Everyday Robots

• Robots are a part of everyday life.• Components of robotics such as sensors are in

many devices we use daily. – Ex: motion sensors are used to open automatic

doors.• Used by most people daily to offer

convenience and security.

Step 4: The WeDo Introduction

What is a WeDo?

• WeDo is a LEGO product that allows elementary aged youth to build robots using LEGO pieces.

• Robots are connected to a computer and programmed to perform specific functions using the WeDo software.

• Each individual kit has plans for 12 different LEGO robots.•More building resources

are available through LEGO.

What Do WeDo Robots Look Like?

The Finished Alligator

The Check List• Is the gear is facing the correct direction?• Are rubber bands connected securely?• Is the motion sensor lined correctly?• Does the mouth open and close? Test Gear.• Are sensors securely attached to the USB Hub?• Are all LEGO bricks attached securely?• Look over entire build and make sure it is identical

to the guide.

Step 6: The WeDo Activity Pack

• Curriculum• Add-on Software• Provides step-by-step on-

screen instructions in building and programming

• Classroom type activities and handout materials are provided for each build

Review the Activity Pack

• Page 80 – Objectives• Page 81 – Animated Movie and Discussion

Questions• Page 82 – Construct, overview of mechanisms

and process• Page 83 – Basic Functions of software• Page 84-86 – Lesson Plan

Step 7: Programming with the WeDo Software

• Demonstration Video (add link)• Alligator Build – stop animation movie

showing the alligator build itself– Click on the link above to launch movie (note:

movie must be embedded on cd with ppt. to launch.)

• Self Demonstration• Continue to ….(add link to page in ppt)

WeDo Software Introduction

• Drag and drop icon based software • Provides an intuitive and easy to use ‐ ‐

programming environment• Software automatically detects motors and

sensors when they are attached to the LEGO USB Hub

• Includes a Getting Started Guide with simple building tips and programming examples

On Screen Building Instructions

Start Programming

• Plug in robot by connecting the USB to the computer

• Sensor icon should appear in upper left hand corner (insert pict. Of sensor)

Experiment with the Programming

• Experiment with the program by adding additional icons such as sound, backgrounds, text or change the motor directions.

Programming Discussion

• What was a challenge you encountered while building?

• Where there any challenges using the software?

• Was this easier or harder than you thought it would be? Explain.

Youth Development Adaptations

Consider the following skills that can be developed through WeDo projects and the Activity Pack projects • Youth are encouraged to use creativity, teamwork and

problem solving = life skills!• Youth develop language and literacy through narrative and

journalistic writing, storytelling, explaining, interviewing and interpreting

• Youth experience mathematics when measuring time and distance; adding, subtracting, multiplying, dividing, estimating, and using variables.

Youth Development Adaptations

Consider the following skills that can be developed through WeDo projects and the Activity Pack projects • Youth experience science through working with simple

machines, gears, levers, pulleys; and experimenting with transmission of motion

• Youth discover technology when programming; using software media; and designing and creating a working model.

Youth Development Adaptations

• How could youth use WeDo robots to perform service learning? – (ex: providing a WeDo workshop for 4-H members)

• How could a club use WeDo kits as a fundraiser?• How could a 4-H member use a WeDo kit in a

traditional 4-H activity, such as a county fair or communications contest?

• How could a teen leader use WeDo kits to do an activity with junior members?
