There are several ROS package services available online, each offering unique features and pricing plans. ROS Development Studio (ROSDS) is a web-based IDE that allows you to create, edit, and run ROS packages on simulated or real robots. Additionally, users can learn ROS through tutorials and courses, and join online events and challenges. ROSHub is a cloud platform that enables users to build, deploy, and manage ROS packages and applications. You can also connect your packages to various sensors, actuators, and devices with ROSHub, as well as monitor their performance and status through web dashboards. The Construct is a web-based simulator that helps you test and debug your ROS packages on realistic 3D environments. It also provides courses and projects to help learn ROS, as well as a library of pre-built ROS packages and models. To use any of these services, you need to create an account and follow the instructions on their websites. From there, you can upload your existing packages or create new ones using the web interface or command line. You can also browse and download packages from other users to run them on your own robots or simulators. Furthermore, you can modify or customize your packages as desired before sharing them with others if desired.
