I am happy to see this kind of progress being made.

How long will it be until we can have robo-nannies, robot companions for elderly who can shop, assist them, take their aging owners to appointments, clean the house, fix a meal and serve it, and do the dishes afterwards? I think that the day will come and it may be within the next 20 years or sooner. Sadly I'm sure DARPA will use the same tech to replace human soldiers on the battlefield and these wonders of technology will be used first to kill and only late to care for and nurture humanity where it needs care and nurturing the most.

And of course these will cost upwards of $100k at first. But the costs will come down and production will go up and soon we'll get used to robots in the grocery store or acting as a driver or a care giver for an elderly patient. But the costs will soon be proven to be well worth it when it's obvious you're getting a servant, companion, nurse, and personal assistant all rolled into one. Remember it doesn't need to eat, sleep, etc.
