1. Sphero
Shaw STEM Lab

2. Objectives Create a scale representation of a geometric figure
Develop a strategy to accomplish a specific
Create a program for a robot to accomplish a goal
Complete an iterative testing process and document results accurately
Test and evaluate solutions to determine the most effective option

3. Welcome to the future of bowling with Sphero!
This bowling challenge is a little different than your standard 10-pin game.
Use the materials to create a bowling course with pins at three different locations.
Develop a strategy to knock them over and create a program that will help Sphero to autonomously make contact with as many pins as possible.

4. Vocabulary Autonomously Program Scale Drawing Pythagoras’ Theorem
Hypotenuse

5. Pythagoras Theorem C A B
This theorem states that the square of the hypotenuse (the side of the triangle opposite the right angle) is equal to the sum of the squares of the other two sides.
In the diagram to the right, which letter is the hypotenuse? C A B

6. Pythagoras Theorem C = ? 3 cm 4 cm
Example: Calculate the third side using Pythagoras Theorem
A2 + B2 = C2
= ?
= ?
= 25
C2 = 25
C = 5
C = ?
3 cm
4 cm

7. Tablet You must use the tablet to code Sphero, not your own device
Be responsible on how you use it
No inappropriate websites
Do not download anything

8. SPhero
The point of Sphero is to code Sphero to bowl, not to “free drive” it and not to move through your own obstacle course
Do not remove the cover

9. Materials you will need
Sphero
Tablet
Ruler
Meter tape
Protractor
Bowling Pins

10. Step 1: Create a course for your game
Calculate the third side using Pythagoras Theorem
A2 + B2 = C2
5.9 cm
5.6 cm

11. Step 1: Create a course for your game
Create a life size bowling course for Sphero
The course should be created as an exact 14:1 scale
For every centimeter in the example below, your course should be 14 cm.
5.9 cm
5.6 cm

12. Step 1: Create a course for your game
Find the precise middle of your triangle
This is where Sphero will start
5.9 cm
5.6 cm

13. Step 1: Create a course for your game
When the course is complete add the pins and mark the center of your triangle.
This is where Sphero will start

14. Step 2: Plan Your Strategy
You will need to determine how to program the Sphero so it makes contact with (or knocks over) as many pins as possible.
What will your strategy be?

15. The Rules Your course should be an exact 14:1 scale of the triangle
Sphero should be begin the game at the exact center of the course
You will have 1 minute for Sphero to make contact or knock down as many pins as possible
Your program must run autonomously. You cannot touch Sphero or control its movements manually with a smart device during the game.

16. Results ( Pins Knocked Over)
Step 3: Create & Test
Create your code
Test your code and document the results
Complete as many trials as necessary
Formulate a table similar to the one below

17. Questions/Research Did your program work as you expected?
Describe something that worked well and something that did not work well, or did not work as expected.
Describe any changes you made to your program to make it more effective.
