Digital cameras are being widely used in robotics in 3D scene reconstruction, simultaneous localization and mapping (SLAM), and other applications, which often require real-time video stream from multiple cameras. In a case of a mobile robotic system with limited hardware capabilities performance issues may arise. In this work we present a real-time video streaming robot operating system (ROS) package for our crawler-type mobile robot Servosila Engineer, which has four on-board cameras. Compared to OpenCV based solution our package demonstrates less resource consumption.
