Hi Nancy. I wish you luck with your project. You are more than welcome to use my ideas, but please do not use my images or copy my text directly. If you wanted to cite my blog in your material, that would be appreciated, but it’s completely up to you. I did not contact Kathy Ceceri regarding my projects that were inspired by her books. I simply link to it in case my readers wish to purchase her book. Good luck!

Our work will be copyrighted and publlished for profit. We’re wondering if you would like us to include some of your ideas and wondering if you know of the copyright implications. You do cite Kathy Ceceri’s Robotics. Was there any discussion surrounding that?

I’ll be signing up for your newsletter momentarily.

Our website needs a great deal of work. But it’s cited here to give you an idea of how we and our project look.

Thanks for all your wonderful ideas.

Nancy

Hi, Holly! I got mine off Amazon. Just search for “dc hobby motor” or you can find a link in the materials section of this post.

That stinks! I guess my suggestion would be to try angling the motor slightly. If the rubberband wants to slip off the motor, try gluing the motor on such that the shaft is angled upwards a little bit. The trick is to keep it as close to horizontal as possible, but the tension from the rubberband might be pulling it down too far, so I would try starting with it aimed a little upward. Good luck!

We have the whole thing done, but even with trying the eraser on the end the motor pin several times, the rubber band keeps coming off….any other suggestions??

That’s too bad, Shirley! I’m sorry you’re having trouble. My suggestions include 1) make sure you have new batteries, 2) give it a little push to get it started (sometimes it just has trouble overcoming static friction, but will keep going once it’s barely started), 3) lighten the weight of your car (not sure that would be possible), 4) make sure your wheels and axles are not too crooked (re-glue if necessary), 5) try a bigger propeller. Without seeing your car, it would be hard to know what’s going wrong. Good luck!
