robotics/0713280d_6739.txt | Llama 3.3_70B Instruct Model for Natural Reasoning The dataset was further refined by using the Llama 3.3_70b_instruct model to answer natural reasoning prompts. Only the prompts for which Llama could not provide an answer were kept for further evaluation. This step ensured that the dataset included questions that requ... |
robotics/8895_80ceca0747858829_122.txt | Understanding typical brain development and its relationship to cognitive abilities is crucial for developmental neurosciences. Here, I applied normative modeling to a large dataset of adolescent brain imaging (N > 10,000, age 9-15 years) to characterize developmental trajectories of brain structure, function, and whit... |
robotics/7864_a4310d6eb1fb3d24_89.txt | We tend to think that a motor speed of 20,000 RPM or more is pretty fast, but it's only 333.3 revs per second, so a single slot encoder will have an output frequency of 333.3Hz. In electronics, this is slow, and it's easy to process signals up to 10kHz with even very ordinary parts. This would allow speeds of 600,000... |

robotics/21338_ffcd46c10cd05485_223.txt | 1. Experiments carried out on anaesthetized cats showed that increasing blood flow, through the lobes of a lung, by 133% (S.E. 33%) generated an average of 0.75 impulses/sec (S.E. 0.3) in ten almost silent J receptors. Equivalent activity was produced by injecting 12-18 micrograms phenyl diguanide/kg into the right atr... |
robotics/21338_ffcd46c10cd05485_106.txt | We report a simple model of two drive-response-type coupled chaotic oscillators, where the response system copies the nonlinearity of the driver system. It leads to a coherent motion of the trajectories of the coupled systems that establishes a constant separating distance in time between the driver and the response at... |
robotics/854_bfbc7fe81559e716_437.txt | On the matter of choosing which material to replace the ninjaflex gears with, we had 3 options to chose from. The first was a red silicon oven-mitt with rectangular ridges, a green silicon oven-mitt with hexagonal ridges, and an ice-cube tray with cubical ridges. To determine which material would work best, we put them... |
robotics/1fa757fd_9922.txt | P - Higher makes Quad more sharp (oscillates if too high or low)I - High Makes the quad more digital mechanical (measures errors) holds the attitude better if raisedD - High values dampen the P (works against P, flattens the curve) D-term relates on the gyro measurements |
robotics/854_bfbc7fe81559e716_84.txt | Next Saturday, Iron Reign will be participating in the DISD STEM Expo for our second year. As we did last year, we are bringing our Mobile Learning Experience to the Kay Bailey Hutchison Convention Center and will serve children in our community to spark an interest in STEM fields and learning. Dallas City of Learning,... |

robotics/854_aeed479c586722c5_309.txt | My oil temperature indication -- not the temperature itself, obviously -- began fluctuating rapidly on the flight down from Paso. I cleaned up a bunch of connections, but when I flew to test the vacuum pump -- it appears normal -- the oil temp was still jumping around. I then decided the problem was an apparent short i... |
robotics/1211_fe650460e2acb790_237.txt | An adaptive training procedure is developed for a network of electronic neurons, which controls a mobile robot driving around in an unknown environment while avoiding obstacles. The neuronal network controls the angular velocity of the wheels of the robot based on the sensor readings. The nodes in the neuronal network ... |
robotics/854_bfbc7fe81559e716_210.txt | We reached out to the Dallas Personal Robotics Group to present - we've presented to them in the past about gyros - this was actually our biggest numerical outreach of the season back in the day. This year, we wanted to present again on computer vision, as this is something that they were very interested in, but we als... |
