3. TODAYS CHALLENGE Controller operation Autonomous OR
Building Blocks Today’s challenge is to build up a series of child’s play blocks as high as possible. You are competing against the other teams in your class. The brief sets out the following task: “Design and programme your robot to pick up and stack blocks one on top of the other. The robot must stack the blocks either controlled or autonomous, but teams are allowed to place the blocks into a “zone” from where the blocks are grabbed if desired. Students could alternatively use sensors to programme the robot to find and pick up blocks.” In your teams, discuss the challenge and decide if you want to create an autonomous or controller operated robot solution.

5. LESSON 10 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

6. BLOCK STACKING CHALLENGE
The Blocks
You are challenged with picking up and stacking the wooden blocks provided by your teacher. You will be allowed to set them down in a scoring tile for the robot to pick up, then operate the robot to stack them in a scoring square. The taller the tower the higher the score.

7. BLOCK STACKING CHALLENGE
The Scoring Arena
The scoring arena will be set out like you see here. Your task is simply to ensure your robot can operate in this space and build the blocks up. Blue square – the place where you will pick up the blocks as they are set down by one of your team. Red square – the area where you can stack your blocks. The highest stack anywhere in this square will be measured as your challenge outcome.

Challenge Time “Design and programme your robot to pick up and stack blocks one on top of the other. The robot must stack the blocks either controlled or autonomous, but teams are allowed to place the blocks into a “zone” from where the blocks are grabbed if desired. Students could alternatively use sensors to programme the robot to find and pick up blocks.”

10. LESSON 10 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?

11. SUMMARY Today you have:
