What you will need
- A couple of card board boxes
- Box cutters or scissors
- painters tape, nine volt battery and of course LittleBits.
The Littlebits circuits you need are
- Four motors with mounts
- Power supply,
- Button (if you want to get fancy, you can use a cloud bit or a radio control bit)
- Latch (To indicate on and off)
- A few extension cables.
Its a fairly easy build when you get down to it.
Step 1: First the Cardboard
You want to find a couple of pieces of cardboard you don't mind messing up. Feel free to change the dimensions and let me know how it went. I found these sizes worked best because the motors aren't that strong.
You could paint them if you want, make sure to wait for it to dry before affixing bits.
Step 2: Collect Your Bits
Littebits are amazing circuits made easy product. If you are a tinkerer or builder or a know a kid who is you need to have these in your arsenal. They take the scary out of circuits by removing the need to solder. At our tech lab in school we use these all the time for grade 3-8 and the teachers!
You'll need 4 motors (and mounts_, a power button, power supply, a splitter, a latch(for telling the robot its on and off) and a few extensions. Place them together as you see them in the picture.
Make sure it runs before using tape to hold them in place. Remember, electricity is flowing in one direction here. You can mess up your circuits though, thanks to Littlebits, the magnets on the side will force you to put them together the right way.
Step 3: Get Your Painters Tape Ready
I assume, do to the cost of little bits, you may not want to permanently affix your bits to cardboard. Thus I recommend a liberal use of painters tape. Works wonders and also comes off. ***Make sure it runs properly before affixing the bits with tape***
Step 4: You'll Have to Do Something With Those Wires
Step 5: FLIPPERS
Turtles dont really have feet, they have flippers. Make sure that they are firmly affixed to the motors otherwise they will just fall off when you you start the power.
After this step. Have fun...
Never got around to building a shell or a head. I did have plans on connecting a couple of servo motors and having a moving head and tail under a shell. Unfortunately, you are limited with a nine volt battery with regards to power. Let me know if you take this project further.
