The experimental platform consists of a cylinder, a force transducer (PBCL, range 200 700 kg, Zhongjing, Shanghai, China), an inductance micrometer (TESA-TT20-GTL22, range 2 mm, resolution 0.1 μm, TESA, Switzerland), two aerostatic bearings with a SMA... |
robotics/21338_ffcd46c10cd05485_23.txt | Background When the human body is introduced to a new motion or movement, it learns the placement of different body parts, sequential muscle control, and coordination between muscles to achieve necessary positions, and it hones this new skill over time and repetition. Previous studies have demonstrated definite differe... |
robotics/21338_ffcd46c10cd05485_250.txt | The authors quantified, first, the effect of misclassified controls (i.e., individuals who are affected with the disease under study but who are classified as controls) on the ability of a case-control study to detect an association between a disease and a genetic marker, and second, the effect of leaving misclassified... |
robotics/854_bfbc7fe81559e716_698.txt | Since we chose to build on the swerve platform that we developed over the summer, we needed to make some additions to the code for the swerve platform. The swerve module is built up of two separate rotating parts, a platform, or as we like to call it, a frame, and we have the swerve module itself. While coding the swer... |
robotics/78c21779_8526.txt | The sum of the entries on the main diagonal of a matrix is called the trace; it does not change if we reorient the coordinate system, and always equals the sum of the eigenvalues. This has the convenient implication for 2 2 and 3 3 rotation matrices that the trace reveals the angle of rotation, θ, in the two-dimens... |
robotics/854_bfbc7fe81559e716_193.txt | Then we realized a more pressing issue. Since torque is equal to force \* arm length (T=FR), and the force on our robot is only the force due to gravity (F=mg), we had a torque on the lift equal to T=mgR. **Then, as the lift was mounted at the very end, the torque on the arm was at its absolute maximum.** And, while we... |

robotics/d65cd5fa_6611.txt | With the optimized FlexHe (Type 4), the constant amplitude load fatigue analysis was carried out. By using the displacement of 25 µm and the estimated reaction force (11.5 N) from the simulation study, various parameters (i.e., alternating equivalent stress, safety factor, biaxial indication, fatigue sensitivity, fatig... |
robotics/10312_c73789492ecb27ec_39.txt | Throat microphones, or laryngophones, are contact microphones that absorb audio vibrations generated by the larynx directly from the user’s throat using the neck-mounted sensors. While standard microphones pick up sound vibrations that propagate through the air, capturing at the same time background noise, throat micro... |
robotics/854_bfbc7fe81559e716_188.txt | Today, we went to the Travis H.S. Night to talk to prospective freshmen about our robotics team. The format of the night was this: four twenty-five minute periods, with twenty minutes about SEM and five minutes about robotics. To fit this time schedule, we condensed our usual recruitment presentation down to five minut... |

robotics/854_bfbc7fe81559e716_18.txt | Omar, as you said, we’ll probably still be meming around by the time this all ends. You have been a brother to me since we started really talking to each other back in middle school. It has been fantastic seeing how you’ve branched out being a part of this team. I know you don’t get too much into sentimental things, bu... |

robotics/854_aeed479c586722c5_248.txt | I got back from Cape Cod Tuesday at midnight. Yesterday I drained the oil, and finally discovered, after having this airplane for nearly 12 years and changing the oil I don't know how many times, how to do it without spilling a drop. The location of the sump drain just above the top of the nosewheel leg makes it diffic... |
