WEEK 9 

DATA COLLECTION FOR THE FINDING THE ANGLE

For the data collection, all the data that had been received from the Arduino IDE was then recorded. The data came out in the form of angle in degree and the time take in millisecond is shown at the serial monitor. All the data from the serial monitor is then transferred to the Excel to make a chart/graph.

measurement

Graph shows the angle of the seat from the IMU sensor

While for the stroke length of the actuator motor is measured by using a measuring tape placed near the stroke length of actuator motor is lengthen.

Example of how the stroke length is measured

All the above experiment setup is to find the angle of the seat and also to compare from the manual way by using the protractor and easy way by using the IMU sensor. Both method are used for this experiment to compare the result that was taken and to identify either both method can be used to take an accurate reading and measurement in the future.

The comparison had been made after getting the results from both ways. Here are some of the result obtained from the experiment:

Comparison of the result obtained

From the above table 5 shows the comparison between protractor and IMU, clearly shows that the result were slightly different from each of the results obtained. This shows that both manual and IMU ways can be used to find the angle as there are not much of different between both results.
