robotics/854_aeed479c586722c5_691.txt | One can, however, do a back-of-an-envelope stress analysis. Dynamic pressure at 200 knots is 132 lb/sq ft. CFD analysis of the spanwise lift distribution suggests that the tips achieve only about 60% of the CLmax of the wing at their root (BL 200), tapering to zero at the tip. With the trim flap set 20 degrees down I w... |

robotics/81b6d7ef_11172.txt | I want to try and publish a static transform between base_link and camera_color_optical_frame. Since the this transform will be static, will my camera frustum marker move according to how base_link moves? To publish the static transform, I have to follow this right? |
robotics/0086bdae_10759.txt | The Kalman filter is efficient for sequential data processing on central processing units (CPUs), but in its original form it is inefficient on parallel architectures such as graphics processing units (GPUs). It is however possible to express the filter-update routine in terms of an associative operator using the formu... |
robotics/1202_d14a34391eb82ba2_48.txt | The Cascade use the Sennheiser HD800 style of push.pull connectors, and these are angled out of the bottom of each earcup at 45 degrees. This allows for a nice solid cable connection, and naturally angles the cabling forwards so it lays more easily across the chest. The cable connectors and socket both look well machin... |

robotics/14178_d4eee9ddd5e6add2_215.txt | tify salient regions of the image first and create the representation out of this only. This approach largely depends on the detection of salient regions using interest point or interest region detectors, which we have seen in section 4.5.

robotics/1202_d14a34391eb82ba2_76.txt | ****Cable choice**** The Cascade uses the push/pull HD800 style of cable connectors, so there will be a plethora of available upgrade cables available from the usual aftermarket suppliers if you want to experiment with different cable “tones” for this beast of a headphone.

robotics/854_aeed479c586722c5_634.txt | I completed the neutral-point hunt yesterday with a flight with 200 pounds of ballast, CG at 40%. The flight was unremarkable and the resulting data set fell nicely into line with previous ones. The stick-fixed NP is evidently at FS130, which is 60% of MAC, just as DWT said. I am setting the aft limit of the CG envelop... |

robotics/c5c2d9b4_7805.txt | Hi, Chris. What does your question have to do with continuous-rotation or multi-turn servos (the topic of this post)? Also, it would be nice if you didn't call your servos servo motors given that one of the posts in the series details why not to call them servo motors. Anyway, it's completely possible for you to dest... |
