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.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
