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.
- Arduino Uno
- Mini servo * 2
- Metal clothes hanger * 1
- Ultrasonic sensor * 1
- Hot glue gun
- 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.
