Title of Challenge: Point Turn A. Description (Short Paragraph): For the Point Turn Challenge, the team had to get the robot to do three different things. The first was to get your robot to go 25 cm forward. After that the robot had to do a point turn, which was 180 degrees. Next the robot had to back up 10 cm. The robot ends on backing up 10 centimeters.

B. Programming Code (Picture and Written Explanation): media type="custom" key="656559" Picture 1: This picture is what Mindstorms NXT looks like while programming something for your robot. All three of these blocks make it so the robot will move in a certain direction or to turn. You can choose what the distance or the degrees is for both of these.

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): During this challenge, the team encountered many difficulties. The most common difficulty was getting the robot to move in the right direction. It was also sometimes hard to actually get the robot to move. One of the hardest but least difficult challenge that was encountered was putting the right dimensions in the NXT software. These problems were resolved by estimating, guessing, and most definitely doing it over and over again until it was right. These problems were hard to fix, but when the team got the hang of it, we could fix the problem quickly.

Title of Challenge: Square A. Description (Short Paragraph): The square challenge is when the robot has to take multiple turns and go on multiple straights. The robot has to take the different turns and go on straights to form a square formation. The turns and straights are the same dimensions for each and every one since it is a square. B. Programming Code (Picture and Written Explanation):

media type="custom" key="679709" Picture 2: Programming Code for Square This is what the programming code for the square challenge looks like. In each of these blocks, the robot is being told to either move for a certain amount of dimensions or turn a certain amount of degrees. The degrees and dimensions are similar for each block, but they are not always exactly the same. Since our team is trying to make the robot move in a square, the first, third, fifth and the seventh block are similar dimensions and the second, fourth, and sixth blocks are also similar.

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): While our group was programming the robot to complete the square obstacle course, we encountered only a few difficulties. One difficulty was getting the robot do go the correct distances. It was also hard to have the robot stay on the lines while completing the obstacle course. It was easier than other challenges because the distances were the same for each, since it was a square. This made it easier for the robot to complete the course. The only problem with this is that the course had some different dimensions because of the robot. Getting the PERFECT dimensions was probably the hardest aspect of this obstacle course. _

Title of Challenge: Backing Up A. Description (Short Paragraph): In the backing up challenge you had to go straight then make a gradual turn then come to a stop. After you come to a stop the robot backs up while making a sound to complete the course. B. Programming Code (Picture and Written Explanation): Picture 3: Programming code for the backing up challenge. C. Multimedia: media type="custom" key="685515" Video 4: Challenge 3 of robot D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): The difficulties that our group encountered in this challenger were making it back up and doing the gradual turn. When we try'ed to make it back up it would not go the right amount. To fix this problem we would just try different amounts and see how much further it needed to go or if it was not going far enough. The gradual turn was hard because the robot did not turn turn enough or turned way to far. We solved this by reducing the amount of degrees it turned or increasing the amount of degrees it turned.

Title of Challenge: Make Your Own Obstacle Course A. Description (Short Paragraph): This challenge is very difficult. The teams have to make our own obstacle course and program the robot to go through it. While programming the robot there is measurements to be taken, the distance and turns. There is a limited amount of time to program and make the obstacle course. At first, the robot has to go straight for 38 1/2 centimeters, then makes a 90 degree turn. The robot, then goes straight for another 22 centimeters. There is another turn for the robot at 130 degrees. The robot goes straight for 29 centimeters. Once again, the robot makes a 60 degree turn. The robot then has to go straight for 26 centimeters and a 90 degree turn. You go straight for 19 centimeters and a 63 degree turn. B. Programming Code (Picture and Written Explanation): Picture 4: Programming code for Make Your Own Obstacle Course

This is a picture of how our group made the robot complete the obstacle course. The first block makes it so when the robot hears a noise, it will start. The next 9 blocks are what makes the robot turn for certain degrees and move for certain distances. The last block in the programming code makes it so when the robot sees a color light or dark, it will halt. The programming code is hard to do but it is very fun to figure out.

C. Multimedia: media type="custom" key="661801" Video 5: Interview of Sydney and Brittany about Obstacle Course D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): The group encountered a few problems during the challenge. The first problem was to make the robot do exactly what you need it to do. Also, a problem that was encountered was getting the measurements right. The group solved the problem by repetitively changing the measurements on the Lego program until it was done to perfection.

_________________________________________ 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.

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. 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.

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!)

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.
