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.

Title of Challenge: Challenge 1 A. Description (Short Paragraph): In this challenge, the robot moved forward 25 cm. Then, it turned 180 degrees and moved backward 10 cm. The 180 degree turn was a point turn in which it completley stopped and turned 180 degrees. B. Programming Code (Picture and Written Explanation): Image 1: Challenge 1 programming code. The first block of the programming code made the robot go forward 25cm. The duration was 1.5 rotations. The second block made the robot do a 180 degree turn. The last block made it go backwards for 10 cm and come to a stop. The robot basically went in a straight line with a turn in the middle. C. Multimedia: media type="custom" key="3716511"

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): Some difficulties were to make the robot turn a complete and full 180 degrees because it always either turned over 180 or below 180 the rest was not as challenging.

Title of Challenge: Challenge 2

A. Description (Short Paragraph) The goal of the experiment was to make the robot move across a square with 63 cm length of each side. It was supposed to stay on the tape throughout the run through. If the robot went of the tape the challenge was counted off. B. Programming Code (Picture and Written Explanation): Image 2: Challenge 2 programming code. The first block was to move forward 63 cm, the second block made the robot turn 90 degrees, the third block made the robot move 63 cm, the forth block made the robot turn 90 degrees, the fifth block made the robot move 63 cm, and the sixth block made the robot turn 90 degrees and the finale block made the robot go move 63 degrees.

C. Multimedia: media type="custom" key="3716417" D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): A difficulty which was encountered was to make the robot turn only 90 degrees and not anything over that. In the procedure that we did it only moved a couple centimeters to the left. This didn't make the robot go a full 90 degrees. Another difficulty encountered was we copied the same procedure for each straight turn. This made the procedure inadequate.

Title of Challenge: Challenge 3

A. Description (Short Paragraph): This challenge was to go straight 68 cm and the turn right about 90 degrees. It was then supposed to back up 53 cm while making a sound of some sort. B. Programming Code (Picture and Written Explanation): Image 3: Challenge 3 programming code. The first block of the code made the robot go forward for 68 cm. It had 3.2 rotations. The next block made the robot do about a 90 degree turn. It had 2.5 rotations. The next block made the robot make a sound while it moved back 53 cm. The last block made it move back 53 cm and come to a stop. C. Multimedia: D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): Some difficulties encountered were that when it was supposed to go forward 68 cm it went to far. This made the challenge difficult when we went lower or higher. Another difficulty that we encountered was that when the robot turned it sometimes when to far and did a full 180 degree turn!

Challenge 4 A. Description (Short Paragraph): In this challenge we had to create our own track using tape, there is a picture under multimedia of this track. There were some expectations which had to be met they had to have a sound and sight sensor. The sound sensor was to start the course and the sight sensor was to end it. Also there had to be three turns, one point turn and another gradual turn and a normal turn. This challenge was different from the others

Why challenge 4 was not completed:
Challenge 4 was not completed because the robot would not calculate the coordinates correctly. The first day that the challenge was started, the robot worked perfectly and almost completed the challenge. However, the next day the robot did the complete opposite of the course. The robot coordinates were redone so it worked at the end of the day, but the next day the robot did the opposite again. The course could have been completed in a day, but the rebooting of the robot and the restarting of the coordinates took away precious time. That is why challenge 4 was not completed.
