The instructions from Parallax are not quite correct for use
with your robot so this webpage has a few modifications to make it work.
Be VERY careful not to loose any of the parts of your gripper.
We do not have spares! Work with the other kids assembling Grippers so you can help one another.
Open your bag and inventory the parts. I would suggest placing them
in 19 ziplock bags with numbers that match the first picture.
First half of Instructions. Complete to Step 8
- Get 4 extra long 2" standoffs from Amy
- Remove the bolts from your servos and turn them around so that the
center of the servos is closer to the front of the robot. (If you are adding tank treads do not do this)
- Remove the standoffs from your robot and replace them with the extra long 2" ones
- While your battery case is loose, insert two 3/8" bolts from the
inside (nut on outside) into the bottom most holes in the chassis near
the tail ball. Image With Bolts Reversed
Just put the nut on for now. These will hold the servo that controls the gripper on step 16.
- Finish attaching the 2" standoffs
- Replace the last bolts in the wheel servos
Second half of Instructions: Step 9 to 18.
A drill for step 11 is located on the center table
Adjusting the gripper servo position:
- Remove the screw from the servo horn and pull the servo horn off the servo.
- Upload the GripperOpen code to your robot.
- Now replace the servo horn with the arm with the rod facing towards the gripper at the front of
the robot. Picture
- Replace servo screw and tighten.
- Upload the GripperClosed code to your robot.
- Adjust the rods in the E/Z connector so the Gripper is fully closed and slightly
raised off the surface. Tighten the screws to hold the rods.
Congratulations! Your finished the gripper assembly!
If your IR headlights from lesson 6 are still wired up, ask Amy for a TV
remote control and you can drive your robot around and pick things up!
Ask Amy for help uplaoding the gripper remote code to your robot.
