New technique improves AI ability to map 3D space with 2D cameras
Researchers have developed a technique that allows artificial intelligence (AI) programs to better map three-dimensional spaces using two-dimensional images captured by multiple cameras. Because the technique works effectively with limited computational resources, it holds promise for improving the navigation of autonomous vehicles. “Most autonomous vehicles use powerful AI programs called vision transformers to take 2D…

Robot radiotherapy could improve treatments for eye disease
Researchers from King’s, with doctors at King’s College Hospital NHS Foundation Trust, have successfully used a new robot system to improve treatment for debilitating eye disease. The custom-built robot was used to treat wet neovascular age-related macular degeneration (AMD), administering a one-off, minimally invasive dose of radiation, followed by patients’ routine treatment with injections into…

Towards a new era in flexible piezoelectric sensors for both humans and robots
Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, researchers from Japan tackled these issues by developing a novel piezoelectric composite material made from electrospun polyvinylidene fluoride nanofibers combined with dopamine. Sensors made from…

3D-printed mini-actuators can move small soft robots, lock them into new shapes
Researchers from North Carolina State University have demonstrated miniature soft hydraulic actuators that can be used to control the deformation and motion of soft robots that are less than a millimeter thick. The researchers have also demonstrated that this technique works with shape memory materials, allowing users to repeatedly lock the soft robots into a…

Making climate models relevant for local decision-makers
Climate models are a key technology in predicting the impacts of climate change. By running simulations of the Earthโs climate, scientists and policymakers can estimate conditions like sea level rise, flooding, and rising temperatures, and make decisions about how to appropriately respond. But current climate models struggle to provide this information quickly or affordably enough…

New algorithm discovers language just by watching videos
Mark Hamilton, an MIT PhD student in electrical engineering and computer science and affiliate of MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), wants to use machines to understand how animals communicate. To do that, he set out first to create a system that can learn human language โfrom scratch.โ โFunny enough, the key moment…
