We will be engineering our own Sphero chariot that will be able to race competitors, while navigating a maze, while holding a real chicken egg intact.
In ancient times, people used something called a “chariot” (a cart, usually pulled by horses) to haul materials, build things or even race against each other.
First - Draw a sketch of what you already know about what a horse-drawn chariot looks like. Be as detailed as possible, but draw based on what you already know. Don’t look online (yet!) Document your drawing on your website.
Second - Create a new Google Slide that includes the Chariot Engineering Design steps
Slide 1: Title
Slide 2: Define
Slide 3: Research
Slide 4: Prototype
Slide 5: Sensitivity Analysis
Slide 6: Final Build
Challenge Information -
Your group challenge is to design and build a Sphero chariot that is capable of holding 1 regular sized raw chicken egg as your chariot "Driver". The goal is to race the chariot as fast as possible without breaking the egg.
Prototype Supplies -
The equipment you have access to is a computer, 3D printer, hot glue gun. The materials you may use are 3D printer filament (Only for 3D printer use), scissors, hot glue gun sticks (only for hot glue gun), plastic straws, wooden skewers, recycled cardboard, paper clips, and popsicle sticks. Your group must create at least 1 chariot part using a 3D printer.
Final build supply Information -
Use your prototype as a guide to create a final chariot build. The final build is created only using prototype supplies.

Rule 1: You will only receive 2 raw chicken eggs
Rule 2: Startline begins on the bottom left, the line finish is on the bottom right
Rule 3: Chariots must circle all colored blocks
Rule 4: Must race the entire race with a raw chicken egg for the entire race. If the egg falls out during the race, you may restart the race, but your time will not restart.
Rule 5: All races must be recorded for personal website documentation and slow-motion point justifications.
Rule 6: Sphero must pull the chariot through the course. If the chariot disconnects from Sphero, you may restart the race, but your time will not restart.
Rule 7: Only ONE driver for the entire race.
Disqualification 1: bumping into blocks while in drive mode +4 seconds onto final time. Bumping into blue blocks while coding +2 seconds onto final time
Disqualification 2: bumping into yellow/red blocks while in drive mode +4 seconds onto final time. Bumping into yellow/red blocks while coding +2 seconds onto final time
Disqualification 3: bumping into pool noodle while in drive mode +4 seconds onto final time. Bumping into pool noodle while coding +2 seconds onto final time
Disqualification 4: Chariot not having 3D print part +8 seconds to the final time
Disqualification 5: Time in race course of more than 2 minutes is an automatic disqualification.
