+# Autonomous Parking
+
+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 LEGO MINDSTORMS vehicle that can park itself safely without driver intervention.
+Start by constructing this [model](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-rem-driving-base-79bebfc16bd491186ea9c9069842155e.pdf).
+
+![EV3- Robot Driving Base](/static/coding/autonomous-parking/ev3-robot-driving-base.jpg)
+
+### Checks
+
+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)
+    motors.largeBC.tank(50, 50)
+    loops.pause(3000)
+})
+```
+### 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.
+
+## Contemplate
+
+Choose one of the following autonomous driving scenarios and create a program for it:
+
+* 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.
+
+```blocks
+brick.buttonEnter.onEvent(ButtonEvent.Pressed, function () {
+    motors.largeBC.steer(0, 50, 3, MoveUnit.Rotations)
+    pause(1000)
+motors.largeBC.steer(-50, -50, 1.5, MoveUnit.Rotations)
+    motors.largeBC.steer(50, -50, 1.5, MoveUnit.Rotations)
+    motors.largeBC.steer(0, -50, 0.5, MoveUnit.Rotations)
+    motors.largeBC.steer(0, 50, 0.5, MoveUnit.Rotations)
+})
+```
+
+### 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.
+
+### Differentiation
+
+Create a program that simulates displaying appropriate warning lights while parking. 
+
+### ~hint
+
+Consider using this block in your solution:
+
+```block
+brick.setStatusLight(StatusLight.OrangeFlash)
+```
+
+### ~
+
+### Sample Solution - Simulating Reverse Gear and Reverse Warning Lights
+
+1. When the brick button is pressed, drive forward in a straight line for 3 rotations.
+2. Wait for 1 second.
+3. Set brick status light to orange flash.
+4. Reverse motor rotation while turning for 1.5 rotations.
+5. Reverse motor rotation while turning the other way for 1.5 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)
+    motors.largeBC.steer(-50, -50, 1.5, MoveUnit.Rotations)
+    motors.largeBC.steer(50, -50, 1.5, MoveUnit.Rotations)
+    motors.largeBC.steer(0, -50, 0.5, MoveUnit.Rotations)
+    brick.setStatusLight(StatusLight.Off)
+    motors.largeBC.steer(0, 50, 0.5, MoveUnit.Rotations)
+})
+```

+### 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?
