Foellmer demonstrated what happens when you stick your arm into the path of Baxter's pick-and-place operation -- it stops right away. It also won't pinch you if you get your arm or leg stuck inside its area of operation, such as under one of its moving arms. At first I let Foellmer risk his limbs, not mine. Then I let Baxter's arms run into my arm. The robot's force-detecting motors stopped it immediately.
Being also a materials person, I immediately noticed that Baxter has mostly plastic surfaces, not hard, metallic ones. That's highly uncommon in industrial machines, although not unusual in some service robots. It's also another thing that makes this robot safer.
The second major goal was to make Baxter simple enough so human workers can train it to do easy but repetitive tasks. In other words, it can be programmed by people on the floor, not those with advanced engineering degrees wearing a special software pendant. The fact that it doesn't need complex programming also means it's simple to integrate into existing automated operations, although many smaller manufacturers don't have existing automated assembly lines anyway. Most of their assembly cells are inhabited by humans doing things by hand. But the simplicity of programming makes changing Baxter's tasks much easier than is usually the case in industrial robots. We've discussed that excruciating complexity on several Design News comment boards.

Baxter does not move large parts: It's got a payload limit of five pounds per arm. It's also got a small footprint, weighs about the same as an average-sized adult man, and can be moved around fairly easily. It's clearly not meant to do everything, and doesn't do the kind of high-speed pick-and-place on display in Anaheim by major industrial robot makers like ABB. The other revolutionary thing about Baxter is its open-source Unix-based OS, ROS (robot operating system). That plus an SDK to be released later this year will help open up the robot as a platform for development.
Baxter's $22,000 price tag is much lower than the typical two-armed industrial robot, which should make it more appealing to small companies that want to start using automation. It's already been beta tested at a couple of customer sites, Foellmer said, and has just started shipping.
Didn't realize that 3D printing for medical applications are over 30 percent and trending upward. It makes sense because 3D printing is a great fit for creating individualized, custom parts out of titanitum at a reasonable cost and with a rapid turn-around time.
My husband just told me he showed this article to one of the guys at work, who said the bone rasp looks like a diamond studded borer used in industrial mining. I've been avoiding thinking about what this femur borer actually does, but--Ouch!
Glad you enjoyed my report, Nadine. Actually there's been a lot of intelligent robot design here in the US, but much of it's been aimed at military or rescue robots. Some's also been done in industrial robots, but not with the specific goal of a robot like Baxter. I'm really interested to see what developers do with the SDK.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
