robotics/92141a23_7004.txt | One popular solution to this problem, implemented in ROHM Semiconductor's BD62011FS fan motor controller, is to start the motor in a trapezoidal control mode and switch to sinusoidal control once it reaches a given speed (typically 5 - 100 Hz), when the interpolation is likely to be more accurate. |
robotics/854_bfbc7fe81559e716_436.txt | The finger gripper is the pinnacle of technological evolution, with class, durability and most importantly, metal. But it does lack one defining feature - grip. Currently, the underside of the metal plate on the gripper has parts from our ninjaflex gears used in Relic Recovery, and while it has all the refinement of an... |
robotics/1ce2932d_7577.txt | Computational ComplexityThe computations involved in producing state estimate x k occur in the blocks following Optical Flow Sensor (OFS) and IMU blocks. OFS and IMU perform internal computations to produce their outputs and therefore do not impose any additional computational demands in the realization of the filter... |

robotics/854_aeed479c586722c5_766.txt | I flew to Santa Maria today to visit Paul Lipps, an exponent, like me, of the "piece of shit" school of craftsmanship. Nevertheless, he cares about neatness where it counts. When I was getting ready to leave he cast a disapproving eye on my wings, which have not been washed since before Oshkosh 2004. He wetted a towel ... |
robotics/04184c07_7799.txt | Hi, David. We don't know of any specific considerations with digital servos, but I think it's going to depend on the particular model of servo, and we haven't tried modifying that one. You should get a pretty good idea of whether it will be practical as soon as you open it up. - Kevin (engineer at Pololu) This comment ... |
robotics/0a40cd31_0623.txt | VTOL tiltrotor vehicles can tilt their motors to transition between hover and forward flight. This section defines the properties of the tilting servos. These are mapped to specific motors in the motor geometry for a tiltrotor. The example below shows the tilt servo setup for the tiltrotor motor geometry shown above. T... |
robotics/e603abd7_9895.txt | Do a punch out and see if there is any fast oscillations, if so, increase TPA. Good TPA will give you a relatively smooth punch out. I personally wouldn't use TPA higher than 0.4, otherwise your quad might feel loose at high throttle. |
robotics/7235_0a41a01ffb589adc_11.txt | Quadrotor helicopters are emerging as a popular platform for unmanned aerial vehicle (UAV) research, due to the simplicity of their construction and maintenance, their ability to hover, and their vertical take off and landing (VTOL) capability. Current designs have often considered only nominal operating conditions for... |

robotics/0707e30f_0706.txt | This research examines the SBS/RS used in the logistics hub of a leader distributor company in the tire industry. This sector is suitable with respect to the identified RQs since, as explained further in Sect. 4.1, tires may arrive at the sorting area in a unordered sequence, thus affecting outbound loading efficiency.... |
robotics/c7f1ca0e_0110.txt | The rapid advancement of large language models (LLMs) has paved the way for the development of highly capable autonomous agents. However, existing multi-agent frameworks often struggle with integrating diverse capable third-party agents due to reliance on agents defined within their own ecosystems. They also face chall... |

robotics/e967d0dd_6622.txt | Consequently, the proposed SMFH showed promising feasibilities. Among them, the primary contribution of this study is to present a simplified structure that embeds a single motor, and it is anticipated to consume less satellite power. Moreover, in light of our findings on the interpolated relation of the input versus t... |

robotics/854_66c38b16a0fafc7d_7.txt | Note: One would think that when shooting with a DSLR in "live view" mode (which uses the sensor with the mirror up) it would behave like a point-and-shoot and be silent if the simulated shutter sound is turned off. But this is usually not the case for technical reasons having to do with the way the sensor reads out dat... |
