Make a Driverless Car

Think about these questions:
• What is an autonomous car and how does it work?
• Where do autonomous cars get their directions from?
• What movements must the car perform in order to move through a series of city streets on a north, south, east, west grid?

Hints
Start by building a vehicle. You may use any of the suggested LEGO^® MINDSTORMS EV3 Driving Base models or design your own model. Make sure that there is clear access to the buttons on top of the EV3 Brick. They will be used to control direction in this activity.

Create a program to control your robot using a recorded set of instructions that will be given to it through the buttons on the EV3 Brick. Use these parameters:
• Up Button bumped, the robot moves forwards 30 cm
• Down Button bumped, the robot moves backwards 30 cm
• Left Button bumped, the robot turns 90 degrees left
• Right Button bumped, the robot turns 90 degrees right

Think about using arrays to:
• Record the movements that a user would input by pressing one of the EV3 buttons
• Use the data that is stored in the array to reproduce the corresponding movements

Communicate the results of your work by:
• Creating a video demonstrating your design process starting with your initial ideas and ending with your completed project
• Creating a presentation that connects your project with real-world applications of similar systems

Ask for feedback and conduct a self-assessment. Use the evaluation tools that your teacher has provided.
