robotics/854_aeed479c586722c5_156.txt | I decided that the place to start was to continuity between the thermocouple and the rotary switch. So I opened the cowling and disconnected the thermocouple. At this point I went off the rails. Thinking that a thermocouple is a bimetallic junction and therefore ought to have a low resistance, I ed the thermocouple wit... |

robotics/6f9c3c07_7935.txt | The two-dimensional case is the only non-trivial case where the rotation matrices group is commutative; it does not matter in which order rotations are multiply performed. For the 3-dimensional case, for example, a different order of multiple rotations gives a different result. (E.g., rotating a cell phone along z-axis... |

robotics/8dc05a7b_6707.txt | Training datasets. A central question is whether reasoning skills acquired through RLVR on verifiable data can generalize to tasks whose correctness cannot be mechanically checked. To empirically examine this, we construct three distinct training datasets based on subsets of the OpenMathReasoning (Moshkov et al., 2025)... |
robotics/7864_a4310d6eb1fb3d24_25.txt | The functions for BLDC motors are generally provided by a fairly comprehensive micro-processor, such as those made by ATMEL (e.g. ATMega or similar) which seem to have the lion's , but other microcontrollers can be used as well. Controllers designed for brushed DC motors are (usually) far less complex, but some of tho... |
robotics/4f6d1e7a_6427.txt | In densely populated environments, such as hospitals and shopping centres, robots with basic obstacle-avoidance capabilities often exhibit rigid behaviour that may cause discomfort or even conflict with pedestrians. As a result, Socially Aware Navigation (SAN) is emerging as a key research focus within ROS-based naviga... |
robotics/1266_e26caa74eb27f4da_356.txt | This work tackles an intriguing and fundamental open challenge in representation learning: Given a well-trained deep learning model, can it be reprogrammed to enhance its robustness against adversarial or noisy input perturbations without altering its parameters?To explore this, we revisit the core feature transformati... |

robotics/854_aeed479c586722c5_247.txt | At this point the reversal of the intake manifold has become sufficiently remote that my impressions are perhaps more objective than they were in the excitement of initial testing. My sense now is that nothing was gained in either cooling effectiveness or speed (yesterday it was 162 ktas at 7.7 gph -- about normal) whe... |

robotics/06b82ab5_7814.txt | Dave 16 Oct 2013 I am trying to put together a flight simulator for my senior design project. I need a motor that puts out about 800 ft lbs of torque and I want to use a servo motor with a gearbox to increase the torque. Should I find a continuous servo motor and use any gearbox with the correct gear ratio or do I need... |
robotics/66432e22_0757.txt | “Beware: Dirty Electricity from Clean Energy”: There are some issues that we all need to be aware of regarding “clean energy” and some dire health ramifications from things such as smart meters, solar inverters, wind turbine frequencies, and CFLs. A device’s impact on human health should be a primary consideration in d... |
