My robot will be able to turn sand or dirt into edible food and or cleanse water. The way this would work is you’d take the sources around you so either one of the above and place it into the top box of the machine from there it’ll be converted into edible food. it will be run on solar batteries to avoid any sort of problems with electricity- they'll last for about 12-16hours at night without sunlight.

These machines can be placed all around cities and rural areas in the world. helping with the problem of starvation since less people starving means less deaths around the world.

 

Function: what the robot basically does is take natural waste, such as thrown out food, plants and sometimes even chemicals and purifies them, then in another “level” of the process it takes out the natural and edible things turning it into a watery paste which can be eaten or cooked. It is purified and cleaned so it is safe. 

Placement: this can be placed in landfills, it drives around wherever it can detect natural waste and suck it in, if you place it in a landfill more trash will be taken in but not many people actually live there, so people would have to bring it to others. Placing it in poorer villages will also help, the villagers throw their trash and get food in return, but they might not have trash to throw. That will mean that they will get less food. So either of these places work based on what function you are using it for.

How it helps: by taking in the trash it does reduce the trash in the world, and it also helps feed people and helps world hunger. 9% of people suffer from starvation and this will surely help, and since the trash will taken, the earth will be cleaner too, its like killing 2 birds with 1 stone!

Other information: the extra trash will be thrown out, then all the non natural trash is left. 

This is a problem that can only be fixed if we re use the items that we know will not leave the planet for years. The time taken to make 4 liters of “food” is 1 hour, the food itself can be eaten raw like a soup and it can be cooked to form hard chunks like fries or chips. The food will taste different every time but mostly having a taste similar to bread. 
thats all i have to say about my robot.

 

Why can we not give it up? Because it tastes good.

 

But what if we create a robot that takes all the calories and bad stuff in the food and we have food that tastes good there will be a voice activator and commands with remote control. You just explore have fun

This benefits doctors in many ways. For instance, in a stroke patient, the computer can quickly tell how much brain that is at risk of dying if you do not quickly give medicine to dissolve the blood clot and tell the doctor if it is safe to give the medicine. A robot first learns how to do this (machine learning), then can do it sufficiently on their own. Global warming is also something that needs solving but that will affect the world in a long time. However, people are dying everyday from blood clots, brain tumers etc.This invention can tell doctors if it is safe to give medicine, and if it is then it could prevent harm or  save  lives.
