Engineering

A pre-programmed robot has to be employed for collecting soil samples from agricultural farms. The robot moves along a pre-assigned path to collect samples. For the purpose of navigation, suitable sensors have to be employed. The accuracy of the travelling path from the actual co-ordinates should be less than 0.5 m. Although GPS is the usually employed method for navigation purposes, the accuracy of GPS is between 1 to 10 m (which is very low). Assume the size of farm is between 10 to 20 hectares Please note that this is not a project nor some assignment. I just want to provide some typical scenario Could someone suggest some suitable navigation assistance sys…

I can understand the working mechanism of a 2-way or 3-way electrical switch. However, would like to know if a 2-way or 3-way switching mechanism is possible with a electronic circuit? Also, if it possible with a combination of mechanical switch and electronic circuit (means one of the 2-way switch is a mechanical switch and other switch is an electronic circuit) Regards

So far I have learnt that automation engineers replace man power with machines/robots, does this mean automation engineering is the same thing as robotics engineering? I have done some research and found they done the following: -CNC -CAD/CAM, Design Software such as Solidedge -PLC -What else do they do? I heard they also do electronics, what type of things would they learn? Also, is this more geared towards electrical or mechanical engineering?

I just saw an incredible news story on TV about a car that drives itself. It uses GPS and for "fine-tuning" has a spinning dome on top of the car with lasers scanning the surroundings. It has a nearly perfect image of all sides of the car, simultaneously, which is something humanly impossible. The car steered and accelerated on its' own, at rather high speeds, around an obstacle course, with perfect results. According to the inventor, the driverless car is not far away. It is invented by Sebastian Thrun of Google.

as of right now there really can't be any underwater development in terms of real estate and cities such because transportation would be difficult. standard internal combustion is out for obvious reasons. nuclear is out for a publicly available transportation method for equally obvious reasons so what would be kind of propulsion would work best within the restraints that it has to travel long distances most likely aprox. 200 mi and pressure at whatever depth the destination would be located at presumably at depth no greater than 400 feet. without a recharge/refuel has to be affordable to people who are not necessarily extremely wealthy. and be able to handle wave…

I'm making a small vehicle that has a steam propelled aelopile. THe aelopile spins a propellor. How much steam pressure would be needed to move around a 1kg weight about a meter or two?

What if there is a grenade, that causes little to no damage to its surroundings, but releases a gas that removes the oxygen from the surrounding areas to take away the fires life source? Something firefighters can use without entering a room that is full of fire.. it think it would be amazing to have it, and someone should design one, or even create one. Anyone else think its a good idea?

Hi all, I have power load data for a specified period (about 35 days) , I need to model it using neural networks and then fuzzy logic. for example for the first day: Time Interval Load 9:02:01 183 9:22:14 198 9:42:27 195 10:02:40 198 10:22:53 203 10:43:06 190 11:03:19 184 11:23:32 219 11:43:45 227 12:03:58 232 12:24:11 258 12:44:24 218 13:04:37 213 13:24:50 211 13:45:03 215 14:05:16 233 14:25:29 223 14:45:42 220 15:05:55 232 15:26:08 224 15:46:21 233 16:06:34 236 16:26:47 223 16:47:00 223 17:07:13 223 17:27:26 237 17:47:39 241 18:07:52 262 …

Bit of a weird one, I have terrestrial digital TV though and aerial and booster. I noticed some interference on the TV ('blocking') as i was playing a youtube video. However when I paused the video the interference stopped and I found I could cause or stop interference by pausing or playing the video!! Weird I thought. The signal is not great on this TV channel but it usually OK. I also tried playing a video in VLC player but that caused no interference? Even weirder I tried other youtube videos and they did not seem to cause interference, certainly not anywhere near to he same extent. The video in question was. I even tried another U2 video whic…

How do you know which compacitor to use? Since on the compacitor it is measured in micro-farad, how do you know how much amps or voltages it can store?

How exactly does the message signal get imparted on the carrier spectrum to reach its destination?

I was wondering if it is possible to create a new type of spring or device that stays the same energy output as it's is being compressed? normally when you compress a spring the more one compresses it, the harder it is to compress.

Hey Guys, I've got a question. People who usually created medical devices were electrical engineers end etc.... But now there is a special major in Germany call the new Medical technology, which i am studying now... . Do you guys know how the technical term called in the US for this major? It is not biomedical eng.!!! Does this special major exist in the US??? Thx!! )

If you had to brand a planet use'n only the atmosphere how would u do it? Rephrase:Lets say u had to find out what planets out there had Air but u could not go there u have to send something to the planet that would react forever to an atmosphere and let u know that it has found one with what and how would u do it?

The concept of carbon capture and storage is something most people are aware of. It refers to a technology used to address problem of CO2 emissions by some the world's largest offenders - namely the fossil fuel industry - by sequestering and storing large amounts of the gas. Over the years, many methods have been developed to help achieve this, all with varying degrees of success, as per the below flow chart: [From here] I'd like the focus of this thread to only be on one of these, specifically metal organic frameworks (MOF's). For those who do not know what these are, the wiki article on them is fairly informative. The major issues in developing a way to capture…

Hello, I have an interesting problem I need help with. I am trying to develop an optimization for a process that requires eigenvalue calculations on several (sometimes thousands) of matrices. These matrices have some special properties. 1. The matrices are Hamiltonian. 2. The matrices are symmetric about the main diagonal. 3. The matrices are mostly sparse. 4. All off-diagonal elements are either 0 or 0.05. 5. The 0.05 elements come in bands. 6. Between iterations, all off-diagonal elements stay the same. That is, only the diagonal changes between iterations. What I am wondering is, if I find the eigenvalues of the first matrix, can I use …

Hello all, I humbly ask for some assistance from someone who's more capable when it comes to science, I'm a work with my hands type of chap and the science behind things takes a bit of grasping for me to understand sometimes. So here is what I'm trying to do and where I would very much appreciate some help: I am building a steam boiler: It will be made of stainless steel and contain two heated tubes to boil water. These are the dimensions: W 25cm H 25cm D 10cm So a cuboid with two pipes running the 25cm length. The heated pipes are 800F or 427C, without the water/steam touching them. It will have a display to show the internal pressure, a b…

My next battery operated german toy, may need to wait a little for it, but been waiting way too long for a real flying saucer on the market. I will settle. Happy drooling ! -----> http://www.e-volo.com/Home.html

I learnt that the Bluetooth Low Energy will be utilizing the Star-Bus Topology. I tried to google the facts, merits and demerits of Star-Bus over Mesh Topology. But in vain. Would appreciate if someone can provide appropriate facts I have one more doubt on Star- Topology. Here, all the nodes are connected to the central hub. Is it possible for one node to make contact with another node through central hub? Regards

Please take my survey on genetic engineering. i am writing a research paper and requires this survey Greatly appreciated. Thank you

I am in my first years on high school (no points on guessing witch year) and I am very interested in robotics, but I don't really now that much about physics and technology ect. If there is anything you can tell me on the basics of it or anything else on robotics please tell me!

I am currently studying engineering at a college level and am thinking of moving into renewable energy at a degree level in the future. I am here because I have read a lot on this forum and realised many people on this forum have very good knowledge about renewable energy, I just wanted to see your opinions on what you think he future is like for renewable energy (concentrating more on wind power) and am I making the right decision going into this sort of engineering? I am planning on doing a foundation degree in renewables and then moving it on to a honours in mechanical engineering, after this I plan on taking it further to a masters degree level and am confused if I …

I was wondering if there is a power meter with detector that can accurately measure under 1 picowatt in the visible range 200 to 1100nm?

I have two questions: (1) One way to go about water purification is through reverse osmosis. Some sort of pump is used to apply a pressure on the reverse osmosis membrane. Is it possible to use osmotic pressure to act like the pump? An example is a system that has distilled water and the solution that needs to be purified in a tube separated by a semi-permeable membrane that only lets water pass through. There is a second membrane that closes off the solution (The solution is contained between the two membranes). There is an empty tube on the other side of this membrane. Will the distilled water create enough pressure build up in the space contained between the two m…

Greetings science girls and guys. I just had a question about solving the problems with my newly constructed faraday cage, trying to be a frugal as possible to still afford to feed my children. I will start by outlining the problem, followed by the intended solution, and the 'Fail Day' results: I have been working on constructing a harmonic scalar wave generator in hopes of being able to manipulate my brain wave patterns and force theta or beta wave patterns at will. The device is constructed and it seems to have some effect but the chaotic energy field that it emits is clashing with the low frequency scalar waves that ride the microwave transmissions from the cel…
