=II. Instructions for Challenges=

A. For each challenge you must write a short description of the challenge using complete sentences. Please write in 3rd person, scientific writing. B. This is where you should include your programming code by including screen screen shots. You should place all multimedia on [|photobucket.com] and then incorporate it into the site using the embed code. C. For each challenge you must provide some form of multimedia exhibit. This would be images, a short video, an interview, etc. You should place all multimedia on [|photobucket.com] and then incorporate it into the site using the embed code. D. For each challenge you should provide a written explanation of the difficulties encountered with the challenge. = = = = =III. Challenges (Template)=

DATE: 4/8/2008 Title of Challenge: A. Description (Short Paragraph): The point of this challenge is to make your robot move around a square. You have to master the point turn and making your robot go in a straight line. First, the robot would go forward 61 cm. Second, the robot turns 90 degrees to the right. Thirdly, the robot must repeat this three more times. B. Programming Code (Picture and Written Explanation): The first brick makes the robot move forward 61 cm. The second brick makes the robot turn 90 degrees to the right. C. Multimedia:

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): We had many problems. Our first problem was that the robot was overturning. We had to play around with the rotation of the wheels. Our next problem, was that the robot wouldn’t go far enough. We had to play around with the rotations on the second brick.

DATE: 4/10/2008 Title of Challenge: A. Description (Short Paragraph): Our first project was the point turn project. In this project you have to first make the robot go forward in a striate line. Next we have to make the robot turn one-hundred degrees. Then finally the robot must back up and come to a stop.

B. Programming Code (Picture and Written Explanation):

This means that the robot will go forward then turn then back up. C. Multimedia:

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph):

During the programming we had some difficulties. One of the difficulties we had was we had to figure out how many cm equal one rotations. Another similar problem was that we have to figure out how many degrees equal one rotation. The way we solved the first problem was we found the circumference of the wheels. As for the second problem we had a more difficult time we just did the guess and check method. Once we solved these problems the information helped us in all of the challenges.

DATE: 4/11/2008 Title of Challenge: A. Description (Short Paragraph): This was one of the hardest challenges. It earns this title from the gradual turn that is very hard to figure out how to work. You have to program the robot to execute a gradual turn, stop, backup, and make a sound while it’s backing up. This is very hard to do. B. Programming Code (Picture and Written Explanation): The first brick makes the robot move forward to the point turn. The second brick executes the point turn. The third brick makes the robot turn slightly to align itself with the backup line. The fourth brick plays a noise. The last brick backs the robot up.



C. Multimedia: D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): Our first problem was that the robot was turning to far. We had to play around with the degrees a bit. Our next problem was that the robot was backing up to far. We had to play around with the last brick a bit. Those were our problems.

Task 1 (10 points): At your work area on the table come up with a strategy to calculate the velocity of your robot at 30% power over 70 cm. Repeat the measurement 3 times and get an average. Think about the equation for velocity. Carry out your plan and determine the velocity.

our strategy was to lay out a tape measher out one the table then time how long it would take for the robot to gt to the 70 cm mark. our answer was 70/8 or 8.75cm/s

a. Brief description and image (snip and you can upload to the wiki- give your image an uncommon file name) of the programming you used to solve this challenge. In this challenge we measured how far the robot went and devided that by how long it took the robot to go that far.



b. Description of what made this task difficult for your group.

Task 2 (20 points):: At your work area, come up with a strategy to get your robot to accelerate over a 1 meter distance. Have it come to a stop at 1 meter.

a. Brief description and image (snip and you can upload to the wiki- give your image an uncommon file name) of the programming you used to solve this challenge. we made a progam that periodecly increased the speed of the robot and costed inbtween rather than stoping.



b. Description of what made this task difficult for your group.

Task 3 (30 points):: Determine the velocity of the rotation of the wheels on your robot. Program your robot at 45% power to rotate 10 times. Calculate the velocity of the rotation of the wheels at this power in cm/sec. (Hint: You need to know the circumference of a wheel and remember it goes around ten times!)

a. Brief description and image (snip and you can upload to the wiki- give your image an uncommon file name) of the programming you used to solve this challenge. In this challenge we measured how far the robot went and how long it took to go that far. We then devided the distance by how far it went. b. Description of what made this task difficult for your group.

Task 4 (40 points):: On a graph, plot the velocity that your robot travels 1 meter at 20% power, 40% power, and 70% power. Include an image of your plot in your documentation by snipping it. Make sure it has units and axis labels. Using your graph, determine how fast you think your robot wold be traveling if you programmed it to go at 60% power. Calculate velocity in cm/sec. a. Brief description and image (snip and you can upload to the wiki- give your image an uncommon file name) of the graph. b. Description of what made this task difficult for your group.

Task 5 (50 points):: Create an obstacle course on your lab table with building bocks. It should contain one right point turn and 1 left point turn. The robot should stop at the end where you have built a small tower of blocks. Your robot should not knock the blocks over.
