For remote control, we get the controller from PiHub, and used the python library “approxeng”.
Thanks to the team who contributed to the library and the documentation of the library, which made our job a lot easier.
We tried different key combinations. And among us, we have divided viewings on which key to use for what, including the most essential forward/backward left/right controls. That was because we use different settings when playing games, and ended up in different habit.
Anyway, the good news is that we finally agreed on the set of controls, and to seperate the left/right turn controls from the forward/backward controls. And we use different shaped keys to enter into different running mode.
PS:
You can see the detailed “approxeng” library reference and examples on this page:
