I'm looking for a method to stop the gripper servo when holding an object.
I tried a few options:
1) servo potentiometer analog read
The values are noisy, and needs constant calibration, requires short delays between the readings (flood issue?)
2) Force sensor analog read (picture)
The values are noisy and depends on the touching surface.
3) Tactile button/pad digital read (picture)
similar to a bumper switch (picture) seems more simple to detect (digital signal) but so far nothing small to fit the gripper.
Any suggestions ?
