# Make It Smarter and Faster

### Design Brief
|
||||
|
||||
Design, build and program a robotic creature that can sense its environment and respond by moving.
|
||||
|
||||
https://www.youtube.com/watch?v=y9-A_C_08KY
|
||||
|
||||
* What do the robots in the video need to be able to sense, plan, and act?
|
||||
* What senses do humans have and why are they important to us?
|
||||
* How many human-like senses do you see the robots demonstrating?
|
||||
|
||||
### Brainstorm
|
||||
|
||||
Discuss different solutions to the design brief.
|
||||
|
||||
Think about:
|
||||
|
||||
* What kind of creature can it be?
|
||||
* How can it move?
|
||||
* What does it need to be aware so that it stays safe, well fed and warm (or cool)?
|
||||
* Is it looking for food, a safe place to hide or a warm place to soak up the sun?
|
||||
* Will the creature need to move fast or slow?
|
||||
* Will it need to turn?
|
||||
* Will it need to go backward?

## Construct
|
||||
|
||||
### Build
|
||||
|
||||
Think about a creature’s movement for inspiration. Your mechanism can be attached or unattached to the EV3 brick. You can start by tinkering with the LEGO elements in the picture add then build on.

### Program
|
||||
|
||||
Before you program, think about:
|
||||
|
||||
* How will you program the robot to sense?
|
||||
* How will you program the robot to respond?
|
||||
* Which programming blocks will you use?
|
||||
|
||||
### ~ hint
|
||||
|
||||
**Hint:** Explore the different Sensor blocks in the Sensors Menu

Sample Solution
|
||||
|
||||
[Video: EV3 Insect]
|
||||
|
||||
This Insect uses its Ultrasonic Sensor to sense danger and move away from threat.
|
||||
|
||||
The Insect solution combines these building ideas:
|
||||
|
||||
* EV3 Frames
|
||||
* Leg 2
|
||||
* Leg 3
|
||||
* Ultrasonic Sensor
|
||||
|
||||
Four copies of Leg 3 were built: one for the front left, one for the back right, and two mirror copies for the front right and back left.
|
||||
|
||||
* [Building Instructions](https://le-www-live-s.legocdn.com/sc/media/files/support/mindstorms%20ev3/building-instructions/design%20engineering%20projects/insect-94b8a46f0dc5082c9d78ddb734626dc9.pdf)
|
||||
|
||||
### Sample Solution
|
||||
|
||||
This program checks if the Ultrasonic Sensor senses something near.
|
||||
|
||||
This program:
|
||||
|
||||
* Turns on the green EV3 brick Status Light
|
||||
|
||||
```block
|
||||
brick.setStatusLight(StatusLight.Green)
|
||||
```
|
||||
|
||||
* Waits for Ultrasonic Sensor to detect an object
|
||||
|
||||
```block
|
||||
sensors.ultrasonic4.pauseUntil(UltrasonicSensorEvent.ObjectDetected)
|
||||
```
|
||||
|
||||
* Turns on Motors A and D in opposite directions
|
||||
|
||||
```block
|
||||
motors.largeAD.tank(50, -50)
|
||||
```
|
||||
|
||||
* Waits for one half of a second (1500 milli seconds)
|
||||
|
||||
```block
|
||||
pause(1500)
|
||||
```
|
||||
|
||||
* Reverses the direction of Motors A and D
|
||||
|
||||
```block
|
||||
motors.largeAD.tank(-50, 50)
|
||||
```
|
||||
|
||||
* Waits for one half of a second
|
||||
* Stops all motors
|
||||
|
||||
```block
|
||||
motors.stopAll()
|
||||
```
|
||||
|
||||
* Makes an insect chirping sound
|
||||
|
||||
```block
|
||||
music.playSoundEffectUntilDone(sounds.animalsInsectChirp)
|
||||
```
|
||||
|
||||
* Loops so the insect wanders around when the Ultrasonic Sensor is triggered
|
||||
|
||||
```blocks
|
||||
forever(function () {
|
||||
brick.setStatusLight(StatusLight.Green)
|
||||
sensors.ultrasonic4.pauseUntil(UltrasonicSensorEvent.ObjectDetected)
|
||||
motors.largeAD.tank(50, -50)
|
||||
pause(1500)
|
||||
motors.largeAD.tank(-50, 50)
|
||||
pause(1500)
|
||||
motors.stopAll()
|
||||
music.playSoundEffectUntilDone(sounds.animalsInsectChirp)
|
||||
})
|
||||
```
|
||||
|
||||
### 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
|
||||
|
||||
### Test and Analyze
|
||||
|
||||
As you work on your solution:
|
||||
1. Describe one part of your design that worked especially well.
|
||||
2. Describe one design change that you had to make.
|
||||
3. What will you try next?
|
||||
|
||||
|
||||
### Review and Revise
|
||||
|
||||
Take a moment to reflect on your robot solution.
|
||||
|
||||
Think about:
|
||||
|
||||
* Does your robot move when the sensor is activated?
|
||||
* If not, what will you change to make the robot’s ability to sense and respond more obvious?
|
||||
* What other behaviors can you add to the robot to make it more realistic?
|
||||
|
||||
Describe two ways you could improve your robot.
|
||||
|
||||
|
||||
## Continue
|
||||
|
||||
Personalize your project
|
||||
|
||||
* Add/remove LEGO elements to improve the way your robot moves.
|
||||
* 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 you 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!
|
||||
|
||||
Congratulations! What will you design next?
