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.
