Robotics
This branch of technology deals with the design, development, operation, structural disposition and application of robots. Robotics is related to other sciences including software, mechanics and engineering. Current robots have the capability to move and speak.

What is the advantage of a parallel circuit over a series circuit?
In a parallel circuit the failure of one bulb reduces the light of that one bulb. In a series circuit the failure of any bulb causes all bulbs to stop producing light because the circuit itself fails. A break in a series circuit stops the current flow to the whole circuit. A break in a parallel circuit stops the flow only in that parallel branch, not the whole circuit. This independence from system loss by one failure is a parallel advantage.
Why hissing noise occur in transformer?
EHV and VHV substations tend to have a signature hum; this is due to small electrical arcs. This is normal. Most of the time this will not be audible on VHV and EHV power lines. If you are hearing this from the power line, it could be bad and the utility may want to know. It shouldn't be a risk to you, however the hum may be resulting from arcing, which can be fairly high frequency, which can mess with electronics's signals such as cell phones and radio (won't damage them, just bad reception).
What are the advantages and disadvantages of inductive proximity sensor?
The advantages of inductive proximity sensors are
- They are very accurate compared to other technologies
- Have high switching rate
- Can work in harsh environmental condition
The disadvantages of inductive proximity sensor are
- It can detect only metallic targets
- Operating range may be limited
hashing algorithm contain two components - hashing function & collision.
hashing is mechanism which generally used in random file organization to convert the record key value into address.
Does electromagnet work only on DC?
They normaly are. AC ones tend to buzz.
The core has to be of soft iron or laminate, so that the field collapses properly when the current is switched off.
Materials required to construct robot for students level?
what age?
"robot" is a VERY generic term. they can range from Lego mindstorms (great for students around age 8) to robotic arms (great for students around age 19).

Working of single phase energy meter?
An electric meter or energy meter is a device that measures the amount of electrical energy supplied to or produced by a residence, business or machine.
The most common type is a kilowatt hour meter. When used in electricity retailing, the utilities record the values measured by these meters to generate an invoice for the electricity. They may also record other variables including the time when the electricity was used.
Modern electricity meters operate by continuously measuring the instantaneous voltage (volts) and current (amperes) and finding the product of these to give instantaneous electrical power (watts) which is then integrated against time to give energy used (joules, kilowatt-hours etc). The meters fall into two basic categories, electromechanical and electronic.
Electromechanical metersThe most common type of electricity meter is the Thomson or electromechanical induction watt-hour meter, invented by Elihu Thomson in 1888.[1][2]TechnologyThe electromechanical induction meter operates by counting the revolutions of an aluminum disc which is made to rotate at a speed proportional to the power. The number of revolutions is thus proportional to the energy usage. It consumes a small amount of power, typically around 2 watts.
The metallic disc is acted upon by two coils. One coil is connected in such a way that it produces a magnetic flux in proportion to the voltage and the other produces a magnetic flux in proportion to the current. The field of the voltage coil is delayed by 90 degrees using a lag coil. [1]This produces eddy currents in the disc and the effect is such that a force is exerted on the disc in proportion to the product of the instantaneous current and voltage. A permanent magnet exerts an opposing force proportional to the speed of rotation of the disc - this acts as a brake which causes the disc to stop spinning when power stops being drawn rather than allowing it to spin faster and faster. This causes the disc to rotate at a speed proportional to the power being used.
The type of meter described above is used on a single-phase AC supply. Different phase configurations use additional voltage and current coils.Reading
The aluminum disc is supported by a spindle which has a worm gear which drives the register. The register is a series of dials which record the amount of energy used. The dials may be of the cyclometer type, an odometer-like display that is easy to read where for each dial a single digit is shown through a window in the face of the meter, or of the pointer type where a pointer indicates each digit. It should be noted that with the dial pointer type, adjacent pointers generally rotate in opposite directions due to the gearing mechanism.
The amount of energy represented by one revolution of the disc is denoted by the symbol Kh which is given in units of watt-hours per revolution. The value 7.2 is commonly seen. Using the value of Kh, one can determine their power consumption at any given time by timing the disc with a stopwatch. If the time in seconds taken by the disc to complete one revolution is t, then the power in watts is . For example, if Kh = 7.2, as above, and one revolution took place in 14.4 seconds, the power is 1800 watts. This method can be used to determine the power consumption of household devices by switching them on one by one.
Most domestic electricity meters must be read manually, whether by a representative of the power company or by the customer. Where the customer reads the meter, the reading may be supplied to the power company by telephone, post or over the internet. The electricity company will normally require a visit by a company representative at least annually in order to verify customer-supplied readings and to make a basic safety check of the meter.Accuracy
In an induction type meter, creep is a phenomenon that can adversely affect accuracy, that occurs when the meter disc rotates continuously with potential applied and the load terminals open circuited. A test for error due to creep is called a creep test.
How will robots effect our future?
Scientists are now looking into how robots will change the world in the future. The world of robotics has come a long way since the first industrial robots were introduced in the 1960s. Today, robots are used in a wide range of industries, including manufacturing, healthcare, and entertainment. As technology continues to advance, the future of robots is looking increasingly exciting.

How do you kill omochao for good on sa2b?
Best to ignore the robot chao, if you really want, try throwing it into the ocean or into space or a bottomless pit. These can work.....
Because BUMBLEBEE is cooler than anything,anyone,and any thing else possible.he is nice kind caring and one hell of a guardian.and im his biggest fan ever
How do you make alpha rex walk?
Program it on the computer (after installing software from disk). Then on the NXT, go to "my files" then to "software" and pick the program you'd like it to perform. Then push the orange button, and it will start.
What is the difference between real robots and robots in movies?
Real robots do simple repetitive chores such as build cars or computer chips. They are machines that don't move around usually, although the vacuum cleaner types do move. They usually have sensors that tell them the position of their working parts rather than eyes. They are controlled by a central computer complex that adjusts the speed of a whole series of assembly line actions to optimize output.
Most movie robots are action figures that are similar to humans. They see with eyes, they control themselves, they move around and participate in the human interactions just like other actors. Their purpose is to make the movie futuristic and add elements of danger that a human actor could not do.
How do you spend your time when you have no friends?
I usually go outside draw something or simply read a book these are some great things to do if your bored.
