*** The 1.5V solar cells and little nokia vibrating motors can no longer be found online. I’ve written a new guide using new parts.***

I had a blast making bristlebots with my 4th grade science club a few weeks ago, so I started thinking up new ways to make simple vibrobots to give away as gifts.

I came up with this very simple Cockroach Virbobot. It only costs about $2.50 and 20 minutes of time to make. Super cute and super simple.[/vc_column_text][vc_tour][vc_tab title=”Step 1: Supplies” tab_id=”1409193658-1-86″][vc_column_text]

[/vc_column_text][/vc_tab][vc_tab title=”Step 2: Solder The Motor” tab_id=”1409193658-2-56″][vc_column_text]

Put the motor in one clip of the Helping Hand and a wire in the other. Solder on.

Do the same to the other side.

You want the wires point out.

BE CAREFUL! You don’t want to use too much solder, nor do you want to put your soldering iron on the tab for too long. Too much heat and you’ll melt the motor.

(Another reason I love the motors from Electric Goldmine is that they have very big solder tabs that are easy to solder. You want the ones with the blue casing, the pure silver casing ones melt with the slightest touch.)[/vc_column_text][/vc_tab][vc_tab title=”Step 3: Connect to Solar Panel” tab_id=”1409193892578-2-10″][vc_column_text]

Now align the two wires to the two solder points of the solar panel.

Positive and negative don’t matter in this case.

I like having my motor hanging in the middle. You can have it any which way you like.

Simple, no?

No, you don’t need anything else.

No, you don’t need a diode.

No, you shouldn’t try fitting a capacitor in there. (I tried, it’s not worth it.)[/vc_column_text][/vc_tab][vc_tab title=”Step 4: Paperclips” tab_id=”1409193940658-3-3″][vc_column_text]

Straighten out your two paper clips. I usually only use about 2/3rds of a small paperclip. It all depends on how long of legs you want.

Then bend them in half. We’re making nice little Vs here people.

Using the Helping Hand and Hot Glue Gun, glue the legs on.

Again, the position of the legs all depends on you and how you want the roach to stand. I like my roaches short and slightly angled forward. This way I can point him at the sun for max power.

(As someone was so kind to point out, don’t let the paperclips touch the wires that run to the motor, otherwise you’ll get a short. If you’re worried, just throw some hot glue between the legs and the motor wires.)[/vc_column_text][/vc_tab][vc_tab title=”Step 5: Enjoy!” tab_id=”1409194027299-4-3″][vc_column_text]

Your’re now done.

To make your roach extra cute I usually add on some little antennas via a single strip of thin wire.

You can also go full crazy and add googley eyes to make him extra personable.

I’ve made quite a few and given many away. Below are a few I have in my room (including one with a capacitor, something that didn’t work at all for me) to give you an idea of different ways to do the legs.

If you’d like one I have some for sale on my website, etsy store, and available as kits.

If you want a cheap and easy project you might as well put a cockroach together.
