robotics/fa62afdc_6486.txt | To address the aforementioned issues, researchers have proposed a hybrid navigation strategy that combines YOLOv7 with Rapidly-exploring Random Trees (RRTs), known as NAV-YOLO-RRT. This approach enables real-time tracking of dynamic targets and adaptive path reconstruction, significantly improving obstacle-avoidance su... |

robotics/21338_ffcd46c10cd05485_378.txt | Traditional methodologies for identifying and recruiting controls in epidemiologic case-control studies, such as random digit dialing or neighborhood walk, suffer from declining response rates. Here, we revisit the feasibility and comparability of using alternative sources of controls, specifically friend and family co... |
robotics/10702_d51cfa8e319db209_92.txt | Real particles are things you can hold, kick, absorb and study. Virtual particles cannot be isolated and studied — only more general effects of these general disturbances can be studied. What the author leaves out is that those general effects ARE measured and studied, and in fact are hugely important — Casimir effect,... |

robotics/854_aeed479c586722c5_484.txt | Got back from Oshkosh this morning after a 3.7-hour flight from Santa Fe, where I had stopped for the night. The return took 10.3 hours in all, 1.1 more than the trip eastward; part of the excess was due to less favorable winds and part to the longer southern routing and some deviating around cells while leaving OSH an... |
robotics/417fe265_8835.txt | We live in a flat Euclidean space, and we also love to represent the curves in this space. What if we can embed the curves in a higher dimensional Euclidean flat space? Would not that be amazing? We will get rid of the singularities, right? |

robotics/1211_fe650460e2acb790_359.txt | The growing interest for self-driving cars provides a demand for scene understanding and obstacle detection algorithms. One of the most challenging problems in this field is the problem of pedestrian detection. Main difficulties arise from a diverse appearances of pedestrians. Poor conditions such as fog and low light... |
