Image 2: Block for the point turn These are the basic instructions the robot was given to make a point turn

In the point turn experiment mind storms was used to program the robot to go 25 cm and turn around and back up 10 cm in the same direction it was going before. In the program one of the blocks was used to move forward for 2 seconds. The second square made it turn 420 degrees in the unit it was using and made it face the opposite way by now. The third square made it go in reverse and go back 10 cm. There were a lot of difficulties in timing this challenge right.

media type="custom" key="654537" video 2: point turn video

Some difficulties we had during this was to get all the timing right. If the timing was right, or the adjustments of degrees weren't rite the whole thing wouldn't work. We had difficulties specifically on the amount of centimeters that we had to travel. We would need to constantly fix that and would need to do it multiple times. This made us slower than other groups, and fell behind. We eventually caught up by thinking more reasonable numbers, and used more of a strategy by saying if that number was too big we would go down a little so we wouldn't overdue it. We could've easily changes the power of the motor, which would've made it easier.

<span style="font-family: 'Comic Sans MS',cursive">**4/18/08** Instructions: Your robot must follow the square drawn on the floor at the front of the room. In this challenge the robot has to follow the course on the floor in the front of the room. The robot goes forward an amount of space once the sound starts to inform it that it is suppose to start. After that it takes a 90 degree point turn right and goes forwards again the same amount. It takes another point turn right 90 degrees, goes forward, and takes another point turn and goes forward. After these turns and twists, the robot will have traveled in a square. <span style="font-family: 'Comic Sans MS',cursive; color: rgb(255, 5, 5)"> media type="custom" key="685867" Video 3: Doing the Square <span style="font-family: 'Comic Sans MS',cursive; color: rgb(255, 5, 5)"> Image 3: Programming the Square

<span style="font-family: 'Comic Sans MS',cursive; color: rgb(255, 5, 5)">

Some difficulties of programming the robot to run in a square, was a lot like the other challenges that were done. A lot of troubles were with the distance it traveled, and the turns it had to make. The robot would adjust the turns, and they wouldn't be the same as all the others. Another problem was adjusting the turns to a new robot, the robot that was used was already adjusted, and was close to being done. The group then had to switch the angles and adjust it once again after they could not find the robot they used.

<span style="font-family: 'Comic Sans MS',cursive">3. Backing Up
<span style="font-family: 'Comic Sans MS',cursive">**4/18/08**

In the front of the room a path was made that the robot needs to follow. The robot follows the path, and while following the path it goes forward takes a 90 degree right hand turn. After it takes the turn it starts to play a sound that will begin when it stops. While it is playing the sound the robot will back up into the bay, or area marked. Once it has done that part of the challenge, it will stop and the challenge is over. <span style="font-family: 'Comic Sans MS',cursive; color: rgb(255, 5, 5)">

<span style="font-family: 'Comic Sans MS',cursive">Image 4: programming blocks for Backing Up This is the programming of the whole program together. It starts with the sound which is the picture of the microphone. Then it moves forward, and makes a curving turn. After that, the robot backs up. <span style="font-family: 'Comic Sans MS',cursive"> <span style="font-family: 'Comic Sans MS',cursive; color: rgb(255, 5, 5)"> Image 5: Variables for curved turn This is the code that was used to make to robot turn in a curving motion. Which was harder then a point turn. Some variables that can be adjusted are the direction, how much of a turn it will make, the power, how long it will go for, whether it will break or coast to a stop after the turn was done, and what ports the wheels are going to be connected to.

Some difficulties during the experiment was to make the robot have a good curving turn. The robot would make the turns hard because it would change from day to day. If the challenge was not finished that day, a new robot would be taken or the same robot was taken but did not run the same as the day before. The robot also had difficulties with backing up into the bay or marked area.

A difficulty with this project is that the particular kit we were using was not working properly. We got a new kit, one not being used, and opened it to find that all of the wires were in the wrong places, and the sensor connectors were all different kinds, kinds that couldn't be connected well to the sensors we were using. we fixed the problems, and put the sensors and wires into the right place
 * Difficulties**

Another problem with this program is the sharp 70 degree turns. These turns are hard to make the robot maneuver these turns because they are so sharp and the robot cant turn so quickly. The power was adjusted, and then the idea to turn off the left and then right wheel respectively to make the robot sharply turn left and right came up. After many adjustments, the robot was extremely close to finishing the course.

Another difficulty that was faced was one of the members accidentally dislodged the robots left wheel. This caused a major problem because it made it so that it was required to redo most of the angles of the turns. Also it had such sharp angles which made it very hard. Also it was hard to get the robot in the same exact starting place each time. = = = =

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.

Description of what made this task difficult for your group.

Something that made this task difficult was making the table. We did not know how to make a straight line so that we could predict what it would be with 60% power. All the other things like programming, was easy to do.

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.
