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.

Title of Challenge:
A. Description (Short Paragraph):
The robot must first move 25 cm forward. Then do a point turn to the left for 180 degrees. Finally the robot mus move back up 10 cm.
B. Programming Code (Picture and Written Explanation):
Robot_Program_1.jpg
The first block in this sequence makes the robot move forward 25 cm. The second block in the sequence tells the robot to make an 180 degrees turn to the left. Also the third block in the sequence tells the robot to back up 10 centimeters.

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph):
Some difficulties that were experienced in this experiment were that the back wheel was not straight when the robot started moving. Other difficulties that were experienced was that it was difficult to get the robot to turn the exact amount of degrees. It took numerous tries to get it right, and then the robot would mess up the next time. This was the hardest challenge for group 11.

Title of Challenge: Square Challenge
A. Description (Short Paragraph):The robot must follow the square drawn on the floor at the front of the room. The length of the sides are 62 cm.
B. Programming Code (Picture and Written Explanation):
Robot_Program_2.jpg
The first block in the sequence makes the robot move forward 62 cm by making the wheels turn 3.444. Also the second blcok in the sequence makes the robot do a 90 degree bank turn to the left. The next blocks continue the first two actions three more times in order for the robot to complete a full square.
C. Multimedia:

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph):
Most of the difficulties that were encountered in this expirment happaned on the turns. If the degree of the first turn was off 5 degrees, then on the second turn the turn will be of 10 degrees, and on the third turn it will be of 15 degreess. So the degrees on every turn had to be exact or else the robot will not make a perfect square. Also some of the later turns in the sequence had to have a greater degree of turn because the earlier turns were off.

Title of Challenge:
A. Description (Short Paragraph):
For the thrid challenge the robot must move forward 52 cm then make a banked right turn. After the banked right turn the robot mus stop at a 90 degree agle from the original path. THe robot must then continuously play a sound while backing up for three seconds and come to a stop.
B. Programming Code (Picture and Written Explanation):
Robot_Program_3.jpg
The first block in this sequence makes the robot move forward by making 2.889 rotations of its wheel to follow a 52 cm path on the floor. The second block in the sequence tells the robot to make a banked right turn and come to a stop. When the path splits into two parts one part tells the robot to play a sound on a loop for the remaining of the robots actions. The other path tells the robot to wait for 1 second before backing up for three second.

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph):
The first problem in the programming of the third challenge was figuring out how to have the robot make a sound while backing up and not disrupting the backing up. So the use of looping was used in the sound on a second bracket at the same time the robot backed up. The
second problem in the programming was trying to get the measurements exact. When the first banked turn was adjusted it changed the outcome of the second reverse line. One of the major problems was the back wheel of the tri-bot. it caused many different variables and made performance of the tri-bot less consistent. the way to solve this is to set the wheel to center every time.


DATE: 5/5/2009

Title of Challenge:
A. Description (Short Paragraph):
In this challenge the robot must stop after the sound of a clap. The robot must them move forward 40 cm by having it's wheels make 2.22 rotations. The robot then makes a 90 degrees left turn and moves forward 27 cm before making a 29 cm banked turn to the right. The root then travels 48 cm or 2.667 rotations forward before making a full 360 degree spin then continues 16 cm forward. The robot then uses the ultrasonic sensor to sense a binder then stop.
B. Programming Code (Picture and Written Explanation):
Robot_Program_4.jpg
The orange box at the beginning makes the robot start when it hears a clap. The next block tells the robot to go forward 40 centimeters. The third block makes the robot make a 90 degree left point turn, and then the fourth block tells the robot to move 27 centimeters forward. Then, the robot makes a 90 degree bank turn to the left. The sixth block tells the robot to travel 48 centimeters forward, and the seventh block makes the robot make a 360 turn to the left. The two blocks make the robot go forward 16 centimeters, sense the binder in front of it and stop.
