FIRST® at Home Programming with Romi Robot Project Essentials SUMMARY Students will explore declarative programing using the WPI Library software. They will build a mobile robot chassis using the Romi Robot and make their machines interact with its environment and perform tasks autonomously. This activity series builds programming skills and knowledge related to performing in a role as a programmer role on a FIRST® Robotics Competition team. Students completing these activities should have some knowledge and experience with programming or coding. If you are just starting out programming look at the other coding and programming skill building activities on FIRST at Home. Age Range & Grade Level: Ages 13 +, Grade 8+ Program Connection: FIRST Robotics Competition ® Authored By: Lori Birch, Curriculum Developer, FIRST Education OUTCOMES 1. Identify the problem and brainstorm solutions using a mobile robot and programming. 2. Decompose the technical documents of the Romi robot system. 3. Create a simple program using the WPILibrary and command-based programming design. 4. Using data from your robot, create a subsystem that improves the functionality of the machine. 5. Iterate your code to create the optimal solution for your robot game, finalize game criteria and present your game.

This is a portion of the robot control system and includes a variety of libraries and tools. This programming library can support a variety of programming languages: Java, C++ and LabVIEW. In this activity you will begin to use basic algorithms and robot logic. In this scenario, as future innovators and problem solvers, that want to make an impact in the community, you are tasked designing a robot game that can be played using the Romi robot and WPILib contraints. CRITERIA & CONSTRAINTS • The game can be played with a single player or two players. • Your plan should include how to demonstrate FIRST® Core Values. • The robot used will be the Romi robot. • There should be an autonomous and/or teleoperated driver-controlled period. • Develop a decision matrix that will determine the tradeoffs you will need to make in determining the robot design based on the Romi robot. • Make a plan using pseudo code that uses a command based format. ENGINEERING DESIGN PROCESS & FIRST CORE VALUES FIRST Engineering Design Process | Explore FIRST Core Values INTRODUCING ROMI ROBOT Watch the FIRST Hour of Code episode clip & explore the documentation for the Romi robot. Command-based programming is method to organize a robot code or algorithm. This is known as declarative programming and the algorithm is made up of commands for the robot to execute. To execute a command you must first define the desired robot behavior. Now that you have reviewed the Romi documentation think about your game design create some basic commands using pseudo code to define basic robot behaviors. Determine tradeoffs of your robot design to meet the game design. GAME DESIGN • What makes a good game? • What materials do you have available to create a game? • Will you be creating the game as an individual or can multiple people participate in your game? • How will the game tasks take into account the restrictions of the Romi robot? GAME FIELD EXAMPLE Below is an example diagram of basic layout of a game field. Use the space below to design your own field set up. Determine what materials you need for the field and what is avalible for you to use. BRAINSTORM IDEAS FOR YOUR GAME DESIGN AND PROTOTYPE Brainstorm 2 or 3 examples of optimal robot play in the space below. Use a sketch or diagram as needed. REFLECTION QUESTIONS 1. How can data gathered by sensors lead to algorithms for robots to make decisions? 2. How does the design of a game affect the design of a robot? 3. What specific features of command-based program make it useful for programming robots? 4. What programming language will you use to program your Romi robot? GOING FURTHER (OPTIONAL- SEE MATERIALS NEEDED) Incorporate sensors on to your robot. Explore the sensors in the optional accessories for the Romi to see the options that are integrated into the WPIlib. • How is data gathered in an environment with sensors? • What sensors are available? • What data does the sensors measure to be used to make decisions?
