Hello I’m DeokGon Yoo from A&G Technology in Korea, Universal Robot & RobotiQ Distributor


I have some questions about using the following products.

Model : FT-300


The test was carried out as follows.

1. Mount the 2-Finger Gripper, FT-300 on the tool chain

2. FT-300 Calibration progress, and we write COG and payload.

3. Grab 250g object in gravity direction

4. At the beginning, 2.5 N was measured, but after 1 hour 7 N was measured.


I am curious about the following.

1. Why is Force accumulated?

2. If there is a process that needs to be done to prevent the Force from accumulating

(other than Zero Sensor)

3. Is there a procedure to test the accuracy and repeatability of the FT-300?


Thank you

    The FT Sensor is intended for spontaneous measurement such as detecting when it touches a surface, apply a constant pressure over a short period of time, etc.  The signal will shift over time as it is affected by multiples factors such as temperature and humidity. Are you doing a zero sensor between each cycle? It is recommended to do a zero sensor using the rq_sensor_zero() function before taking any measurement. 

    The accuracy and repeatability of the sensor are defined by the recommended threshold which represents the smallest variations that can be detected by the sensor. Here are the recommended threshold based on the FT sensor version:
