An Italian team has built a prototype robot they call Dustbot which is aimed (in a backwards way) at the deliverbot vision.
The goal of the dustbot is to travel on demand to houses through the narrow, pedestrian streets of European cities so people can give the robot their trash, which it then takes back to the dump and drops there. It does not automate the pickup of the trash — you have to be there and put your bag into it, though it is able to drop it on it own. It is not clear if they plan to have it operate on streets with cars, or if it is truly ready to wander with civilians.
This is an evolutionary extension of the already common delivery robots used in factory floors and in hospitals. The hospital robots interact with the general public, and do it simply by being so slow that impact or injury is very unlikely, even with a programming error. But looking at the market of the very narrow, mostly or all-pedestrian ancient urban street, the challenge is more difficult than a hospital, but not as difficult as a vehicle that has to go fast enough that it could hurt somebody.
In tune with my predictions about deliverbots, the key is that the robot does not have to be in a hurry, so it can go as slow as is necessary to be safe. As the system improves, that speed gets faster and faster until it’s practical to go on urban streets at 15mph (ducking out of the way of cars) and eventually at the same speed as the cars. This robot can also be limited to a specific area in which it is well tested and armed with accurate data, because that’s much less of a restriction on delivery robots than it is on cars. (If you need to deliver elsewhere, use another service — but people will resist a taxi that will only take them certain places.)
Dustbot is probably too slow right now to be economical, particularly because you must wait for it. A robot that can pick up a standardized container is not too hard, however. One nice advantage of working on the trash problem is that there is no issue in leaving it on the street, so you don’t need to arrange home access for deliveries as a deliverbot would. There’s also little risk of piracy of the cargo, or damaging it.
There’s lots of video and photos on the site, here is a fluffy BBC video about the Dustbot. Note that this is about a year old — I just had not heard of it until recently.

Yesterday we had a meeting using some videoconferencing. In a situation I find fairly common, the setup was a meeting room with many people, and then a small number of people calling in remotely. In spite of this being a fairly common situation, I have had trouble finding conferencing systems that do this particular task very well. I have not been looking in the high-priced end but I believe the more modestly priced tools should be able to focus on this and make it work. Yesterday we used Oovoo, one of the few multi-part conference systems to support PC and Mac, with some good but many bad results.
The common answer, namely a speakerphone on the meeting room table and a conference bridge system, is pretty unsatisfactory, though the technology is stable enough that it is easy to get going. The remote people are never really part of the meeting. It’s harder for them to engage in random banter, and the call fidelity is usually low and never better than PSTN phone quality. They usually have trouble hearing some of the people in the meeting room, though fancier systems with remote microphones help a bit with that.
The audio level
The next step up is a higher quality audio call. For this Skype is an excellent and free solution. The additional audio quality offers a closer sense of being in the room, and better hearing in both directions. It comes with a downside in that tools like Skype often pick up ambient noise in the room (mostly with remote callers) including clacking of keyboards, random background noises and bleeps and bloops of software using the speakers of the computer. While Skype has very good echo cancellation for those who wish to use it in speakerphone mode, I still strongly recommend the use of headsets by those calling in remotely, and even the judicious use of muting. There’s a lot more Skype and others could do in this department, but a headset is a real winner, and they are cheap.
Most of these notes also apply to video calling which of course includes audio. read more »

Here’s an idea that seems a bit wild and scary at first, but it’s doable today and has broad benefits: Small aircraft that don’t have landing gear, but instead land and take off from robotic “can’t miss” platforms pulled by cables on short airfields.
UPDATE: Some updated ideas and a link to a funded research project looking at similar ideas.
For every small aircraft purchaser, a big decision is whether to get retractable landing gear. They are very expensive, and create a risk of failure, but your plane will fly a lot faster and be more fuel efficient if you get them. What if we could leave the landing gear on the ground?
Imagine a wheeled platform on the runway with robotic control and a variety of systems to perfectly track an approaching aircraft. Pulled by cables, it can accelerate at several “g”s forward and back and left and right. As the aircraft approaches it tracks it and the cockpit display indicates positive lock. If the plane veers left, it veers left. If the plane speeds up it speeds up. Pretty much no matter what the pilot or winds do (other than missing the runway entirely) the plane can’t miss landing on it. It’s spring loaded so even if the landing is a bit hard the shock is cushioned. Done right, it’s just like having fancy shock absorbing landing gear. read more »

This story from the Register about a test at the Stanford VAIL Lab reports an interesting result. They created a fake robocar, with a human driver hidden in the back. The test subjects then were told they could push the autopilot button and use the car. And they did, immediately picking up their newspapers to read as they would in a taxi (which is what they really were in.)
Not only that, when they were told the robot could not figure out the situation and needed human assist, they gave it, and then went right back to autopilot.
So trust of a robocar is already at a higher level than we might expect. I’ve ridden in Junior, and K. has stood in front of it, but that was with a human ready to take over the controls. Like many others pondering the future of robotic transportation, I believe we’ll only put robocars on our ordinary streets once they demonstrate a level of safety much superior to human drivers what I call the “robocar vision.” This does not mean a perfect level of safety, though, and the resulting accidents and occasional fatalities will be the cause of much debate and legal wrangling which will slow the development of the technology when it is saving lives.

Just back from some time on the road, which always prompts me to think of ways to improve travel.
First, and most simply: Every hotel room comes with a small foldable stand on which to put your suitcase. The problem is they all come with exactly one of these. In some rooms there is space on the tables or dresser for another bag, but often there is not. Doing solo business travel I have just one bag, but all couples, and many solo wanderers have more than one, and so you end up putting bags on the floor. It’s quite annoying, since these stands can hardly be very expensive — folding cloth and metal chairs can be had for $10 in most stores. I’ve only tried once or twice to ask housekeeping for another, and been surprised to learn they don’t keep spares. Frankly, I think it would be cheaper to just put 2 in every room than waste staff time delivering extras, but either would work. And the hotel often knows if a room is booked for 2 rather than one in advance. If you have a bellman take up your bags, not only does the bellman see how many bags you have but it’s a sure thing you have several. Every bell station should have some extra racks and throw what is needed on the luggage cart.
Next, I think it would be interesting to see car rental companies develop cars just for road trips. They are the largest buyers of cars (and often owned by car companies) so custom cars are not out of the question. SUVs and some minivans contain many of the features of a road trip car, but they are often 3 times as expensive when reserved in advance, and 1.5x to 2x more expensive in gasoline usage. What features might a road trip car have? read more »
