Sixth Sense Design Challenge

So we have been making slow but steady progress with our inspection system. Since this marks our completion of ten blog posts, we decided to do a brief review of what we have accomplished so far and all that is left to be done. We set out with the intention of improving the current state of the art in industrial inspection systems, but as we moved forward, we found it better to focus more specifically towards catering to the oil and gas industry. This was spurred on by positive interest from som ...
We used iNav for the purpose of flight planning. This blog post is a summary of what we learned about iNav, why we decided to use this and how we planned to implement it.   Designed primarily for racing iNAv runs on the flight controller and helps the device fly faster with more control.One of the required features was modern GPS flight modes, so we could have solid GPS Hold (where it sits in the sky) and GPS Return to Home (where it flies back to us automatically) as well as improved fail ...
In January, we decided to make our own Flight Controller, with the objective that it to be easier to tweak and customize it. However, we came to a standstill because of a few bugs in the code and compatibility issues. We tried to make an Arduino based flight controller but it didn’t come to fruition as there were some problems with the IMU(Inertial Measuring Unit - MPU-6050). We succeeded in rectifying the issue but still, there were some left with the Transmitter - Receiver coupling.  ...
While one part of the team was busy working on assembling the drone and customizing the code for the FC, another part of the team was brainstorming on how the drone could be made more robust, with our initial objective in mind: to use drones for tunnel vision. Apart from working on the structural integrity of the drone using Ansys, subjecting it to stress, wind pressure etc., fireproofing was an area that we felt work was needed upon.  We were in touch with a few people working in the oil a ...
This post is written to give a step-by-step description of how we will be implementing IR sensors and thermal imaging in our project.   The potential uses for infrared sensors, especially in cameras, are vast and include search and rescue, surveillance, crop and forest health, pipeline inspection, leak detection etc., depending upon the precision of the sensor. Infrared is not visible to the human eyes but one can probably feel it sometimes as radiated heat when its intensity is high. A t ...
Recently we have been working on the STM-32 Nucleo 64 development board. Firstly, we tried to use it as our Flight Controller replacing our older Flight Controller that was purely Arduino based. There were various reasons for our inclination towards STM-32 Nucleo 64 over Arduino UNO. The main reasons included its higher flash memory(64 KB) compared to an Arduino Uno (32KB). Also, STM 32 uses a lot less power than most of the boards with these specifications which is an essential requirement for ...
If you’re following our previous posts, you might know that we are trying to implement Computer Vision in our Drone Inspection System. Although we have a model ready and trained, there is an issue with the credibility of the same. The model is trained on concrete crack images while we are trying to implement the model on pipe cracks. Both are different in a sense that cracks in pipes will be on a curved surface whereas the training set has all the images with cracks on flat surfaces. This ...
Greetings from the UAV R&D group. We hope all our fellow competitors are having a good time with the designing. Last month has been quite fulfilling for us as a research group. We were able to overcome some hurdles and complete the assembly of the drone. Also, there has been some progress in the sensor department. This post is all about it and also as you read through it, if some suggestion or doubt pops up in your head, feel free to comment.   The team has been working on identifying n ...
We are back with a second blog post and this one is pretty interesting. Since our UAV Inspection system uses Quadcopter(s) to collect data, we decided on making a custom one for ourselves to meet our specific requirements.   Quadcopters are infamous for having very low flight time, mainly because of the weight of the bunch of sensors, the battery and of course the frame. To increase the flight time we had to reduce the weight, but as we really can’t do anything about the motor weight ...
We are excited to be a part of this challenge, thank you element14 community to help us be a part of this. So as to introduce us and our plans, we wanted to share our proposal; as in what we plan to do. We are a team of students, from National Institute of Technology Warangal India, with the interest in drone technology; we aim to learn and contribute in this field. Below is our proposal:   Problem   Industrial inspection is a key aspect of any factory or production plant. In its curr ...
