Robotics is a wide field with many opportunities:
- Computer Vision - mechanical hardware - path planning and localization, SLAM - Control engineering - Software engineering - ...
Then, there are plenty of more business oriented roles: - Application engineering => how can robots solve the customers problem - technical sales / marketing - ...
I think it makes the most sense to leverage your previous experience to move into the field and than find out how to continue. E.g. Start as an application engineer and then move towards control. Or if your background is ML/AI, Computer vision and then progress into another field.
> Actually kind of surprised that there are still so few robotic jobs and companies. Guess it is harder then I think...
Robotics takes a lot of people and money. Hardware, Software, an actual problem to be solved, ... I think once we are seeing a platform(s) to build robots more easily, there will be more companies as well.
