Aerial Bots in Humanitarian Logistics: Lessons from the COVID-19 Crisis and Future Applications

 The COVID-19 pandemic not only exposed vulnerabilities in global healthcare systems but also challenged conventional supply chain operations. This blog post aims to explore the academic insights from the study by Koshta, Devi, and Patra (2021), which investigates the role of drone technology—referred to as "aerial bots"—in bolstering supply chain performance during a pandemic.

The article offers a conceptual and empirical exploration of how drones supported food, healthcare, and administrative supply chains when physical mobility was severely restricted. Our goal is to analyze how this technology responded to an unprecedented crisis, its advantages, limitations, and what it implies for future disaster-resilient logistics infrastructure.



Drones as a Disruptive Force in Pandemic Response

The outbreak of COVID-19 catalyzed a surge in the adoption of drones across several sectors due to their unique capabilities: contactless delivery, aerial surveillance, and the ability to bypass road infrastructure. Historically utilized in military and security contexts (Hassanalian & Abdelkefi, 2017), drones have since evolved into essential tools for logistics and public health, especially under the extraordinary conditions created by the pandemic.

During national lockdowns, drones provided rapid transportation of medical supplies, lab samples, and food to inaccessible or quarantined areas. In countries like Ghana and Rwanda, drone operators like Zipline dramatically reduced diagnostic sample delivery times—from several hours to under 30 minutes—facilitating quicker COVID-19 testing and treatment responses (Baker, 2020; Ayamga et al., 2021).

Applications Across Three Supply Chains

1. Healthcare Supply Chain

One of the most pressing challenges was timely diagnosis. The shortage of testing centers meant samples needed to travel long distances. Aerial bots filled this gap by ensuring timely sample transportation, particularly in regions with poor road infrastructure. Moreover, drones were used for last-mile delivery of personal protective equipment (PPE) and essential drugs, thus minimizing exposure risk for frontline health workers. In countries like India and China, where infections among healthcare personnel surged, drones also helped disinfect PPE and reduce human contact during disposal processes (Koshta et al., 2021).

2. Food Supply Chain

With supermarket closures and movement restrictions, aerial bots emerged as a viable last-mile delivery solution. Inspired by models used by Amazon and Walgreens for commercial drone deliveries (Etherington, 2019), the technology was repurposed for humanitarian logistics. The benefits included faster delivery, environmental sustainability, and enhanced safety during lockdowns. Especially in rural or high-density urban areas, drone-enabled logistics ensured continued access to food and groceries, mitigating the risk of nutritional deficiencies and supply chain collapse (Pate & van Nieuwkoop, 2020).

3. Administrative Functions

Drones also played a role in enforcing lockdown measures. Fitted with cameras and speakers, they assisted law enforcement agencies with surveillance, public announcements, and thermal imaging to detect unauthorized gatherings. This was particularly useful in overburdened or under-resourced jurisdictions, enhancing compliance and reducing the burden on human police forces (Koshta et al., 2021).

Strategic and Research Implications

While drones offered substantial benefits, the authors acknowledge barriers such as cost, regulatory limitations, and technological maturity. Future research should focus on:

  • Optimizing drone logistics using mathematical modeling (e.g., facility location models for PPE distribution).

  • Integrating drones into hospital infrastructure for in-building monitoring and delivery.

  • Developing inclusive business models that allow small businesses and clinics to access drone services.

  • Surveillance optimization to determine drone quantity and patrol areas for maximum effectiveness (Moshref-Javadi & Winkenbach, 2021).

These recommendations align with calls for digital transformation in disaster logistics and pandemic preparedness from organizations such as the World Health Organization (WHO, 2020) and World Bank.

Conclusion

The use of aerial bots in humanitarian supply chains during COVID-19 has demonstrated the technology’s versatility and value. As the pandemic recedes, it is imperative to institutionalize such technologies into national disaster response strategies. This would not only enhance resilience but also democratize access to healthcare and essentials during future crises. The integration of drone logistics is no longer futuristic—it is a pragmatic necessity for agile, safe, and efficient supply chains.

FastPlan: Accelerating Drone-Centric Search Operations for Post-Disaster Relief

Image
  In the wake of increasingly severe natural and man-made disasters, rapid response is critical. Traditional rescue operations often face delays due to limited manpower, inaccessible areas, and communication breakdowns. Unmanned aerial vehicles (UAVs), commonly known as drones, have emerged as a promising supplement for search and rescue missions. However, operational challenges—especially for non-professional pilots—persist.
