Challenge Outcomes:
ALL students will: Successfully design and build a device which is geared up
MOST students will: Successfully design and build a device which travels faster than a standard Lego Mindstorm motor
SOME students may: Successfully design and build a device which travels faster than a standard Lego Mindstorm motor and in straight line.

Project Overview:
A standard Lego Mindstorm device with no gears can travel 10 meters in approximately 20 seconds.
Your task is to create a device that can travel 5 meters in 5 seconds. Welcome to gears!
You may use maximum 2 large motors and 1 medium motor.
The device must be activated by a touch sensor.
Your code must run for 5 seconds, maximum.
Main Activities:
Main Activities:
Part 1: Design
Part 1: Design
a) In your robotics planning pad, create two annotated sketches of the device you wish to build
b) Create a flowchart displaying your devices functionality - remember to include decisions if your device has sensors
c) Explain your idea to your partner. You are now to choose between both ideas to build.
Part 2: Build
Part 2: Build
a) Build your device - the device must be similar to the plan (small changes are allowed)
Things to note:
The lighter the device, the quicker it will go
The thinner the wheels, the less friction there is on the surface
Part 3: Program
Part 3: Program
a) Program the device.
You must ensure the devices functionality is similar to what was planned in Part 1.
Part 4: Test
Part 4: Test
a) Now is the time to test that your device works!
