robotics/854_aeed479c586722c5_235.txt | Looking back over the history of oil temperatures going all the way to the fall of 2002, when Melmoth 2 began flying, I found a general pattern of temperatures around 90-110 C depending on flight condition (climb, cruise) and ambient temperature, until I installed the duct that isolated the oil cooler flow from the res... |
robotics/ebc5f742_8976.txt | This page will describe in detail the development of several different control strategies. These control systems are developed based on the quadrotor model derived in the System Modeling section, implemented in a simulated environment , and finally verified on an actual system. Lower level control systems will run at a... |
robotics/3c2ca84c_9670.txt | IPS profiles are slow-extruded to withstand high straightness tolerance forces. This enables the most complex applications. Our profile selection includes a variety of 210 T Slot profiles. They all fall into one of three profile lines: L5, L6 or L8. The ending number references the T slot groove dimension. The lines r... |
robotics/3144_6e3d36da25bc2e1d_18.txt | In Eq. 18, the true positive (TP) indicates the number of people of one gender correctly identified and the false positive (FP) corresponds to the number of people classified as one gender who actually correspond to the other evaluation group. The true negative (TN) is the total number of people of one gender correctly... |
robotics/146d113d_10990.txt | Typical motion-controller cards and modules include a motion-control IC, a microprocessor, and a DSP or custom ASIC for processing the high-speed encoder signals. The controller provides velocity and direction-of-rotation signals to the driver or amplifier, which in turn provides the proper levels of voltage and curren... |
robotics/854_bfbc7fe81559e716_711.txt | We want to better segment the time before competitions to make sure the build, code, and drive team all receive almost the same amount of time with the robot. Allocating time in this manner will allow the drive and code team to have an adequate amount of time to make sure other things are not lacking such as fine tunin... |
robotics/9456_c0c6d1e40d06c3d8_3.txt | However, nano aerial vehicles (NAVs) have garnered significant interest in educational research and initial testing of aerial algorithms due to their potential for autonomous maneuvering in indoor and outdoor environments. Since global positioning systems (GPS) are not available indoors, localization of NAV in the envi... |
robotics/1202_d14a34391eb82ba2_12.txt | Ergonomics are a strong point of the Cascade though it does come at the cost of portability relative to competitors. The headphones are in-between a home and conventional portable headphone in dimension, with very deep angled ear pads and a reasonably wide headband. In return, the headphones are very comfortable; their... |

It can be concluded that the act of collecting data and updating the neural network weights and biases has reduced the average of the absolute tracking error for each trajectory tracking when the joint backlash is added to the delta robot. By... |

robotics/854_aeed479c586722c5_666.txt | Yesterday Captain Tom Huff, the CO of the Naval Test Pilot School at Patuxent River, Maryland, stopped by on his way to the Air Force Test Pilot School graduation at Edwards, and we flew to Camarillo for lunch. I had him fly the plane on the way there, hoping for his assessment of it. Of course if he had thought it sta... |

robotics/37569c09_0079.txt | I’ve described the rover implementation that provides Locomotion capability for the Autonomous Rover. It performs reasonably well. Forward motion is accurate to ±2 cm in the direction of travel. Unintentional drift (left or right) during forward travel is bounded to ±3 cm at the maximum forward distance of 550 cm; the ... |
robotics/7688ad98_8366.txt | In three dimensions this restates in matrix form an observation made by Euler, so mathematicians call the ordered sequence of three angles Euler angles. However, the situation is somewhat more complicated than we have so far indicated. Despite the small dimension, we actually have considerable freedom in the sequence o... |
robotics/e51b300b_7003.txt | One of the complexities of the sinusoidal control approach is the precise control of duty cycle against motor angle demanded to form the saddle-shaped voltage input. This becomes even more difficult at high revolutions. A major part of the challenge is that the motor position is only accurately determined six times per... |
robotics/854_bfbc7fe81559e716_304.txt | We had some initial setbacks due to pre-manufacturing issues with the beta unit we were sent. The control board was set to the wrong address and couldn't be used. Once we got it replaced, the primary robot functions worked well. The only exception was vision. Because we lost so much time we didn't quite finish our Open... |
