robotics/75_7390704801cbf8ee_33.txt | Figure 2 show two schematics of the light bulb circuit above. In both, the important parts to note are the functional components, namely the lamp and the switch, and the power and ground terminals. In the diagram on the right, the whole circuit is shown as a loop, with the battery (marked V1) to the left of the loop. I... |
robotics/854_aeed479c586722c5_384.txt | We came back last Tuesday from two weeks on the east coast. On Thursday I did a circuit of the pattern to test the theory that retracting the flaps during the roll-out would reduce the tendency for one main gear strut or the other to remain excessively extended. The experiment was inconclusive; the weather was quite wa... |

robotics/fc8634db_6723.txt | We evaluated variance-aware reweighting based on reward-model score variance, which emphasizes ambiguous, high-variance prompts while down-weighting trivial ones to reduce overfitting with the setting of training with easy-to-verify samples based on Qwen-4B-Base. This dynamic adjustment yields consistent gains, particu... |
robotics/1211_fe650460e2acb790_17.txt | A method of automated detection of negative obstacles (potholes, ditches, and the like) ahead of ground vehicles at night involves processing of imagery from thermal-infrared cameras aimed at the terrain ahead of the vehicles. The method is being developed as part of an overall obstacle-avoidance scheme for autonomous ... |

robotics/854_66c38b16a0fafc7d_2.txt | For the specific case of the (mostly older) flat head screws, fabricating a driver with an aluminum blade is recommended to prevent damage to the screw slots. These screws also tend to have long thin slots, which don't fit the typical screwdriver well at all. The special tool can be as simple as an aluminum roofing nai... |

robotics/854_aeed479c586722c5_814.txt | One of the chronic problems associated with updraft cooling has been rough running while taxiing for any length of time on hot days or after landing, when the heat rising from the engine would boil the fuel in the lines. Having been designed with downdraft cooling in mind, the engine has its throttle body, distributor ... |
robotics/1211_fe650460e2acb790_108.txt | Autonomous robots often rely on models of their sensing and actions for intelligent decision making. However, when operating in unconstrained environments, the complexity of the world makes it infeasible to create models that are accurate in every situation. This article addresses the problem of using potentially large... |
robotics/854_bfbc7fe81559e716_69.txt | At the Oklahoma qualifier, we saw numerous teams with similar systems to that of ours. However, since we had the mobilized gripper arms to stack with auto alignment, we were able to collect glyphs easier. In spite of that, after observing other teams in action, we realized our current gripper method had the issue of no... |
