Robodelivery and high-end, low-usage equipment rental (and NPR interview)
Earlier on, I identified robot delivery vehicles as one of the steps on the roadmap to robot cars. In fact, these are officially what the DARPA grand challenges really seek, since the military wants robots that can move things through danger zones without putting soldiers at risk.
Deliverbots may well be allowed on the road before fully automated robotaxis for humans because there are fewer safety issues. Deliverbots can go more slowly, as most cargo is not super-urgent. If they go slower, and have a low weight limit, it may be the case that they can't cause much harm if they go astray. Obviously if a deliverbot crashes into an inanimate object, it just cost money and doesn't injure people. The deliverbot might be programmed to be extra-cautious and slow around anything like a person. As such, it might be allowed on the road sooner.
I gave a talk on Robot cars at the BIL conference, and an attendee came up to suggest the deliverbots enable a new type of equipment rental. Because they can bring you rental equipment quickly, cheaply and with no hassle, they make renting vastly more efficient and convenient. People will end up renting things they would never consider renting today. Nowadays you only rent things you really need which are too expensive or bulky to own.
By the way, the new NPR morning show the "Bryant Park Project" decided to interview a pair of speakers, one from TED and one from BIL, so I talked about my robot cars talk. You can listen to the segment or follow links to hear the whole show.
It was suggested even something as simple as a vacuum cleaner could become a rental item. Instead of buying a $200 vacuum to clean your floors once a week, you might well rent a super-high quality $2,000 unit which comes to you with short notice via deliverbot. This would also be how you might treat all sorts of specialized, bulky or expensive tools. Few will keep their own lathe, band saw or laser engraver, but if you can get one in 10 minutes, you would never need to.
(Here in silicon valley, an outfit called Tech Shop offers a shop filled with all the tools and toys builders like, for a membership fee and materials cost. It's great for those who are close to it or want to trek there, but this could be better. This in turn would also let us make better use of the space in our homes, not storing things we don't really need to have.
