Vehicle Running Without Motor, Nasa High Technology

The drawing of this mars rover, curiosity:



And this one is lunar rover:



As we can easily see, the engine is not planned here.

Let's take a look at the motion system of rover curiosity from wikipedia:

Quote
Mobility systems: Curiosity is equipped with six 50 cm (20 in) diameter wheels in a rocker-bogie suspension. The suspension system also served as landing gear for the vehicle, unlike its smaller predecessors.[49][50] Each wheel has cleats and is independently actuated and geared, providing for climbing in soft sand and scrambling over rocks. Each front and rear wheel can be independently steered, allowing the vehicle to turn in place as well as execute arcing turns.[33] Each wheel has a pattern that helps it maintain traction but also leaves patterned tracks in the sandy surface of Mars. That pattern is used by on-board cameras to estimate the distance traveled. The pattern itself is Morse code for "JPL" (--- -- -).[51] The rover is capable of climbing sand dunes with slopes up to 12.5.[52] Based on the center of mass, the vehicle can withstand a tilt of at least 50 in any direction without overturning, but automatic sensors limit the rover from exceeding 30 tilts.[33] After six years of use, the wheels are visibly worn with punctures and tears.[53]
Curiosity can roll over obstacles approaching 65 cm (26 in) in height,[54] and it has a ground clearance of 60 cm (24 in).[55] Based on variables including power levels, terrain difficulty, slippage and visibility, the maximum terrain-traverse speed is estimated to be 200 m (660 ft) per day by automatic navigation.[54] The rover landed about 10 km (6.2 mi) from the base of Mount Sharp,[56] (officially named Aeolis Mons) and it is expected to traverse a minimum of 19 km (12 mi) during its primary two-year mission.[57] It can travel up to 90 m (300 ft) per hour but average speed is about 30 m (98 ft) per hour.[57] The vehicle is 'driven' by several operators led by Vandi Verma, group leader of Autonomous Systems, Mobility and Robotic Systems at JPL,[58][59] who also cowrote the PLEXIL language used to operate the rover.[60][61][62] Source: https://en.wikipedia.org/wiki/Curiosity_(rover)

As we see in the descriptions and drawings here, there is no reference to the engine.

This is a simple car with an electricity motor:



As we can see, normally electric vehicles have engines. Because, as we know, an engine is required to convert potential energy into motion energy.

While preparing these rovers, Nasa did not need the engine, electrical energy magically transformed into motion energy on the wheels. High magic technology. Or, Which of you forgot to put an engine in the car? No panic! There are magicians around!

The Mars rovers did not have an 'engine' as electric motors don't need one.

You can see the wheels turning in this video, and the closeup helps show the motors within each wheel.  You can see the wires feeding power to them quite clearly.

Also that rover looks like a fragile POS. No way it would survive an entry into a planet and cope with the sand and dust.

I'll be its currently operating out at Area 51. When a photo needs to be taken they just get someone to plonk it somewhere for the best shot. No wonder the government were losing their shit at the thought of people storming it last year. Couldn't have them stumble upon the 'Mars' Rover!

I think they thought they would not need an engine/motor when they first made the electric vehicle. They thought it would work without a motor, just like television or radio. But electric vehicles were produced, and we know very well that they need the engine, just like any other. This is just one of their countless mispredictions. Maybe after this debunk some people will ask them where the engine is, and they will lose this technology! Oh, "we had this technology, but we lost it". Then they will switch to another technology enforcedly.

You are still making excuses excuserinoz. Yes it is used in the electric drive motor in the earth. So; Where is the electric drive motor a source of NASA you have mentioned. It is not exist then we are talking about it.

It is clear that this is not the case. You could still not prove that neither Mars rover nor Lunar rover has an electric motor.

You have prove that the electrical energy used in the engine is produced, that I have already mentioned it earlier that, it has. Electric energy is produced. However, this energy is not converted to motion energy in neither Mars nor Lunar rover.

You have just told something has to be but not proved it has. You are talking theorically something has to be; but the problem here, it has not; mister hastirinoz.  ;D

I am sure every sane people see this thread see how you are talking something not close to be an answer here.

The fact that NASA uses electric motors in the Mars rovers is extremely common information and very easy to find.

https://trs.jpl.nasa.gov/bitstream/handle/2014/45130/10-2485_A1b.pdf?sequence=1

"NASA will launch a 950 kg rover, part of the Mars Science Laboratory (MSL) mission, to Mars in October of 2011. The MSL rover is scheduled to land on Mars in August of 2012. The rover employs 31 electric-motor driven rotary actuators to perform a variety of engineering and science functions including: mobility, camera pointing, telecommunications antenna steering, soil and rock sample acquisition and sample processing."

"B. MSL Actuators: There are a total of 31 rotary actuators on the MSL rover. The actuators provide all of the articulation needed to move and point the science cameras, to move and point the communications antenna, to drive and steer the rover, and to collect, process and deliver solid  samples to the laboratory science instruments inside the rover body. Each actuator consists of an electric brushless DC motor, a brake, an encoder, a gearbox and an output resolver (see Fig. 2). The electric motor provides the energy to move the mechanism."

"The mobility subsystem contains 10 actuators capable of driving and steering the rover as it moves in commanded and autonomous  traverses. There are 6 drive actuators, imbedded inside the 6 wheel hubs, and 4 steer actuators, located above the corner wheels. "

Just in case there is any remaining confusion, because I see posts continuing elsewhere, here are pictures from the article I linked above and again here.

https://trs.jpl.nasa.gov/bitstream/handle/2014/45130/10-2485_A1b.pdf

"The rover employs 31 electric-motor driven rotary actuators to perform a variety of engineering and science functions including: mobility, camera pointing, telecommunications antenna steering, soil and rock sample acquisition and sample processing. "

Note it says very clearly ELECTRIC-MOTOR and one of the uses is MOBILITY.

Just to make it even clearer, the Curiosity Mars rover uses electric motors in it's wheels to move around.

Yeah, each wheel has its own little motor.  Not sure what else ya need.  This allows each wheel to move independantly of the others at different speeds while using minimal energy.  This is ideal for driving in unpredictable terrain.

Whoooooooooooosh.   ::)

He is asking if you think every single detail of something has to be included in a simplified diagram, or it doesn't exist.

If you buy a car, is every single nut and bolt listed on the sales document?

It's an electric powered rover. They didn't feel the need to point out everything on board runs on electricity because what else would it run on?

Yeah, not a lot of gas stations out there. :D

Now, some of the space probes had some propulsive thrust for maneuvers, usually using hydrazine as a propellant.  Kind of like when Wall-E used the fire extinguisher, they just spray out a compressed liquid, and don't use any of it for power generation.

But to run the spacecraft it's either solar or Nuclear power, both generating the electricity needed.  No combustion engines, no windmills, no hydroelectric, no geothermal. Sad this has to be pointed out in advance.  ::)

You forgot coal and natural gas.

And for the most part, nuclear power in space is via a radioisotope thermoelectric generators, not a fission reactor.  Fission reactors aren't the only form of nuclear power.

What? Are you mocking? This is one of the funniest theory I've ever heard. There are separate engines in four wheels. Wow! Thus, when you press the accelerator, all four engines react exactly simultaneusly and the vehicle will not be knocked anywhere, nor crashed!

Have you ever tried this method in the world to see what happens if a vehicle has four motors in four wheels? Ahahahaha! I will carry this to the believers subforum as how funny a globularist can be when trying to defend a lie.  ;D

That is how many vehicles with electric motors work. Makes it easier to provide variable torque to each wheel without the complication of a differential.

Six wheels, though I realise that counting isn't your strong point.  And yes, there is a motor in each wheel.
