In the world of aeronautical engineering, innovation and practical application often go hand in hand. For me while serving in the British Army, the path to gaining expertise in electronics led to an extraordinary final consolidation project—an EOD (Explosive Ordnance Disposal) robot. This robot not only showcased skills in avionics but also involved problem-solving, creativity, and the ability to adapt to changing circumstances. In this post, we delve into the journey of designing and building an EOD robot as part of a level 3 extended diploma in aeronautical engineering.
The EOD robot project was part of a comprehensive avionics training course. This course provided the foundation for the design, development, and execution of this exceptional project. The project encompassed a wide range of skills, including digital and analog electronics theory, problem-solving, coding, and manufacturing, making it an intensive and rewarding endeavor.
Challenges and Innovations
Creating an EOD robot from scratch was no small feat. One of the initial challenges was to automate the robot and implement remote control via Wi-Fi and the Internet of Things (IoT). However, due to the stringent WAN security protocols within the military establishment, this proved unachievable. Instead, the project transitioned to a local area connection, requiring users to be on the same network to operate the robot effectively.
A simple Android application was developed for controlling the robot’s forward and reverse movements, as well as operating the grabbing arm. This adaptation allowed for local control and met the project’s objectives, highlighting the adaptability of the design.
Design and Components
The EOD robot’s design involved repurposing various components. The back wheels were sourced from an old office chair, while the front driving wheels consisted of simple motors that operated independently to facilitate near-neutral turns. The robot arm, originally a toy, required significant integration efforts. The challenge involved converting the arm’s simple controller, which operated via variable resistors, into a digital I/O system for remote operation.
A Unique Feature: Remote Viewing
One of the project’s most exciting features was the incorporation of a CMOS camera mounted on top of the arm, behind the claw. This camera was connected to an RF transmitter, enabling operators to view the robot’s perspective on an old CRT TV via a SCART connection. While controlling the robot was a bit challenging, this feature added a dimension of remote visibility and control that was both impressive and practical.
Fluid Design and Adaptive Problem-Solving
The design of the EOD robot was anything but rigid. It involved experimenting with different ideas and knowing when to pivot when challenges arose. In a project with tight time constraints, the ability to adapt and evolve the design was crucial to success.
A Presentation to Remember
The EOD robot was not just a project; it was a demonstration of ingenuity, skill, and adaptability. The only time it was used was during the final presentation, where it was showcased to a group of soldiers and officers. Its uniqueness and capability attracted significant interest, demonstrating the importance of innovation and practical application in the field of avionics and aeronautical engineering.
The journey of building an EOD robot during avionics training in the British Army showcases the depth of skills, creativity, and adaptability required in the field of aeronautical engineering. Despite the challenges faced during the project, it served as a testament to the ability to pivot, adapt, and deliver impressive results within limited timeframes.
This project is not just about building a robot; it’s about demonstrating the fusion of avionics knowledge, problem-solving skills, and innovation in a real-world context. It’s a testament to the dedication and expertise developed during avionics training in the military.
With this post, we’ve delved into the incredible journey of designing, building, and demonstrating an EOD robot—a project that represents the essence of aeronautical engineering and innovation in the British Army.
