Navigation Challenge

In previous activities you practiced basic skills for programming and manipulating the robot using the DC motors and feedback from the ultrasonic sensor.

The challenge is to collect all coins using the ultrasonic sensor for navigation. To prepare, you developed and tested a Follow the Wall strategy. Employ a similar strategy to this more complex navigation challenge.

Note: Your final solution should not use a hard-coded strategy. You should be able to modify your code for a challenge with different coin distances from the walls.

Instructions

The coins are approximately 110 cm away from the top wall and approximately 70 cm from the right wall. Use the data from the ultrasonic sensor to navigate the robot to collect all coins.

HINT

Start with a strategy that allows you to follow the wall at any distance that you specify. Then after following the top wall at the distance that gets you all the coins, rotate to the next wall and change the distance you want to be away from that wall using the same strategy.
