Leading Question

How can we use the Eye Sensor on the Code Base – Eye Forward robot to detect an obstacle in the Mars landing area?

Build

Code Base 2.0 – Eye Forward

Play

Allow students to explore the concepts introduced.

Part 1
Students will pretend the Code Base is a Mars rover that is tasked with detecting and clearing obstacles from the Mars landing area (GO Field). They will build a project in VEXcode GO together with their teacher, to drive the Code

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Base until an obstacle is detected on the Mars landing area. Mid-Play Break Students will observe how the green highlight feature moves as their VEXcode GO project is started. They will compare the movement with the highlight to the behaviors of the Code Base. Part 2 Students will add a LED Bumper Sensor to the top of their Code Base. Then, they will add a [Wait] and two [Set bumper color] blocks to their project to make the LED Bumper on the Code Base glow after an object is detected by the Eye Sensor.
Share Allow students to discuss and display their learning.
Discussion Prompts
If someone came to our class, who did not know about the Eye Sensor on the Code Base, how would you explain what it does to them? How did you work together to build and test your project? What else do you think the Eye Sensor could detect in our classroom? How could you test your theory?
Engage
Launch the Engage Section ACTS is what the teacher will do and ASKS is how the teacher will facilitate.

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

ACTS

ASKS

1. Hold up a marker for the class, and demonstrate each sense as you ask the class. Take the cap o to smell it, hold it to your ear to listen to it, look at it up close and far away, etc.
2. Guide students to the idea of using their ve senses.
3. Have students share their ideas about whether or not they think the robot can “sense” and why they feel that way.
4. Hold up the Code Base 2.0 – Eye Forward robot and show students the Eye Sensor on the front. You may want to pass the robot around so students can see the Eye Sensor for themselves.
5. Have students share their ideas about what might be an obstacle on the surface of Mars. Make a list of “Obstacles” on the board, as students name things.
6. Show students the Lab setup –the Field will be the Mars landing area, and the balled up paper will be an obstacle. (See the Lab 1 Image Slideshow (Google Doc / .pptx / .pdf) for the suggested setup for this Lab.)

1. If we didn’t know what this thing was, how could we gure it out? What do we see? What does it smell like? What does it feel like? Does it make a sound?
2. What are we using to gure this out? What do see, hear, touch, taste, and smell all have in common?
3. We use our senses to learn about the things around us. Do you think our Code Base can sense things too? Why or why not?
4. Guess what, robots CAN sense things – using sensors. This Code Base build has an Eye Sensor. What do you think that Eye Sensor might do to help the robot learn about what is around it? If our robot was in a new place, like Mars, could the Eye Sensor help it there?
5. Imagine a rover is trying to land on Mars. What would the Eye Sensor on the Code Base need to look for, or detect, to help the rover land safely? What obstacles might be in the way?
6. How do you think we can code our Code Base to detect obstacles, so it can help the rover land safely on Mars? Let’s nd out together!

Getting the Students Ready to Build Before we can start coding our Code Base to detect obstacles on the Mars landing area, we need to build the Code Base 2.0 – Eye Forward!
Facilitate the Build

Instruct Instruct students to join their group, and have them complete the Robotics Roles & Routines sheet. Use the Suggested Role Responsibilities slide in the Lab 1 Image Slideshow as a guide for students to complete this sheet.

Distribute
VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Distribute build instructions to each team. Journalists should gather the materials on the checklist.

Code Base 2.0 – Eye Forward build

Facilitate
Facilitate the building process.
Builders and Journalists should begin building based on their roles and responsibilities, like those shown in the Lab 1 Image Slideshow.
Circulate around the room to help students with building or reading instructions where needed. Ask questions about how the build is being constructed to keep all students engaged in the buildings process, and remind students to follow their Role Responsibilities if they need help taking turns.

O er
VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

O er suggestions and note positive team building and problem solving strategies as groups build together.

Teacher Troubleshooting
Remember to use white or light-colored paper or objects as the obstacles — The Eye Sensor uses infrared light to detect objects, and since dark-colored objects absorb infrared light, it makes it very di cult for the Eye Sensor to detect them. If the wires seem to be getting in the way for students, use a rubber band to pull them together, and you can tuck the bundle into the build if needed, to keep the wires from impeding the movement of the Code Base during the Lab.

Facilitation Strategies
Think about how your students will access VEXcode GO. Ensure that the computers or tablets that students will use have access to VEXcode GO. For more information about setting up VEXcode GO, see this VEX Library article.
Gather the materials each group needs before class. For this Lab, each group of two students will need a GO Kit, Build instructions, a computer or tablet to access VEXcode GO, a balled up piece of white or lightcolored scrap paper to act as an obstacle on the landing area. Students will also need access to a Field for testing.
The Eye Sensor uses infrared light to detect objects. Light-colored objects re ect infrared light and are detected more easily by the Eye Sensor. Dark-colored objects absorb infrared light and the Eye Sensor does not detect them as well. During the Unit, use white or light-colored paper for the obstacles to ensure that the Eye Sensor will be able to detect these objects.
Set up your Fields ahead of time, as shown in the image below, to serve as a testing area for the Code Base. Have these spread out around the classroom to allow students ample space to test their projects. Both Labs in this Unit will use the same Field setup, so you can leave your elds together from Lab 1 to Lab 2. The balled up paper is the obstacle to be detected, and the ‘X’ is the starting point for the Code Base in the Lab activities.

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Field Setup

Try a new starting position – If students detect the obstacle right away in Play Part 1, have them move the Code Base to a new starting location and try again, to experiment with object detection more. Does the Eye Sensor still detect the same obstacle? Does it detect something di erent? Why do they think that is?
Use the Get Ready…Get VEX…GO! PDF Book and Teacher’s Guide – If students are new to VEX GO, read the PDF book and use the prompts in the Teacher’s Guide (Google Doc / .pptx / .pdf) to facilitate an introduction to building and using VEX GO before beginning the Lab activities. Students can join their groups and gather their VEX GO Kits, and follow along with the building activity within the book as you read.
Use the Teacher’s Guide to facilitate student engagement. To focus on VEX GO connections in a more concrete or tangible way, use the Share, Show, or Find prompts on each page to give students an opportunity to get to know their kits in more depth.
To focus on the habits of mind that support building and learning with VEX GO, like persistence, patience, and teamwork, use the Think prompts on each page to engage students in conversations about mindset and strategies to support successful group work and creative thinking.
To learn more about using the PDF book and accompanying Teacher’s Guide as a teaching tool any time you are using VEX GO in your classroom, see this VEX Library article.

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Part 1 – Step by Step

Instruct
Instruct students that they are going to build a project in VEXcode GO to drive the Code Base until it detects an object on the Mars landing area (the Field). This animation below shows how the Code Base will move when this project is started.
Be sure to use light or white-colored objects to represent the “obstacle” on the landing area to ensure the Eye Sensor will detect this object. Students can remove the obstacle once the Code Base drives up to it and stops.

Model
Model for students how to build the project in VEXcode GO and test their projects on the Field.
Begin by showing students how to connect the Brain on their Code Base to their device in VEXcode GO. Because connection steps vary between devices, see the Connecting articles of the VEXcode GO VEX Library for speci c steps to connect the VEX GO Brain to your computer or tablet.
They will also need to con gure VEXCode GO for the Code Base. If necessary, model the steps from the Con gure a Code Base VEX Library article and ensure students can see the Drivetrain blocks in the Toolbox.
Drag a [Drive] block into the workspace and attach it to the {When started} block.

Add [Drive] block

Then have students add a [Wait until] block. Next, drag a <Found object> block inside the hexagonal space within the [Wait until] block.

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Add [Wait until] with <Found object>
Have students add a [Stop driving] block to have the Code Base stop driving when an object is detected.

Add [Stop driving]

Once students have built their project, have them name their project as Drive Until 1 and save it to their device. See the Open and Save section of the VEXcode GO VEX Library for device-speci c steps to save a VEXcode GO project.

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Model for students how to test their project on the Field. First, show them how to place the obstacle and the Code Base on the square with the”X.”

Place the Obstacle on the Field and the Code Base on the “X”
Ensure that the Eye Sensor, located on the front of the robot, is facing the obstacle.

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Eye Sensor faces obstacle
Once the Code Base is placed on the Field, have students select `Start’ in VEXcode GO to test their projects.
Select Start to test project
After the project is nished running, students will need to select the “Stop” button in the Toolbar.

Select Stop

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

For groups who nish early and need additional challenges, have them move the obstacle to a new location and test their project again.

Facilitate
Facilitate a conversation with students as they test their projects. How does the Code Base robot move in this project? Can you show me with your hands? How did the Code Base know when to stop? How do you know when there is something in front of you? If you were the Code Base, which of your senses would help you drive until an object?

Remind
Remind students that even though this is a small project, they may make mistakes and it may take more than one try to have their project work successfully. In order to encourage students to embrace the mistakes along the way, ask questions such as:
What mistake did you make that taught you something?
What part of the Lab made you think hard?
Was it di cult to line up the Code Base so that the Eye Sensor faced the object? What strategy did you use to line it up?

Ask
Ask students to name or describe a device or object that they think uses an eye sensor. Ask them if they have heard of a robot vacuum cleaner? Can they describe how the [Drive], [Wait until], and <Found object> commands might work with this device?

Mid-Play Break & Group Discussion

As soon as every group has nished testing their projects, come together for a brief conversation.

Project your screen so all students can see the code, or bring students to a central area where they can all see the code on your tablet or computer.

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Start the Drive Until 1 project and ask students to watch the code as the project runs and describe what they see. Direct students to describe what happens with the highlight feature, and identify that it stays on the [Wait until] block until the Eye Sensor detects an object.
How does the green highlight move when we start our project? Why do you think the green highlight pauses on the [Wait until] block? What do you think the highlight tells us?
Part 2 – Step by Step

Instruct
Instruct students that they will be adding onto their project so the Code Base signals when the Eye Sensor has detected an obstacle in the Mars landing area. Students will add an LED Bumper Sensor to their robot, then add [Set bumper color] and [Wait] blocks to their project to create a signal e ect.
As they test their projects, they will remove the obstacle when the robot glows. The animation below shows how the Code Base will move when the project is started. Once the LED Bumper on the Code Base glows, students will need to remove the obstacle from the Field. This is also shown in the animation.

Model
Model for students how to add the LED Bumper sensor to their Code Base.
There are many ways that students can add the LED Bumper to the Code Base. Below is one quick and easy way to add it to the top of the Code Base using only 2 Red Pins and the sensor. The LED Bumper Sensor will need to be connected to Port 2 on the GO Brain.

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Add LED Bumper Sensor and Connect to Port 2
Model how to build onto their existing VEXcode GO project and test it on the Field. If students need to open their Drive Until 1 project, model the device-speci c steps, as shown in the VEX Library articles in the Open and Save section. Have students add blocks to their VEXcode GO projects to recreate the code in the image below. The new blocks will have the LED Bumper glow red for 3 seconds to signal that it detects an object. The red box indicates the new blocks that need to be added to the project.

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Add blocks to have the LED Bumper glow
The [Set bumper color] block set to red will make the LED Bumper glow red. The [Wait] block waits for a speci c amount of time before moving on to the next block. The [Set bumper color] block set to o will stop the glow e ect. Once students have built their project, have them name their project as Drive Until 2 and save it to their device. See the Open and Save section of the VEXcode GO VEX Library for device-speci c steps to save a VEXcode GO project. Have students place their Code Base on the eld to test their project.

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Place the Obstacle on the Field and the Code Base on the “X”
Once the Code Base is placed on the Field, have students select `Start’ in VEXcode GO to test their projects.

Select Start to test the project
After the Code Base drives until it detects the obstacle, the LED Bumper should glow red for 3 seconds to signal that it detects an object. Students should remove the object when the LED Bumper glows green.

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Tell students that they will need to select the “Stop” button in the Toolbar after they remove the object.

Select Stop
If students nish building and testing their projects quickly, have them add additional Drivetrain blocks to their project to have the Code Base return to the start position. Encourage them to experiment with the di erent paths that the Code Base can take to get back to the starting point.

Facilitate
Facilitate students testing their projects and taking turns on the Field. As students are testing, ask them questions about the Eye Sensor, and how the Code Base will move based on the blocks in their project.
How is your Code Base going to signal that it has detected an object? What blocks are you using to accomplish this?
How far away from the obstacle is the Code Base when it stops driving? Can you show me with your hands?
What blocks in our project tell the Code Base to stop driving? Review the Using the VEX GO Sensors and the Coding with the VEX GO LED Bumper articles for information on the LED Bumper to help students who need additional support to understand how the sensors work in their project.

Remind

VEX GO – Mars Rover-Landing Challenge – Lab 1 – Detect Obstacles

Remind students that they should check their project and compare it to the image of the project, before testing. If one student built the project in VEXcode GO, their partner can check the code, before placing the Code Base on the Field and starting the project.

Ask Ask students, how do scientists explore faraway places? Scientists and engineers design di erent kinds of robots to explore areas that are too far away or too dangerous for humans to investigate. Scientists design rovers to explore Mars, unmanned submarines to investigate the ocean, and even y drones into active volcanoes to gather data!
How could scientists code a submarine to use eye sensors to explore the ocean?
How could scientists use eye sensors on a drone to help explore a volcano? What command would they use to have the drone y until it is near the volcano walls?
What other tasks could scientists code a Mars rover to do with an eye sensor?

If someone came to our class, who did not know about the Eye Sensor on the Code Base, how would you explain what it does to them? How did the [Wait until] block work with the Eye Sensor in your project, to make your Code Base drive and detect an obstacle? If the [Wait until] block was before the [Drive] block, would your project have worked the same way? Why not?
