Our team, Foxtrot, integrated sustainability into the design and construction of our micro-mouse robot, focusing on both the physical build and the overarching design principles. Central to our approach was the use of a printed circuit board (PCB) which was designed with environmental considerations in mind.

During the assembly of the micro-mouse robot, we implemented practices aimed at minimizing waste. This includes precise calculation and efficient usage of materials to avoid excess, and recycling scrap materials wherever possible. Any unutilized components were correctly recycled so they could be reutilized in the future.

The robot was designed to be easily disassembled as most of the components besides the Raspberry Pi Pico, are screwed instead of soldered, being practical to remove certain components that are not functioning for example. This allows for better recycling practices and the possibility of part reuse in other projects or repairs, thereby extending the materials’ life cycle and reducing electronic waste.

Our team as well is also dedicated to implementing a comprehensive recycling plan for our micro-mouse project’s electronic components at their end of life. This plan is designed to ensure environmental responsibility and align with sustainable best practices, following these key strategies:

 At the project’s conclusion, each component of the micromouse will be carefully evaluated to determine its potential for reuse, repurposing, or recycling. Functional parts such as sensors and motors will be earmarked for use in future projects, reducing the need for new resources.

 The micromouse will be methodically disassembled to ensure that all materials, especially those that are hazardous, are handled safely and according to environmental regulations. This step minimizes the risk of contamination and facilitates more efficient recycling processes.

Components will be sorted into categories—metals, plastics, and electronics. We will partner with certified e-waste recyclers to process these materials, focusing on facilities that comply with local and international standards to ensure high recovery rates and minimal environmental impact.

Items like batteries and certain capacitors will be processed separately under strict guidelines to prevent environmental harm.

 Throughout the recycling process, we will maintain detailed records of how materials are handled and disposed of. This documentation will help us comply with regulatory requirements and enhance our project’s transparency.

As a student member of the Institution of Engineering and Technology (IET) and a future professional engineer, I am committed to upholding the ethical standards and principles as outlined by the Royal Academy of Engineering (RAEng) and the Engineering Council (EC). Reflecting on these principles and the guidance provided by the IET, as I recognize the critical role that ethics plays in shaping a responsible engineering practice.

I understand the importance of acting with integrity and being transparent in all my undertakings. This includes being honest about my capabilities and the results of my work, acknowledging my mistakes, and striving for fairness in my interactions. I am committed to developing these traits further, as they are essential in building trust and credibility in my professional relationships and outputs.

I recognize the importance of maintaining rigor in my academic and future professional work. This entails continually updating my knowledge base, adhering to the best technical standards, and approaching problem-solving with precision. My commitment extends to fostering an environment where facts and evidence are respected and where alternative views are considered and valued.

As I grow in my career, I aim to embrace leadership roles that enable me to advocate for ethical practices and effective communication within the engineering community. This includes promoting inclusivity, engaging with societal concerns, and helping the public understand the benefits and implications of engineering work.

To support my ongoing learning and application of these principles, I frequently consult resources that deepen my understanding of engineering ethics. One particularly valuable resource is the Online Ethics Center for Engineering and Science (https://onlineethics.org/) at the National Academy of Engineering. This site provides case studies, educational tools, and research materials regarding the understanding of ethical dimensions of engineering practice. I chose this resource because it offers practical insights and real-world applications of ethical principles, making it an excellent tool for both students and professionals aiming to navigate complex ethical dilemmas in engineering.
