> Two robotic hands that can work in co-ordination just as human hands do. Extremely difficult to solve, but money is there.

You will find the most automated Mc Donalds in the world in Switzerland. Mc Donalds over there has a lot more automation there than it does in the US, both in the cooking and in the order taking.

Either this is because the automation is extremely difficult to do, but is simpler in Switzerland. Or alternatively, this is because in most countries in the world humans are cheaper than the automated system, even after it has already been developed.

As someone who does research on robotics for a living. The problem is not the former, but the latter.
