Re: vertical movement for robotic arm

You might try setting/mounting the base for your robot on top of an old
carjack and run the screwdrive for raising/lowing the jack from a stepper
motor. Just a thought...

I am designing a robotic arm which will be attached to a fixed base.
I would like to have the ability for the arm to elevate between 12 to
18 inches. The actuator for this would be mounted on the base, so it
would need enough power to lift the entire arm vertically. The arm
would be no more than 2 pounds. What is the best type of actuator for
this type of application?
