Science Daily February 18, 2022 There are numerous challenges in the deployment of wearable devices with soft sensing technologies due to their poor resilience, high energy consumption, and omnidirectional strain responsivity. Researchers in the UK have developed a versatile ionic gelatin-glycerol hydrogel for soft sensing applications. The device is inexpensive and easy to manufacture, self-healable at room temperature, can undergo strains of up to 454%, presents stability over long periods of time, and is biocompatible and biodegradable. The material is ideal for strain sensing applications, with a linear correlation coefficient R2 = 0.9971 and a pressure-insensitive conduction mechanism. The experimental results show […]

Integrating microchips for electronic skin
Science Daily January 22, 2020 To closely replicate natural skin, it is necessary to interconnect a large number of individual sensors. An international team of researchers (Japan, Germany) developed a sensor system that consists of a 2 x 4 array of magnetic sensors, an organic bootstrap shift register, required for controlling the sensor matrix, and organic signal amplifiers. All electronic components are based on organic thin-film transistors and are integrated within a single platform. The researchers demonstrated that the system has a high magnetic sensitivity and can acquire the two-dimensional magnetic field distribution in real time and very robust against […]
Robots to autocomplete Soldier tasks
Science Daily April 4, 2019 The Army envisions a future battlefield wrought with teams of Soldiers and autonomous systems. As part of this future vision, the Army is looking to create technologies that can predict states and behaviors of the individual to create a more optimized team. A team of researchers in the US (ARL, Columbia University, SUNY Buffalo, University of Pennsylvania, Carnegie Mellon University, UC Santa Barbara) is looking at ways the dynamics and architecture of the human brain may be coordinated to predict such behaviors and consequently optimize team performance. While this research focuses on a single person, […]
Engineers create a robot that can ‘imagine’ itself
Science Daily January 30, 2019 Researchers at Columbia University have created a robot that learns what it is, from scratch, with zero prior knowledge of physics, geometry, or motor dynamics. After a brief period of “babbling,” and within about a day of intensive computing, the robot creates a self-simulation and uses that self-simulator internally to contemplate and adapt to different situations, handling new tasks as well as detecting and repairing damage in its own body. Using a four-degree-of-freedom articulated robotic arm, initially the robot moved randomly and collected approximately one thousand trajectories. Then used deep learning to create a self-model. […]
An insect-inspired drone deforms upon impact
Science Daily July 26, 2018 An international team of researchers (Switzerland, Japan) has developed an origami structure which consists of a prestretched elastomeric membrane, akin to the soft resilin joints of insect wings, sandwiched between rigid tiles, akin to the rigid cuticles of insect wings. The dual-stiffness properties of the structure are validated by using the origami as an element of a quadcopter frame that can withstand aerodynamic forces within its flight envelope but softens during collisions to avoid permanent damage… read more.

Robot designed to defend factories against cyberthreats
Phys.org April 3, 2018 Researchers at Georgia Institute of Technology developed HoneyBot designed to lure in digital troublemakers and trick the bad actors into giving up valuable information to cybersecurity professionals. The gadget can be monitored and controlled through the internet. But unlike other remote-controlled robots, the HoneyBot’s special ability is tricking its operators into thinking it is performing one task, when it is doing something completely different. Rather than allowing the hacker to then run amok in the physical world, the robot could be designed to follow certain commands deemed harmless but stopping short of doing anything dangerous…read more.
Smart Swarms Seek New Ways to Cooperate
Quanta Magazine February 14, 2018 Researchers at the Georgia Institute of Technology are experimenting with flapping robots called “smarticles” which can’t move on their own. But when a lot of these objects are put together they start to work as a unit. Researchers are learning how to control these systems so that when the swarm comes together, its members can carry out complex behaviors without any centralized direction. Other efforts in the field of self-organizing robots include “droplet-size robots” being developed at the University of Colorado, “Kilobot swarms” at Harvard University, and “swarmanoids” out of a pioneering lab in Belgium… […]
Researchers help robots think and plan in the abstract
Eurekalert February 8, 2018 A team of researchers in the US (Brown University, MIT) there has been less progress in perceptual abstraction, which has to do with helping a robot make sense of its pixelated surroundings. They gave a robot called Ana a set of high-level motor skills for manipulating the objects in a room. Once Ana was armed with her learned abstract representation, the researchers asked her to do something that required some planning which Ana executed. According to the researchers, their research provides an important theoretical building block for applying artificial intelligence to robotics… read more. Video Open […]
