Jan 17 Oct 2013 Hello, Dave. These hobby servos I'm talking about here are in the ballpark of 100 ounce inches of torque, so your 800 foot pounds is like a thousand times past the scope of this discussion. Even if you were talking about less torque, this would still probably not be the place to discuss your project; yo...

After the covariances are set, it is useful to evaluate the performance of the filter; i.e., whether it is possible to improve the state estimation quality. If the Kalman filter works optimally, the innovation sequence (the output prediction error) is a white noise, therefore the whiteness property of the innovations) ...

For the vast majority of the air bearing's nearly 200 year-long history, they have largely existed in one form: the orifice bearing. Orifice bearings function by forcing air through orifices or grooves in the plate to generate their air cushion.

In order to express the relationship between the various links of the redundant manipulator, the standard D-H method is used for modeling. The D-H parameters are shown in Table 1:

The benefits of squeeze film damping are not limited to rotating artifacts, but linearly traveling ones as well. Michael Chiu of MIT developed, manufactured, and analyzed a high precision stage built on vacuum replicated air bearing pads and compared it against a standard roller bearing system. Dr. Chiu used a drive po...

curate. This is the trade-off that is made in return for extremely good maneuverability and traction over rough and loose terrain. Furthermore, a slip/skid approach on a high-friction surface can quickly overcome the torque capabilities of the motors being used. In terms of power efficiency, this approach is reasonably...

As the design and build of the robot progresses, many components must be updated to be compatible with the current design. The logarithmic spiral, which was used to linearly decrease the load on the elbow with a bungee cord, is one of these. The article for the original design is numbered as the 45th post in the engine...

…To continue further, mere presence of black holes is quite indicative of existence of substance inside black holes that do no obey planck constant and other limits at micro level. Same is true when we talk about dark energy or matter that means we are not sure about “the dark” form of energy or matter which should hav...

Output functions are used to map the "logical functions" of an airframe, such as Motor 1 or Landing gear, to physical outputs like FMU output pin 2. This makes it easy to use a particular output pin for almost any purpose. Some functions are only relevant to particular frames or output types, and will not be offered on...

In the course of raising and lowering the flaps I found that I have not been allowing the hydraulic pump to run long enough after the flaps reach the retracted position to completely equalize hydraulic fluid volumes in the master-to-slave lines, and as a result, for reasons that I do not understand and very likely neve...

What with the removal of a wisdom tooth, lots of writing to do, the kitchen floor (still scraping; I can do three square feet an hour) and an unusual amount of software support needing to be provided to some new customers, I haven't been to the airport much. I did, however, do a cold compression . The engine has about ...
