=I. Grant (L) Thomas(E,C)= =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: 4/9/2008
Title of Challenge:Beginner Maze A. When a hand is clapped,the Robot must go forward 50 cm, turn left, go forward 40 cm, turn 90* left, go forward 30 cm, gradually turn left, detect a black line and stop. B. C. Multimedia media type="custom" key="668579"

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): Some difficulties that we encountered included; the light sensor was not close enough to the ground, therefore it did not detect the line. The setting on the ligh sensor was told to stop at white, not black, so whenever it saw the floor it stopped.

Backing Up
Instruction: Your robot must follow the path drawn on the floor at the front of the room. The robot will go forward make a right hand turn (90) and then back up into a "bay" while making noise. See the picture below

Title of Challenge: Point Turn A. Description (Short Paragraph): The idea is to get the robot to move 25 centimeters, perform an 180 degree point turn, and then move 10 centimeters backwards. B. Programming Code (Picture and Written Explanation): For our programming code we used 3 move buttons. The first goes forward 1.6 rotations, and when measured it is 25cm. The second uses the steering control to make it a 180 degre turn C. Multimedia:media type="custom" key="668559" D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph): Some difficulties we encountered were the wheels being in the wrong ports so that when we went to move only one wheel moved. To make up for this we had to change the ports of which wheels were affected

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. The robot was to go 70 centimeters and the group was to measure the time it took. the velocity of the robot was 8.8496 cm/s forward. b. Description of what made this task difficult for your group. This task was not difficult at all for our group. the only difficulty would maybe be that it was hard to determine 70 cm.

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. The group was to make the robot get faster and faster over 1 meter. b. Description of what made this task difficult for your group. This challenge was again not hard at all. The only challenge was getting it to 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!)

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. the group was to measure the distance and the time and then divide them. We got 12.03 cm/s forward for our velocity. b. Description of what made this task difficult for your group. this was difficult because it was hard to figure out what to do with the numbers, but our group did it in the end.

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. the group was to make the robot go 1 meter on 20, 40, 70% power. unfortunately our group did not make it to the graph, but we have the data here. 100/20.38=4.9068 cm/s on 20% power 100/8.79=11.3766 cm/s on 40% power 100/4.65=21.5054 cm/s on 70% power

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

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.
