robotics/854_aeed479c586722c5_232.txt | I swapped the #1 and #3 EGT wires -- but not the probes this time -- back to where they started from. Now it's the #1 indication that's dead; so the problem is the thermocouple. And I tried out the new inches of water gauge, which turned out to be a huge disappointment; it's completely inaccurate, indicating anywhere f... |
robotics/f43b282e_8802.txt | The task space is a space in which the robot s task can be naturally expressed. The decision of how to define the task space is driven by the task, independently of the robot. |
robotics/c9895395_7099.txt | The boundaries of the translation component η t (taking the x dimension as an example) and the rotation component η r (taking the α dimension as an example) are defined separately. The attraction of the target point to the robot is represented by the negative gradient of the gravitational potential field function, whic... |
robotics/1266_e26caa74eb27f4da_98.txt | With hundreds of thousands of language models available on Huggingface today, efficiently evaluating and utilizing these models across various downstream tasks has become increasingly critical. Many existing methods repeatedly learn task-specific representations of Large Language Models (LLMs), which leads to inefficie... |
robotics/854_aeed479c586722c5_485.txt | Despite its annoying habit of dispensing a fine mist over the windscreen, the engine used only about one quart of oil per 15 hours. The trip was glitch-free, except for the nuisance of not being able to shut off the back seat ventilator from the front. I finally realized that a simple solution to that problem would be ... |
robotics/3e232421_10555.txt | The basic Kalman filter is limited to a linear assumption. More complex systems, however, can be nonlinear. The nonlinearity can be associated either with the process model or with the observation model or with both. |

robotics/854_aeed479c586722c5_773.txt | Having returned from vacation, I flew for 40 minutes or so yesterday to exercise the airplane and to further investigate the effect, if any, of the flap track fairings. At 10,500 feet, where the density altitude was a bit over 13,000, at 2,400/27 with the mixture about 60 deg. F. lean of peak, I got 166 ktas on 8.1 gph... |
robotics/21338_ffcd46c10cd05485_244.txt | As part of the research supported by U.S. Department of Energy (DOE) Advanced Hydropower Turbine System (AHTS) Program, the Pacific Northwest National Laboratory (PNNL) conducted a study where age-0 and age-1 chinook salmon, as well as several other types of fish, were released into a submerged water jet to quantify in... |
robotics/8895_80ceca0747858829_252.txt | The degradation mechanisms and charge carrier dynamics in single- and multi-layer perovskite photovoltaics under ultrafast pulsed laser ablation are explored through a comprehensive suite of experimental and computational methods. A custom laser ablation setup, varied in terms of thermal and spatial precision, is utili... |
robotics/dc008857_7104.txt | In conclusion, this paper successfully presented a comprehensive approach addressing the challenge of computing the optimal solution for inverse kinematics in redundant robots. By employing the D-H parameter method, we effectively derived eight distinct sets of vector solutions, significantly enhancing the solution spa... |
robotics/9a9f5fb7_7964.txt | For odd dimensions n 2k 1, a proper rotation R will have an odd number of eigenvalues, with at least one λ 1 and the axis of rotation will be an odd dimensional subspace. Proof: |
robotics/854_aeed479c586722c5_223.txt | While I was away I visited Randy Greene, an old friend who is CEO of Safe Flight Corporation; they make all sorts of equipment ranging from leading edge stall warnings to autothrottles and other such fancy stuff. We flew the company's 172, which is a testbed for their new angle of attack system. This is a completely re... |
robotics/067c1d1e_0205.txt | This paper presents a terrestrial localization system based on 5G infrastructure as a viable alternative to GNSS, particularly in scenarios where GNSS signals are obstructed or unavailable. It discusses network planning aimed at enabling positioning as a primary service, in contrast to the traditional focus on communic... |
robotics/5479da96_7788.txt | So I wanted to understand what the motivation for continuous turn servos are? Why not just buy a properly geared motor rather than hacking a motor? From the way you described, you are removing the potentiometer from the control loop and therfore its simply a open-loop control. I'd be surprised if there weren't cheap op... |
