+
+Design cars that can park themselves safely without driver intervention.
+
+![Autonomous parking graphic](/static/coding/autonomous-parking/auto-parking-connect.jpg)
+
+## Connect
+
+**Think about:**
+
+* How do autonomous cars work?
+* What would it take to ensure that autonomous cars are safe?
+* What types of movements do autonomous cars need to perform?
+
+## Construct 
+
+### Build
+
+Build a @boardname@ vehicle that can park itself safely without driver intervention. Start by constructing this model:
+
+[![EV3- Robot Driving Base](/static/coding/autonomous-parking/ev3-robot-driving-base.jpg)](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-rem-driving-base-79bebfc16bd491186ea9c9069842155e.pdf)
+
+### Check
+
+Before you program, check:
+
+* Are all the wires correctly connected from the motors to ports B and C?
+* Are the wheels correctly installed?
+* Are the wheels rotating freely?
+
+### Program 
+
+Write a program that will make the robot turn three times in various ways.
+
+**Think about:**
+
+* How will you make the robot turn in different ways?
+* How can the robot make a three point turn?
+
+### ~hint
+
+Consider using these blocks in your solution:
+
+```block
+motors.largeBC.tank(50, 50)
+pause(500)
+```
+
+### ~
+
+### Sample Solution - Three Point Turn
+
+1. When the brick button is pressed, turn the driving base right and stop after 1.5 seconds.
+2. Turn the driving base left and stop after 1 second.
+3. Move the driving base forward for 3 seconds.
+
+```blocks
+brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
+    motors.largeBC.tank(75, 30)
+    loops.pause(1500)
+    motors.largeBC.tank(-30, -75)
+    loops.pause(1000)

+
+* Parallel parking
+* Angle parking
+* Perpendicular parking
+
+### ~hint
+
+Document pseudocode for your program before choosing programming blocks.

+### Sample Solution - Parallel Parking
+
+1. When the brick button is pressed, drive forward in a straight line for 3 rotations.
+2. Wait for 1 second.
+3. Reverse motor rotation while turning for 1.5 rotations.
+4. Reverse motor rotation while turning the other way for 1.5 rotations.
+5. Drive backward in a straight line for 0.5 rotations.
+6. Drive forward in a straight line for 0.5 rotations.

+6. Drive backward in a straight line for 0.5 rotations.
+7. Set brick status light to off.
+8. Drive forward in a straight line for 0.5 rotations.
+
+```blocks
+brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
+    motors.largeBC.steer(0, 50, 3, MoveUnit.Rotations)
+    pause(1000)
+    brick.setStatusLight(StatusLight.OrangeFlash)

+```
+
+### Download and test
+
+Click Download and follow the instructions to get your code onto your EV3 Brick. Press the center button on the EV3 Brick to run the program.
+
+### Share
+
+**Think about:**
+
+* What challenged you?
+* Were there any surprises?
+* How can you improve your program?
+* Can your program be more streamlined? Have you used too many blocks?
+* Is there a more efficient way to build your program?
+* How can your program be used in real-world scenarios?
+
+## Continue
+
+* Click on the JavaScript tab and experiment with changing the values in the code.
+* Add a custom image or sounds from the Brick or Music menus.
+* Create a video of your project, especially your final presentation and your robot’s performance. Explain some important features of your software program. 
+* Include an image of your program with comments. 
+* Add a team photograph! 
+
+Congratulations! What will you design next?

+# Line Detection
+
+Design ways to improve driving safety by helping to prevent drivers from falling asleep and causing an accident.
+
+![Car following the line on the road](/static/coding/line-detection/car-road-line.jpg)
+
+## Connect
+
+Think about:
+
+* How can autonomous cars react to different traffic light signals?
+* What can happen if a driver falls asleep while driving?
+* How can we detect when a driver is falling asleep?
+
+## Construct
+
+### Build
+
+Build a @boardname@ vehicle that can help prevent drivers from falling asleep and causing an accident. Start by constructing this model:

+
+### Check
+
+Before you program, check:
+
+* Are all the wires correctly connected from the motors to ports B and C?
+* Are the wheels correctly installed?
+* Are the wheels rotating freely?
+* Are the wires connected from the Color Sensor to port 3?
+
+![EV3 Driving Base](/static/coding/line-detection/ev3-robot-driving-base.jpg)
+
+### Program
+
+Autonomous cars need to recognize and respond to traffic lights automatically. Create a program that will make your robot stop at red lights. Make sure your robot is only responding to the color red. Once you have succeeded, program your robot to drive forward again when the light changes from red to green.
+
+Before you program, think about:
+
+* How will you program the robot to detect a color?
+* How will you program the robot to stop at a color?
+* Which programming blocks will you use?
+
+### ~ hint
+
+Consider using these blocks in your solution:
+
+```block
+loops.forever(function () {
+	
+})
+motors.largeBC.steer(0, 50)
+sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
+motors.stopAll()
+```
+
+### ~
+
+### Sample Solution - Red light detection
+
+1. Loop forever.
+2. Start motors ``B`` and ``C`` (drive forward).
+3. Wait for the color sensor to detect the color red.
+4. Stop all motors.
+
+```blocks
+loops.forever(function () {
+    motors.largeBC.steer(0, 50)
+    sensors.color3.pauseUntilColorDetected(ColorSensorColor.Red)
+    motors.stopAll()
+})
+```
+
+### Download and test
+
+Click **Download** and follow the instructions to get your code onto your EV3 Brick. 
+
+Congratulations! Your robot can stop at a red light. 
+
+Now add to your program and have your robot to drive forward again when the light changes from red to green.
+
+### Sample Solution - Red and green light detection in a loop
+
+1. Start motors ``B`` and ``C`` (drive forward).
+2. Wait for the color sensor to detect the color red.
+3. Stop all motors.
+4. Wait for the color sensor to detect the color green.
+5. Loop forever.
+

+})
+```

+
+Click **Download** and follow the instructions to get your code onto your EV3 Brick. 
+
+## Contemplate
+
+To simulate what could happen if a driver falls asleep while driving, your robot could sound an alarm signal when it crosses the line. This feature is often available in new cars.
+
+Program your robot to perform this function.
+
+Draw a dark line with tape or marker for your robot to cross.
+

+```
+### ~
+
+### Sample Solution - Line detection in a loop
+
+1. Start motors ``B`` and ``C`` (drive forward with a curve toward the line).
+2. Wait for the color sensor to detect the color black.
+3. Play sound effect ``system general alert``.
+4. Start motors ``B`` and ``C`` (drive forward with a curve away from the line).
+5. Wait for the color sensor to detect the color white.
+6. Loop forever.
+
+```blocks

+
+#### Differentiation
+
+Program your robot to drive on “autopilot” along a given route. You will need to create a program that recognizes and responds to a dark line (or white line). You will create a line-following program and your robot will need to travel along the line without losing contact with it.
+
+You will need to constantly debug your program in order to make your robot travel as smoothly as possible along the line.

+### ~
+
+### Sample Solutions - Line Following in Loop
+
+#### Method 1
+
+1. While the Color Sensor detects the color black, start motors ``B`` and ``C`` (drive forward with a curve toward the line).
+2. While the Color Sensor detects the color white, start motors ``B`` and ``C`` (drive forward with a curve away from the line).
+3. Loop forever.

+
+#### Method 2
+
+1. If the Color Sensor detects the color black, start motors ``B`` and ``C`` (drive forward with a curve toward the line).

 ## Connect
 
 ### Design Brief
 
-Design, build and program a robot that can move itself a distance of at least 30cm, using at least one motor, using NO wheels for locomotion.
+Design, build and program a robot that can move itself using no wheels for locomotion.
+
+![Make it move banner](/static/lessons/make-it-move/make-it-move-without-wheels.png)
+
+Your robot will:
+
+* Go a distance of at least 30cm
+* Use at least one motor
+* Use NO wheels for locomotion
 
 ### Brainstorm
 
-Discuss different solutions to the design brief.
-
-Think about:
-
-How can robots move without wheels? For example, how will you:
-* Connect the motor(s) to something to make the robot walk, crawl, or wiggle?
-How will you program the robot to move? For example, which programming blocks will you use to:
-* Turn on and turn off the motor or motors?
-* Display the distance moved?
-
-### Select the Best Solution
-
-Describe the solution that you have agreed to build and program.
-
-Think about examples from your brainstorming discussion. Then explain why you chose this solution for the design brief.

+In nature, creatures use many methods to get around. None of them, however, use wheels to move. Can we copy the method of animal locomotion with our robot? Using motors and legs, make a robot that can move without using any wheels.
 
 ## Construct
 
-### Build and Program
+### Build
 
-Now you are ready to start building and programming your solution!
+Think about a creature’s movement for inspiration. Will you make the robot walk, crawl, hop, or wiggle?  Your mechanism can be attached or unattached to the EV3 brick. You can start by tinkering with the LEGO elements in the picture above and then build on.
+
+### Building Hint
+
+If you want some building help you can follow these instructions.
+
+[![Toddle Bot](/static/lessons/make-it-move/toddle-bot.jpg)](https://le-www-live-s.legocdn.com/sc/media/files/support/mindstorms%20ev3/building-instructions/design%20engineering%20projects/toddle%20bot-3dcad146d7f5deac4753f93e9dcc0739.pdf)
+
+### Program
+
+Before you program, think about:
+
+* How will you program the robot to move? 
+* How will you program the robot to stop?
+* How will you program the robot to display the distance moved?
+
+Which programming blocks will you use:
+
+* To turn on and turn off the motor or motors? 
+* To display the distance moved? 
+
+### Sample Code
+
+Example code of a robot that moves without wheels using one motor:
+
+* The robot moves with ``large motor D`` rotating at ``-100`` speed
+* The robot moves for ``30000`` milliseconds (30 seconds)
+* The robot stops 
+* The robot displays the text ``"30cm"``
 
 ```blocks
-motors.largeBC.tank(-60, 60, 9, MoveUnit.Rotations);
-motors.stopAll();
+brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
+    motors.largeD.run(-100)
+    loops.pause(30000)
+    motors.stopAll()
+    brick.showString("30cm", 1)
+})
 ```
 
-As you work on your solution:
+### Download and test
 
-* Describe one part of your design that worked especially well.
-* Describe one design change that you had to make.
-
-What will you try next?
-	
-As you test your design solution, use the table for recording your findings.
-
-[**VIEW BUILDING INSTRUCTIONS**](TODO) for a sample solution. (7.8 MB, PDF)
+Click **Download** and follow the instructions to get your code onto your EV3 Brick. Press the center button on the EV3 Brick to run the program.
 
 ## Contemplate 
 
 ### Test and Analyze
 
-How well does your solution satisfy the design brief? Record your data. Name the columns and rows, such as Trial Number, Distance Moved, and Observations.
-
-### Review and Revise
-
-Take a moment to reflect on your robot solution.
-
 Think about:
+
 * Is the robot using something other than wheels to move? Trace the movement from the motor axle to the mechanism(s) that drives the robot forward, backward or sideways. Wheels can be used to stabilize the robot but not to drive it.
-* Does the robot display the distance moved?
-* Is it accurate? How do you know?
-Describe two ways you could improve your robot.
+* Does the robot display the distance moved? Is it accurate? How do you know?
+* What is one part of your design that worked well?
+* What is a change that you need to make?
+* What will you try next?
 
 ## Continue
 
-### Communicate
+### Personalize your project
+
+* Add/remove LEGO elements to improve the way your robot moves. Will your robot walk, wiggle, hop, or slither? Will it move slower, faster or farther?
+* Click on the JavaScript tab and experiment with changing the values in the code.
+* Add a custom image or sounds by adding blocks from the Brick or Music menus.
+* Does your robot resemble a creature? Add arts and crafts materials to your project.
+
+## Communicate
 
-Here are some ideas:
 * Create a video of your project, especially your final presentation and your robot’s performance.
 * Explain some important features of your software program.
 * Produce a building guide for your model by taking a series of photographs as you deconstruct it.
 * Include an image of your program with comments.
 * Add a team photograph!

+Now we will try to control the Large Motor using another sensor.
+
+![Hand connecting Color Sensor to Port 4, Large Motor D, EV3 Brick](/static/getting-started/12_ConnectColor.png)
+
+Keeping the Large Motor connected to **Port D**, connect the Color Sensor to **Port 4**.
+
+**Code it:** Modify Your Program to use the Color Sensor.
+
+```blocks
+brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
+    sensors.color3.pauseUntilColorDetected(ColorSensorColor.Green)
+    motors.largeD.run(50, 1, MoveUnit.Rotations)
+})
+```
+
+* Using the same program, replace the ``||sensors:pause until touch 1||`` block with a ``||sensors:pause color sensor 3||`` for color block.
+
+```block
+sensors.color3.pauseUntilColorDetected(ColorSensorColor.Green)
+```
+
+* Select the color you want to detect (e.g., green).
+
+**Download:** Click **Download** and follow the instructions to get your code onto your EV3 Brick. Press the center button on the EV3 Brick to run the program.
+
+## Place a Colored Brick in Front of the Color Sensor
+
+![IMG: Colored bricks in front of Color Sensor, hands, EV3 Brick](/static/getting-started/14_ColorSensorWorking.png)
+
+Confirm that the Large Motor has turned one rotation AFTER the Color Sensor has detected the colored brick.
+
+Download and run the program as many times as you want in order to verify this, or tinker with different Color Sensor and Large Motor values.
+
+Click on the **JavaScript** tab and change the color the Color Sensor detects to Black, Blue, Green, Yellow, Red, White, or Brown. Use Title Case for the color names.
+
+## Well Done!
+
+You have now learned how to control some of the inputs and outputs of the EV3.

+![EV3 Driving Base full w/cuboid](/static/getting-started/EV3_GettingStarted_13.jpg)
+
+In this project we will guide you through building a Driving Base Robot and programming it to move straight and turn. You will also build and Object Detector Module, and program it to detect an object. It’s a good idea to have done the [Try](/getting-started/try) sequence first.

+
+## Make It Move
+
+**Code it:** Create a program that makes the Driving Base move forward and stop at the finish line, which is ``1`` meter away.
+
+Start by building this program:
+
+```blocks
+brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
+    motors.largeBC.steer(0, 50, 1, MoveUnit.Rotations)
+})
+```
+
+* Drag a ``||motors:steer large motors B+C||`` block inside an ``||brick:on button||`` block.
+* Click on the **(+)** sign.
+* Change to ``1`` rotation.
+
+### ~hint
+
+**Hint:** You will have to modify the number of rotations until you find the number that matches the robot moving forward 1 meter and stopping.
+
+### ~
+
+**Download:** Click **Download** and follow the instructions to get your code onto your EV3 Brick. Press the center button on the EV3 Brick to run the program.
+
+## Make It Turn
+
+**Code it:** Create a new program that turns the Driving Base 180 degrees.
+
+```blocks
+brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
+    motors.largeBC.steer(-50, 50, 1, MoveUnit.Rotations)
+})
+```
+
+### ~hint
+
+**Hint:** You will have to modify the turn ratio and the number of rotations until the robot reaches 180 degrees.
+
+### ~
+
+**Download:** Click **Download** and follow the instructions to get your code onto your EV3 Brick. Press the center button on the EV3 Brick to run the program.
+
+## Add an Ultrasonic Sensor to Your Driving Base
+
+Build and attach an Ultrasonic Sensor to your driving base:
+
+[![EV3 Ultrasonic Sensor Driving Base Building Instructions Main Image](/static/lessons/common/ev3-ultrasonic-sensor-driving-base.jpg)](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-ultrasonic-sensor-driving-base-61ffdfa461aee2470b8ddbeab16e2070.pdf)
+
+## Detect an Object
+
+**Code it:**  Create a program that moves the Driving Base and makes it stop ``6`` cm from the Cuboid.
+
+Create a new program:
+
+```blocks
+brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
+    motors.largeBC.tank(50, 50)
+    sensors.ultrasonic4.setThreshold(UltrasonicSensorEvent.ObjectDetected, 6)
+    sensors.ultrasonic4.pauseUntil(UltrasonicSensorEvent.ObjectDetected);
+    motors.stopAll()
+})
+```
+
+* Drag a ``||motors:tank large motors B+C||`` motor block inside the ``||brick:on button||`` block.
+* Drag the Ultrasonic Sensor threshold ``||sensors:set ultrasonic 4||``  block and place it below the motor block.
+* Drag a ``|sensors:pause until ultrasonic 4||`` block and place it under the threshold block.
+* Drag a ``||motors:stop all motors||`` block and place it below the sensor block.
+
+### ~hint
+
+**Hint:** You will have to modify the values of the Ultrasonic Sensor block until the robot reaches the desired position.
+
+### ~
+
+**Download:** Click **Download** and follow the instructions to get your code onto your EV3 Brick. Press the center button on the EV3 Brick to run the program.
+
+Click on the **JavaScript** tab. Change and test the number value of the Ultrasonic
+Sensor.
+
+```typescript
+sensors.ultrasonic4.setThreshold(UltrasonicSensorEvent.ObjectDetected, 10)
+```
+
+**Congratulations!**
+
+You are ready to move on to the next steps.

+2. Pick one problem and explain it to a partner.
+
+### Brainstorm
+
+Now that you have defined a problem, start to generate ideas for solving it. 
+
+### ~hint
+
+Some things to do while brainstorming:
+
+* Use the bricks from the LEGO set to help you brainstorm or sketch your ideas on paper.
+* The goal of brainstorming is to explore as many solutions as possible. You can use the tinkering examples in the Sample Solutions section below as inspiration for getting started.
+* Share your ideas and get some feedback. It may lead to more ideas!
+
+### ~ 
+
+### Define the Design Criteria
+
+1. You should have generated a number of ideas. Now select the best one to make. 
+2. Write out two or three specific design criteria your design must meet.
+
+### Go Make
+
+It is time to start making!
+
+* Use the components from the @boardname@ Core Set and additional materials to make your chosen solution. 
+* Test and analyze your design as you go and record any improvements that you make. 
+
+### Review and Revise Your Solution
+
+* Have you managed to solve the problem that you defined? 
+* Look back at your design criteria. How well does your solution work? 
+* How can you improve your design?
+
+### Communicate Your Solution
+
+Now that you have finished you can:
+
+* Make a sketch or take a photo or video of your model.

+### Defining the Problem
+
+1. What problems did you imagine? 
+2. Pick one problem and explain it to a partner.
+
+### Brainstorm
+
+Now that you have defined a problem, start to generate ideas for solving it. 
+
+### ~hint
+
+Some things to do while brainstorming:
+
+* Use the bricks from the LEGO set to help you brainstorm or sketch your ideas on paper.
+* The goal of brainstorming is to explore as many solutions as possible. You can use the tinkering examples in the Sample Solutions section below as inspiration for getting started.
+* Share your ideas and get some feedback. It may lead to more ideas!
+
+### ~
+
+### Define the Design Criteria
+
+* You should have generated a number of ideas. Now select the best one to make. 
+* Write out two or three specific design criteria your design must meet.
+
+### Go Make
+
+It is time to start making!
+
+* Use the components from the @boardname@ Core Set and additional materials to make your chosen solution. 
+* Test and analyze your design as you go and record any improvements that you make. 
+
+### Review and Revise Your Solution
+
+* Have you managed to solve the problem that you defined? 
+* Look back at your design criteria. How well does your solution work? 
+* How can you improve your design?
+
+### Communicate Your Solution
+
+Now that you have finished you can:
+* Make a sketch or take a photo or video of your model.
+* Label the three most important parts and explain how they work.
+* Share your work with others.

-Get the current number of degress of rotation.
-
-```sig
-motors.largeA.tacho()
-```
-
-The motors that come with your @boardname@ have a way to detect their own turning motion. They count the amount of motor rotation in degrees. The motor will count each degree of angle rotation up to 360 degrees for a full rotation. As the motor continues to turn, the _tacho_ count keeps adding up the degrees even past one full rotation. So, if the motor makes 3 complete rotations, the count will be 1080.
-
-The name _tacho_ comes from the first part of the word [tachometer](https://en.wikipedia.org/wiki/Tachometer) which is a device to measure how fast something is turning. The motor controller in the brick uses the tacho count to regulate the motor's speed.
-
-## ~hint
-
-**Measure RPM**
-
-A standard way to know how fast a motor is turning is by measuring its _revolutions per minute_ (rpm). One revolution is the same thing as a rotation, or one turn. How do you measure rpm? Well, here's a simple way:
-
-1. Record the current tacho count
-2. Run the motor for 60 seconds
-3. Get the tacho count again
-4. Subtract the first tacho count from the second one
-5. Divide that number by `360`
-
-## ~
-
-## Returns
-
-* a [number](/types/number) which is the total count of degrees of rotation that the motor has turned since it was first started or reset.
-
-## Example
-
-Run the motor connected to port **A** at half speed for 5 seconds. Display the number of full rotations on the screen.

-```blocks

To make a fast, or sharp, turn to the right, the left motor could run at least twice as fast as the right one.
