How Do I Share My How-To?

It's really pretty easy, pictures and videos of the steps it takes to complete your project are stored on YouTube and picasaWeb. Once your "final" video is stored on YouTube, your project will show in the listings on the site. All this is controlled by our Creator's Tools. Basically, you start a project by writing up the project idea.

Step 1. Sign up for a free Creator's Account to gain access to the Creator's Tools.

Step 2. Login

Step 3. Push the "Create New Project" button on the Creator's Tools. Make a name (you can change it later) for your project. And describe your plans to use as notes to guide the creation of the steps.

Step 4. When you've finished providing all the steps to your project, shooting the videos and saving to google video via the Creator's Tool Panel, you are ready to write the introductory paragraph with an interesting story of how you did it, or how you do it in the case of a professional services presentation.

Step 5. Last but not least create and upload the video (to YouTube) which is the video that will be used to summarize the project. If you were building a robot, this final video would show the robot running around, doing fun things that will inspire others to create their version of your project.

That's it... Watch the views and ratings for your project pile up along with the sales commissions! Or get a customer because you showed how you remodel a house.

FAQ About Becoming A Creator

Q. Why would I go to all that work, building something, then put it on a website like C What I Can Do? What's the point?

A. Actually, there are a couple of forms for a reward:

  1. You get rated as an author. Lots of good ratings looks good on your resume.
  2. You Make Money!

YOU Make Money when someone buys a part from You, and builds it into Their Version of your project. And, if YOU have a basement full of red leds and build a red led project - we'll send you customers who are inspired to build your blinking light device. If you sell PC boards, you may link to your own sales. Or sell your own kit online through your e-Bay store.

The same with books! We encourage project builders to make books. In fact, CwhatIcanDo is a great place to get rated as an author. 'Betcha get a better deal from your publisher...

Of course, it is possible that your project won't make you any money, because someone built something even cooler than yours (maybe even inspired by your project.) Maybe you just want to show your version of another project... It's done in the spirit of the web: Sharing ideas. And it's fun building a project on your own.

How To Build a Robot in a Box      ...     22538 Views
Author's name: WeRbots       

Low-Cost, super simple robot you can build yourself in a weekend.

This robot was inspired by my original attempts to build a "dog" bot.

What makes this neat is that it is simple to build AND it is expandable. Expanding is done by changing to a larger processor.

I`m building another version of the little control board using the picAxe 18x just to give myself more program space to make the thing behave simply.

Decisions About the Build     
I wanted to use the continuous motion servos I found on sale at Fry`s for 10 bucks. I had read a lot about the famous (at least to me): Boe Bot, which used continuous motion servos for driving. It would run slow at top speed, but I knew this would make it work even better without worrying about stopping as soon as it sees an obstacle.

I also liked the - servo head setup I used on the original Robo Dog I called dogbot which is written up somewhere else on this site. Dogbot had very "living animal" type head moves and I wanted to implement that same functionality in this little black box version of a Boe-Bot style DogBot.
