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.
What Do WeDo Robots Look Like?
• Each individual kit has
plans for 12 different
LEGO robots.
• More building resources
are available through
LEGO.

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

• 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.

mentors.
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?
