AR Day 18-22

· Students will build a drag race car and program it to go 20 feet in the least amount of time. Each group will only get two (2) motors.

Mission: Your team’s challenge is to create a robot which can cross a 20 ft distance in the least amount of time possible. Your car must stay within the track (8' wide). You will have 2 opportunities to race your car against the clock. You are trying to get the lowest time possible. Program your robot dragster to stop as soon as it crosses the line at 20 ft. Students will need to add a bumpSwitch to start the robot.

· Students will time their drag car on AR Day 21 and 22.

· Students are graded on times:

Steps for building:

1. Find the location for your axles. Attach the 3 hole black parts to your short rails.

2. Select your gear sizes.

3. Attach your motors to your short rails. Also attach your gear to your motor with a 2" axle (The shortest axle in your kit).

4. Attach your short rails to your L-brackets.

5. Attach your long axle (Labeled Long Square Shaft located in the wooden cabinet) with the gears attached to at least one of the long axles.

6. Attach your wheels.

7. Attach your medium plate, coretex, and bumpSwitch.

8. Write your program. Save it as: Last name Drag Car Task 1.
