HUMAN/ASTRONAUT

Our approach in improving astronaut enviroment is in improving materials and way of using sensors and their circuits.

NEW MATERIAL - REPLACING METAL CONDUCTORS:

Replacing metal conductors with liquid conductors. Material based on carbon paint is an ideal conductive material that will conduct low current of spacesuit signals. The best use of liquid conductor in space is his mobility and posibility for astronaut to very quick change circuit of the suit just by erasing the old circuit and drawing a new one. This electronic feature will adjust spacesuit to different locations, terrains and missions. Using this material we will change accesebility of electronics in space and simplify electronic platforms. Electric circuit on gloves is made of liquid conductor.

SENSORS

• Sensor that measure distance of objects in space and indicates objects near astronaut alarming him to danger. Objects like space station and other astronauts will be marked, and shown as known not dangerous objects. This kind of sensor is based on low power laser and motion sensor (microwave).

• Sensor that measure radiation. If radiation increase on dangerous level, sensor will indicate and send sound alarm to astronaut. Also sensor will indicate bright light, and if brightness is on dangerous level, electric (servo) motor will bring down astronaut visor, to protect his eyes

• Sensor that measure astronaut vital functions and send the information of his health to space station where the crew will be able to realese medicine drug from the oxygen pipe direct in his lungs in to blood.

• Sensor that detects fire in space station and send information to astronaut.

ROBOTS

Sensors on the robot will indicate Astronaut about incoming danger ( indicating dangerous flying objects, radiation) robot will always record his routes and send directly video signal to astronaut and space station where it will be saved.

USING TEAM OF ROBOTS:

Robot will always be on the distance from the astronaut that astronaut can have enough time to leave dangerous zone. Team will be made of four (Alpha, Beta, Gamma, Delta) robots. Beta will replace Alpha after he spend his fuel etc.

WHAT WE CREATE FOR 24h (video link):

In this task we used solar panel to indicate presence of the radiation, output voltage of the solar panel will increase if there is more sunlight falling on the panel. When we go outside where is more sunlight/radiation solar panel will activate the radiation alarm.

Also we put sensor that measure temperature/humidity, flame alarm, everything we can see in our control station (notebook in this case).

Emergency button - This button is made of conductive carbon paint, we used gloves as a base for the paint, the gloves represent small part of our sensitive spacesuit. When the button is pushed it sends an information to the space station that turns on a light alarm that indicates the message "Help I am in danger"

ABOUT TEAM:

Team members: Valerija Spasojevic (22), Dusan Gladovic (19)

Valerija is a web developer/designer, she finished “Polytechnic” school for new technologies where she studied Robotics. Now she has her own company in field of web development. Robotics was always her passion and she often works on her own research projects. NASA hacakaton was a great oportunity for her to show her ideas and skills and also to have some fun.

Dusan is a CAD Drafter/designer he finished “Polytechnic” school for new technologies where he studied Mechatronics. Now he is working as a freelancer and as an online CAD Teacher. Dusan loves all about science, his wish is to work on a large scientific projects where he can work hard in team working atmosphere. NASA hackaton is a great fun and oportunity for him.

Valerija and Dusan went together to school, where both joined to the robotic section and represented school on lots of presentations and fairs. Back in school days they worked very good as a team, also today Valerija is there to solve software problems, type the codes and compile the programs. Dusan works on hardware, electronic ciruicts and mechanics.
