How do I found out what parts I need for a simple driving robot?

Hi

I'm very new to Arduino. I've bought a starter kit, and I've played with controlling LEDs, motors and all sorts of things. Now I want to take on my first big project. I want to build a robot that will just drive around while avoiding obstacles and if it detects a sound, it will follow it. I also plan on being able to have two modes for it: autonomous and remote-controlled, so it can do both.

Now, my problem is, I dunno what parts I need for this.

What I do know/believe I need is:

  • Battery pack
  • Sound sensor
  • Ultrasonic sensor for obstacle detection
  • 4 wheels
  • motors for driving the wheels
  • a chassis, build of tree, legos or something else
  • and the rest of the parts for the robot

Any tips at how I can approach this? Any good tutorials you know about that focuses on for example building a driving robot with the parts for the driving and controlling and so on so I can get an inventory list or something?

This is the place to start, and it has tutorials on just about everything you need.

I don't think you need a sound sensor.
Perhaps your best solution is to buy a kit of parts for about $27.

I don't think you need a sound sensor.

Don't you think it would be pretty cool if the robot would stop when you yell "Oh, NO!"?

Thanks a lot guys. I decided to go with a kit and see where it takes me!
