1. Point Turn
Instructions: 25 cm forward, point turn to the left (180 degrees), back up 10 cm

DATE: 4/8/2008
Title of Challenge: Point Turn A. Description (Short Paragraph):

In the Point Turn challenge, the robot must go 25 cm forward, then making a 180 degree turn. After it turns, it must continue on the same path, now going backwards, for 10 cm.

B. Programming Code (Picture and Written Explanation):

Picture 1: Programming Code For Point Turn

First, we programmed the robot to go forward 25 cm (shown in the first box). Then we programmed the robot to do a 180 degree turn to the left (shown in the second box). Then, in the third box, we made the robot go backwards 10 cm, and then stop to end it.

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph):

The difficulties that we faced as we did this challenge was making the 180 degree turn. While we were trying, it turned more than 180 degrees, causing it not to back up in a straight line. Also, at the beginning, the robot went way more than 25 cm.

2. Square
Instructions: Your robot must follow the square drawn on the floor at the front of the room.

A. Description (Short Paragraph):

The robot must go around in a square, which has sides the length of 61 cm and all right angles.

B. Programming Code (Picture and Written Explanation): Picture 2: Programming Code For Square Course

This is the code to make the robot follow a square. The first block tells it to go forward a certain distance. The next one tells it to turn 90 degrees (180 degrees in the program for a point turn). This is done over 4 times.

C. Multimedia:

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph):

The main problem was the making the robot do the point turn exactly. Some of the time, the robot would not turn enough, and other times it would turn too much. This probably varied because of the different robots. By, the end, we got it to go in the square perfectly.

3. Back-Up Turn
Instructions: Your robot must follow the path drawn in purple marker on the floor.

A. Description (Short Paragraph): The robot must do a slow, curved turn, then making another turn so the robot will be able to move backwards on the ending line. At the end, the robot must make a noise to tell that it has completed the course.

B. Programming Code (Picture and Written Explanation): Picture 4: Programming Code For Back-Up Turn

C. Multimedia: media type="custom" key="683953" Video 2: Robot Maneuvering Back-Up Turn Course

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph):

The first difficulty was making it follow the curve. If the curve was wrong, it would not back up on the straight-away. Also, the robot would not turn the amount it needed to get to the straight-away

4. Our Own Challenge
Description: The robot must follow a course created by the group.

Instructions: 1.) Using tape create a basic obstacle course. It must contain three different turns (any type of turn- point, gradual, etc.) and involve sensing a sound to begin the course (sound sensor), and coming to a stop once it recognizes the finish line (a black line- sight sensor). 2.) You will need to modify your robot to have both a sound and sight sensor. 3.) Draw an image of your course in OneNote and include it in your wiki entry (Snip It). Your drawing should include measurements (in metrics) such that anyone could re-create. You will also want to photograph it or record a video. 4.) Complete this challenge just as you would any other in the wiki. You must remove all tape from the floor at the end of the class period.
 * Fold both end of the tape for easy tape removal.

A. Description (Short Paragraph):

We made our obstacle course to the difficulty we thought that we could complete. We had the three 90 degree turns, we had the sound sensor starting the robot, and we used the light sensor to end the course. It first went forward, then made a right point turn, then made a left point turn, and then made another left turn. Then it had to back-up and stop on the black line using the sight sensor.

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph):

We went through many difficulties in completing this challenge. The first one was getting the 90 degree turns actually turn 90 degrees. After we got that solved, we had to get the light light to recognize the black line. Overall this challenge perfect for our group because it was not too difficult and it wasn't too easy either.

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.

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

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.
