Servo Abstractor - Python

Sort of redundant to give these functions their own file, but this program takes the basic servo movements from the servo controller file and combines them to automate walking functions.

TARS Runner - Python

Run this file in terminal on your onboard computer to initialize TARS. This file handles communication with the bluetooth remote.

Servo Controller - Python

Handles basic movements of servos in TARS. Communicates with an Adafruit PCA9685 servo driver to control the servos.
