Move Straight Ahead Challenge
Close Shave
• In this challenge, you
must drive your robot as
close as possible to a
LEGO minifig without
knocking the minifig over.
The minifig will be placed
at one of three locations,
with the specific spot
determined by a coin
toss.
Close Shave Rules and Procedure
1.
Load any programs you intend to use onto the NXT
before requesting a check off on the challenge.
2.
Remember that you can load more than one onto the NXT at a time, and
choose which one to run later.
3.
Start the robot behind the black line (no parts
overhanging)
Place the minifig 1 floor tile away from the line, or 30 cm.
Flip two coins.
For each “heads” result, move the minifig back one tile
(or additional 30 cm increment).
Choose a program from the ones you have prepared,
and run it.
Calculate your score:

9.
Start with 100 points.
Measure the distance from the closest piece on the FRONT of your robot to
the FRONT of the minifig’s chest.
Subtract 5 points for every 0.1 cm of distance between the minifig and the
robot.
Earn a score over 80 points to complete the challenge!
Moving and Turning using
Rotations and Degrees Challenge
Sprint, Spin, Sprint
• Your robot must run
out to the circle, spin
three full circles and
return to the starting
point as quickly as
possible.
Sprint, Spin, Sprint
Rules and Procedure
•
•
•
•
•
Begin behind the black starting line.
The robot must move to the inside of the
circle, and turn at least three full times
around.
The robot cannot leave the circle while
spinning, or it will be disqualified.
The robot must return to its starting
location when it is done.
Beat the challenge by competing the drill
in under 15 seconds.
Making Accurate Turns Challenge
The Labyrinth
•
This challenge features
a sequence of turns that
the robot must perform
in order to get to the end
of the maze. The robot
must begin at the
starting point (#1 below),
and get to the goal area
(#2) using moving and
turning behaviors.
The Labyrinth Rules and Procedure
• Start the robot in the Start area
(marker #1)
• The robot must stop in the Goal area
(marker #2).
• The robot must not cross any lines
while traveling (except the “stripes” in
the Goal area).
• Reach the goal area to complete the
challenge!
Touch Sensor Challenge
Zamboni Driver
• In this challenge, you
must program your
zamboni-equipped
robot to sweep the ice
by touch all four walls
of a rectangular
arena.
Zamboni Driver Rules and Procedure
1. Use the rectangular ice arena board.
2. The arena is empty (no nets or other
obstructions).
3. Position your robot any way you wish at the
start.
4. Run your program – you must use the same
program regardless of the size of the arena.
5. Your robot must sweep around the arena as
quickly as possible making physical contact
with all four walls of the arena during a single
run (without getting stuck) to complete the
challenge!
Ultrasonic Sensor Challenge
The Prairie Dog Burrow
This challenge features a
layout using electrified
walls. The robot must begin
at the starting point (#1
below), and get to the goal
area (#2) using moving,
turning and senor
behaviors. Your robot must
use its sensors to help
navigate the maze without
touching any walls!
The Prairie Dog Burrow
Rules and Procedure
1. Start the robot in the Start area (marker
#1)
2. The robot must stop in the Goal area
(marker #2).
3. All walls are solid and elevated to a
height of 8 inches.
4. Reach the goal without making contact
with any walls to complete the challenge!
Light Sensor Challenge
Driver Education - Intersections
In this challenge, you
must program your
robotic vehicle to drive
around a model city
block, stopping
appropriately at each
intersection according
to the stop lines, then
proceeding.
Driver Education - Intersections
Rules and Procedure
1. Use the City block rectangular area mat.
2. All roads are clear of other vehicles and obstacles.
3. You may position your robot in any way you wish at the
start.
4. Your robot must drive around the block, stopping at
each stop line for at least one second.
5. Your robot must NOT stop in other places.
6. You may use only one program regardless of the
rectangle’s size.
7. Complete one full lap around the block to complete the
challenge!
Sound Sensor Challenge
The Clapper Mobile
In this challenge, you
must program your
robotic vehicle to start
driving when someone
claps, then stop with a
second clap.
The Clapper Mobile Rules and Procedure
1. There is no board for this challenge
2. Write a program that creates the following
behavior:
•
•
•
•
•
The robot remains stationary, and stays that way until...
You clap.
The robot starts moving, and doesn’t stop until...
You clap again.
The robot stops after the second clap.
3. Complete the challenge by demonstrating this
behavior!
Hint: A clap looks like a large spike in sound volume. A spike is
composed of two parts: a sharp rise, and a sharp drop in
volume. Make sure the first clap is done before you start
listening for the second one!
Repeating Behaviors
Lego Sentry Service
• Your company has been commissioned to design a robot
to patrol the perimeter of a building. You are tasked to
develop a “proof of concept” prototype that can travel the
designated “loop” route around the building.
Lego Sentry Service
Rules and Procedure
•
•
•
•
•
•
Use the Sentry setup which includes the
central building and surrounding fence.
The building is rectangular in shape. The fence
Posts are 1” diameter PVC tubing with string to
represent the fence.
Your robot must complete two full laps around
the building.
Your robot must not come into contact with the
building, fence or the posts marking the fence.
Your program must incorporate at least one
Loop Block.
Make two complete laps using a loop to
complete the challenge!
Line Following Behaviors
X Games Slalom Course
• In this challenge, your robot must reach the end
of the slalom course as quickly as possible,
without knocking over any of the posts along the
route.
Lego Slalom Course
Rules and Procedure
•
The line marking the course are dark on a light-colored
surface, Posts are made of 1” PVC tubes.
A stopwatch will be used to time your robot’s run from
the time the Run button is pressed, to the time any part
of the robot crosses the finish line.
•
–
–
Knocking over any gatepost incurs a 3-second penalty per
post.
Missing a gate (not going between the posts) incurs a 10second penalty per gate.
•
Complete the course in under 15 seconds (including
penalties) to complete the challenge! Fastest time
wins.
Hints:
–
You can run different optimized line tracking behaviors
one after another to go fast or turn sharply when needed.
