-other students build spacemat models, building instructions at bottom of
link below.
Practice using EV3 software on Macbooks. All in-person students must show that they can program their EV3 to go in a square.
Additional challenges: Follow tutorials in Mindstorms EV3 using the Ultrasonic and color sensors: "Stop at Object", and "Stop at Line"

Homework: Answer questions on googledoc and be prepared to discuss in class next week.

Today we will share our walking robots.
This week you will design, build, and program a robot that draws a pattern, performs the task accurately, and is able to repeat the task.
Think about:
What kind of motorized mechanism holds a pen or pencil?
What kind of motorized mechanism can move the pen into more than two locations?
How can the robot’s movements be accurate and repeatable?

Before class next week, upload a video of your robot drawing a pattern. I will share the videos during class.

Today we'll share our results of trying to make a robot move without wheels.
This week you'll follow one of the building instructions below to help you make a walking robot. Be prepared to share your robot during class next week.

Design, build and program a robot that moves 1 meter on a level surface without wheels of any kind. It can hobble, crawl, wiggle or flip, but it cannot use anything that resembles wheels (no using tracks or gears as wheels).
Watch the TedTalk video for examples of how robots can move without wheels.
Use at least one motor.
Be prepared to show your robot during class next week or share a video of it on the class google slideshow.
Complete the analysis sheet.

Design, build, and program a robot that can move up the steepest incline possible.
Week1- Design, build and program your first design, record results and be prepared to share robot in class.
Week2- Improve on your design and programming. be prepared to share final results and robot build in class.

Materials:
-EV3 kit
-You’ll need a one meter-long BOARD or foam board to construct the ramp; and books, blocks, or other objects to adjust the incline.
-Use a PROTRACTOR to measure the incline in degrees, or a measuring tape to measure the incline by rise over run.

-Design, build, and program a robot that can move up the steepest slope possible.
-Create an incline using a board that is about 1 meter in length. Prop one end of the board up on a stack of books or a chair.
-Drive the robot up the full length of the board
-Increase the incline on the slope until the robot can no longer drive all the way up.
-Record the angle of the incline in degrees by using a protractor or by using a measuring tape to measure the incline by rise over run.

Challenge:
-Design, Build, and program something using the bevel gears.
-It can be an attachment, like a claw or you can use the building instructions to create a vehicle.
-We will share our builds during class

Teacher-Classwork
Discuss last week's homework, Gears:
-each student briefly shares the 5th gear configuration they made.

What happens to the turning direction when two gears are meshed together? 3 gears?
How’s the gear ratio related to the number of teeth on the gears?

Start new discussion on shifting gears:
-In which situation is it useful to shift gears up or down?
-It’s difficult to travel uphill or against the wind on a bike. A good gear system is useful in adjusting the power needed to keep moving. When traveling across level ground, you start off in a low gear and then shift into higher gears at higher speeds.

Homework:
This week you will build and program a geared vehicle.
-Follow the building instructions to create your geared vehicle (you do not need to attach the ultrasonic sensor)
-watch the video to understand how to program and run your experiment
-perform the experiment at least 2 times for each of the suggested gear trains (different gear trains are shown at the end of the building instructions).
-record the average result for each gear train in the table on your analysis sheet.
- analyze how gear ratio relates to the distance traveled and velocity of the vehicle.

Today we will discuss how our obstacle course project is going, and help each other troubleshoot problems.

If you completed and shared your project last semester, you have no homework, but those of you who didn't complete it need to be finished and prepared to share next week.

If you are finished, you may free-build and explore this week, and then take apart your robot, putting pieces where they belong in your kit. We will be starting from scratch next week, learning engineering design basics, starting with gears.

Hopefully now everyone has a basic understanding of how to program the EV3 to drive, turn, and react to sensors. Next, you are going to create a maze/obstacle course for your EV3.
First week, you will create a maze and program your EV3 to stay on course using the color or ultrasonic sensor. Second week, you will learn to create an attachment using the medium motor that is capable of moving objects. Third and fourth week, you will add obstacles to your maze that must be moved using an attachment you created and programmed. You could choose a fun theme, like "Jurassic Park" or "Mars Station".

If you are new to robotics, please keep it very simple and only use 2 sensors (one controls the steering motors, one controlling the attachment). Only add more sensors if you know how to program multiple sensors controlling the same motor.

GOOGLE SLIDESHOW - Each week, add a video or picture of your progress to the slideshow. We will discuss our progress and troubleshoot problems during class. You may also help other students troubleshoot during the week. All of Tues, Thurs, and Friday students will share a slideshow and may help each other.

Week 1
-Create a base for your maze using 2 sheets of 22"x28" posterboard taped together for a total size of 44"x28".
-Create a maze using black electoral tape or blue painter's tape. Or it could have a dark background with white tape. Keep the maze fairly simple because you will be adding obstacles later. As an alternative, you could build walls and use the ultrasonic sensor.
-Create a theme for your course. (Minecraft, City Streets, Alien World, Dog Park, Football, etc)
-Program your EV3 to navigate the maze using the color sensor.
-- post picture of your maze on posterboard, or video of ev3 completing maze.

Week 2
-Build an attachment for your driving base that can move an object. Building instructions for a gripper or a cargo arm are below.
-Practice programming your attachment using an additional sensor that detects the object.

Weeks 3 and 4
-Continue to make your maze more complicated by adding obstacles that must be moved using the the attachment.
-Create "rooms" where the obstacles need to be moved to.
- Program your EV3 to navigate the course.

1. Follow the second half of the "Use" tutorial: Add Ultrasonic Sensor to Your Driving Base; and Detect an Object. Download the program to your EV3. Try programming the EV3 to stop when it detects an object less than 10 cm. away. Then try to create a program in a loop that will drive until it detects an object, back up a little, then turn and keep driving until it detects another object. Watch the ultrasonic video below for a demonstration.
2. Review the color sensor tutorials you did with the virtual simulation in makecode, and experiment with running those programs on your EV3.
3. Program your EV3 to follow a line and create a line for it to follow. Black electrical tape works best, or you can use blue tape on the floor or a large piece of cardboard. It works best if you have high contrast between the line and the floor. Watch the video below to see how I adjusted the light intensity value in my program to work for different surfaces. I also show how I use the port view on the EV3 display to determine what value the color sensor is detecting.
4. Record a video of your EV3 completing the line-following challenge and add your video to the Line Following slideshow before class starts next week.

This week you will follow the tutorial in makecode to build a driving base, then program your robot to drive straight and turn. You will try your first challenge- driving your robot in a square.

1-Complete the first 3 sections of the "Use" tutorial: Build driving base; Make it move; Make it turn.
2-Watch the video showing the Baseball challenge.
3-Look at the baseball challenge PDF
4-Complete the baseball challenge activity sheet and submit

This week you will do the following to begin learning how to use your EV3 robotic kit:
-watch unboxing video and complete googleform posted last week.
-pick up EV3 kit from Apex
-organize your kit pieces and UPLOAD A PHOTO OF YOUR ORGANIZED KIT HERE IN GOOGLE CLASSROOMS.
-in makecode.mindstorms.com, complete the tutorial under "getting started" -"try" (link below) Here you will learn to download programs onto your brick and connect/program your sensors. If you have trouble completing the tutorial, go to "TROUBLESHOOTING" in the left-hand column of the tutorial.

We are continuing to learn about robots in action. This week we will watch a video and complete the google doc, answering questions about how robots are used in production and in safety and security applications.
For your homework, finish answering the questions and turn them in.
Also, fill out the form in EV3 kits titled "Lego EV3 Check-out guidelines"

Production Robots:
Robots are used to assemble, disassemble and form materials to create usable products.


Safety and Security Robots:
Robots move in hazardous places and monitor vehicles, homes and other environments for dangerous conditions.

Watch this video showing examples of medical and personal robots and then answer the questions on the google doc

Note: we will not be downloading the programs to the bricks at this point, Just use the simulator to see how it works.
Over the next few weeks we will be completing the motor tutorial, the touch sensor tutorial, the color sensor tutorial, ultrasonic sensor tutorial, and the gyro tutorial.

This week we are looking at the role robots play in fiction and how robots have developed over time.

1. View list of fictional robots. This list of fictional robots and androids is chronological, and categorized by medium. It includes all depictions of robots and androids in literature, television, and cinema; however, robots that have appeared in more than one form of media are not necessarily listed in each of those media. It shows how the concept has developed in the human imagination through history.
3.Complete the Robot in Fiction worksheet.

Answer the questions and turn in before class next week.

We will do this together during class today.

Draw a robot and label its parts. Describe it's function. Be prepared to share your drawing in class next week.
