Over the last few years, the engineers at the company have invested both their time and sleepless nights in formulating a process for the development of Machine learning algorithms that will satisfy real-time constraints with minimal RAM usage. This is quite a tall task as per default, that would force one to do their development directly in C language. Although that seems like the right choice, the downside is the direct correlation of the debugging time with algorithm complexity.  Such a time could have been rather used in optimizing the algorithm within the MATLAB environment which has excellent tools for the analysis, plotting and debugging. So it was decided to rather learn the Code generation process with the hope that future algorithm could be designed in a similar fashion without the hassle of the compiler-specific run-time issues. The development of this machine learning algorithm would eventually be implemented in a 32bit, 160Mhz speed, 260KB RAM microcontroll...

Over the past two years, the research and development team has been developing a method to identify faulty motors on a drone without interrupting a mission (automated or manual). This is of high interest as it will give the pilot more information to ensure the successful recovery of the system in the event of a fault. The team of engineers has developed a Machine learning (using Artificial Neural Networks) framework that superimposes the dynamics on the controls in order to detect and locate a fault in a rotor without compromising the mission. The graph above shows simulate a rotor fault once the drone reaches 9 m/s and the fault identification system (FIS) detects a fault 1-second later. Once the other rotors are analyzed, the Rotor1 is identified as having a fault and this information is sent back to the pilot. It's important to know that even though a major fault has occurred, the drone a capable of flying for some time until instability grows and the drone becomes unc...

The race towards bringing robotic flying things hasn't slowed down. The effort to reduce the art of electronics and power consumption to a minimal size has often not shown the commercial uptake it deserves. At least from the skills-basis standpoint. It takes a pretty special bunch of individuals to be able to work in a world of the minuscule. The question I guess is more from the intent of the technology. Do you remember the Kodak camera that you could find at any tourist store? At the time, it was brilliant technology with a commercial uptake, but not sustainable for the needs of the future tourist. That technology had to die and die hard. On the other hand, there's aluminium/cast iron pot in the dusty streets of some West African countries, is still made in the same way 30+ years after that technology was conceived. So what makes technology have a staying factor? In the case of microrobots and any new technologies that are on the horizon (like our interest i...

The impact (good and bad) of drones in society is no longer in question. But what will it take for drones to impact a traditionally outdated, low-profit-margin civil works industry through the use of technology? The solution lies in a low-cost approach. One could say it all started when a bunch of scientists realized they could do a far better job in measuring objects accurately and at a distance rather then an individual putting himself in harm's way and using expensive/primitive equipment for the same task. We're talking about photogrammetry. In a nutshell (or should I say according to Wikipedia), Photogrammetry is the science of making measurements from photographs, especially for recovering the exact positions of surface points. In more simplistic terms, provided you have some form of frame of reference (like a ruler) you can determine the physical properties of objects and their exact location to the accuracy of the remote sensing equipment used (a 4K-size imag...

There's a lot of debate around the economic suitability of drones for the delivery of the goods as a direct competitor to traditional trucks and delivery vans. There's an article written by Flexport which highlights two crucial factors that makes drones delivery of general goods not feasible, even in the near future: (1) route density and (2) drop size. Route density is the number of drop-offs you can make on a delivery route and drop-size is the number of parcels per stop on that delivery route. Given the strict airspace regulations on drone size and weight, it has become quite evident, particularly in the African context, that the delivery of general goods will not be an economically viable option even though the obvious need might say otherwise.  However, further analysis and demonstration have shown, from companies like Matternet and others, that the transport of the time-sensitive and high-value parcels (legal-documents, medicine samples, high-value spices...

We've reviewed a document on the impact of the blue-green algae on the irrigation of the agricultural farmlands.  Our investigations follows the trend of the bursts of blue-green algae is the dams using for livestock and plants which has caused many illnesses to the farm workers and their families specifically in small-holding agricultural areas. So we've decided to undergo experimental research into the application of a low-cost drone solution for the analysis, prediction and the eventual eradication of the blue-green algae in dams which has a direct impact in the production yield of the both animals and plants. This research will comprise of the development of the remote sensing system which will generate data that will be used as inputs into a predictive model which will be used to help farmers make alternative plans well-before the blue-green algae has a financial impact the farms' operations and the safety of its workers. The proposal with be prese...

We've reviewed a report by Deloitte discussing issues on how to leverage and protect Africa's innovation for future growth and economic stability. It was highlighted that the traditional focus on exploiting commodities hasn't yielded the redistribution of wealth or improve the standard of living for those working in that sector. Moreover, over 75% of economic activities happen in the informal sector (Nigeria statistics), which is exposed to the volatility that commodity markets are subjected to, which is detrimental to the impoverished communities. One of the major points which directly relates to our mission objective is the following quote from the report: " Yet, as much as innovation is important, there needs to be more focus on the final outcome of innovative solutions. "  In Africa, innovation is part of the daily survival. But it's usually unstructured, very often short-sighted and localized in it's application. Moreover, the growing yout...

As a student completing my final year, I vividly remember the insatiable desire to just complete the degree, graduate and kiss university life goodbye! Even though I actually enjoyed my course and the fact this had been my dream since my second year of high school, I felt I had enough. At that point, the thought of pursuing a postgraduate degree was the further thing from my mind. Such psychological damage was based on the opinions (albeit biased) that academics, the professors and full-time researchers that taught us, seemed detached from reality and their expectations from the feeble and vulnerable students, were beyond unreasonable. I vividly remember the insatiable desire to just complete my course, graduate and kiss university life goodbye! Even though I saw myself pursuing a postgraduate degree, the notion of having to face the same ordeal of my last few months as an undergraduate, was enough to convince me otherwise. I just didn't see myself having to deal with t...

The objective for this milestone was to integrate the same model functionality developed and analyzed within the Matlab/Simulink environment into a mature environment that will be able to test most functionalities of the Flight controller software that will be flashed for real-flight testing. The decision was to either migrate the Ardupilot (in this case ArduCopter ) software into the Matlab environment or integrate the highly nonlinear quadcopter model with flapping dynamics into the Ardupilot environment. The former option would mean no easy integration with Mission Planner and the real-time sofware-in-the-loop ( SITL ) testing tool (which also includes the infrastructure to communicate with the Flightgear 3D visualization environemt, while the later with make use of singular environment although the software development effort would quite tedious and error-prone. It was chosen to go with the first option as this was thought to be lead to more mature verification method prior...
