How to control AR4 with joystick based on robot-viewer

[gabboraron]

Hi, I'm a newbie in robotics, so probably it's my bad, but can you please give me a short description, of how can I start using it with AR4 to teleoperate the robotic arm with joystick?

Here is what I understood from your videos:

1. I have to install on an rPI the servos-site
2. connect the rPI to the robotic arm
3. connect the xbox controller to the host machine where I run the robot-viewer
4. connect the host to the rPI (how??)

What am I missed?
