The goal of this activity is to get students to move beyond the basics of understanding beams and connectors to taking learning further with movement. Students will be challenged to develop a LEGO EV3 2 motor car that moves accordingly to their code. This activity is building (no pun intended) upon the skills and ideas learned during the first challenge.

Additionally, the end result is to create the fastest moving robot. This classic challenge is one that never gets old and leads to some great engineering designs and gear comprehension. Students will be challenged to design and build a dragster than can measure and display its speed as it races down a 15 foot track.

1. To develop the skills to design and build a two motor car that is firm enough to allow movement.
2. To develop additional experience with beam and peg construction.
3. To develop knowledge to use coding skills to have a two motor car move through a course
   1. Program using the motor blocks
   2. Move the robot forward and straight
   3. Track the speed and time of the robot
   4. Utilize sensors to trigger a reaction

Bronze

A two motor car was designed and built that can complete the 15 foot track.

Silver

A two motor car was designed and built that can race when the that counts down 3-2-1 with voice commands and then declares "Start" to trigger the timer.

Gold

A two motor car was designed and built that can race when the that counts down 3-2-1 with voice commands and then declares "Start" to trigger the timer. The robot stops when it reaches the finish line using a color sensor to trigger the photoresistors on the ground.

Platinum

A two motor car was designed and built that can race when the that counts down 3-2-1 with voice commands and then declares "Start" to trigger the timer. The robot stops when it reaches the finish line using a color sensor to trigger the photoresistors on the ground. The robot displays it speed AND as well as the time.

If interested here is how I built and programmed the finish line setup.
