<span style="FONT-FAMILY: 'Trebuchet MS',Helvetica,sans-serif">Title of Challenge: The Point Turn

A. Description (Short Paragraph): This challenge consists of making a robot do three steps. First, the robot has to move 25 cm forwards. Then, the robot does a 180 degree point turn to the left. Finally, the robot has to travel 10 cm backwards. This is all programmed on the NXT software.

B. Programming Code (Picture and Written Explanation): First, the NXT software has to be accessed. The "moving" icons are pulled into the programming area where they can then be adjusted. Image 1: Programming the Robot Personalizing the first action is done by scrolling to the bottom of the screen and adjusting the settings. Through this the changing of the units of measure, which way it goes, how fast it goes, the duration of the reaction& the actual procedure itself, can be adjusted. Image 2: Adjusting the Settings The last step is compiling the information and putting it on the robot to be tested. Image 3: Compiling the Information

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): There were many difficulties encountered when programing the robot. The 180 degree turn was the most difficult one, though. First, the group attempted a turn and the robot turned too little. Then, once the turn was adjusted, the robot turned too far. After many adjustments to the turn, the robot finally turned the correct amount. <span style="COLOR: rgb(255,0,183); FONT-FAMILY: 'Trebuchet MS',Helvetica,sans-serif"> <span style="COLOR: rgb(251,112,242)"> =<span style="COLOR: rgb(251,112,242)">DATE: 4/18/2008 = Title of Challenge: The Square

Square:
Instructions: Your robot must follow the square drawn on the floor at the front of the room. A: description (short paragraph): For this challenge the robot was given a path on the floor to follow. It was in the shape of a square and each side was the length of 2 floor tiles. The robot had to be programmed to follow the square around all 4 sides, and then break at the end. To do this the NXT software was used.

B. Programming Code (Picture and Written Explanation): For programming the robot on the square challenge the robot had to move in a square. Then it had to turn at an 360 degree angle and go straight for 2.7 seconds. Then the robot repeated that movement until it got fully around the course. In the picture above there are 7 blocks. block 1,3,5, and 7 are all straights, and blocks 2,4, and 6 are turns. Image 4: Programming for the square

C. Multimedia: media type="custom" key="686835"

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): There weren't very many difficulties that were encountered during the square challenge. The only problem that was found was determining how far the robot had to travel on each straight. After many trials and errors the team finally pulled through and completed the task. The course was one of the simpler ones assigned so far in robotics though. It consisted of three turns and four straights. Overall the challenge was fairly easy and not as complex as many of the others have been.

=<span style="COLOR: rgb(243,68,201)">DATE: 4/18/2008 = Title of Challenge: Backing Up A. Description (Short Paragraph): In this challenge the robot must follow a path drawn on the floor. The path goes forward adn then makes a right hand wide turn, and then backs up while making noise. To do this the NXT software was used, and it took around 15 minutes for the group to complete. It was a difficult challenge in which the programming was hard to do.

B. Programming Code (Picture and Written Explanation): Programming the robot to follow the drawn out path was difficult. It started out going straight for around .3 seconds. Then it made a long and wide 90 degree turn to end up at the second point. Next the software was used to send the robot into a reverse motion for around 1 second. Last the robot coasted to a stop at the third point, and the course was finished. Image 5: Programming the robot to back up

C. Multimedia: media type="custom" key="686851"

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): There was only one main difficulty that was encountered in completing the challenge. It was the programming. When the robot has to make a wide right turn, it has to almost go in a quarter circle. It was hard to figure out the exact amount that the robot had go in order to stay on the line. Once the group had tried many times and it accomplished the task; the course was easily finished and completed. Overall programming is the hardest part of robotics for the pink panthers.

A. Description (Short Paragraph): Challenge four was one of the more difficult ones that had been assigned in class. To complete this task the robot had to follow a course made by the group. Consisting of 3 turns (130,120, and 90 degrees)and 4 straights (36,25, 40, and 30 cm)the robot took a lot of time to program. Eventually the group began to understand the NXT software better, and the challenge became easier. After around three class periods of hard work the robot made its way through the course.

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): There were many difficulties that were encountered during this challenge. Finding the right angle that the robot had to turn, and finding the right length that the robot had to go on each straight proved to be the most difficult problems the group had to face. Sometimes the sound sensor didn’t work, or didn’t reply, and other times one part of the robot might break. Determination and trial and error helped to overcome these challenges and make the robot succeed in completing the task.

5. DATE: 5/20/2008
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 to calculate the velocity would be to have the robot move at 30% power over a 70 cm distance. The robot went 70 cm in 6.18 seconds. To find the velocity you would solve the equation 70/6.18. a.

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. our strategy was to

Description of what made this task difficult for your group. The group found the NXT software very hard to understand and make do what they wanted it to do. Other than the hard time with the software, the wiki was also giving the group problems. The picture loading system on the wiki space was not loading the picture that the group made. Overall the only parts of the challenges that the group had problems with were the computers. The robot worked great and when the software was figured out, it was easily transferred onto the robot and the challenge was completed.

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)**this task was worked on collaboratively with the 3 Musketeers (Megan, Jordan, Kjersti)**  :: 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.

b. Description of what made this task difficult for your group. There was only one main difficulty for the group today. It was the software. Starting out on one computer, the robot was not cooparating. After this dilema the group moved onto to work on another computer and the task was on its way. The jobs were split up equally and the task was completed with only a few troubles in between.

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.
