Thanks for the info and video, Jim E. I was quite improssed at PackExpo by the safety features of the robots. You could put your hand in the path of the robot and it would stop instantly. Now gearing down, jut an instant stop. Most robot producers are touting higher levels of safety.
As a robot programmer with my previous company, I got to learn a bit about robotics. (Well, I still fool with them here, but only in maintenance aspects usually.)
The ABB FlexPicker is really amazing. Watching the youtube video of it picking up widgets off of a conveyor and putting them onto another conveyor in an endless cycle at amazingly high speed is really mesmerizing to watch.
The end tooling / gripper is usually one of the limiting factors in robotics use. Some items just don't pick up well with robots. One of the most incredible grippers to see is a "Jamming Phase Transition" gripper. It's basically a balloon filled with coffee grounds, and the balloon can have a vacuum applied. The gripper is placed against an item and a vacuum applied, which makes the device rigid, which conforms to what it was pressed against. You really have to see this to believe it, and here's a video: https://www.youtube.com/watch?v=ZKOI_lVDPpw
I haven't seen any industrial applications of this technology yet, but I hope it will eventually happen.
As for the human-safe robots, the Baxter seems more like a toy without the ability to reach pre-programmed points with accuracy. The Universal Robotics devices seem more like industrial robots. I played with a UR-5 at a trade-show and was impressed with it. I tested it running into my arm and it was a bizarre to me considering that I'm used to working with giant robots which would crush me. The reach and payload capacity of their two models aren't good enough for any of my applications yet, but I'd love to get one in my plant somehow.
MyDesign, I think robots really help in reducing the power of labor to determine everything in where stuff is built. If logistics costs play a bigger role than labor, it's natural that manufacturing moves closer to markets. A side benefit would be energy savings and environmental gains.
Good point, Mydesign. It does look like companies are putting more emphasis on packing. And while the robots reduce the need for manual labor, they do employ engineers. They also reduce the differential between labor costs in Asia and the rest of the world. Thus, logistics costs may trump labor as the expense to watch -- that helps fuel the trend toward buiulding plants close to markets.
My Design, safety was one of the selling points at Pack Expo. The servo drives and safety programs tied to individual robots seem to be an advancement in safety. The virtual light curtains and instant halt seem to be taking safety to a new level.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
Design News and Digi-Key presents: Creating & Testing Your First RTOS Application Using MQX, a crash course that will look at defining a project, selecting a target processor, blocking code, defining tasks, completing code, and debugging.
These are the toys that inspired budding engineers to try out sublime designs, create miniature structures, and experiment with bizarre contraptions using sets that could be torn down and reconstructed over and over.
PowerStream is deploying the microgrid at its headquarters to demonstrate how people can generate and distribute their own energy and make their homes and businesses more sustainable through renewables.
