I made my first robot following an example from the book Make: Arduino Bots and Gadgets . It is able to walk forward and backward, and detect obstacles and turn left and right accordingly.

It uses:

  1. Arduino Uno
  2. Mini servo * 2
  3. Metal clothes hanger * 1
  4. Ultrasonic sensor * 1
  5. Hot glue gun
  6. Blu Tack

The schematic is fairly simple:

And source code for the bot is available here.

Here is a video of it in action. The movement is a bit glitchy, I couldn’t adjust the legs into the best angle for movement.
