Budget Robotics - The Big Gripper Page 1 Copyright (c) 2006, Budget Robotics Budget Robotics Big Gripper Assembly Instructions The Budget Robotics Bigger Gripper kit offers a heavy-duty full size gripper at a low cost. It combines injected molded plastic gripper fingers, a high torque R/C servo motor (when purchased with the servo option), and strong but lightweight body construction using expanded PVC plastic and steel hardware. Big Gripper's "fingers" measure almost 3" long, and open wide enough to grasp a 12 ounce beverage can or tennis ball. The Big Gripper is ideal for use in robot ball collection competitions. At its widest the fingers open to a little over 3". Big Gripper measures 6" long, 2 3/4" wide, and 1 1/4" thick (with servo the total thickness is 2"). Weight with servo is 3.7 ounces. Lifting capacity is 8-12 ounces, but is conservatively limited by the wrist mechanism you use, if any. Full-open to full-close of the fingers requires approximately 90 degrees of servo rotation. The Big Gripper kit is assembled in under 20 minutes, and requires only a small (#0 or #1) Phillips head screw driver and 1/4" nut driver, or flat-nosed pliers, for construction. Note: Do not use the Big Gripper to grab or lift glass or other fragile or breakable objects! Not for use with open beverage containers, as the container may be crushed. Use at your own risk. The Big Gripper is not designed to lift objects heavier than 8-12 ounces.

Budget Robotics - The Big Gripper Page 3 Copyright (c) 2006, Budget Robotics Assembly Steps Step 0-Orientation and Setup Orient the six (6) plastic gripper hand pieces to familiarize yourself with them. The top of the gripper is identified by the "D" shaped cutout. The bottom of the gripper is identified by the rectangular servo hole. Remove the black screw from the white spindle of the servo. Set the screw aside for the time being, and don't lose it! Next, use the long servo horn to slowly and gently position the servo to its center position. Do this by placing the splined hub of the horn over the white spindle of the servo. Slowly
