I delved into this exact area in the last startup I was at. I worked pretty extensively with Kuka 6 axis industrial robots and spent a lot of time programming them as well as integrating them with our custom hardware. Totally agree that there is a big opportunity for a unified software layer on top of all this hardware.

The system I ended up building allowed users to monitor the robot from the cloud, including telemetry such as end effector sensors and axis positions, as well as uptime. It also allowed steaming tool paths from the web platform to the robots directly with appropriate safety measures such as manual intervention required to start it. Would love to generalise this sort of thing and create a turnkey solution that allowed people to focus on solving their actual robotics problems, not spend all their time glueing together disparate components.
