# Lesson: 20V ESR Curves Ahead

Printer-friendly version
Objectives:

This lesson uses a set of 7 CoderZ activities to show how to make different types of turns in Cyber Robotics 101.

1) Follow the animated prompts to code a gradual curving turn in the Cyber Robotics 101:

LEVEL-UP to Basic Navigation II Pack
Cyber Robotics 101: Basic Navigation II >> Mission 1 (Roundabout Turn)

2) Write code to your EV3 make the opposite turn:

Cyber Robotics 101: Basic Navigation II >> Mission 2 (Roundabout Left)

3) Follow the animated prompts to tweak the code for a double looping path (check out the Tips to speed up the simulation if you want):

Cyber Robotics 101: Basic Navigation II >> Mission 3 (Roundabout Double)

4) Write code for a gradual curve to the right into the parking spot:

Cyber Robotics 101: Basic Navigation II >> Mission 4 (Left Curve Turn)
https://play.gocoderz.com/dashboard/#/project-editor/3647559

5) Now try the opposite curve:

Cyber Robotics 101: Basic Navigation II >> Mission 5 (Right Curve Turn)
https://play.gocoderz.com/dashboard/#/project-editor/4527598

6) Now try curved parking in reverse:

Cyber Robotics 101: Basic Navigation II >> Mission 6 (Curve Back Left)
https://play.gocoderz.com/dashboard/#/project-editor/4527606

7) Finally, backwards in the opposite direction:

Cyber Robotics 101: Basic Navigation II >> Mission 7 (Curve Back Right)
https://play.gocoderz.com/dashboard/#/project-editor/4527610

8) Answer these questions:

How are gradual curves coded in Cyber Robotics 101?
How do you speed up the simulation?
