A Vibrobot isn't really a robot, but it vibrates and "walks" or at least moves around.
This is a project I first saw on Maker Projects http://makeprojects.com/Project/Vibrobots/12/1
Needle nose pliers
Pocket knife with a second smaller blade, and an awl
Metal candy tin (such as Altoids)
Cable Ties (aka zip strips)
Electric motor with a part you can attach something to (if it's just a narrow rod sticking out that's hard to attach things to)
Two sets of: bolt, two washers, nut
2 x Jump cables (these are wire with aligator clips)
Heavy solid core copper wire (often used for by plumbers to ground your household electronics to a large pipe which goes into the ground)
2 plastic caps
2 "googly" eyes
1 x battery holder for two AA batteries
Step 1: Punching Holes
In the top punch
- a pair of holes where you'll attach the motor, near the edge
- one hole where the wires will run from the motor to the battery holder, near the edge
- one hole (in the middle) where you'll attach a "V" for the eyes
The battery holder will go inside the candy box. Run the wires through the hole to the top of the candy box and attach the alligator clips.
Step 2: Attach the legs.
Make two "V"s using the copper ground wire. Attach them to the candy box using the bolts.
Step 3: Attach the motor
Use the zip strip to attach the motor.
Attach a piece of the copper wire to the motor. This makes the motor unbalanced, and therefor vibrate. You can use a small cable tie to attach it more firmly.
Step 4: Attach the Eyes
Next, poke small holes in the bottle caps so you can attach the eyes.
Insert a "V" of copper wire into the hole in the center of the candy box cover. This will be for the eyes.
Step 5: Finishing Touches (Add a Face, Some "Clothes")
You can add bigger eyes
a playdough mouth and nose
maybe even some clothes
