K9 Robot

Added audio that runs on internal battery. Bought a speaker and amp from Amazon and installed in the robot, seems to produce much louder sound which is nice though I'm hearing a lot of feedback/noise. Probably going to add a copper shield around to reduce interference. (Likely caused by the motors or background noise). In this implementation a hole was cut out of the base for the sound to travel out of the robot without it sounding muffled. This was added as in previous times it was difficult to hear the self contained "Jawbone mini"  that was used before. 

Added a photo of K-9 with the 3D printed metal ears.
