Right Face

1. It turned to the right but it went too far.
2. The left motor ran.
3. The left motor spun forward. The right motor stayed still.
4. It turned to the right.
5. About 1/3 of a 360 degree turn.
6. It swings around the right wheel, which isn't moving.
7. Run c motor, tell b motor not to move, wait 720 degrees, then stop c then b motors.
8. i) It turned right 90 degrees or left 270 degrees. You can tell because its relation to the position of the arrow.
ii) 3/4
iii)1/4
9. i) To reach the same position the degrees will have to be greater.
ii) Yes it needs traction and uneven ground could have significant effects.
10. i) yes
ii) done saved as reverse swing turn
11. The first block was set to stop instead of forward, the second block was set to forward instead of stop, and the wait block was set to motor B.
12. yes. done saved as reverse left swing turn
13. It is faster and it moved farther. Swing turn: one motor moves, 1 stays still. Point turn: both wheels move.
14. i)A swing turn is more useful for sharper turns.
ii) The point turn is more useful for when there are obstacles in the way. Then the axis of rotation is in the middle of the robot so it won't hit the object.
