Mission Instructions
Your mission is to create a robot that can explore remote, narrow canyons. First, you will create a sample canyon system with both a left and right turn. Then you will design, test, and refine your robot until it can navigate the canyon system independently.
4. Pre-Code: Turn the Other Way
In a similar manner, can your robot manage to turn the other way? Let’s say if there’s a wall in front of the robot and a wall to the side with the sensor, it would be a good idea for the robot to attempt a turn in the other direction - as we are not dealing with dead-ends for the moment.
Try this code that will turn right if there’s a wall in front and a wall to the left
What happened?
Chances are your robot hit the wall with its back section. Oops. It seems it’s following the wall too closely. The GoPiGo needs space to turn ! Adjust your code and place your robot accordingly.
When you will build your canyon system, you will need to take those measurements into consideration. How wide should the corridor be? How far from the wall should the robot be?
Make It a Function
Now save your thinking as a second custom function. Make sure to name this one very carefully, too! If your last function was named “Turn Left”, this one should probably be named, “Turn Right”.
