Jack's Field Of View Experiment

The purpose of this experiment is to determine how much area in front of the robot is covered within the range of the reading of ultrasonic sensor.

Material

• Meter sticks (plus minus 0.05cm)
• Black and white tape (or any combination of tape with different colors)
• Aluminum Can
• Scissors
• Taskbot with Ultrasonic Sensor

Procedure

1. Place a meter ruler directly straight in front of the robot.
2. Along the ruler line, place a long piece of white tape.
3. Using a marker, mark a line on the tape for every section of 10cm wide (starting from 0cm, 10cm, 20cm...90cm)
4. Make sure there are no obstacles in the direction that the robot is placed since it will affect the sensor reading
5. Place the aluminum can so that a surface area is directly in front the the robot and situated at the 10cm mark. Move the robot towards the left side of the tape while making sure that it is directly perpendicular towards the 10cm mark. Displace it until the robot is on the boundary of registering a value and "????????". Mark the position of the robot using a black tape. This should be applied to the right side of the robot as well.

6. Repeat step 5 for all the increments on the tape ( 20cm, 30cm...80cm)
7. If the robot cease to register any object on the 80cm mark (it could be more or less depending on your ultrasonic sensor), move the can closer towards the robot until it register a value, mark that section using a tape.
8. Record the position of all the black tape on a sheet of recording paper. This could be freely scaled down to any extent, as long as the person who records the data remembers the scale. (In my case, 1cm on my recording paper is equivalent to 10cm in real life)
