Printer-friendly version
Participants: Team
Objective: To draw 3 squares on top of each other.
Points Possible: 100
Rules and Procedures:
You will need about a four foot by four foot white board that can be laid on the floor. You should use a dry erase marker with a rubber band to hold it to your assembly.
- The robot can start anyplace on the white board.
- You need to make an approximately 90 degree turn.
- Each straight line of the square should be at least 1 foot long.
- You have unlimited time.
- The 3 squares need to be consecutive.
- Minor pen skips are ok if it is easy to see where the line is.
Grading Guide:
We grade the parallel lines (corners can be rounded or any shape).
- You get unlimited attempts to do the challenge correctly for full points
- If the lines on the sides of the squares are within 1-inch of each other you can get 100 points.
- If the lines on the sides of the squares are within 1 1/2-inchs of each other you can get 90 points.
- If the lines on the sides of the squares are within 2-inchs of each other you can get 80 points.
- If the lines on the sides of the squares are within 3-inchs of each other you can get 70 points.
- If the lines on the sides of the squares are within 4-inchs of each other you can get 60 points.
- Scores under 60% are not acceptable and you must keep trying.
Notes:
- You can practice as much as you want.
- Tell your instructor when you have an official attempt. Your instructor should be able to clearly see your lines.
- You can slow your robot down using gears.
- If your wheels are slipping you may want to clean your wheels or the surface of the white board.
- Friction can make a big difference on this challenge. There are a lot of places that friction can affect your robot performance. The friction of the pen on the white board can also be a factor.
