An aerial robot that can independently control its own position and orientation
Unmanned aerial vehicles (UAVs), commonly known as drones, are now used to capture images and carry out a wide range of missions in outdoor environments. While there are now several UAV designs with different advantages and characteristics, most conventional aerial...
Generating and detecting graphene plasmon polaritons with terahertz electronics
Graphene plasmon polaritons are a class of hybrid quasi-particles with advantageous optoelectronic properties. These particles have proved promising for the development of miniaturized nanoscale circuits that operate in the terahertz and mid-infrared regions of the...
An adaptive method to detumble non-rigid satellites using robots
More than 8,000 man-made satellites orbit planet Earth today, many of which were launched into space decades ago. Repairing and maintaining the proper operation of these satellites is not always easy and often requires carefully planned and targeted interventions.
A droplet-sensing bionic e-skin that could further enhance robotic perception
In recent years, many research teams have been trying to design artificial skins with electronic properties for humanoid robots, smart prosthetics and other bio-inspired systems. These skins could sense the textures and tactile properties of objects, allowing various...
A flapping microrobot inspired by the wing dynamics of rhinoceros beetles
The wing dynamics of flying animal species have been the inspiration for numerous flying robotic systems. While birds and bats typically flap their wings using the force produced by their pectoral and wing muscles, the processes underlying the wing movements of many...
A bio-inspired vision sensor that can detect spectrally distinctive features
The ability to detect objects in settings with unfavorable lighting, for example at night, in shadowed locations or in foggy conditions, could greatly improve the reliability of autonomous vehicles and mobile robotic systems. Most widely employed computer vision...
Why editing the knowledge of LLMs post-training can create messy ripple effects
After the advent of ChatGPT, the readily available model developed by Open AI, large language models (LLMs) have become increasingly widespread, with many online users now accessing them daily to quickly get answers to their queries, source information or produce...
A visual-linguistic framework that enables open-vocabulary object grasping in robots
To be deployed in a broad range of real-world dynamic settings, robots should be able to successfully complete various manual tasks, ranging from household chores to complex manufacturing or agricultural processes. These manual tasks entail grasping, manipulating and...
A strategy to synthesize fin-like metal nanosheets for 2D transistors
The effective integration of extremely thin insulating layers with two-dimensional (2D) semiconductors could enable the fabrication of 2D transistors with an electrical capacitance comparable to SiO2 with thicknesses below 1-nm. These transistors could, in turn,...
