EV3 LEGO Robotics:
Basic Building and Programming
Welcome to the BCPS
FIRST LEGO League Training
• Check In
• Pick up your materials
• Unpack your Robotics Core Set and locate the
battery and charger
• Plug in the battery (so we can make some cool
robots drive around the room later today)
• Unpack the robot parts and divide up into the sorting
tray. *Sorting Sheet available at the desk for the EV3. NXT guide is
on the back of the lid insert.

• Describe what will be gained by coaching a team
FIRST Lego League (FLL)
• Explain the 3 parts of the FLL Challenge
• Construct a plan with initial steps to launch a FLL team at their site
• Know where to find critical information regarding FLL materials on the
Internet

Building
• Identify the main LEGO EV3 components and explain how they are used
• Build a basic Robot from pictorial directions
Programming
• Navigate the EV3 Software components
• Write a basic program that has robot drive forward, backwards, turn and
adjust speed
• Write an advanced program using a 3rd motor with attachment
What is FIRST LEGO League?
FLL introduces younger students to real-world engineering challenges by building LEGObased robots to complete tasks on a thematic playing surface. FLL teams, guided by their
imaginations and adult coaches, discover exciting career possibilities and, through the
process, learn to make positive contributions to society.
• Design, build, and program robots using LEGO MINDSTORMS®
technology
• Apply real-world math and science concepts
• Research challenges facing today’s scientists
• Learn critical thinking, team-building, and presentation skills
• Participate in tournaments and celebrations
What FLL teams accomplish is nothing short of amazing. It’s fun. It’s
exciting. And the skills they learn will last a lifetime.
From the US FIRST FLL website
Gracious Professionalism ™
You are “Gracious Professionals.” You are competing hard against
PROBLEMS, while treating PEOPLE with respect and kindness - people from
your own team as well people from other teams.
You build onto other people’s ideas instead of resisting or defeating them.
Coopertition ™
Coopertition produces innovation. At
FIRST, Coopertition is displaying
unqualified kindness and respect in
the face of fierce competition.
Coopertition is founded on the
concept and a philosophy that teams
can and should help and cooperate
with each other even as they
compete.

Why
will require all youth team members of
FIRST programs to register.
Registration of youth team members is needed to:
The Lead Coach/Mentor will send the
parent/guardian an email invitation with
the registration link and team number.
Here parents/guardians will sign the
FIRST Consent and Release Form
(electronically)
And register their child/ren
•Establish a system of communication with parents
of team members
•Comply with Youth Protection policies by having a
way for FIRST to contact parents of participants in
case of emergency
•Provide Lead Coaches/Mentors with a Team Roster
that identifies their Team and makes management of
paperwork easier
•Provide FIRST with data on who is benefitting from
our programs, apply for funding and sponsorships
and help us grow our programs
•Reduce the cost and amount of paper that needs to
be processed at FIRST events, then shipped and
stored at Headquarters
