This week I performed the same calibration technique as the last time with a few precautions. I timed the measurements to make sure that there was a roughly equal number of data points in each. I also made sure that nothing else passed through the view of the receiver during measurements. This new data set is more consistent but has an outlier. The plots show that there is no correlation between signal strength and angular orientation of the calibrator. This set also indicates that the 100cm measurements had a stronger signal. This might be caused by interference with the receiver that occurs when the calibrator is placed too close.
The outlier is the 180 degree, 100cm measurement. The other measurements have signals within the same range between 0 and 50Hz which is reasonably precise. Yet the 180 degree, 100cm measurement still follows the trend that the 100cm measurements have stronger signals.
In the coming days I will meet up with Dr. Hassel to further interpret the plots. I will also begin to familiarize myself with the arduino that Jonathon Farrell had created during the summer of 2016. His blog, detailing the setup, can be found here: http://sienaviper2016.blogspot.com/
Once I am competent in implementing the motor controls on a smaller motor I will move on to the motors for VIPER.
