I'm guessing at numbers from my limited experience, but a new robot development (let's say with some sophisticated features either hardware or software--not both) is probably a 20-50 person development. Salary (in normal land, not crazy west coast land) for a 2.5 year development is 6-15 million. Material cost runs 10-40% more.

So expect something like 4-10 new robot platforms coming out as a result of this. In a market where there's not a plethora of vendors, that's respectable.

If anyone has more direct experience I'd be happy to be corrected.

Is robotics currently limited mostly by money, i.e. with enough investment we could accelerate the robotic future significantly ? or is it mostly the need for new, better ideas?

I think most companies don't expect to burn cash in needless ways that most startups are expected. It's very possible to take what many consider a sizable investment and use it to continue development of an actual product. Where as most startups take money like this, make spaghetti, throw it at the wall and see what sticks.
