robotics/854_aeed479c586722c5_569.txt | Nancy and I spent Monday through Thursday of last week visiting friends who have a house in the Sierra about halfway between Fresno and Yosemite. On Friday I removed the leaking master cylinder from the flap synchronizer, but did not have time to do anything with it. It's not actually clear where the leak is -- I thoug... |

robotics/1190e9ab_9730.txt | B390 aluminum is a die-casting alloy that design engineers specify as an alternative to A380. It allows them to cast components with improved wear resistance. Are you interested in B390's composition, applications, and suitability for your die-cast part? Read on for... |
robotics/f7f9f889_9600.txt | Pros: Generally speaking, stripe structured light cameras can provide higher quality images at near range compared to stereo vision or ToF technology cameras, with higher accuracy and precision, because the projection of patterns provides clear, consistent textures that facilitate point-to-point matching. Cons: Since p... |
robotics/5116_532aad47262e4780_29.txt | The DMP does the rotation angle calculations for you, which can save your program from having to do them. It is able to compute rotations of more than 180 degrees, and can return the rotation angle information in many different formats, including quaternions, euler angles and yaw-pitch-roll among others. You can use th... |

robotics/22c6125d_7083.txt | (3) θ 3 : To address this problem, it is essential to first compute the transformation matrix T 2 0 between the coordinate system E X 2 Y 2 Z 2 and the base coordinate system. The angle of θ 3 is the angle between the projection of E W onto a given plane X 2 Y 2 E and the X 2 -axis within the coordinate system asso... |
robotics/02b1066c_10939.txt | Worse than that, if the model isn t perfect (which it never is!) the act of predicting into the future causes additional uncertainty. The further into the future we have to predict, the more uncertain it becomes and so the prediction error covariance grows over time. We specify how the uncertainty grows with the proces... |
robotics/21338_2e8fbf99c1add697_28.txt | In this paper we leveraged on DT to define three picking strategies, i.e., completion points, which influence both the efficiency of picking and outbound loading. This approach allowed to dynamically support the choice of completion point for the sequential picking process within an SBS/RS. During the case study, at th... |

robotics/737f6ab1_7377.txt | To validate the accuracy of the proposed TSOA, we compared the IK solutions generated by the GPM with those obtained using the TSOA. Figure 8 shows the End-effector trajectories generated by the GPM and TSOA methods compared to the desired path. The trajectory generated by the GPM shows increasing deviations from the d... |
robotics/b439e9a3_10416.txt | This results in the predict and update phases of the Kalman filter written probabilistically. The probability distribution associated with the predicted state is the sum (integral) of the products of the probability distribution associated with the transition from the ( k 1)-th timestep to the k -th and the probabili... |
robotics/9456_c0c6d1e40d06c3d8_9.txt | The pose data from WhyCon can be used as feedback for external control algorithms. The authors in [9] show that the proposed algorithm in WhyCon marker detection can find patterns approximately one thousand times faster than traditional methods. The fast update rate of the WhyCon algorithm, 80 to 100 Hz, made it suita... |
