Hi,

I am in search of a bluetooth controller like the wii nunchuck for driving my robot around. I need a Twist message as feedback from the controller. I am running Ros Indigo on Ubuntu 14.04 on a Raspberry Pi 2. Does anybody have experience with that and could recommend a controller and a package?

Edit 15.12.16:

I have tried to use the joy_node, but when I run "sudo jstest /dev/input/event15", I got this feedback: "jstest is not fully compatible with your kernel. Unable to retrieve button map! Joystick (Unknown) has 2 axes and 2 buttons. Testing ... (interrupt to exit)

jstest: error reading: Invalid argument" Is it possible to solve this problem?

I'm not familiar with that particular model of presenter. If you can find a Linux Joystick driver for your device, you can use it with the joy node

I used a similar "air mouse" remote on another Linux project. The device appeared to the Linux kernel as a standard keyboard and mouse devices. If that's the case with you're device, then you would want something like mouse_teleop.
