I'm using Ubuntu 16.04 on Nvidia TX1 platform, and I have the same error. Did you find out a solution yet?

Could you tell me how you solve this problem, please? Do I need to install any SDK before I install the ROS driver?

Hi, the only driver I preserved is a FOTONIC driver for Linux x64. I'm not sure if it's usable on Mac OS. I don't think

2016-05-30 17:19:03 -0600 asked a question Fotonic depth camera in ROS

Hi guys,

I'm now trying to use a Fotonic depth camera in ROS and the camera is not covered by ROS. They do have a Linux API and they already provide some SDK for me.

http://www.fotonic.com/product/fotoni...

It seems that I have to write a driver on my own, but I have no experience on this. Anyone has written this driver before? Or is there any where that I can learn how to start my work?

Thanks! You are right, after I installed sudo apt-get install ros-indigo-ros-control ros-indigo-ros-controllers It starts to work now!

Hello,

I'm a new hand using ROS indigo. Now I'm trying to simulate a segway (Stanley RMP210) in Gazebo and control it moving on the screen. I've downloaded these packages: cd ~/segway_ws/src

git clone https://github.com/StanleyInnovation/segway_v3.git

git clone https://github.com/StanleyInnovation/segway_v3_robot.git

git clone https://github.com/StanleyInnovation/segway_v3_desktop.git

git clone https://github.com/StanleyInnovation/segway_v3_simulator.git

Then I try to follow other tutorials and run: roslaunch segway_gazebo segway_playpen.launch luckily, a segway in Gazebo shows up. However, some error occurs:
