Title of Challenge: Challenge 1
A. Description (Short Paragraph):
The first thing that was done by the robot was to move forward 25 cm. Then it was to make a 180 degrees point turn to the left. Finally it was to move backwards 10 cm and to stop. This all only took about 4 to 5 seconds to complete.
B. Programming Code (Picture and Written Explanation):
Jmechanic'simage.jpg
The programing code tells the robot what and where it is to go. It can tell it to say something out loud or display it on the screen. The first block had all of the wheel go straight and told the robot to go forward 25 cm. Then the second block had the back wheel turn 180 degrees causing the robot to do a 180 degrees turn to the left. Then the last block once again had the wheels straight, which told the robot to go back 10 cm. Each block tells a different action so looking at this now there are only three block so this is not a very complex movement code. There are three little icons at the bottom of the cubes, the first one shows that the robot is to move forward. The second one tells how much power. The third one says the amount of rotations that the wheel goes around on the power. This goes for all the blocks after this. Though the information will change there is a similarity in them. For the first block there was 1.5 rotations of the wheel at three fourths power. The second block says to go left 180 degrees at three fourths power with one rotation. Then finally the last one says for the robot to go backwards 10 cm with half power.

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

Since this was the first challenge it was not that difficult because the robot only had to move forward 25 cm, make a point turn and then go back 10 cm. Since this is all that had to be completed there really weren’t many difficulties that had to be solved. Most likely the next challenges will be much more difficult. The one hard part about this challenge was estimating how long it would take for the robot to got 25 cm and then how long it would take to back up 10 cm.

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

A. For each challenge you must write a short description of the challenge using complete sentences. Please write in 3rd person, scientific writing.

This challenge included the robot moving in a square. First the robot had to go forward about 63 cm and then it had to make a 90 degree turn. After the turn it should repeat and the same thing for the next part and then it should repeat one more time to complete the entire square.

B. This is where you should include your programming code by including screen screen shots.

Picture 2: Code for Challenge 3

The code for challenge three is kind of confusing. The first thing that appears is an orange loop. This caused the move parts of the code to repeat four times. The second part of the code was one of the move parts. It had 3.25 rotations, which caused the robot to go forward 63 cm. the second block caused the robot to make a 170 degree turn. Then the last thing was the end of the orange loop part, which ended the whole code.

D. For each challenge you should provide a written explanation of the difficulties encountered with the challenge.

Some difficulties that were encountered for this challenge were that the angle measurement for the turn was messed up the first few times. Also a problem for the first couple of tests was that the robot ran a little extra time over the line. The biggest problem for the robot was the angle measurement for the turning. When the robot ran a little over the line that was not as big of a problem. Other than the angle measurement there was not many other problems.

Title of Challenge:
A. Description (Short Paragraph):
This experiment involved the robot to go forward turn then back up. Once it backed up it was supposed to say something and stop.
B. Programming Code (Picture and Written Explanation):

Picture 3: Picture of Programing code

In this code each block again tells the robot to do something different. The first block told the robot to go forward for 3.15 rotations. Then the second one told the robot to turn ninety degrees to the right and then to go forward for 2 rotations. The third cube told the robot to say, “Have a nice day!” while it backed up for 2.6 rotations. This was not a hard movement code because there was only four blocks. What made this a hard task was experimenting with the different types of distance for the rotations. Block one’s movement was done at three fourths power and so was block two’s movement. Block four was the same at three fourths power.

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph):
The first problem that was encountered was that the turn wasn’t going sharp enough, and therefore it was not staying on the line. First thing that was done was to add more turn, but then it was turning all the way around. Finally it was come to a solution to keep the turn to stay as it first was with duration of 2 and a power of 75. Then we change the duration of going forward to 3.15 this now the turn was able to stay on the line and the project was complete.

Title of Challenge: Challenge 4

4. Create a Basic Obstacle Course and Program Your Robot to Navigate It!

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):

Introduction to Challenge Four
In this challenge the task was to create a original course that the robot was to run. The course created is as follows: first a sound sensor had to placed on the robot because it had to sense a sound to start; then the robot was to go 20 cm forward then to make a 110 degree turn to the right then to make a 35 degree turn to the left. Then it was to make a 90 degree turn to the right and then it was to continue for another 30 cm. Then it was to make a 90 degree turn to the right and then to continue for 28 cm. Then it was to make a 360 degree turn to the right and then to continue on for another 47 centimeters to the finish line and to finish.

B. Programming Code (Picture and Written Explanation):

Picture 5: Programming Code continued for Challenge 4

In the beginning of the code there is a microphone. This shows that the robot will start the course once a clapping noise is sensed. After that there is another block this shows that the robot is moving forward 20 cm. The second block has the robot making a very sharp right turn and then the next block is showing it turn back to the left. After that another block is shows that the robot is turning to the right so that it straightens up for the next block. The next block then has the robot going forward 30 cm, and then the robot was to make a very sharp 90 degree turn to its right. After that it was then to continue for another 30 cm. once it had gone 30 cm it had to make another 90 degree turn to the right, and then move forward about 28 cm. Then the final stage was for the robot to make a 360 degree turn to the right. There was one more part to the obstacle course, but that was unable to be finished.

D. Difficulties Encountered/How You SOLVED the Challenge! (Paragraph):
One of the first problems encountered was the second turn it was always turning too far. The more turn added the more it messed up, so it was decided to change the course so the second turn change to two right turns. After several tries these right turns were accomplished. Next thing was the full circle, but with little time it was also changed. Now it is not a full circle, but the robot still goes around in 360 degrees. With a couple adjustments all of the problems were solved.
