Design features for a car that will improve safety as it reverses.
In this Lesson, students will use the Brick Status Light and Display Block to program their wheeled robot to simulate visual signals for pedestrians, other car drivers, and passengers when reversing. Students will also use the Touch Sensor to simulate forward and reverse gears.
Ignite a classroom discussion around the following questions:
Ask your students discuss briefly what happens when cars reverse. Discuss how the reverse lights warn other motorists and pedestrians of what the vehicle is doing. Explain that the indicators on the dashboard communicate to the driver and their passengers which gear the car is in and the direction of travel.
Allow the students to select the tool(s) they find most appropriate for capturing and sharing their ideas. Encourage them to document their thoughts using text, videos, images, sketchnotes, or another creative medium.
Set up
PACK Rucksack HAPPY bumbag NAPAPIJRI DAY Black amp; qCEnC1xt Before assigning the next task, make sure that there is enough space for them to complete the task. It is a good idea to have students work on a big table or on the floor.
Build
Students will construct the Robot Educator base model, and then they will add the Touch Sensor.
Have the students perform the following building check before they program their robots:
Program
Allow the students to select the tool(s) they find most appropriate for capturing and sharing their pseudocode. Encourage them to use text, videos, images, sketchnotes, or another creative medium.

You can use the EV3 Software to demonstrate the Brick Status Light, and the three different modes of the Touch Sensor (i.e., pressed, released, bumped).

In the EV3 Software :
Robot Educator > Hardware > Brick Status Light

Students will build on their previous learning by creating programs that simulate forward and reverse gears in the following ways:
Allow the students to select the tool(s) they find most appropriate for capturing and sharing their pseudocode. Encourage them to use text, videos, images, sketchnotes, or another creative medium.
POSSIBLE SOLUTION: BUMP, WAIT FOR REVERSE GEAR
Differentiation option
Have the students utilize the EV3 Brick screen as a dashboard indicator.
They will further develop their programs by using the Display Block to incorporate the EV3 Brick screen so that the forward and reverse motion of the wheeled robot will trigger the screen to display arrows indicating the direction of travel.
Have the students integrate other signals, such as:
POSSIBLE SOLUTION: BUMP, WAIT FOR REVERSE GEAR WITH INDICATORS
TASK 1
6. Wait for the Down Brick Button (simulating change to reverse gear) to be pressed.
7. Activate the “reverse lights” (amber lights on the EV3 Brick).
8. Reverse the direction of travel for 2 seconds.
TASK 2
9. Wait for the Left or Right Brick Button to be “bumped”.
10. Activate the amber lights on the EV3 Brick.
11. Wait for 0.5 seconds.
