robotics/da01b090_0494.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/6ffe6548_9704.txt | T Slot Aluminum Extrusion T-slot aluminum extrusions are extremely useful for a wide range of framing applications. T-slots can be used for any number of structural applications, and require no welding or special tools for assembly. Frames built from aluminum instead of steel also benefit from the aesthetics of the met... |

robotics/83c27ef4_6794.txt | 2 Preliminaries Dense reward via reward modeling. Reward modeling learns a scalar function r (x,y)r(x,y) that evaluates the quality of a response yy given a prompt xx. Based on the Bradley Terry model (Bradley Terry, 1952), the reward function is typically trained on pairwise preference data by minimizing ℒR 𝔼(x,yc... |
robotics/1211_fe650460e2acb790_313.txt | The objective of this study was to evaluate differences in driving performance, visual detection performance, and eye-scanning behavior between glaucoma patients and control participants without glaucoma. Glaucoma patients (n = 23) and control participants (n = 12) completed four 5-min driving sessions in a simulator. ... |
robotics/aa036145_8401.txt | The problem of singular alignment, the mathematical analog of physical gimbal lock, occurs when the middle rotation aligns the axes of the first and last rotations. It afflicts every axis order at either even or odd multiples of 90 . These singularities are not characteristic of the rotation matrix as such, and only oc... |
robotics/14178_d4eee9ddd5e6add2_133.txt | where f is the focal length. As you can perceive, this formula can also be used to estimate the distance to an object by knowing the focal length and the current distance of the image plane to the lens. This technique is called depth from focus. If the image plane is located at distance e from the lens, then for the sp... |

robotics/854_bfbc7fe81559e716_15.txt | Evan, since day one of Iron Reign, you’ve had a direct impact to both the team’s success, as well as my progress as an individual. You’ve grown to become such a mature, and hardworking person. Seeing you take more of an assertive and self-motivated role on the team made it so much easier for us to be successful. Explor... |
robotics/a9b80a1e_0632.txt | From our aerodynamic experiments, we deduce an optimal placement of the drone in an air duct. However, even at the best position, the drone must contend with the turbulences while maneuvering in close proximity to the walls that surround it in every direction. In such a situation, precise position control is key, as ev... |
