This sounds awesome! Can you tell me more about what kind of expertise do you need to develop such a system? As in the most important knowledge one most have to be able to work on such a thing

Thanks, buddy! I'm having fun. There are a few sides to it. There are the actual physical surgical tools that you have to design, test, and manufacture. Then there's the robot that adjusts those tools. That stuff is a lot of CAD and 3D printing. The camera is a big deal and it's a ton of work to get that right. Then of course you have all the software, which is a slew of computer vision models that operate on a local computer in a careful dance of resource orchestration. The software has a lot: UI, grpc services, ml models on containers, inverse kinematics for calculating robot position, hardware interfaces, etc. Then there's a bunch of regulatory, validation, compliance, etc.

To answer your question about expertise, it really depends on what you are interested in. We have some dedicated mechanical engineers with medical device experience. The software is handled by a few computer vision and full stack folks. So there's different skillsets.

I'm a bit of a journeyman and as a result, I am decent across all of it. I always did software and went where the wind blew. It's been 20-something years since I graduated so I've seen a lot. About 10 years ago I got a job I was totally unqualified for, which was R&D for a company that made lab equipment for testing gas and oil. I was solo and had to learn all the mechatronics stuff - CAD, microcontrollers, electronics, etc. Check out this video: https://youtu.be/MA6hnyXx4p4. That specific experience allows me to be the glue in our engineering org.

To work here, you don't need medical experience. We have plenty of that. One of the cool things about engineering, especially software engineering, is that you can float around between verticals. I've learned all about media, finance, petroleum, insurance, waste disposal, etc. The skills translate. If you are purely software, I recommend picking up an Arduino and some motors and building something like a simple pan/tilt mechanism with an accompanying mobile app. Just do it. It might inspire you. I think curiosity and enthusiasm are the most valuable traits one can have.
