Perhaps the most aptly named project on this list, the Energy Autonomous Tactical Robot program sought to create robots that could feed off plants just as animals do. EATR<\/a> would have enabled robots to remain in surveillance or defensive positions without resupply much longer than humans or robots with more limited power sources.<\/p>\n \u201cWe completely understand the public\u2019s concern about futuristic robots feeding on the human population, but that is not our mission,\u201d Cyclone Power Technologies CEO Harry Schoell said in a press release.<\/p>\n Before the project stopped development in 2015, its engineers estimated that EATR would be able to travel 100 miles for every 150 pounds of biomass consumed.<\/p>\n 2. Houses that repair themselves<\/strong><\/p>\n Imagine soldiers fashioning buildings and fortifications out of lightweight scaffolds instead of plywood, two-by-fours, and heavy sandbags. Then, those scaffolds quickly begin to fill in with durable material all on their own. And when that material is damaged, it grows right back to where it was.<\/p>\n That\u2019s the goal of DARPA\u2019s Engineering Living Materials program<\/a> \u2013 to create building materials that can be grown where needed and repair themselves when damaged. As researchers make progress with 3D printed organs and tissues, DARPA hopes to use similar technologies to create hybrid materials that can shape and support the growth of engineered cells.<\/p>\n \u201cInstead of shipping finished materials, we can ship precursors and rapidly grow them on site using local resources. And, since the materials will be alive, they will be able to respond to changes in their environment and heal themselves in response to damage,\u201d project manager Justin Gallivan said.<\/p>\n 3. Lab-grown blood<\/strong><\/p>\n Blood pharming is the process of creating red blood cells from cell sources in a lab rather than inside a human body. DARPA\u2019s Blood Pharming program was projected to increase the efficiency of production and lower the high costs associated with growing red blood cells.<\/p>\n If completely successful, the program would have greatly increased access to transfusable blood for soldiers and hospitals around the world and reduced the risk of disease transmission during a transfusion.<\/p>\n The program was successful in decreasing the cost of synthetic blood from over $90,000 down to under $5,000 per unit, a 2013 press release<\/a> stated, but new information has not been released since, and the program was not listed in recent budget documents.<\/p>\n 4. Cyborg insects<\/strong><\/p>\n Unmanned Aerial Vehicles may be all the rage, but they\u2019re clunky and require people to design and assemble every piece. What if there were a way to piggyback sensors on flying creatures for free?<\/p>\n DARPA\u2019s spy bugs were part of a 2006 project that wanted to implant transmitters in insects to use them for surveillance. The Hybrid Insect Micro-Electro-Mechanical Systems program<\/a> was run by teams from the University of Michigan and Cornell University.<\/p>\n Within a few years, researchers had developed interfaces capable of controlling insects\u2019 actions. And if plain old spy bugs weren\u2019t wild enough, the insects eventually received nuclear power as well.<\/p>\n In 2009, Cornell engineers revealed a prototype of a radioactively-powered transmitter for the cyborg insects. Nickle-23 isotopes would provide ample power to the sensors and transmitters the bugs might carry while remaining harmless to humans.<\/p>\n 5. Brain implants for PTSD<\/strong><\/p>\n DARPA doesn\u2019t just focus on cool gadgets for fighting wars. The agency also funds research on solutions for the negative effects war can have on soldiers.<\/p>\n The Systems-Based Neurotechnology for Emerging Therapies program is tasked with creating \u201can implanted, closed-loop diagnostic and therapeutic system for treating, and possibly even curing, neuropsychiatric illness,\u201d according to a DARPA press release<\/a>.<\/p>\n Basically, the program wants to make a brain implant that will help soldiers struggling with PTSD, traumatic brain injuries, anxiety, substance abuse, and more.<\/p>\n Because of the ramifications of such a device, SUBNETS has special ethics experts to help them create a safe piece of neurotechnology.<\/p>\n 6. Robotic infantry mules<\/strong><\/p>\n Heavy lifting is one of the largest challenges affecting troops\u2019 health and performance. Recognizing the affect the weight of soldiers\u2019 loads can have on them, DARPA began working with robotics company Boston Dynamics to create the Legged Squad Support System<\/a>.<\/p>\n Capable of carrying 400 pounds, the LS3 is intended to deploy with an infantry squad. DARPA\u2019s website states the program\u2019s goal as \u201cto develop a robot that will go through the same terrain the squad goes through without hindering the squad\u2019s mission.\u201d<\/p>\n 7. Nuke-propelled spaceship<\/strong><\/p>\n DARPA also invests in researching space travel. Project Orion<\/a> is a program from 1958 intended to research a new means of spaceship propulsion. This hypothetical model of propulsion relied on nuclear bomb detonations to power a craft forward and was supposedly capable of hitting astonishing speeds.<\/p>\n However, DARPA officials were worried about nuclear fallout, and when the Partial Test Ban Treaty of 1963 outlawed detonations of nuclear weapons in outer space, the project was dropped.<\/p>\n 8. Mechanical elephants<\/strong><\/p>\n In the 1960s, DARPA began researching vehicles that would enable troops and equipment to move more freely in the dense terrain of Vietnam.<\/p>\n Following the footsteps of Hannibal before them, DARPA researchers decided that elephants could be the right tool for the job. They began one of the most infamous projects in DARPA history: the quest for a mechanical elephant. The end result would be capable of transporting heavy loads with servo-actuated legs.<\/p>\n When the director of DARPA heard of the project, he immediately shut it down, hoping that Congress wouldn\u2019t hear of it and cut the agency\u2019s funding, according to New Scientist<\/a>.<\/p>\n![\"\"](\"https:\/\/www.fie.undef.edu.ar\/ceptm\/wp-content\/uploads\/2020\/09\/cientifico01.jpg\")
