A new delta robot packaging system from Cama Group creates an end-of-line packaging machine with multiple robots operating from a single controller, reducing the overall size and cost of the system.
Chuck, While packaging automation is a big market for this type of capability, integration of robotic arms into machines is a phenomena that reaches into all types of applications. Especially with the development of technology to create "programmable safety zones", it's now possible for robotics to become more tightly integrated with the machine process. That reduces floor space requirements and enables automation engineers to design around robotic arms to eliminate some custom design. Now with the ability to program the line controls for the machine, plus robotic motions, using the same programming environment on a single machine controller, it's creating more incentive to move machine designs in this direction.
TJ, The most common and popular software approach for these type of systems is based on the IEC61131-3 programming languages, with solutions provided by a wide range of automation vendors. These automation software packages are already wide in used for general machine control, so robotic kinematics is another group of software objects/libraries that can be integrated into the package.
naperlou, for vision I'd agree with you. I've not seen a PAC that tightly integrated vision the way motion has been.
Eventually, it will be; I can see the benefits of merging the two for even better robotics. I haven't seen any of the big automation companies offer a camera yet.
Centralized control does make sense (assuming redundancy is covered properly) when there are numerous devices with similar control requirements. Central control means a single point to adjust programming, and a central point from which supervisory and HMI systems can collect data.
Distributed controls means touching each and every machine to roll out a change (connect, download, verify, disconnect, again and again). It also means a much more complex task for collecting data. In some cases, the number of connections becomes a limiting factor.
ttemple, we use a lot of Rockwell Automation hardware and software (Logix5000).
I've also used AML from Pacific Scientific (a long time ago). Both are an integrated programming environment, and I find I like that, a LOT.
Having to have different suites of software for different parts of a large system can get cumbersome, FAST, especially when the software does not play nice with other packages (Rockwell and Siemens are notorious for this).
Running different suites in their own Virtual Machines is how we handle that problem, but again, it's much nicer to have a single programming environment.
Frankly, I agree with TJ. This becomes a single point of failure. I also am more inclined, in design projects I am involved in, to push the intellgence out to where it is used. There are lots of processors that have specilaized instructions that will handle the computational load at a much lower power level. Vision systems, for example, are tending toward smart cameras. This allows most, of not all, of the processing to be done at the camera, thereby reducing the traffic on the communications link.
The main issue that seems to be addressed here is the comminications latency. There are standard busses that handle this with predictability and high speed.
My company makes control systems using a central PAC for motion control describe in the article. Having a single point of programming makes system development simple and saves time.
However, that central PAC becomes a source of single-point failure unless suitable redundancy is built into the PAC hardware.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
