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)=

Title of Challenge: Point Turn A. Description: The robot had to execute a perfect point turn. First, it had to go 25cm forward. Then it had to point turn to the left and back up 10cm. This was achieved.

B. Programming Code: Three move blocks were needed for this challenge. Picture 1: Point Turn Program

First, the robot was made to go forward one second at full speed. This made the robot move 25cm forward. Picture 2: Going Forwards 25 centimeter

Then the robot was told to point turn to the left (in the steering section) at full speed. The wheels were turned for 370 degrees instead of 360 degrees to achieve more exactitude. This made it make a complete 360 around itself. Picture 3: Point Turn to the Left

Last, the robot was told to go backwards during 0.6 seconds at full speed to go back 10cm. Mission accomplished! Picture 4: Going Backwards 10 centimeters

C. Multimedia: D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): It was hard to get the exact amount of time to reach 25cm/10cm was hard. Also, some difficulties were encountered to find how much the wheels have to turn to get a straight point turn, which is what led to 370 degrees instead of 360. It was possible to solve these problems by using a meter stick and timing how long it took to reach a certain length in centimeters as the NXT-G programming language does not give the option to move a specific length i.e. centimeters or inches.

Title of Challenge: Square A. Description: The robot was programmed to move in a perfect square. The robot would travel on one side then do a point turn and travel on the next side. It did that for four sides. B. Programming Code: Picture 5: The moving blocks Eight move blocks were needed for this challenge.

Picture 6: Starting on the first stretch First, the robot was told to go forward 10 centimeters. Since there is no centimeter option, the time it took to reach 10 centimeters had to be measured with a meter stick and a stopwatch.

Picture 7: Turn to the left Next, the robot had to turn to the left on the first turn. Instead of making the two wheels turn to go around the corner, we made only one wheel turn so that the robot would not slide on the floor. The wheel was told to turn for 305 degrees to make the turn.

Picture 8: Moving along the next line Next, the robot went forward for 1.4 seconds to reach the square's next corner.

Picture 9: Turn to the left The robot then repeated the same turn exact same turn as the other one.

Picture 10: Forward on the next side The robot went towards the next turn.

Picture 11: Turn to the left The robot made another turn.

Picture 12: Moving on the final stretch The robot went towards the last turn.

Picture 13: Last turn to the left The robot made its last turn and stopped. Mission accomplished!

D. Difficulties Encountered/How You SOLVED the Challenge: The hardest part of the challenge was getting the robot to turn the correct amount of degrees. The code was troubleshot until the turns were correct. It was also difficult for the robot to turn at the correct point and not go too far or too short. After the code was troubleshot, though, success was achieved.

Title of Challenge: Backwards square A. Description: The robot had to complete the square that it did in the last challenge only this time it will be traveling backwards. B. Programming Code:

Picture 14: The moving blocks Nine move blocks were needed for this challenge.

Picture 15: Moving backwards on the first side The robot first moved backwards for 1.9 seconds towards the first turn.

Picture 16: First backwards turn The robot turned backwards for 305 degrees.

Picture 17: Moving backwards again The robot moved backwards for 1.4 seconds to the next turn.

Picture 18: Another backwards turn The robot made the next backwards turn also 305 degrees.

Picture 19: Moving backwards on another side The robot moved backwards towards the next to last turn.

Picture 20: Another backwards turn The robot made another turn and was on the final stretch.

Picture 21: The last side The robot moved backwards on the final stretch towards the last turn.

Picture 22: The last turn The robot turned and came to a stop. Mission accomplished!

C. Multimedia: D. Difficulties Encountered/How You SOLVED the Challenge: The difficulties were the same as in the forward square. The turns were messing up and the robot would either go too far or too short. Also the wheels kept slipping. = = = =

Title of Challenge: The E course

A. Description (Short Paragraph): The robot had to move in an e shape and stop when it sensed the black line at the finish line. It was a pretty advanced course.

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. Picture 1: Overall Program Picture 2: Detail Program All we did for this program, is make a move block that makes the robot move at 30% speed for a VERY large amount of rotations. We then made it go forward next to a meter stick and timed how long it took the robot to reach 70 cm. We repeated this 3 times. b. Description of what made this task difficult for your group. No difficulties were experienced during this task. b. Description of what made this task difficult for your group. No difficulties were experienced during this task

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.
