High-Level Project Summary
We used A Stirling cycle system taking advantage of the gases on the Venus atmosphere and its high pressure. by replacing the combustion by a temperature change using the pressure of CO2 we will obtain electrical energy at w = 181,70 w/h, I=1,66ª, V=0,17v.With our cycle we manage to maintain an active generator for our 60 days of expeditions since in 14.7 hours we charge our 4 batteries, usimg 2 at the time; that gives us 2 hours a day for expeditions. The generator produces constant electrical energy for our electrical and electronic equipment, and the voltage sensors indicate when our battery reaches 25% of work and an automated system changes the energy source for a charged battery pair

Detailed Project Description
It is an energy storage for the rover dto explore Venus.
The project works by means of the Stirling cycle, a cycle that absorbs carbon dioxide to take it to some compressors where, by means of the plunger method, it will put pressure on the gases, thus being able to level their temperature with refrigerants, and almost finished this cycle, the next step is that this pressure passes to the turbines to generate kinetic energy and movement to these. Finally, this energy passes to the booster to power the module.
Collecting data to investigate more about the pose, what its benefits are, and also to find problems that may affect the exploration.

Space Agency Data
For the solution of our challenge we used data from the official nasa website, such as lithium batteries, the venus arrival system (Davinci) and rims made of aluminum blocks with titanium spokes and other materials that resist high temperatures on venus.
Hackathon Journey
The experience during these days working with Space Apps was unique and unforgettable because thanks to this challenge we learned a lot about the stirling cycle and about topics such as gas laws; modeling and design; electrical circuits;
Ohm's law; among others. What most inspired us to choose this project over the others was that being a robotics club, this theme would be a great challenge for it because it articulates areas such as mechanics, electricity, electronics, physics, chemistry, materials analysis, etc ...
After having clear what our challenge was we focused mainly on modifying the stirling cycle to replace the combustion by temperature change method for this to work on Venus, after investigating we recognized that we would get to have a full use of the environment of Venus as it is to work with CO2 for the proper functioning of our system; for no one is a secret that throughout a project there may be mishaps but as a team we managed to get out of this, our first idea for the batteries was to use solar energy as it is a known charging system and in one way or another viable for the system but we did not count that on Venus there are 2 layers of clouds which prevent the direct rays of the sun to reach the panels, after this and without getting discouraged as a team we decided to move forward and that is how after a long time of research the stirling cycle came to our project at the end of all we have to thank our Coach Oscar and our Coach Eduardo for giving us the opportunity and for believing that we can with this and many more projects besides helping us and always being willing to solve our concerns and above all to maintain the good atmosphere of the SuazaBots team.|
