The wheel

EMF is the voltage across a coil (or motor) due to changes in the magnetic field. If you change the current the coil will generate a voltage (in the opposite direction of the current). So it is not the field but the change that matters.

there is no exact answer to that you would have to do it all by yourself but what i would do is program the color sensor to start moving randomly- wich will somewhat look like dancing- which will probably fix your problem but i will warn you it is hard i just finished programing mine and it does work the thing is that making the program is time consuming

Yes if the battery can deliver enough current for enough time to be useful. You would connect the motors in parallel. If for example each motor required 1 amp and you had a 30 aHr (amp hour) battery the motors could run for about 10 hours.

then say,

"How about a swamp?"

Or say "Siri, you're the only one for me"

Logarithms are actually an area of mathematics.

Using logarithms one might ask the question, "what is the logarithm of 5 (base 10 being assumed)"

And the answer would be, you would raise 10 to the power 0.698970004 to result in 5.

The United States currently makes several "flying robots".

Research "UAV".

i can use the battery radio controller.

"Tank with spouts " may refer to either the 'settling tank' or the 'pump tank' in most sewage systems.

A motor can be connected to a computer through some type of controller circuit. Typically, such a circuit would receive input from the computer that indicates the direction and speed of the motor, then the controller would convert that to the appropriate pulses and voltages that would cause the motor to respond properly.

Depending on what you are trying to do, consider a "stepper" motor, which has 3 inputs. When power is applied to any 2 of the inputs, the motor will "step" forward a few degrees. The controller determines the motor speed by firing power transistors in the appropriate sequence to cause the motor to operate.

A less sophisticated approach is to simply turn a motor on by engaging an output transistor that operates a traditional motor. The transistor could even activate a relay if you are uncomfortable with transistor circuit design.

A popular electronic development platform is called the Arduino. It would be trivial for your Python program to send a command to the Arduino which would control the circuit.

That depends on your definition of "first technology". Technological advances, such as the wheel or the inclined plane, have been around for thousands of years. Others, such as the Microprocessor, have been around since 1974, when Intel invented the 4004.

show how to test igbt and mosfet in an easy way

i am in that class and all you need to do is set the power level to 50-100 then find the threshold of the dark and light line set that up with 4 motor blocks on top of each other then on the one on top have one motor stop while the other motor is still going same with the bottom just different motor

Transformers

Yes there is. On one of the levels at the start with GLaDOS she says she has to go, then decides to give you the quick explanation of the level. To hear the quote look it up on youtube, but otherwise, it's a quote from moby dick.

Don't build robots that could take over the world.

2. Half wave and full wave

programmed to do it and that tasks are updated every while like robot on mars ,it recieves orders everywhile like move 500 meter,turn right,move 300 meter , activate camera,send picture,hold ,etc

32x8 normally means 32 registers of 8 bit width.
