With each successive generation of smart phones, their built-in cameras improve dramatically and provide remarkably good picture quality and features often not available in expensive gear. Due to... |

robotics/854_bfbc7fe81559e716_293.txt | Since our project manager is leaving for college next year, there has been an effort to teach the younger students on our team to take on this role and its many responsibilities. These responsibilities include updating the Gantt chart, writing meeting logs, gathering information for meeting logs when you are not able t... |
robotics/d9e1b3c4_10196.txt | In statistics and control theory, Kalman filtering (also known as linear quadratic estimation) is an algorithm that uses a series of measurements observed over time, including statistical noise and other inaccuracies, to produce estimates of unknown variables that tend to be more accurate than those based on a single m... |
robotics/8895_80ceca0747858829_14.txt | In our experiment, we explored how subconscious biases related to socioeconomic status (SES) affect sentencing decisions. We hypothesized that people from lower SES backgrounds would receive harsher sentences , and that participants would take less time to assign sentences to low-SES individuals. To test this, we creat... |

robotics/57e4b6b9_6370.txt | Advanced algorithms: in the field of path planning for dynamic environments, the Strategy-based Dynamic Object Velocity Space (S-DOVS) model introduces obstacle velocity vectors to construct a velocity space representation that integrates both spatial and temporal characteristics. This approach significantly improves t... |

robotics/1266_e26caa74eb27f4da_105.txt | Reversible architectures have been shown to be capable of performing on par with their non-reversible architectures, being applied in deep learning for memory savings and generative modeling. In this work, we show how reversible architectures can solve challenges in parallelizing deep model training. We introduce PETRA... |
robotics/6cdd5b51_6381.txt | 3.2. Typical Paradigms and Comparative Analysis of Obstacle-Avoidance Algorithms in ROSIn the ROS navigation system, obstacle-avoidance mechanisms are primarily based on local path planning. Classical approaches can be categorised into three main types: heuristic methods (e.g., Dynamic Window Approach, DWA), optimisati... |
robotics/4c454da7_6906.txt | As demonstrated in simulation, we aim to show that the initial policy s performance can help predict if a minimum-time task can be learned swiftly and consistently with real robots as well. We employ a carefully tuned setup to showcase learning using the minimum-time formulation on four held-out robot tasks. After anal... |
