Matthew Humphries for PCMag: Catching a fish can be tough, even if you are just trying to net a goldfish in a small tank. That's because the fish spots the danger and makes a swim for it. But what if you didn't need a net because you're controlling an invisible grabbing robot? That's what Xuanhe Zhao, a professor of mechanical engineering at MIT succeeded in creating, but its applications go way beyond catching and releasing fish unharmed. The robot is constructed of a transparent hydrogel, which is strong and durable but mostly made of water. As the video below explains, each arm of the robot is constructed from 3D-printed hollow cubes of hydrogel, which are then linked together. By injecting water using a syringe it's possible to make the arms curl and uncurl quickly in a grabbing motion. Cont'd...
Raspberry Pi serves as the main controller board for the setup, capturing the images using the Pi Camera, controlling the Line LASER diode and providing control signals to the EasyDriver (Stepper Motor Driver).
The services that fabb.one will provide through their fabbs range from printing, injection molding, CNC milling to scanning, conceptual and CAD design.
Tekla S. Perry for IEEE Spectrum: Velo3D, based in Santa Clara, Calif., has $22.1 million in venture investment to do something in 3-D printing: That makes it fourth among 2015’s best-funded stealth-mode tech companies in the United States, according to CB Insights. This dollar number is about all the hard news that has come out of this startup, founded in 2014 by Benyamin Butler and Erel Milshtein. But job postings, talks at conferences, and other breadcrumbs left along Velo3D's development trail—has created a sketchy outline of this company’s plans. Consider which 3-D printing technology is ready for disruption: metal. 3-D printing of plastics took off after 2009, when a key patent that covered the deposition technology expired; we now have desktop printers for 3-D plastic objects as cheap as $350. Printing of metal objects—done regularly in industry, particularly aerospace—uses a different, and, to date, far more expensive technology: selective laser sintering. This technology melts metal powders into solid shapes; it requires high temperatures, and far more complicated equipment than what’s found in the layering sort of printers used for plastic. The patent for this technology expired in early 2014—just before the formation of Velo3D. At the time, industry experts indicated that there wouldn’t be cheap metal printers coming anytime soon, but rather, would only come after “a significant breakthrough on the materials side,” OpenSLS’s Andreas Bastian told GigaOm in 2014. Could Velo3D’s founders have that breakthrough figured out? Cont'd...
3DR Holdings, LLC and Rising Media, Inc. to Host Singapore's Premier 3D Printing and Robotics Event; January 26-27, 2016 at Suntec Singapore Convention & Exhibition Centre
3DR Holdings LLC and Rising Media, Inc. announced that they have purchased MecklerMedia's Inside 3D Printing and RoboUniverse international events as equal partners and will continue to run all upcoming events as scheduled.
Plastics Technology announces agenda for 26th annual event on injection molding includes presentations on injection molding, automation, 3D printing, materials and process maintenance
NinjaTek, a division of Fenner Drives and makers of the popular line of NinjaFlex and SemiFlex 3D printing filaments, today announced the upcoming launch of two new 3D printing materials in the first quarter of 2016.
MarkForged, Inc - a company focused on industrial strength 3D printing for businesses - is announcing today a strong finish to 2015, with 400% growth in revenue year over year.
My research involves developing techniques to 3D print electric motors and electronics. This goes beyond the usual 3D printed structures - structures don't do anything. To do things, we need motors and electronics to control those motors.
The first-of-its-kind solution consists of a standard commercially available robot, composite deposition end-effector hardware and a comprehensive software suite.
By being able to design diffusers in 3D and print them, we streamline the prototyping process tremendously. We can do virtual simulations with the 3D models to get a sense of the effectiveness, and we can make aesthetic or functional changes before it's printed.
FABTECH 2015 will be held from November 9th - 12th in Chicago, Illinois. This RoboticsTomorrow.com Special Tradeshow report aims to bring you news, articles and products from this years event.
The 3D Printshow is the first dedicated 3D printing event anywhere in the world.
BY HANNAH ROSE MENDOZA for 3DPrint.com: Soft robotics is a relatively new field of research that aims to create flexible robots that are more easily adaptable to human interaction. Often, the forms of these creations and the mechanics of their movement are inspired by a close study of nature in an effort to ‘go organic’ with machines. 3D printing with flexible filament is one way in which this integration of robot and movement is taking on a flexible aspect. For this particular installation, titled Exo-biote, the National Institute for Research in Computer and Control and the Department of Science and Visual Culture at the Imaginarium worked together, with support from Neuflize Bank, to create a robot organism that embodied the formal typologies and demonstrated the possibilities for movements in soft robots. After all, some of nature’s most amazing machines have nearly entirely soft bodies – think of the octopus, for example, able to lift, carry, walk, swim, shape change, camouflage itself, and fit through a tube no bigger than a quarter!

Mechatronic Motion Solutions from Festo is a unique system of components, modules, and software. It integrates all types of pneumatic, servopneumatic and (electro)mechanical automation motion and combines them according to your task. Irrespective of the control system environment you use, Mechatronic Motion Solutions always provides the appropriate interfaces. The fingers can be actively moved and their strength amplified; the operator's hand movements are registered and transmitted to the robotic hand in real time. The objectives are to enhance the strength and endurance of the human hand, to extend humans' scope of action and to secure them an independent lifestyle even at an advanced age.
