robotics/854_aeed479c586722c5_740.txt | It's very warm at altitude these days; at 15,000 DA I was getting 170 ktas at 8 gph, but I started getting misses if I climbed much higher. This was a problem on Melmoth 1 until I switched to pressurized Slick mags. The Slick is an inferior mag to the Bendix, or so I'm told, but it does have this one advantage. People ... |
robotics/10312_c73789492ecb27ec_50.txt | At the core of many AAL technologies lie machine learning approaches [122 Privacy-Aware Monitoring for Assisted Living. Springer, Cham (2025)")] (Chap. 2 in this volume), and progress in this domain will improve accuracy and reliability of the AAL core components, leading to trustworthy applications in areas like fall ... |
robotics/d8eba64b_6700.txt | Dense signals anchored to verifiable correctness. As argued in the motivation, binary verifiers alone provide stable but overly coarse supervision, while reward models offer nuanced distinctions that are easily corrupted if left unconstrained. However, we find that a naive combination of rule-based verification and rew... |

Figure 2.36 presents a general classi... |
robotics/7140db43_6693.txt | Group Relative Policy Optimization. GRPO (Shao et al., 2024) extends RLVR by optimizing over multiple responses per prompt rather than treating them independently. Instead of relying on a single trajectory, GRPO compares groups of candidate solutions and assigns relative advantages, which stabilizes learning and improv... |
robotics/854_aeed479c586722c5_579.txt | I should clarify something about the flow separation I noted a couple of days ago. I did not make sufficiently explicit that the picture showing reversed flow over a portion of the wing root was taken at 85 kias, which is the flaps-up approach speed. Now, this kind of separation at approach speed has no operational sig... |
robotics/e1af5b5c_6856.txt | Since resetting the agent has an associated time cost in the real world, we also penalize the agent when it fails to reach the goal state within the time limit (e.g., K𝐾-K- italic_K where K𝐾Kitalic_K timesteps is required to reset the agent). The episodic returns and lengths are adjusted appropriately. For example, ... |
robotics/8e760fdc_8437.txt | In Euclidean geometry , a rotation is an example of an isometry , a transformation that moves points without changing the distances between them. Rotations are distinguished from other isometries by two additional properties: they leave (at least) one point fixed, and they leave handedness unchanged. In contrast, a... |
robotics/adb82c34_6994.txt | Where is BLDC motor used? Brushless DC motors are used in varied appliances such as ACs, washing machines, consumer electronics, etc. How long do Brushless DC motors and Brushed motors last? On an average, the lifetime of a brushed motor is about 1000 to 3000 hours whereas, of a brushless motor is 10000 hours. Are brus... |
robotics/14178_d4eee9ddd5e6add2_265.txt | rangefinding, which provides reflectance information in addition to range information. Choosing a map representation for a particular mobile robot requires, first, understanding the sensors available on the mobile robot, and, second, understanding the mobile robot’s functional requirements (e.g., required goal precisio... |
robotics/5116_532aad47262e4780_49.txt | Hi Abishek, I’m not sure I totally understand the question, but If I’m understanding you correctly, you want to use MPU6050 measured tilt angles to make a cursor move on the computer screen. The code here (or the DMP code in ) will provide tilt angle coordinates from the MPU6050. To translate those into screen coordina... |
robotics/51862ed4_0486.txt | I redesigned the robot. The hardware has not changed, but the software has been redesigned. In the old version there was a separate PID controller for each motor. To steer the robot to the right or left, the setpoint of the PID controller was assigned by the appropriate value. If the robot should drive straight ahead a... |
robotics/2cc457bd_6513.txt | The ROS 2 control framework consists of several key components that work together to provide real-time robot control. The Controller Manager (CM) connects the controllers and hardware abstraction sides of the ROS2_control framework. It also serves as the entry point for users via ROS services. |
robotics/2885_33c4da2a7541fc56_151.txt | ROM: A Computer’s Personality Intel would call the ROM the “personality” of the system, as it is the part that tells the CPU how to behave. To change how a computer behaved, you simply had to re-program the ROM. Traditionally, you’d have to undergo laborious rewiring of the individual transistors or change out large ci... |
