Fun with shape lock- Desk guard

Despite all of the robots I've built, I've never actually programed a robot before.  This is my step into the world of arduino. 

Chris the carpenter's desktop robot ( inspired me to build a desk robot of my own.  Most of my tools are back at college, so I’m building this guy with one bag of ShapeLock and two servos.

So far ShapeLock is great, it’s basically rapid prototyping for the 3D printer-less.  I’ve got the body built and a simple program that makes him look around.  There is a motor in his mouth that can launch a lego flying disk, but unfortunately I have no motor controller.  I might set up a switch behind his head that will trigger the disk to shoot when the tilt servo moves the head back.  More updates to come 


***can anyone guide me as to how you upload photos in the text section?  I see the picture icon with a little tree.  When I click on it there is an option for your "Image URL" and to the right of that there is a button you can press to upload your photos.  Somehow, though, I cant get my uploaded photos from that upload window into this text area.***


Looks around, shoots disk at intruders.

  • Actuators / output devices: 2 servos
  • CPU: Arduino
  • Power source: wall outlet
  • Target environment: desk

** You could try and make**


 You could try and make it reloadable, with multiple disks.

See the LMR FAQ.
Also: try it without your computer’s word processor. Just use LMR’s. 

As Duane mentioned a

As Duane mentioned a transistor would be the best way to control the fan motor since Arduino cannot handle the current draw. Check out this tutorial from instructables on using a transistor you can use any NPN transistor you have just check the datasheet to make sure it can handle the current draw of your motor.

Although this little gadget

Although this little gadget is hilarious, we should be very serious when it comes to our security, at home or even at work. For instance, homeowners and business owners buy all the time quality security gadgets and products, like the ones offered by this professional company at, to secure their homes and office buildings. If someone wants to feel safe and protected in his intimate space, why not to choose the best products from the market.
