Zongpeng Yu’s Status Report 3/27

So we decided to make some changes to the servo subsystem. Instead of hooking the servo up directly to raspberry pi, we hooked it up to Arduino instead. The reason for this is because Raspberry Pi’s GPIO pins aren’t  able to  reliably read feedback PMW from the servo.  Attached is a video of servo spinning 90 degree each second. it is also capable from rotating more than 360 degrees if we want to thanks to it being a continuous servo. The library i used is from here:  https://github.com/HyodaKazuaki/Parallax-FeedBack-360-Servo-Control-Library-4-Arduino. Next step I will set up the serial communication between Raspberry Pi and Arduino so the GST(game state tracker) could send me the location where the servo should turn to.
