CD-BOT

Let's Make Robots Robots
1

This is a very simple robot which only has two wheels made of old CDs. Its brain is a motoruino and uses a sonar to detect and avoid the obstacles. On the video you can watch him navigating around, using the battery wire as a support to keep the balance.

Wheels

I’m not sure how good your traction is with such a small contact surface. Have you tried splitting a lenth of rubber tubing and putting it around the disc?

It works well like that, the

It works well like that, the speed and the weight of the battery compensates the leak of contact.

I think that if I did that I would have to reduce even more the speed of the motors by PWM. At full speed it would fly :smiley:

Nice looking! I always wanted to build a CD bot :slight_smile: Maybe one day…

Arduino

Is there anyway to make the CD-BOT using the official arduino uno board??

thanks

Of course!

All you need is to get some motor driver to control the two motors.
