Python Code and other info for a 4 wheeled robot controlled by a Raspberry Pi.

I'm new to robotics and Python, but not to computers and programming. I'm definitely learning a lot.

##Updates October 29, 2015

• Rover now uses move2.py to move forward and backward 2 seconds using 4 wheels. An improvement over move.py which is monolithic, move2.py includes functions moveForward(intTime) and moveBackward(intTime) to move the rover for a period of seconds. My first Python functions!

• wrote moveturn.py to test turning
• purchased a Mental Beats battery back for untethered greatness!
• seems not to have enough power to turn
• added turnLeft(intTime) but it is actually a right turn. Will fix it later.
• Pin 7 controls left motors in forward direction
• Pin 11 - Left motors in backward direction
• Pin 15 - Right side motors forward
• Pin 13 - right side motors backwards

• Fixed left/right turn function names
• Turns appear underpowered on carpet, but probably need to by a Pi Servo Hat as the Raspberry Pi is known to have inaccurate PWM signals.
• Created rover.py as a module to store movement functions.
• Wrote backforth.py to use command line argument for number of repetitions and it imports rover.py
• square2.py moves the rover in a square where the robot travels 2 seconds in each direction. Slight problem with turns but may be fixed with Pi Servo Hat.
