# F. Detect Other Conditions

In this sixth tutorial, you'll learn how to make your robot detect other conditions (e.g., surface drop-offs, the robot's pitch and roll, when the robot is upside-down, when the robot is bumped, etc.) using its IR line sensors and accelerometer.

## Tutorial Goals <a href="#tutorial-goals" id="tutorial-goals"></a>

The goals of this tutorial are to help you:

* Program a robot app that uses the IR line sensors to detect a surface drop-off
* Program a robot app that uses the accelerometer to measure the robot's pitch and roll
* Program a robot app that uses the accelerometer to detect if the robot is upside down
* Program a robot app that uses the accelerometer to detect if the robot has been bumped
