Field of View

1.
i. It made a snowman figure.
ii. It represents the area that the sensor can detect objects. It detects near and far in a wide range, but not as well in the middle.
2.
i. 60 cm
ii. 62 cm away from the sensor, directly in front
3.
i. The widest detection range is bigger than the robot's width.
ii. Yes. the NXT is narrower than 35 cm, so if an object is at the edge of the range, the robot will not run into it.
4. 2 cm
5. 10 cm
6. 1:5
7.
i. The graph is the same pattern as the actual dots. We can see that the robot is smaller than the detection range.
ii. The size of the dot pattern is smaller.
iii. Yes. It is the same information, just smaller.
8.
i. The scale factor means that every one centimeter on the paper is equal to five actual centimeters.
ii. 4.4 cm
iii. 11.5 cm
9.
i.  directly in front of the sensor
ii.  12 cm away
iii. 60 cm
iv. The farthest it can detect is 62 cm right in front of the sensor.
10.
i.Yes, at about 50 cm, the robot's side ranges narrowed.
ii.50 cm
iii. Different amounts of frequency of the waves are needed to detect something farther away than something closer.
11. The detection area was in the shape of a circle. As it got farther away, the rebounded waves got weaker until it switched to distance mode, where it had the same circular pattern.
12. We put the sensor on a flat line on the floor. Looking at the sensor readings, we saw how far away the robot could detect an object. Then, at intervals of 10 cm (10,20,30,40,50, and up to your point of farthest detection), we found how far to the sides the sensor could detect an object. We then recorded the points on a scaled graph.
13.
i. It was 52 cm, directly in front of the robot's sensor.
ii. The widest detection part is about 31 cm wide at a distance of 40 cm away from the robot.
14.
i. 2:25
ii. It is about 170 cm, right in front of the sensor.
iii. 115 cm wide
iv. No, it doesn't have the gourd like shape, indicating the mode switch.
15.
i. 62 cm
ii. .0018 seconds
iii. .0018 seconds
iv. .0036 seconds
v. .0038 seconds
vi. They are really fast. It has to be able to detect to the hundred thousandths place.
