Instructables
This is a quick, easy project to build a tiny vibrating robot, a vibrobot. Vibrobots dance around typically by having an off-balance motor make them jiggle.

This one uses a vibrating motor from an old cell phone, a 3V watch battery, and a paper clip. A little soldering, some hot glue, and you've got a vibrobot!

Step 1: Gather materials

Picture of Gather materials
Here's what you'll need:
1. A watch battery (I used a 3V, but you can probably use whatever you find)
2. A motor from an old cell phone
3. A big paper clip
4. Soldering iron, solder, flux (optional)
5. Hot glue gun
6. Electrical tape
7. Sharpie or other dark marker

Optional but helpful:
8. Metal file
9. Rubbing alcohol
10. Needlenose pliers for the bending

Step 2: Make the legs - part 1

Ok, since the whole bot will be vibrating like crazy, I wanted to make the legs out of one continuous piece of wire -- it should be less likely to fall apart. The paper clip was the perfect size and thickness. Here's how to make four legs out of a paper clip:

First, straighten out the clip, then mark out six equal parts. On mine, marking every 1 1/16" worked out fine.

An important note about bending the paper clip -- go slowly! Take a few seconds to make each bend, or it could snap. Also, for the angles that are greater than 90, make them rounded, so there's not so much stress at one point. It took me three tries to finish the legs. (See the last photo.)

Now, bend a 90 degree angle at the first mark.

At the second mark, bend it back completely.




Step 3: Make the legs - part 2

At the third mark, make another 90, but this time angle it away from the end you started at. Now you're working in 3 dimensions. Both pictures below are the same step, from different angles.

it is the simplest vibrobot in all.
 Too bad this is technically not a real robot.  A robot must respond to stimuli. However, vibrobots are always fun anyway.  Good instructable!
Actually when you bump it thats a stimuli and when you bump them they go the other way don't they?
I suppose, if you were to interpret it VERY liberally.
I like getting technical

Superb. Fun and fast!
could you turn one of these into a water strider robot?
a strider bot is much different, check out the instructible for it!
You could also use a vibrating motor from a cheap vibrating motor from walmart.

Please do not solder to the battery, someday it will explode and you will get hurt. I am very concerned.

can you user a pager motor instead of using vibrating motor that looks like a watch battery...??
I'm going to add floats like the stride bot to this!!

Hehe, now all you have to do is put it in a fake cockroach and take it to Denny's!

Lmfao. Outback Steakhouse might be a more appropriate target. I have actually seen a cockroach there!
or some really high class restaurant
Or Waffle House. Cockroaches love that place.
Yeah... But I don't have any future in-laws who work there.... But could still work =)
I found a way to remotely activate it and put it on my teacher's chair this morning!

i just made one, its awesome!!! I'm taking it to school tommrow
If you have trouble soldering to a battery or other smooth surface than a drop of soldering acid on it will rough up the surface enough that it stichs better that solder to solder.
an easier way to do it is use a file or sand paper (lots cheaper also). the only reason i use these 2 is cause no where i no sells solder acid
Good its good as fun but I think if we do in this way lots of other ideas will come to other so you have done a good thing. I did not found your frofile but I think you are in good age and doing good, carry on God bless you.

This is a variation, get a soul. BTW: Great job Pepik.
OOOH, harsh. :)

hey pepik what kind of cell u get the motor ouf of
pepik (author)  Charger_066 years ago
The motor came out of a Samsung A460 that I used to use on Sprint's network.
thx
hehe...love this bug +1
