Lesson: OSD 20V ESD Getting Loopy & Precise

This lesson uses a set of 4 CoderZ activities to show how to use the Ultrasonic Sensor within Repeat Loops and also for precise navigation.  

1) Write code using the Ultrasonic Sensor within a Repeat Loop to have the EV3 spiral out of this maze:

Cyber Robotics 101: Obstacle Detection II >> Mission 6 (Red Spiral Out)

2) Try again, only this time spiral into the maze:

Cyber Robotics 101: Obstacle Detection II >> Mission 7 (Red Spiral In)

3) Manually drive through this challenge first, using the HUD and markers to get values for the code you will write:

Cyber Robotics 101: Obstacle Detection II >> Mission 8 (Diagonal Dilemma)

4) Finally, try again with a new starting point:

Cyber Robotics 101: Obstacle Detection II >> Mission 9 (Diagonal Dilemma Dos) 
https://play.gocoderz.com/dashboard/#/project-editor/4583287

5) Answer this question:

What does manually driving with the HUD allow you to do?
