A1B1 - My first Arduino Robot

I present you A1B1, my first robot. It is a tracked robot, based on the "Mini DFRobotShop Rover Kit".

My robot uses the following components:

• 1x Mini DFRobotShop Rover Kit
• 1x DFRobotShop Rover Mobile Robot Shield (with 3.7v LiPo)
• 1x Arduino Uno
• 1x DFRobot Arduino Prototyping Shield
• 1x HC-SR04 Ultrasonic Range Finder
• 1x Piezo Speaker
• 1x servo from Arduino Start Kit to move head

It is moving around, avoiding objects as best it can using its sonar.

Poor A1B1, its head was removed from its neck...
