Grasping and transporting objects is one of the most critical tasks for robots in a variety of fields. This task requires accurate 3D measurement of the objects. However, transparent or specular objects make measurement challenging, reducing grasping success rate. To address this, researchers have developed HEAPGrasp, a new technique that performs 3D measurement of objects using only their silhouettes, thus avoiding dependence on their optical properties. This approach significantly improves grasping success rate of robots.
Dentists are exposed to intense lighting for long hours, but its long-term impact on eye health is often overlooked. This study evaluates whether chronic exposure to dental lighting, especially blue and white LEDs, can damage the retina and disrupt its normal function. By combining human data with advanced imaging and animal models, the research uncovers hidden occupational risks and highlights the need for safer lighting practices to help protect dentists’ vision.
Virtual reality feels more “real” when users can touch a physical prop, but most haptic proxies follow a one-object-one-model approach that is costly and hard to deploy. A new fabric topological haptic proxy (FTHP) integrates origami-inspired constraints and embedded sensing fibers so a single cloth can switch among flat, folded and transforming states for different interactions. A lightweight neural network decodes the signals and achieves about 92.4% action recognition accuracy.
A global meta-analysis led by Dr Zareena Khan and Professor Gemma Harvey from Queen Mary University of London analysed data from 64 studies covering 61 species of wild animals across freshwater and terrestrial environments.
The researchers found that animal activity altered geomorphic processes by an average of 136 percent in freshwater ecosystems and 66 percent in terrestrial environments.
