TODAYS CHALLNGE Controller operation Autonomous OR Maze Navigation Today’s challenge is to navigate a maze set out in front of you. The brief sets out the following task: “Design and programme your robot to navigate a maze where there is a need for a zero degree rotation at a single point. The robot must navigate the maze either controlled or autonomous, but is not allowed to touch the sides of the maze at any time. The robot must only touch the target pad at the end of the maze.” In your teams, discuss the challenge and decide if you want to create an autonomous or controller operated robot solution.

LESSON 08

LESSON 08 STARTER Learning objective: Analyse the design brief. Establish a range of solutions for a robot that consider autonomous and controller type robots. Propose, build, test and present a working solution as a team. In your Notebook… Task 1: Note down all the elements of the challenge and draw a detailed drawing of the arena you are going to compete over set down by your teacher. Things to note: - dimensions of any items you need to interact with (objects and parts of the arena) - number of objects in the arena you need to interact with - the time limit you have to complete the challenge - any initial issues you have identified based on your existing robot build Key words: Programmable, environment, design, manufacturing and application

MAZE CHALLENGE The maze Your task is to navigate the maze set out by your teacher (see right for an example). You will need to work out your route, measure the distances (for autonomous) and make sure your robot will be able to make the required turns in the maze. This might need you to programme your robot controller to allow for zero degree turns, or simple turn sharper through practice and skill.

LESSON 08

LESSON 08 Challenge Time “Design and programme your robot to navigate a maze where there is a need for a zero degree rotation at a single point. The robot must navigate the maze either controlled or autonomous, but is not allowed to touch the sides of the maze at any time. The robot must only touch the target pad at the end of the maze.”

LESSON 08 PLENARY As a class, let us consider the following questions? A. Why did you choose autonomous/controller? B. What was the benefit of choosing the other in hindsight? C. What aspects of controller and autonomous could you combine for a better solution? D. What made autonomous/controller hard to achieve the perfect solution?

SUMMARY Today you have: Learning objective: Analyse the design brief. Establish a range of solutions for a robot that consider autonomous and controller type robots. Propose, build, test and present a working solution as a team. Today you have: Learnt to discuss in teams the analysis of a design brief Developed solutions for a robot challenge using autonomous and controller solutions Developed a robot solution which can be tested and evaluated
