The bundle containing the ArduCopter 2.8 board lastly arrived from China, bearing the burden of our anticipation. I bear in mind choosing it up, the cardboard field weathered barely from its journey. As I tore by way of the layers of tape, it felt like unwrapping a long-awaited present. However as I lifted the ArduCopter 2.8 board out of the field, my coronary heart sank. The board, which was to be the cornerstone of our mission, regarded worn out and outdated, with seen scuffs and bent pins. This was simply considered one of a cascade of setbacks my group would face.
It began after I was assigned a mission in machine design at Obafemi Awolowo University (OAU), situated within the coronary heart of Ilé-Ifẹ̀, an historic Yoruba metropolis in Osun State, in southwest Nigeria, the place I’m a mechanical engineering pupil getting into my closing 12 months of a five-year program. OAU is considered one of Nigeria’s oldest and most prestigious universities, recognized for its stunning campus and structure. Some folks I do know confer with it because the “Stanford of Nigeria” due to the numerous variety of good startups it has spun off. Regardless of its popularity, although, OAU—like each different federally owned establishment in Nigeria—is underfunded and plagued by faculty strikes, resulting in interruptions in lecturers. The shortage of funding means college students should pay for his or her undergraduate initiatives themselves, making the success of any mission closely depending on the scholars’ monetary capabilities.
Dr. Oluwaseun K. Ajayi, an skilled in computer-aided design (CAD), machine design, and mechanisms, gave us the liberty to decide on our closing mission. I proposed a analysis mission based mostly on a paper titled “Advance Simulation Technique for Wheel-Terrain Interactions of Area Rovers: A Case Examine on the UAE Rashid Rover” by Ahmad Abubakar and coauthors. However because of the computational assets required, it was rejected. Dr. Ajayi as an alternative proposed that my fellow college students and I construct a surveillance drone, because it aligned together with his personal analysis. Dr. Ajayi, a passionate and pushed researcher, was motivated by the potential real-world functions of our mission. His fixed push for progress, whereas typically overwhelming, was rooted in his want to see us produce significant work.
As my group completed scoping out the preliminary ideas of the drone in CAD designs, we had been able to contribute cash towards implementing our concept. We carried out a value evaluation and determined to make use of a third-party vendor to assist us order our parts from China. We went this route because of delivery and customs points we’d beforehand skilled. Taking the third-party route was supposed to unravel the issue. Little did we suspect what was coming.
By the point we finalized our value evaluation and began to assemble funds, the value of the parts we wanted had skyrocketed because of a sudden financial disaster and depreciation of the Nigerian naira by 35 p.c in opposition to the U.S. greenback on the finish of January 2024. This was the genesis of our downside.
Initially, we had been a gaggle of 12, however because of the excessive value per particular person, Dr. Ajayi requested one other group, led by Tonbra Suoware, to merge with mine. Tonbra’s group had been planning a robotic arm project till Dr. Ajayi merged our groups and instructed us to work on the drone, with the intention of exhibiting it on the National Space Research and Development Agency, in Abuja, Nigeria. The merger elevated our group to 25 members, which helped with the person monetary burden but additionally meant that not everybody would actively take part within the mission. Many simply contributed their share of the cash.
Tonbra and I drove the mission ahead.
With Dr. Ajayi’s consent, my teammates and I scrapped the “surveillance” a part of the drone mission and raised the cash for creating simply the drone, totaling roughly 350,000 naira (roughly US $249). We needed to reduce down prices, which meant straying away from the unique specs of among the parts, just like the flight controller, battery, and power-distribution board. In any other case, the fee would have been far more insufferable.
We had been set to order the parts from China on 5 February 2024. Sadly, it was a protracted vacation in China, we had been advised, so we wouldn’t get the parts till March. This led to tense discussions with Dr. Ajayi, regardless of having briefed him concerning the state of affairs. Why the stress? Our faculty semester ends in March, and having parts arrive in March would imply that the mission can be lengthy overdue by the point we completed it. On the identical time, we college students had a obligatory academic-industrial coaching on the finish of the semester.

However what alternative did we now have? We couldn’t again down from the mission—that will have value us our grade.
We received most of our parts by mid-March, and instantly began engaged on the drone. We had the body 3D-printed at a value of fifty naira (roughly US $0.03) per gram for a 570-gram body, for a complete value of 28,500 naira (roughly US $18).
Subsequent, we turned to constructing the power-distribution system for {the electrical} parts. Initially, we’d deliberate to make use of a power-distribution board to evenly distribute energy from the battery to the pace controllers and the rotors. Nevertheless, the board we initially ordered was not accessible. Pressured to improvise, we used a Veroboard as an alternative. We linked the battery in a configuration parallel to the pace controllers to make sure that every rotor acquired equal energy. This improvisation did imply further prices, as we needed to hire soldering irons, hand drills, scorching glue, cables, a digital multimeter, and different instruments from an electronics hub in downtown Ilé-Ifẹ̀.
Every little thing was going easily till it was time to configure the flight controller—the ArduCopter 2.8 board—with the help of a software program program referred to as Mission Planner. We toiled day by day, combing by way of YouTube movies, on-line boards, Stack Trade, and different assets for steerage, all to no avail. We even downgraded the Mission Planner software program a few instances, solely to find that the board we’d waited for therefore patiently was out of date. It was actually heartbreaking, however we couldn’t order one other one as a result of we didn’t have time to attend for it to reach. Plus, getting one other flight controller would’ve value a further sum—240,000 naira (about US $150) for a Pixhawk 2.4.8 flight controller—which we didn’t have.
We knew our drone can be half-baked with out the flight controller. Nonetheless, given our semester-ending time constraint, we determined to proceed with the configuration of the transmitter and receiver. We made the ultimate connections and examined the parts with out the flight controller. To make sure that the transmitter might management all 4 rotors concurrently, we examined every rotor individually with every transmitter channel. The objective was to assign a single channel on the transmitter that will activate and synchronize all 4 rotors, permitting them to spin in unison throughout flight. This was essential, as a result of with out correct synchronization, the drone wouldn’t have the ability to keep a secure flight.

After the ultimate configuration and parts testing, we got down to take a look at our drone in its closing kind. However a couple of minutes into the testing, our battery failed. This failure meant the mission had failed, and we had been extremely disenchanted.
Once we lastly submitted our mission to Dr. Ajayi, the deadline had handed. He advised us to cost the battery so he might see the drone come alive, despite the fact that it couldn’t fly. However circumstances didn’t enable us to order a battery charger, and we had been at a loss as to the place to get assist with the flight controller and battery. There are not any tech hubs accessible for such issues in Ilé-Ifẹ̀. We advised Dr. Ajayi we couldn’t do as he’d requested and defined the state of affairs to him. He lastly allowed us to submit our work, and all group members acquired course credit score.
Resourcefulness will not be an alternative choice to funding
This expertise taught me invaluable classes about resilience, teamwork, and the tough realities of engineering initiatives carried out by college students in Nigeria. It confirmed me that whereas technical data is essential, the power to adapt and improvise when confronted with unexpected challenges is simply as essential. I additionally realized that failure, although disheartening, will not be an ending however a stepping stone towards progress and enchancment.
In my college, the calls for on mechanical engineering college students are exceptionally excessive. For example, in a single semester, I used to be typically assigned as much as 4 totally different main initiatives, every from a special professor. Alongside the drone mission, I labored on two different substantial initiatives for different programs. The fact is {that a} pupil’s capacity to attain properly in these initiatives is commonly closely depending on monetary assets. We’re consistently burdened with the prices of operating quite a few initiatives. The nation’s ongoing financial challenges, together with foreign money devaluation and inflation, solely exacerbate this burden.
In essence, when the world, together with graduate-school-admission committees and trade recruiters, evaluates transcripts from Nigerian engineering graduates, it’s essential to acknowledge {that a} grade might not absolutely replicate a pupil’s capabilities in a given course. They’ll additionally replicate monetary constraints, difficulties in sourcing tools and supplies, and the broader financial surroundings. This understanding should inform how transcripts are interpreted, as they inform a narrative not simply of educational efficiency but additionally of perseverance within the face of great challenges.
As I advance in my schooling, I plan to use these classes to future initiatives, understanding that perseverance and resourcefulness will probably be key to overcoming obstacles. The failed drone mission has additionally given me a practical glimpse into the working world, the place sudden setbacks and finances constraints are frequent. It has ready me to strategy my profession with each a sensible mindset and an understanding that success typically comes from how properly you handle difficulties, not simply how properly you execute plans.
