Dear Sirs, I read with great interest about your project - EELS: "NASA robot-serpent that will explore the ice and ocean on the moon of Saturn".

JPL's Snake-Like EELS - https://www.jpl.nasa.gov/news/jpls-snake-like-eels-slithers-into-new-robotics-terrain

As a concept, the idea of snake robot for such project is correct. This is the best option of a robot for such research.

Technically, it is implemented by you at the level of student homemade and it will be absolutely inoperable, in the conditions for which it is intended.

What are the main problems?

The designers, judging by the picture, proceed from the fact that the cracks in the ice on the moon of Saturn will be similar to the cracks in the earth's ice.

In fact, this will not be in the such case - two/thirds of the volume of the crack will be filled with dendrites of water frost.

The robot you presented will also immediately be covered with a similar frost.

As a result, its hinged joins which are difficult to make hermetically will be frozen and jammed, and the rotor coils covered with melted ice will form personal ice tubes around themselves and lose traction. It will also be impossible to pull this robot back.

The energy consumption of such a robot will be unacceptable, and artificial intelligence will be required to control it more complicated than to control the hadron collider (with corresponding energy consumption)

In 2000, I was engaged in a similar topic, though not for the space program, but for mine clearance and rescue operations.

Why I didn't carry out it in practice?

By this time I already lived in a corrupt Canadian swamp and I was very reasonably told - "we don't deal with such nonsense, especially those proposed by a person who does not EVEN have a scientific degree, but, as for example, if you can offered, a machine for cutting dough for cakes, It would be of great interest to us.".....

What exactly was proposed by me and how did it differ from your project?

It was proposed - patent applications No. 2,448,135 ...01.2004

Abstract

The method of moving of the self-propelled connective device of considerable length is based on the change of mutual positions of the parts of the connective device having resilient thorns. In some particular cases, it can be only one unit having two groups of thorns which change their positions with respect to one another. The sloping of the thorns in relation to the axis of the connective device is selected depending on the chosen direction of motion.

Sketch_1: 1, 2 - length change gear of the unit; 3 - unit's part having thorns; 4 - connector of the units; 5 - gear of thorns position changing.

The self-propelled connective device consists of one or several units. The thorns and the length change gear are located on each unit of the self-propelled connective device. The thorns may be located all along the unit or on its separate parts. The thorns are sloped in the direction opposite to the chosen direction of motion, and they may resiliently bend in relation to the surface of the unit. The resilient thorns prevent the motion of the device in the direction of the thorn sloping and they allow the unit to move freely in the opposite direction.

Under the action of the length change gear and depending on outside influence, the unit either pushes forward its own part having thorns which is located ahead of the length change gear or pulls to itself all parts and units located behind the length change gear. A unit's part having thorns grips the ground and the obstacles with the help of the thorns both during the fulfilment of its own motion and when it stands still, and the driving part of the connective device is pulled up towards it.

The robot works by neutral gas pressure waves generated by the control module and guided through coaxial tubes (they are not shown in the drawings).

Working gas is not consumed.

The helix formation (bending) is carried out by four parallel bellows inserted into each studded part (they are not shown in the drawings).

The system carries out the self-balancing depend of the maximum cross section at each location of the crack.

When reversing, the robot moves backward along the path without requiring control.

The working material for the manufacture of the robot is carbon fiber and polymers / composites suitable for work in a given environment and temperature range.

With such a scheme of the robot, the control system, except for the analytical and scientific part, can be minimized.

I would make his stationary control module not on silicon chips, but by ceramic logic elements as mini Creightons (As far as I know, Creightons and their modifications are still manufactured by Perkin-Elmer Components).

This will avoid problems from the impact of high-energy particles acselerateed by Saturn's magnetic field.

The length of the robot can be increased indefinitely, including in automatic mode.

I assume that, judging by the width of the cracks and the height of the geysers (the possible level of overgrowth of cracks by dendrites of water frost), the upper surface of boiling water will lie at a depth of 100-150 meters

I do not want to create a company and start the carry out of this project, since now the scope of my interests lies in another area - The Garbage Utilization In The Sargasso Sea (8) http://samlib.ru/k/koganickij_g_a/index_3.shtml

But I can take over, by remotely, consulting and general TECHNICAL management of your group, subject to payment under the contract, or, that more interestingly for me, if you take over the sponsorship and promotion of my main project.

Please note that YOUR sponsorship in the project "The Garbage Utilization In The Sargasso Sea By Waste-Free And Self-Sufficiency Technology" can bring you a significant image benefit.
