Robots With Knives!

We humans love to scare ourselves with what we can accomplish. Horror movies, roller coasters, even robo-coasters, we enjoy creating something for the explicit purpose of making us nervous and scared.

Whenever we make a demonstration with our industrial robots that demonstrates lightning-fast speed, someone always wants to push it to the next level. For instance, some coworkers recently programmed the Adept Quattro robot to play the iPhone game “1 to 50” in the lab. This required a finger on the robot that would trigger the capacitive touch screen, and a suitable finger was found (from someone’s leftover Halloween collection).

Once we started sharing the video, we started getting comparison to the infamous “Knife trick” performed by Bishop in the movie Aliens, and people asking if we could put a knife on the robot and do it as fast as in the movie. For example, this guy, but faster.

New Applications For Industrial Robots (virtual conference)

Back in May, I wrote about the first Robotics Virtual Conference held by online robotics media firm RoboticsTrends. The idea is simple – instead of travelling to attend a physical trade show, you can attend online via a web-based interface. The result is not so simple. Vendors struggle to figure out how to present information on their physical robot product in a virtual world, which results in just a mess of file downloads. I think I downloaded 40 or so files (pdfs, whitepapers, and videos) from the exhibitors, but only found the time and energy to go through a dozen or so. The “booths” are attended by one or more employees, almost like a chat room, so you can get some actual conversation in. So you’re talking one-on-one with someone (who’s probably talking to other people at the same time). At a real show, a lot of people tend to mill around and listen in on other conversations, either they don’t know what to ask or don’t want to intrude on a potential sale. So the experience is pretty different. For a first-time event though, I have to cut them some slack. There were very few technical issues, hopefully they’ll have them cleaned up.

Adept acquires MobileRobots, an insider’s perspective

Adept Technology, a leading provider of industrial robotics and automation (and my employer), announced on Monday that they would be acquiring MobileRobots Inc, a provider of industry leading autonomous robot and automated guided vehicle (AGV) technologies. I’ve been at Adept for about 10 years, and have been involved in some pretty cool technologies over the years. . However, nothing quite compares to the excitement of this venture into mobile robotics.

Robot waiters, bartenders

From Singularity Hub:

Ok, so I’ve seen Motoman‘s Dexter Bot before, most notably as the RoboBar:

[youtube=http://www.youtube.com/watch?v=fnnblb5HbYs]

And i think it’s really cool. It shows a very different concept of human-robot interaction and collaboration. The thing that’s most unique about this, in my opinion, is that it’s an industrial arm that’s been built to do more humanoid things, as opposed to a lot of the  mechanisms out there, which seem to come from the hobby field. Mechanisms coming from such different backgrounds, while both considered “robots”, have very different characteristics, good and bad.

The industrial robots are going to be structurally much more solid, because the manufacturers have had a decade or two to fine-tune them for their markets. These are typically assembly/factory lines, and (especially for articulated arms) welding and painting. These require a very stiff mechanism, the engineers have tuned the resonant frequencies to reduce jitter and improve settling time, they can pack the most efficient motors and gearboxes into them, balance the weight of the links against the power required to move them and the resulting performance. They are marvels of engineering, but tend to be rather expensive ($40-$60k for a reasonably small robot arm), and are often ugly and clunky-looking

(as an example, the SV-3 from Motoman, the precursor to the HP3 used in DexterBot)

Motoman SV-3

On the other hand, mechanisms that come from the hobby industry tend to be significantly cheaper, sexier looking, and have more of a friendly appearance to them.

But the DexterBot is starting to bridge that gap. It comes from an industrial arm (the HP3), but doesn’t have any use in an industrial environment. It’s almost completely useless to the current factory market – it’s way too slow to be a suitable replacement for human workers, it’s way too expensive to be competitive with automation solutions. Likewise, it has almost no value in the non-industrial market for the same reasons – too slow and expensive to compete with a minimum-wage cook, for sure.

So what’s the point?

It’s a step. A money-loser but a market-grower. It opens the eyes of the industrial robot manufacturers to the concept of human-robot collaboration, shared workspace, and consumer uses for industrial products. Just like Honda’s Asimo robot wasn’t cost-effective, it did its share of climbing obstacles (figuratively and literally) to open our eyes to real walking robots. Don’t expect to see DexterBot serving you drinks at your local dive bar, but expect more of the industrial robots to be used in consumer-friendly spaces.

National Robotics Week

National Robotics Week 2010 has come and gone, but left some cool robotics tech in its wake.

Wednesday’s Robot Block Party at Stanford was a blast, got to see some really cool displays from Willow Garage, Intuitive Surgical, Adept Technology, the Stanford Stickybot and DARPA Urban Challenge vehicle

Robot Block Party:

Then on Friday Adept had an Open House with lots of demos to show:

Here, the visitor draws graffiti onto an Apple iPad using GraffitiAnalysis. The tags are uploaded to a server, then downloaded by the robot controller and repeated in realtime:

And more demos (other videos may come later).

I may come back later and add more detail about some of the tech, but that’s a brief recap! Some pictures can be found on the flickr page, some videos on YouTube, look for the tags roboweek and roboweek2010!
