I am trying to use the playstation controller with my GoPiGo, I am running into a issue. I am using the pi3 and operating on Raspbain for robots. Followed the github readme direction, but when I run the gopigo_gpg_example i get the following error: no mule named ps3. Any ideas??? Can it be my controller as it is about 10years old. The controller is a PS3 dualshock3
