robotics/7e625cbe_0512.txt | Servo mechanisms are not the "popular" RC-Servos (not-only). Servo is a closed-loop control, not only for motors. Even Steppers could or not be servo-motors. RC-servos are in major cases a DC brushed motor, with reduction gear and a potentiometer for position feedback, and electronic control. This is a common RC Servo.... |
robotics/42d4387d_6590.txt | Abstract Featured ApplicationAn optical system with a compact dimension for the small satellite, requiring less power consumption. AbstractFor earth observation, the optical systems in small satellites are crucial to obtain high- resolution images. However, the alignment between a primary and a secondary mirror in an o... |
robotics/1202_d14a34391eb82ba2_165.txt | **Beyerdynamic DT 1770 Pro** - First off, yes I know - not even slightly portable between their size and 250ohm rating, these are a use them at home with an amp proposition only, having said that, they are also the d back I judge all else by. Sound wise, the 1770 has great bass extension and good control. What differen... |
robotics/5116_85c6e59d1c838762_8.txt | **3s:** This is found on batteries and tells you how many cells are wired in series and parallel. Assuming we are talking about Lithium Polymer (LiPo) batteries, each cell has a nominal or "normal" voltage of 3.7v, but when fully charged, they are 4.2v, though some LiPos can go up to 4.35v per cell, and are labelled as... |
robotics/f7973ecf_0671.txt | The robot model developed in this work aims to resemble the movement of the human arm, with the ability to execute the precise, complex movements a person makes when writing or drawing. This model is not based on a specific robot. Instead, physical and mathematical formulation was applied inspired by a human upper limb... |
robotics/854_aeed479c586722c5_622.txt | Today marked some sort of milestone. I began to bleed the flap hydraulics by running fluid through them from the pump. In order to do this I first re-plumbed the system, bypassing the flap actuator lines, so that the synchronizer module was connected directly to the hydraulic pumpand reservoir. At first nothing happene... |
robotics/810afdda_9746.txt | A common misconception is that aluminum will not meet structural strength standards. In fact, extruded aluminum possesses a superior strength-to-weight ratio than steel. It is strong enough to handle most structural design applications. Overall, the light-weight structure and structural strength offer to great benefits... |
robotics/a4dce06d_10848.txt | There are many reasons why we want an accurate estimate of the state of a system. One of which is that we need it in feedback control to determine how to change the system. For example, if we are trying to control the temperature of something, we need to have a good estimate of what the current temperature is in order ... |
robotics/854_bfbc7fe81559e716_727.txt | While we've done some off-robot testing Speciminer still has a lot of trials to undergo before it can be certified and ready to go. The next step will be to put Speciminer on either the robot itself or a test rig that simulates almost the exact same conditions as our current robot. This step is being done to see how it... |

robotics/1202_d14a34391eb82ba2_33.txt | Isolation is good for a d back, but it’s not quite the best I’ve heard. The included silver plated copper Litz cable is excellent. It’s cloth covered, very malleable and the perfect length for portable use. My only real big issue with the build is the choice to use the same connectors as the Sennheiser HD800 uses. I’ve... |
robotics/854_bfbc7fe81559e716_287.txt | At the same time as the elbow joint was being done (which can be found in the article "Constructing Icarus' Elbow”) the Superman lift was being installed in the back half of the robot. The old superman system was difficult to install, but we designed it to be slightly easier. Mounting brackets were already pre-set in t... |
robotics/50e0f23e_9367.txt | - 1961 - IBM commercializes the usage of air bearings in their first generation of hard drives. Boasting error motion on the order of two millionth of an inch and 100 times more accurate than contact bearing spindles, air spindles allowed for higher data concentration, and even today, air bearing spindles are still a n... |
robotics/854_aeed479c586722c5_751.txt | Melmoth's autopilot and GPS tracker worked fine, contrary to expectation, and its speed and fuel consumption were still consistent with an equivalent flat plate area of 2.3 square feet and a parasite drag coefficient of .022. I've begun leaning early in my climb -- may as well cool the engine with air, which is free, a... |
