the part to snap together perfectly while still maintaining some grip. This allows all forces to be applied to the center
