innovative-drone-for-nasa

A drone is a pilotless vehicle which can be guided by remote control, or can be navigated automatically based on pre-programmed software. They are used in many scientific and civilian projects. Can be found in numerous shapes and sizes. The past few years drones are becoming more and more popular. The use of the drones has grown quickly in the recent years because they can fly for many hours and they are much cheaper. Also there is no flight crew in it that can be brought to danger. We Aim to find new and much more efficient methods of drone construction and by taking examples from drones,we may help to find new ways of transport for people and to make exploring of the galaxy very easy. Why Zero Gee Bee Challenge? The whole concept of constructing and using a drone is new on the technology market and for sure, very interesting for the master organizations such as NASA. By choosing to work on this project we knew that we are putting ourselves under huge responsibility and pressure, but yet we as a team felt ready to express our creativity and use our knowledge in the field of Physics, Programming and Simulation to create the best drone for zero Gravity. Drone Flight The drone flight is based on Bernaulli’s principle. The fluid environment (air) avails the usage of propellers. The logic behind the movement availability is pushing the drone forwards by exerting pressure onto the air. The air basically flows through the propellers. We have 2 propellers on the sides which are responsible for rotation of the drone (by exerting torque in same direction) and moving the drone forward or backward (by exerting equal torques in opposite directions). Some of the work done by the motors we expect to be wasted released as heat energy in the environment, which is why our motors would have to do additional work equal to the energy wasted. The drone’s payload The package that is supposed to be lifted off the ground will be carried by a specially designed metal grabbing “tentacles”. There are four “tentacles” that are going to be called grabbers from now on in this head. They are going to be made of carbon fiber and because of this relatively low weight of the payload area of the Drone, the package will be lifted with less energy, which means that less electricity from the batteries will be spent on the lifting of the package. The lowest part of the grabbers are going to be made from polished steal with really thin ends and because of the polished area, the friction is really low. Because of this, any object with irrelevant form can be lifted and hold inside the payload. From the polished metal ends upwards, the area will be covered with Synthetic setae. Synthetic setae is a model of material that has the same characteristics like a gecko’s skin. This S.S.-layered area has high friction and having this as a factor, the object inside is stable and it doesnt move a lot around. High friction as a factor enables the stability of the body inside the payload. Software and Hardware The software and hardware of ZERO GEE BEE is developed in two parts : software application and software simulation . -Software Simulation With the simulation , created in WebGL using THREE.JS. In our little simulation we will see how our prototype can: fly , move , use the sensor to determine a spacecraft environment (zero gravity) and so on. -Software Application Within the software application we can control our device to send and receive a package, control all elements on individual model , and we can manipulate with the sensors, engine, propeller, battery, the flying, catch package, receive some error (fatal or hardware) etc. One of the best innovations that we implemented is the Synthetic setae material. It’s based of the toes of a Gecko lizard. To have maximum and efficient grip we have covered the inside of the catcher (the “hand” of the Drone) with this material. Sensors PIC PIC is a family of modified Harvard architecture microcontrollers made by Microchip Technology, derived from the PIC1650 originally developed by General Instrument's Microelectronics Division Early models of PIC had read-only memory (ROM) or field-programmable EPROM for program storage, some with provision for erasing memory. All current models use Flash memory for program storage, and newer models allow the PIC to reprogram itself. Program memory and data memory are separated. The hardware capabilities of PIC devices has the range from 8-pin DIP chips up to 100-pin SMD chips, with discrete I/O pins, ADC and DAC modules, and communications ports such as UART, I2C, CAN, and even USB. Low-power and high-speed variations exist for many types. The manufacturer supplies computer software for development known as MPLAB, assemblers and C/C++ compilers, and programmer/debugger hardware under the MPLAB and PICK series. Third party and some open-source tools are also available. Some parts have in-circuit programming capability; low-cost development programmers are available as well has high-production programmers. Our Team Enigma team is a group of people from different nationalities, gender, age and fields of studies. Almost all of us have never met each other before. In a period of 48 hours we joined our knowledge, skills, creativity and techniques to solve an NASA Challenge for 2015. For all of us this kind of project was a first time experience and it was more than just excitement.
