Hello i am reporting an issue that i am having with my robotic arm. The claw that is supposed to open and close on the arm is not functioning properly. The claw won't fully open or close. The only way we can open and close it fully is by doing it manually. The Claw only gets half way on both opening and closing. We oiled the claw because we wanted to see if it just needed extra lubrication but that didn't turn out to be the case. It seems that the gears that work the claw aren't working properly. The servo that works with the claw also seems to be in good working condition. Everything else seemed to be functioning properly on the robot after we programmed it. Do you know what could be wrong with the robotic claw on the arm? I am doing this for a class and help would be very appreciated.
Upgrade to ARC Pro

then remove the servo from the claw and check that it functions ok, does it have enough travel distance to open & close claw.
secondly check the claw without the servo, there may be some resistance at that point where it stops
do you have adequate torque on the actual servo to drive the claw?
