robotics/2885_33c4da2a7541fc56_51.txt | Bentley and BMW’s First Gig Was in the Sky Before the war, Walter Owen Bentley and his brother, Horace Millner Bentley, were car salesmen in London. Deep down, however, Walter had always wanted to design and build his own cars, not sell other people’s. One day, in 1913, he noticed an aluminum paperweight and an idea wa... |
robotics/1211_fe650460e2acb790_327.txt | The number of robotic surgical procedures has been increasing worldwide. It is important to maximize the cost-effectiveness of robotic surgical training and safely reduce the time needed for trainees to reach proficiency. The use of preliminary lab training in robotic skills is a good strategy for the rapid acquisition... |
robotics/61f12ec2_7862.txt | I wanted a servo to do about 400-500 degrees. All normal servos only do 90..200 degrees (and never tell their range in the specs). I ended up with one of the winch servos which also showed strange behaviour for the first movement after a direction change. |
robotics/14178_d4eee9ddd5e6add2_237.txt | and SLAM (section 5.8). Conversely, RANSAC, HT, and EM seem to produce many more false positives. This is due to the fact that they do not take advantage of the sequential ordering of the scan points and therefore they often try to fit lines falsely across the scan map. Their behavior could be improved by increasing th... |

robotics/854_bfbc7fe81559e716_636.txt | The main code task for today was creating collision detection for the UnderArm and the main Crane. This would add another layer of safety to make sure that our robot doesn't hit itself while it's controlled by Inverse Kinematics. We initially started by creating a line of no pass halfway between the main chassis and th... |

robotics/854_bfbc7fe81559e716_254.txt | Internally, `StateMachine` uses instances of the functional interface `State` (or some of its subclasses, `SingleState` for states that only need to be run once, `TimedState`, for states that are run on a timer, or `MineralState`, for states that do different things depending on the sampling order). Using a functional ... |
