The scope and complexity of a drone project can seem quite daunting at first. Drones incorporate elements of mechanical engineering, electrical engineering, computer science, and aviation. Students will have to learn about and implement systems related to aerodynamics, flight controls, propulsion, power, communications, sensors, programming, etc. This requires learning new technical skills and coordinating efforts across different areas. To manage this, it’s important for students to thoroughly research and plan their project before starting any physical work. Breaking the project into clear phases and milestones will help track progress. Working with an advisor experienced in drone design can provide valuable guidance.

Another major challenge is ensuring the drone design and components selected are able to achieve the project goals. For example, selecting motors, propellers, battery, flight controller etc. that have the necessary performance characteristics needed for a long-range or high-payload mission. To address this, extensive simulations and calculations should be done upfront to inform hardware choices. Open-source drone design and simulation software can help validate design decisions without requiring physical prototyping. Iterative testing and refining of the prototype is also important to refine performance.

Securing funding for parts, materials, and tools necessary to build and test a drone can pose difficulties. Drones require a variety of expensive components like multicopter frames, electrical speed controllers, cameras, sensors, batteries etc. Lack of access to proper workshop facilities and equipment for manufacturing and assembly tasks can also hinder progress. To overcome this challenge, students should carefully budget project costs, apply for internal university grants or crowdfunding, and leverage any discounts available to students. Partnering with local drone community groups or companies may provide donated or discounted components.

Drone electronics and software can exhibit unexpected bugs and stability issues during testing that require debug and fixes. Factors like vibration, weight distribution shifts during flights, electrical and RF noise interference etc. may lead to reliability problems. Debugging crashed drones in the field is also difficult. Careful mechanical design, redundant systems, thorough bench testing, and use of simulation tools can eliminate many issues beforehand. But students must allow time for iterative debugging as fixing bugs uncovered in flight tests takes time and persistence. Proper documentation of troubleshooting steps is important.

Another challenge lies in navigating relevant government regulations for drone operation and ensuring compliance. Regulations related to drone size, weight, permitted airspace, pilot certifications, privacy, payloads etc. differ based on location. Non-compliance could result in legal penalties. Students need guidance on regulations applicable to their university location. Flight testing should only be done with proper permissions and safety procedures followed. Sufficient liability insurance may also be required which adds to costs.

Project scheduling and group coordination difficulties may arise as drone projects involve contributions from multi-disciplinary domains. Staying on schedule is challenging as unexpected issues will disrupt timelines. Proper communication between group members, setting intermediate deadlines, assigning clearly defined roles, documenting progress, and regular status updates with advisors help manage coordination difficulties and minimize delays. Using project management software tools can facilitate collaboration.

Some of the key challenges students may face include complexity of drone technologies, design validation, funding constraints, reliability issues during testing, regulatory compliance, and coordination within multi-disciplinary teams. With thorough upfront planning, breaking tasks into phases, frequent testing using simulation tools, crowd-sourcing resources, clear documentation, and continuous communication among group members – students can successfully overcome these challenges to complete an impactful drone capstone project. Taking guidance from experienced mentors is also crucial. With perseverance and teamwork, students can gain immense technical skills and satisfaction from seeing their custom-designed drone take to the skies.
