Will Tesla’s Electric Semis Take Over?

Elon Musk’s latest product unveiling, held last week in Hawthorne, California, was done in the accepted fashion of introducing a new product these days, which is for the CEO to stand alone on a stage, backed by giant screens and, if possible, a piece of the subject hardware too.  Musk claimed that the new electric truck he plans to start building in a year or so will travel 500 miles on a single charge.  Critics cited in the New York…

Touch-sensitive avatar-robotic arm based on real-time haptics

Touch sensitive avatar-robotic arm based on real-time haptics developed by Takahiro Nozaki and colleagues at the Keio University Haptics Research Center. Credit: Keio University Researchers at Keio University’s Haptics Research Center have developed a ‘real-time-avatar-robotic arm’ that transmits sound, vision, and highly sensitive feelings of touch to remotely located users. This innovative touch sensitive robotic technology was reported in the October 2017 issue of IEEE Transactions on Industrial Electronics and demonstrated at CEATEC (October 2017, Tokyo). The technology is expected…

Integrated technologies to recover metal and plastic from electronic waste

VTT Technical Research Centre of Finland has developed a new electronic waste recycling concept that combines a range of technologies and reduces waste. One of the technologies included in the concept is gasification, which is used to recover not only metals and rare-earth elements from the waste but also organic components that can be used to produce energy or products, such as plastic and chemicals. VTT has brought together a group of Finnish partners to promote material-efficient production. Vast amounts…

Flexible ‘skin’ can help robots, prosthetics perform everyday tasks by sensing shear force

The flexible sensor skin wrapped around the robot finger (orange) is the first to measure shear forces with similar sensitivity as a human hand — which is critical for successfully gripping and manipulating objects. Credit: UCLA If a robot is sent to disable a roadside bomb—or delicately handle an egg while cooking you an omelet—it needs to be able to sense when objects are slipping out of its grasp. Yet to date it’s been difficult or impossible for most robotic…

Detailed look at 2-D structure of turbulence in tokamaks — ScienceDaily

A key hurdle for fusion researchers is understanding turbulence, the ripples and eddies that can cause the superhot plasma that fuels fusion reactions to leak heat and particles and keep fusion from taking place. Comprehending and reducing turbulence will facilitate the development of fusion as a safe, clean and abundant source of energy for generating electricity from power plants around the world. At the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), scientists have assembled a large database…

Using maths to map mines deep underground

The researchers translated the complex design used in microchips to create an efficient tunnel network. Credit: Shutterstock The wires of a tiny microchip may seem a world away from a huge underground mine full of complex tunnels, but for a team of University of Melbourne researchers, the design principles are very similar. More than 20 years ago, Professor Doreen Thomas and Professor Hyam Rubinstein were working on innovative methods of network optimisation – which aims to ensure optimal usage for…

Ceramic pump moves molten metal at a record 1,400 degrees Celsius

Liquid metal flowing at 1400 degrees Celsius in the laboratory of Asegun Henry at Georgia Tech. Even though all the surrounding materials are glowing, the tin remains reflective and the ripples from the pool of tin below are visible via reflections from the stream. Credit: Caleb Amy, Georgia Tech A ceramic-based mechanical pump able to operate at record temperatures of more than 1,400 degrees Celsius (1,673 Kelvin) can transfer high temperature liquids such as molten tin, enabling a new generation…

Flexible sensors can detect movement in GI tract

A new flexible piezoelectric sensor is 2 by 2.5 centimeters and can be rolled up and swallowed. “For the first time, we showed that a flexible, piezoelectric device can stay in the stomach up to two days without any electrical or mechanical degradation,” assistant professor Canan Dagdeviren, left, says. Dagdeviren is next to researcher Giovanni Traverso. Credit: Massachusetts Institute of Technology Researchers at MIT and Brigham and Women’s Hospital have built a flexible sensor that can be rolled up and…

Innovative contribution to the energy transition — ScienceDaily

In the cooperative EPSYLON research project funded by the German Federal Ministry of Education and Research, scientists from Johannes Gutenberg University Mainz (JGU) and Evonik Performance Materials GmbH have succeeded in developing a state-of-the-art and innovative electro-organic synthesis. The results of their research, presented in last week’s issue of Science Advances, allow the use of electrosynthesis as a trend-setting and sustainable green chemistry for technical applications. The method developed allows the operator to react flexibly to the available supply of…

Engineering a Million-Mile Journey with Uber ATG

Poornima Kaniarasu is a data platform engineer with Uber’s Advanced Technologies Group (ATG). In this article, she shares how her background in robotics led her to Uber Engineering, where she works on the technologies powering Uber’s self-driving vehicles. “Are you sure this is the place?” My Uber driver asked as he pulled up to my destination. I was pretty sure I inputted in the right address to my Uber app, but this definitely did not look like a corporate building.…
