Making Your Servo Arm Attachment
It is much more satisfying having your first robotics project wave something rather than just seeing the servo move back and forth.
The Pole
Get one of the following items from around the house, the classroom, the store or a cafeteria:
- A drinking straw (preferred, nice & lightweight)
- A popsicle stick
- A small plastic spoon
That will be attached to the servo. Now we need something to attach to wave to us.
The Arm or Other Wavy Part
You can do one of the following things:
- Print out the Adabot head and arm in the green link below in PDF form.
- Print out any character you like on the printer. Or if you have a magazine or other material you are permitted to cut things out of, cut out your favorite character.
- On a piece of paper, use a pencil or crayon to trace your hand (fingers together) to make a hand on the paper.
Attachment to the Servo
Get some tape. Probably clear but any tape will do.
Cut out the waving part of the shape you want from the paper with scissors, if necessary.
Get your servo and one of the included horn pieces that has two arms 180 degrees apart. Using the short screw provided, connect the horn to the servo. The horn will press fit and then the screw will secure the horn. Never use one of the long screws or it could damage the servo.
Now tape your waving arm to the servo horn with some firm tape. As this will be moving, use some strong tape and go around things several times.
Or, I found using one of the long screws held my straw. The horn has some tiny holes to help, you might have to get the hole a bit bigger to get the screw in.
There you go, the servo assembly is complete! Now to hook all the rest of the parts together on the next page.
