robotics/854_aeed479c586722c5_869.txt | When I landed at Whiteman on December 23 the tower controller asked me to cycle my transponder; "I'm negative transponder," I replied, forgetting that I was thereby confessing to an infraction, Whiteman being within 30 nm of a Class B airport. The controller was apparently in a tolerant mood, because he didn't complain... |
robotics/1afa944a_7297.txt | A set of n candidates solutions q random is computed for each robot initial configuration defined at point 2, using the weight matrices generated at point 3 to weight the pseudoinverse. The joint velocity profiles of each solution are obtained through Equation (9). Each candidate solution q random is then obtai... |
robotics/854_bfbc7fe81559e716_22.txt | We tested out a few different materials:* Silicone Baking Mats - The mats were a very neutral option because they didn't have any huge advantages or disadvantages (other than not adhering well). These could have been used, however, there were other better options. * Shelf Liner - It was far too slippery. Also, when thi... |
robotics/bd0ebc74_9628.txt | Facial recognition-based anti-spoofing devices: ToF cameras in augmented face recognition systems prevent unauthorized access through face recognition spoofing by analyzing in-depth data that can differentiate between a real face and an attempt to replicate it (e.g., a mask or photo). |
robotics/5b607fb9_8508.txt | A basic 3D rotation (also called elemental rotation) is a rotation about one of the axes of a coordinate system. The following three basic rotation matrices rotate vectors by an angle θ about the x-, y-, or z-axis, in three dimensions, using the right-hand rule which codifies their alternating signs. Notice that the ri... |
robotics/14178_d4eee9ddd5e6add2_304.txt | During the prediction and measurement updates only mean t and covariance t are updated. Therefore, the Kalman filter is based on four equations: two for updating t and t in the prediction update, and another two in the measurement update. In Kalman filtering the measurement update is also commonly called correc... |
robotics/8888e40d_0144.txt | The brushless DC (BLDC) motor has found favor in applications as diverse as computer cooling fans, disk drives, cordless power tools, electric bicycles, and record turntables. As prices continue to fall, the motors will find even wider use in all but the most price-sensitive applications. However, as demand increases, ... |
robotics/854_aeed479c586722c5_629.txt | Not surprisingly, we left later on Wednesday than we had planned. We stopped for the night at Gallup instead of somewhere in Kansas, flew to eastern Indiana the next day, and arrived at Orange County (Montgomery, NY) at noon on Friday. Block performance did not match the spot numbers observed during local flights. In t... |
robotics/1266_e26caa74eb27f4da_234.txt | Text-to-image generation models can create high-quality images from input prompts. However, they struggle to support the consistent generation of identity-preserving requirements for storytelling. Existing approaches to this problem typically require extensive training in large datasets or additional modifications to t... |

robotics/1211_fe650460e2acb790_179.txt | On-chip LiDAR sensors for vehicle collision avoidance are a rapidly expanding area of research and development. The assessment of reliable obstacle detection using data collected by LiDAR sensors has become a key issue that the scientific community is actively exploring. The design of a self-tuning methodology and its ... |
