# A Soil Resistivity Meter for Venus

I would like to prsesent basics of how a soil restivity meter could be designed , work , and trasnmitt data
in the rover for Venus .
We will use the 18 volt dc from the rover power supply and a mechanical shaft that rotates in high speed ,this high speed can be done with speed multiplier .
Basics
Three metallic probes exist on the one side of the body between front and rear wheel looking up the sky when the resistivity meter activated a mechanism steps down the probes mechanicly, also a torque mechanism in this part can be used to push the probes in order the edges of the probes ( edge of each probe is a metallic rotary roller thin blade ) get inside the soil separately .
The possitve wire from 18 volts dc connects in a ball bearing on the center of metallic propeler in the every edge of the propeller fin has a metallic roller the propeller is fully conductive and metallic which means that from the center that goes the positive dc 18 volt wires same dc exist in each metallic rollers.
On the center of the other side of the propeller a shaft moves the propeller , in high speed this part we could use a speed multiplier to achieve desired shaft speed .As the propeller rotates with the rollers on the edge of each propeller fin rollers hit a certain one metallic edge that edge extends with a wire , from the rotation and the space between the fins and the rollers hitting the mettaling edge comes the frequency .This positive pulse signal goes out to two or to one probe (optional) .The receiver probe which exist between the two positive probes in a same space between them , receives the noise then this noise directed transimited .A wire goes from the receiver probe in another propeller system a wire that carrys the signal is connected to a ball bearing in the center of the propeller , on the other side of the propeller a shaft rotates in high speed the propeller , metallic edge been hit from the rollers .In this part of the transmission i would like to mention desired pulse from the hit of rollers could be in khz frequency inside that pulse signal a noise exist from the receiver probe .This final signal goes to an antenna .The receiver which is exist in a satelite can first track the pulse in khz and then analyze the noise this signal carrys.

The probes output

As i mention above a second propeller system with rollers used to make a khz pulse (only for transmission ) and carrys inside this signal the noise has been received from the receiver probe between soil and transmitter probe or probes ( optional ) .
Although has a few differences from resistivity meter i believe is an option ( because of this hard enviroment) .
I could provide also more info for the step down mechanical mechanism for the probes if needed .

Note edges of each probe is rotary roller blade cutter .
Also transimitted signal that came from the receive probe from rover to satelite is the one with khz pulse this noise wil be transmited.
Example the first propeller with rollers system lets say that is adjust when is starts to rotate it will create a pulse (+) frequency about 137 hz , this frequency the distortion of this signal will be received from the receiver probe this distortion goes to a second sestem propeller only basics differnce is the wire that is connected in ball bearing on the center of propeller will carry no 18volt dc but the distortion of that will be received from the middle receiver probe and the shaft on the other side which is connected on the center of the propeller will be set to produce a rotation which will give us a result when the rollers hitting or touching the metallic edge will be for example in 1khz this noise that will be transmited in khz freq goes from a wire to a metalic extension which works as an antenna .Above over 100 km were the satelite is will trace the pulse of 1khz which this signal carrys the noise or the distortion .
if something is not clear feel free to ask thank you .
