Excellent project! I'm going to build it.I also need more detailed instructions before I can start building.

This is a great project.I noticed that another author copied most of your descriptions into his project, word for word, after the opening paragraph. The Fritzing wiring diagram is identical too.I posted a comment in his project, which is https://www.instructables.com/id/Ultrasonic-Motio... It's sad that someone would copy another author's descriptions and pretend they are theirs. ----- Sad!

We're all keen to publish our projects, even when a project is a modification of someone else's. But it's NOT NICE to copy another author's descriptions and pretend they are yours. After the opening paragraph, most of your wording is identical to that of https://www.instructables.com/id/Motion-Following... The Fritzing wiring diagram is identical too. ----- Sad!

Excellent description of a very interesting robot. What is the manufacturer and model number of the IR sensors? And where could I buy them?

Great project!!But I wonder about a different method: would it be possible to connect the jack for an audio source in such a way that it replaces the song signal Billy Bass uses, and not bother with the Arduino and motor shield?

Thanks. I'm now thinking the project would be easier if I applied the results of all your hard work. Again, it's a wonderful project!!

Great project! I'm just starting microcontroller projects and have lots to learn. Would it be possible to use two Arduinos instead of an Arduino and a Parallax? If so, which model and what shields would replace the Parallax method? Thanks.

Oh! Good idea. I didn't think of that because I was so focussed on taking good photos of the camera and transmitter attached to the truck.
