If you're looking for a cloud-based platform to help you program and monitor robot arms remotely, Jacobi Robotics is worth a look. The platform is designed to accelerate robot arm development and deployment with features like AI-based robot programming, remote programming and autonomous recovery. It supports multiple industrial robots and cobots and includes Jacobi Studio, a web-based tool for visualizing robot environments and motions, available in cloud and on-premises versions.
Another possibility is Replit. Although a cloud-based software development and deployment service, Replit is a full-featured environment for building and deploying software quickly with no setup or downloads required. It's got tools for online and offline collaboration, AI code generation and secure source code management. It's more general purpose than Jacobi Robotics, but Replit's flexibility could be useful for developers who want to incorporate robot arm programming into a larger software project.
