robotics/854_aeed479c586722c5_16.txt | After some floundering around I learned that you can buy the plastic breakable link for a Rapco vacuum pump. It came today. The chief mechanic at Able Air told me that once one of these things has failed you might as well get a new pump, because it's friction in the pump that caused it to fail. However, I can't discern... |
robotics/854_aeed479c586722c5_774.txt | One of the irritations of the generally wonderful Internet is the amount of outdated information on it. I'm not innocent. The website of the software company in which I'm a partner, AeroLogic, is extremely cobwebby. Just keeping a commercial website up to date is a full time job. My ranting about this is due to my havi... |

From now on we plan to set up boxes to bring for the week before.* Practice Our presentation was better this time. Still, we didn't get enough practice. There were a few long pauses between people and we... |
robotics/8895_80ceca0747858829_112.txt | Whole grains are increasingly recommended as healthier alternatives to refined grains due to their higher fiber content, better nutrient profile, and purported benefits for blood sugar management. However, many people struggle with properly preparing whole grains, potentially leading to reduced nutritional benefits. A ... |
robotics/1266_e26caa74eb27f4da_188.txt | Message passing graph neural networks (GNNs) are known to have limited expressive power in their ability to distinguish some non-isomorphic graphs.Because of this, it is well known that they are unable to detect or count arbitrary graph substructures (i.e., solving the subgraph isomorphism problem), a task that is of g... |

robotics/1211_fe650460e2acb790_78.txt | This paper presents a seamlessly controlled human multi-robot system comprised of ground and aerial robots of semiautonomous nature for source localization tasks. The system combines augmented reality interfaces capabilities with human supervisor's ability to control multiple robots. The role of this human multi-robot ... |
robotics/24c6033a_6973.txt | Commutation follows a six-step sequence, where only two of the three phases conduct current at any time. The ESC reads the rotor position either directly and switches the transistor into the inverter circuit accordingly. |
robotics/11105904_7229.txt | When solving a multi-objective optimization problem, it is usually desired to find a solution that is as close as possible to the Pareto optimal set. In the ideal case, the full Pareto optimal set can be exactly computed, and it is possible to choose the preferred solution among its members. Exhaustive computation of t... |
robotics/21338_ffcd46c10cd05485_258.txt | The fuzzy controllers studied in this paper are the ones that employ N trapezoidal-shaped members for input fuzzy sets, Zadeh fuzzy logic and a centroid defuzzification algorithm for output fuzzy set. The author analytically proves that the structure of the fuzzy controllers is the sum of a global nonlinear controller ... |
robotics/854_aeed479c586722c5_97.txt | I collected some temperature readings in the duct leading into the oil cooler, with and without the deflector. The temperatures were, on average, 20 degrees F above ambient with the deflector and 30 above without. This suggests that maybe I ought to look into making up some sort of duct that runs directly from the peri... |

The diamond cutter would be used to machine mirror surface finished three-meter wide optical components, with accuracy measured ... |
robotics/854_aeed479c586722c5_480.txt | Last week I began wiring the nav lights. My usual scheme is to use a single shielded wire for a circuit, carrying the return through the shield, and I had accordingly run two wires to the light cove, one for the nav light and one for the halogen flasher. But Paul Lipps, who designed the flasher circuit, informed me tha... |
