Robotic Gripper
What do you command the motor of a gripper when you want to grip an object.
i mean once the object is gripped , and still the motor is running then, this will result in stall current.
Do people usually turn off the motor after gripping the object?
If yes, then isnt there a possibility of the object slipping off?

I've found that RC servo grippers drop what they're holding when you turn the motor off. So I use the pulse width that is close to the diameter of the object to avoid gear strain.
If a gripper used a worm gear then you could cut power and it would still hold, but I don't have one of those.
But will using a pulse width that is close to diameter of object will also result in stall current, right?
And in case of worm gear , will it experience gear strain if we cut power?
When you cut power to the motor a worm gear would hold position, so while current consumption stops, the gear experiences the strain of holding the position. I've seen worm gears and threaded rods used for their ability to hold position when power is cut. For small motors and loads this shouldn't be a problem, but for large loads it might exceed the strength of the materials and strip a gear.
