Field of View

1. i) Yes they follow a gourd like pattern
ii) it detects near and far
2. i) 60 cm
ii) directly in front
3. i) yes, about 35cm
ii) yes, it will avoid it
4. 2cm
5. 10cm
6. 1:5
7. i) It follows the same pattern, its just smaller
ii) Its smaller
iii) yes
8. i) every 1 cm on the paper represents 5 cm in real life
ii) 4.4 cm
iii) 11.5 cm
9. i) directly in front
ii) it was 12 cm from the front of the sensor on the graph paper
iii) 60 cm
iv) 62 cm directly in front of the sensor
10. i) it gets smaller and then wider in the middle
ii) 50cm
iii) it needs to use different sensor applications to detect something father away rather than closer and visa-versa because it takes different power reading are needed to detect things at different distances, just like our eyes shift.
11. It sent out a noise which spread out in a circular patter and then began to fade out when it sent out a second, louder, noise which also spread out in a circular pattern and then faded out.
12. First you need to draw a line on the floor. Then place the robot with the ultrasonic sensor on the front of the line. Get a can like object. Place it on the other end of the line. Slowly begin to inch it forward until you get a steady reading on the sensor. mark down that pint. Then use a yard stick to measure out every 10 cm on the line up to your point. Take your can and put it to the right of the 10 cm point. slowly inch it back toward the line until you get a reading. Do the same for the left side of the line. Then repeat the steps for every 10 cm point up to your original point. Finally find the scale between the actual distance and the distance on the graph paper. Use this scale to graph all of your points.
13. i) 52 cm directly in front
ii) at the 40 cm mark the point are about 31cm apart
14. i) 2:25
ii) at 170 cm directly in front
iii)at 100 cm the points are about 115 cm apart
iv) no
15. i) 62cm
ii) .0018 s
iii) .0018 s
iv) .0036 s
v) .0019 s one way, .0037 s total
vi) Its quite fast.
