The robot is fitted with:

  • Six reflectance sensors that can be used for edge detection and line following.
  • A buzzer for simple sounds and alerting to states and issues.
  • A 3-axis accelerometer, magnetometer, and gyro for detecting impacts and tracking orientation

but it can also be fitted with additional sensors such as ultra-sonics for obstacle avoidance.


The robot comes fitted with an LED on pin13 (as per the Arduino) and a button that can be used to start/stop the Arduino during battles and tests.  The following script shows how the button could be used to switch the LED on and off.
