Make this 5,5 cm tall ATtiny based robot wobble with almost any IR remote.

Put it next to your TV and it shows its happiness each time you use your remote (This way at least someone gets some movement). Or you can have it dance to the signal of your sound system.

It's USB powered, so you can connect it to a USB port on a modern TV or any other USB type power source, so you can put it anywhere and use almost any remote to make it move at your will.

I made it as a present for a colleague and friend (she likes nerdie things). I called it Wiebelbot, as in Dutch (my native language) “wiebelen” means “to wobble”. The names wobblebot and wobble bot are already used by a number of completely different projects.

The simple and cheap remote control setup used can be applied in animatronics and many other applications.  I estimate the parts and materials cost less than 10 euro in total (I made it completely out of stuff I had laying around). The challenge when making the Weeblebot was in keeping it small. Building it somewhat larger, based on a larger ball would make things a lot easier. This Ible presumes some basic electronics and soldering skills. If you have some basic experience with Arduino (like me) it could make a great first ATtiny project.

Many thanks for the nice comments and the votes!

Step 1: Parts, Materials and Tools

An ATtiny 45 or 85 microcontroller
An IR receiver module tuned to the 38 KHz modulation frequency as common for TV remotes (similar to this one)
A small servo, for the ping pong ball scale at which I build the Wiebelbot I used a HobbyKing 1.7g ultra micro servo 
A capacitor, at least 22µF (I used a 100µF one)
A length of highly flexible wire (I used 0.1 mm2 wire)
A male USB connector plug (I made one from strip board, similar to this Ible)
An LED (any, I used a common 5mm red one)
A 220 Ohm resistor
Optionally, some shrink tube fitting the LED.

Construction and Finishing Materials
A ping pong ball
Some balsa wood scrap (I used 2 mm thick balsa sheet)
Some weighting material (I used 1 mm lead sheet, but some steel washer s should do it too)
Some sheet material to make the head (I used 0.5 mm polystyrene sheet, but cardstock would be great too)
Further decoration material, keeping it lightweight: For the arms I use a couple of curtain rail eyelets, for the second eye next to the IR receiver I used a broken 5 mm LED.

Tools and Adhesives
Soldering Iron and solder for small scale work
Cutting pliers
A drill, a 2 mm and a 5 mm drill bit
A 19 or 20 mm drill bit plus a press drill or alternatively bent scissors (not shown, I will explain the alternatives)
Marker pen, sanding paper, hobby knife….
Super glue, optionally some hot melt glue
A setup to program the ATtiny (I used a setup as described here)
Optionally, a solderless breadboard and jumper wires and tape for testing
An USB power source and a remote

<p>Just wondering if there's a way I could take this circuit and modify it to turn my PC on/off</p>
<p>sooo impressed...thanx fr sharing,,keep posting more..</p>
It's sooo cute!!! &lt;3
Awesome! If you do go for in internal battery it could possibly pull double duty and act as the ballast hanging off the servo horn... that is if it fits....
Indeed.<br><br>In a next build I would keep al electronic and electric parts together. I could have the servo, battery and all serve as ballast. I would need to find a good place to put the IR receiver module though, also moving then. Maybe If I could make an IR transparant body...
How cute can something be??? <br>Well, this project gave cute a new name: Wiebelbot. <br> <br>-Emily-
Fantastic! I was wondering how I could make my Vibrobots (bibberbeestjes) IR controlled. I think you just led the way :-D
This is soo cool! This deserves a vote and a patch!
It really is a cute little fella. That's a novel idea, putting it next to the TV so that it responds to your channel surfing. Nice work.
How could I not approve! It even looks like me!
It is so adorable!
