1. Navigate a maze you build using a robot you program!
Sphero Maze Madness!
Navigate a maze you build using a robot you program!

2. What is Sphero?
Sphero is a robot you can control via Bluetooth connection on your iPad or Android device
You can use it like a remote controlled robot, or program it to do certain actions at certain times.

3. Roles within your Group
Measurer – measure distances and angles
Recorder – record rate, distance, time
Drafter/Drawer – draw the maze on paper
Calculator – calculate the rate Sphero travels, how far and fast it needs to go
Instruction Writer/Reader – write, read and help interpret written language instructions
Programmer – enters the code into Macro Lab
Tester – tests the program to make sure your group is on the right track

4. Building the Maze (15 minutes)
You can create different pathways through the maze with books, boxes, ramps and tubes
Make it challenging, but not too challenging! Other teams have to go through the maze, but so do you!

5. Data Gathering (30 minutes) Find the rate of speed the Sphero travels
Draw the maze and choose your path
Take measurements of distances and angles to follow the path you have drawn

6. Planning
(30 minutes)
Convert your data into written instructions, using plain language
Don’t skip any steps!
At the end, you should have a list of instructions in your own words of how to make the Sphero navigate the maze

7. Programming (90 minutes)
Convert your written instructions into commands in Macro Lab
Don’t skip any steps!
Remember, good coders test as they go!

8. RACE!! (45 minutes) Race against each other
Winners will be determined by the following:
Staying within the maze
Completion of maze
Anything else?
HAVE FUN!

9. Build the Maze – you have 15 minutes!
Let’s get started
Build the Maze – you have 15 minutes!

10. Gather Data (30 min) Find the Rate of Speed (Calculator)
(Rate = Distance/Time)
Create a Macro where the Sphero moves straight forward for 1 second at 100% speed
1000ms = 1 second
Measure how far it traveled in 1 second
Draw the Maze on Paper (Drafter)
Determine the Path your Sphero will take (Entire Team)
Take measurements of distances and angles (Measurer)

11. Planning (30 min) Convert your data into specific instructions
Write down those instructions in plain language (Instruction Reader/Writer)
Don’t skip any steps!
Remember, you have to tell the Sphero to do EVERYTHING you want it to.
At the end, you should have a list of written instructions in your own words of how to get through the maze.

12. Programming (90 min)
Convert your specific instructions into code on the iPad in Mac Lab (Programmer)
Remember to test as you go!

13. RACE!!
(45 minutes)
