Robot Arm Build Instructions
Place the servo in the lower part of the arm. Note which side the nub of the servo is on.
Fasten the servo with four nuts.
Make sure the servo nub is centered. You can use one of the servo horns that came with the servo to move it. Slip one side of the gripper base over the nub on the lower part of the arm and stretch it around the servo. Don’t stretch it more than you need to as you will stress the plastic. Press the other side onto the servo nub so the two parts are parallel.
Place the gripper servo under the gripper base.
Secure the gripper servo with four nuts. Make sure the servo nub is turned all the way counter-clock wise.
Place the right drive onto the servo nub. It should point almost straight out. Before pressing it onto the nub, rotate it slightly clockwise to make room for the guide. To check if there is enough room, align a hole on a guide with the hole between the right drive and the post on the gripper base.
Place the left drive so the teeth mesh with the right drive. It should appear to be a mirror image across the center of the arm.
Place the gripper lid onto the gripper. The post on the bottom of it will fit into the hole in the left drive. Hold the lid in place and check to see if the angle formed by the two drives is symmetric.
Secure the lid in place with a nut.
Alight one end of the guides with the holes near the post on the gripper base.
Secure the guides in place with one nut each.
Place the jaws so that the holes in them align with the holes in the end of the drivers and the guides. The jaws should be symmetric to the center of the gripper base and the inside faces of the jaws should be parallel.
Secure the jaws with one nut for each of the four screws.
You have now finished assembling the arm.
