In a similar position as yourself, I'm in deep tech and can share similar frustrations where funding is scarce and commercialization seems far away. Having attempted to fundraise, I can say that we've been blessed to be forced to bootstrap at this stage and are slowly identifying our commercial path. Happy to help you find a market.
The good news is that you are in a hot investment area and I can probably point you in the right direction with the right investors. Firstly, how far along are you? Do you have a prototype and have you spoken to potential customers?
One program that might be suitable for you is Creative Destruction Lab, who specialize in deep tech such as robotics (https://www.creativedestructionlab.com/program/). They don't take any equity and you'd have opportunities to be mentored and invested. I'd be happy to provide an introduction.
