This week, I helped our group try to reach our MVP requirements.
One thing was trying to pick out components for the RC filter which was initially going to be 1.2KOhm resistor and a 2.2microF since this would yield a cutoff frequency of 60.29. However, with further testing, the amplifier fine tuned the signal enough without noise and distortion which allows no need for the filter. I further investigated this and documented the total harmonic distortion graphs that I found in the amplifier chip’s data sheet in the design report. However, it may still be in consideration to be used in the future as testing continues.
Since I was not in Pittsburgh when the robot chassis came in, I was unable to work and help on it. However, I continued to help by documenting the project in the design report, putting in the use case and design requirements, implementation, and such.
This week, I plan to construct the collimator and attach to the working speaker and amplifier apparatus to see if this will put out the fire as intended. I also plan to help on test the robot and integrating the speaker apparatus with the chassis.
