Algebraic Equations:
• A machine capable of carrying out a complex series of actions automatically.
• A machine that senses the world, processes sensor information with a computer, and then does something in response to the information.
• Roomba – small round vacuum sweeper.
• Litter Robot – self cleaning litter box for cats.
• Aibo – robotic pet.
• Lawnbot – robotic lawn mower.
• Hexbug – robotic toys.
IntroductionIntroduction• Hands‐on, inquiry‐based missions.• Ten missions and three exploratory extensions.
• Missions are built sequentially upon knowledge from prior activities.
• Students discover math concepts by programming robots to complete challenges.
• Math and technology• Grade Levels: 6th – 8th
Subject AreasSubject Areas
• Basic operations and concepts• Technology productivity tools• Technology research tools• Technology problem solving and decision making

• Numbers and operations• Algebra• Geometry• Measurement• Data analysis and probability• Problem solving
Mathematics
• Use the calculator to program your robot to perform various tasks.
• Step‐by‐step programming instructions are provided in the first missions, gradually leading you to create your own program in later missions.
• There are 10 different mission challenges.
• Each challenge is built upon the knowledge of the previous one.
• As you program your robot think about the math and science concepts you are using.

• Cameras find objects, people, or other robots.• Global Positioning Systems receivers determine the location.
• Laser rangefinders determine distances between objects.
• Light sensors detect the brightness of the environment
• Temperature sensors detect how hot or cold the environment is.
• Touch sensors detect hard surfaces.

Command = 123
First number is the type of command• 1 = Move for a certain amount of time• 2 = Move until the front bumper hits something• 3 = Move for a certain time unless the front bumper hits something first
Command = 123
Second number tells the left wheel what to do• 0 = Rotate backward• 1 = No motion• 2 = Rotate forward
Command = 123
Third number tells the right wheel what to do• 0 = Rotate backward• 1 = No motion• 2 = Rotate forward
For each command below, what do you think the robot will do?
