Right Face Activity Lab #2

1. What happened when you ran the program?
          -The robot make a º270 right turn.
2. Which motor(s) spun?
          -Only motor C spun.
3. What direction did each motor spin?
          -Motor B didn't spin. Motor C spun right, or forward.
4. Did the robot's body turn to its left or its right?
         - To the right.
5. About how much did the robot's body turn, relative to a full turn?
          - 3/4 of a turn.
6. This behavior is called a "swing" turn. Around what point does  the robot swing?
          - The robot swings around the right wheel.
7. Write a brief one or two sentence description of what each icon in the program "Swing Turn" does.
          - First block: move block. It makes the left wheel (port C) spin forward.
          - Second block: move block. It is programed to make the right wheel (port B) brake, allowing the stay completely still.
          - Third block: wait block. This block lets the robot only complete 2 wheel rotations.
          - Fourth block: move block programmed to make right wheel (port C) brake.
          - Fifth block: move block. The move blocks is programmed to make the right wheel (port B) brake.
8. The robot started at position A on the diagram shown here. It then turned in place until it reached position B.
     a. Can you tell which direction it turned to get to this position? Explain why or why not.
          - No, I can't tell which what it turned. It could be turning left or right.
     b. Suppose the robot turn to its left to reach position B. What fraction of a full turn did it make to get from A to B?
          - 1 3/4
     c. Suppose the robot turned to its right to reach position B. What fraction of a full turn did it make to get from A to B?
          - 1/4 turn
9. Consider the effects of some additional factors.
     a. How do you think different wheels will affect the robot's ability to turn? Does it matter?
          - Different size wheels would call for a different amount of rotations if I wanted my robot to go the same distance.
     b. Does the surface on which the robot is turning matter?
          - Yes, it could slip or get stuck on paper. My robot could stick to carpet more than it would stick to wood floors.
10. The robot in the given program turned right by moving its left wheel forward while holding its right wheel stationary.
     a. Could you also turn right by holding the left wheel stationary and running the right wheel in reverse?
          - Maybe.... its sounds logically possible.
11. What program blocks are different between the let turn and original right turn behaviors?
          - No blocks are different, but the direction of the first motor blocks are different. The wait block is programmed to recognize a different direction.
12. Could a left turn also be done with the backward-moving wheel idea from question 10? program your robot to make the backward-left turn.
          - sure
13. Describe the difference between the morion of a swing turn and a point turn.
          - The Swing Turn is a pretty literal description. It sort of "swings" on its right wheel. So if there was a line drawn on a surface, the robot would still be on that line when it did the swing turn, kinda like the right wheel was attached to the line.
When my robot did the point turn it sort of revolved around in a circle. If I put a quarter underneath the my robot before it turned the quarter would be in the same position under the robot after completing the point turn.
14. Describe a situation where:
     a. A swing turn is more useful than a point turn.
          - A swing turn would be preferable in a situation where something was coming up behind it and the robot had to turn and also get out of the way
     b. A point turn is more useful than a swing turn.
          -  Point turns are the bomb-diggity when my robot has to turn around and face its opponent stay in the line of fire, and being able to totally destroy the enemy!
Just kidding. That would be pretty useful, but if my robot was in a very small area, like perhaps searching for a lost kitten that into a pipe, it would be easier to turn right around than to flip around.
