The ROS Wrapper for Intel RealSense Devices provides a ROS nodelet interface between the camera and the ROS system. Intel updates this ROS package on a fairly regular basis, which could lead to API version mismatch errors. When this happens, the camera (sometimes) works fine on realsense-viewer but any code using the RealSense nodelet fails to compile.…Read more Updating the RealSense nodelet

When the RealSense stops connecting
The RealSense D435 RGBD camera is generally very robust and reliable. It can however fail to connect and display the image and depth frames. When this happens, hardware notification errors appear in the realsense-viewer software as shown below. Usually this is caused by a connection issue, such as trying to use USB 2 with the RealSense,…Read more When the RealSense stops connecting
Integrating the Intel RealSense D435 with ROS
The Intel RealSense D435 is the latest RGBD camera available from Intel, and is an upgrade from the Intel R200 camera already discussed in a previous post. The D435 is a stereo depth camera that is designed to work both indoors and outdoors. The 3D reconstruction is constructed using active Infrared (IR) stereo. The camera is…Read more Integrating the Intel RealSense D435 with ROS
Getting started with ROS nodelets
ROS nodes communicate using TCP/IP protocol which might be too slow for applications that require sending large amounts of data (like 3D point clouds or video streams). For processes running on the same computer, a pointer to the data can be sent rather than sending the data itself over TCP/IO. The Intel RealSense Robotics Development…Read more Getting started with ROS nodelets
