robotics/5116_2e518938aacdf0fd_16.txt | Nonetheless, the consistent pattern of forces across varying duct diameters and motor regimes enables the formulation of qualitative guidelines for the best drone stability. In a circular air duct, optimal stability is achieved by flying at a height of about 10 cm, for all the studied diameters. This positioning places... |
robotics/1211_fe650460e2acb790_447.txt | Transitory obstacles - random, short-lived and unpredictable objects - are difficult to capture in any traditional mapping system, yet they have significant negative impacts on the accessibility of mobility- and visually-impaired individuals. These transitory obstacles include sidewalk obstructions, construction detour... |

robotics/a5ab3215_8742.txt | Below follow some basic facts about the role of the collection of all rotation matrices of a fixed dimension (here mostly 3) in mathematics and particularly in physics where rotational symmetry is a requirement of every truly fundamental law (due to the assumption of isotropy of space ), and where the same symmetry, wh... |

robotics/b4fd1e3a_6704.txt | In the motivation, we argued that not all prompts are equally informative: trivial ones provide little learning signal, while challenging prompts better reveal differences across candidate solutions. A shortcoming of the original GRPO algorithm is that it treats all prompts uniformly, ignoring this variability. The con... |
robotics/854_aeed479c586722c5_416.txt | Quel mess. I installed the Cessna regulator -- this involved quite a lot of new wiring -- and then proceeded to damage it by stupidly attaching a ground lead to what I believed was a ground post, but was really A+. Melted some perfectly good wire. I thought I had damaged the alternator too, so I took it off -- a hideou... |
robotics/1202_d14a34391eb82ba2_87.txt | Overall, these cans exhibit two very different approaches to music reproduction; the Nighthawk is perfect for losing yourself and floating off into beautiful music, and the Cascade is for those times when you want your tunes to suck you in, grab you by the throat and drag you round the room until you agree to start gri... |
robotics/854_aeed479c586722c5_93.txt | A kindly reader expressed concern about my long silence. Actually, I am well and so is the airplane. (The nation, maybe not so much.) I have done very little work on the plane lately, for several reasons. One is simply that I am in a period of slackened interest in working on it; my interest in various projects -- impr... |
robotics/1266_e26caa74eb27f4da_232.txt | Machine learning models are highly vulnerable to label flipping, i.e., the adversarial modification (poisoning) of training labels to compromise performance. Thus, deriving robustness certificates is important to guarantee that test predictions remain unaffected and to understand worst-case robustness behavior. However... |
robotics/33f2ff25_7784.txt | Hello. The servo is not made for continuous rotation, and it rotating continuously is a sign that you are asking it to go beyond its limit, which could cause it to be destroyed. The standard 1-2 ms range should get you close to the full turn, and you can gradually expand the range while keeping it centered at 1.5 ms to... |
robotics/8204_74e707900ee88d80_1.txt | It is important to note that when multiple solutions exist, neither IK approach specifies which solution is "best." Also, it is important to note that many of the solutions produced by IK techniques may be infeasible for a robot to undertake. For example, IK solutions may exceed joint limits, cause the robot to self-co... |

robotics/21338_ffcd46c10cd05485_294.txt | Disturbances decrease vehicle stability and increase driver's mental and physical workload. Especially unexpected disturbances such as lateral winds have severe effect on vehicle stability and driver's workload. This study aims at building a driver model of steering operations in lateral wind toward developing effectiv... |
