'''Design Consideration (13/6/17):'''

''KROG Robot (sensors/modules)''

*Microphone + Gain amplifier => audio detection and preparation for filtering/analysis
The particular module combines a simple microphone with a gain amplifier to make it easier to perform a frequency analysis on the input data. Our goal with this device is to detect the presence and frequency of an audio input (music) in order to tailor the "dancing" response of KROG.

*Communication chip => communication between subject and robot.
For this communication chip, I propose using the XBee Pro S1 chip.
I have more familiarity with ZigBee technology than with other communication technologies.
The advantages of XBee include: low power consumption, sufficient range (up to 10m), closed network.
I am open to learning other technologies, though I believe Bluetooth and WiFi would be impractical for this project (due to range and security protocols).

The communication module will be used to communicate the accelerometer/gyroscope information to the robot. This is to allow the robot to mimic the movements and speed of the user.

*(potentially) Ultrasonic sensor to detect proximity of subject, objects, or Occupational Therapist (OT).

''Subject (sensors/modules)''

*Communication chip => communication between subject and robot.

*MPU 6050 Acclerometer/Gyroscope => detect movement of subject (to be sent to KROG)
