Gathering more effective human demonstrations to teach robots new skills
To effectively assist humans in real-world settings, robots should be able to learn new skills and adapt their actions based on what users require them to do at different times. One way to achieve this would be to design computational approaches that allow robots to...
Silicon heterojunction solar cells with 26.4% efficiencies fabricated using scalable deposition techniques
Solar technologies are helping to reduce carbon emissions and are set to continue contributing to the mitigation of climate change. One type of solar technology found to be promising for future photovoltaic applications is silicon heterojunction (SHJ) solar cells.
An approach to realize Potts annealing using single-photon avalanche diodes
Massively parallel annealing processors, where the computing nodes on a single processor can simultaneously perform a series of coordinated operations, could have a huge potential for tackling complex sampling and optimization problems. Electronics engineers and...
Study shows that large language models can strategically deceive users when under pressure
Artificial intelligence (AI) tools are now widely employed worldwide, assisting both engineers and non-expert users with a wide range of tasks. Assessing the safety and reliability of these tools is thus of utmost importance, as it could ultimately help to better...
A new model that allows robots to re-identify and follow human users
In recent years, roboticists and computer scientists have introduced various new computational tools that could improve interactions between robots and humans in real-world settings. The overreaching goal of these tools is to make robots more responsive and attuned to...
Using hierarchical generative models to enhance the motor control of autonomous robots
To best move in their surrounding environment and tackle everyday tasks, robots should be able to perform complex motions, effectively coordinating the movement of individual limbs. Roboticists and computer scientists have thus been trying to develop computational...
Reconfigurable molybdenum ditelluride devices with multiple functions
Over the past decades, electronics engineers have been trying to develop increasingly smaller and highly performing field effect transistors (FETs) with multiple functions. FETs are crucial components of most electronics on the market today, which can control the...
An approach that allows robots to learn in changing environments from human feedback and exploration
To best assist humans in real-world settings, robots should be able to continuously acquire useful new skills in dynamic and rapidly changing environments. Currently, however, most robots can only tackle tasks that they have been previously trained on and can only...
A sensing paw that could improve the ability of legged robots to move on different terrains
Legged robots that artificially replicate the body structure and movements of animals could efficiently complete missions in a wide range of environments, including various outdoor natural settings. To do so, however, these robots should be able to walk on different...
