3 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.
4 Close Shave Rules and Procedure Load any programs you intend to use onto the NXT before requesting a check off on the challenge.Remember that you can load more than one onto the NXT at a time, and choose which one to run later.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: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!
5 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.
6 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.
7 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.
8 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!
9 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.
10 Zamboni Driver Rules and Procedure Use the rectangular ice arena board.The arena is empty (no nets or other obstructions).Position your robot any way you wish at the start.Run your program – you must use the same program regardless of the size of the arena.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!
11 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!
12 The Prairie Dog Burrow Rules and Procedure Start the robot in the Start area (marker #1)The robot must stop in the Goal area (marker #2).All walls are solid and elevated to a height of 8 inches.Reach the goal without making contact with any walls to complete the challenge!
13 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.
14 Driver Education - Intersections Rules and Procedure Use the City block rectangular area mat.All roads are clear of other vehicles and obstacles.You may position your robot in any way you wish at the start.Your robot must drive around the block, stopping at each stop line for at least one second.Your robot must NOT stop in other places.You may use only one program regardless of the rectangle’s size.Complete one full lap around the block to complete the challenge!
15 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.
16 The Clapper Mobile Rules and Procedure There is no board for this challengeWrite 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.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!
17 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.
18 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!
19 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.
20 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 10-second 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.
