SKELD // Combat Robotics Project

About the Team

SKELD is being developed by a team of three students from Berry College's Creative Technologies program: Gio, J.T., and Asiel. We first met through HackBerry Lab, Berry College's campus MakerSpace, where students collaborate on engineering, fabrication, design, and technology projects. Through countless projects and late nights at HackBerry, we became close friends who share a passion for building cool projects and solving problems.

Our team combines a variety of skills and experiences that contribute to the development of SKELD.

Gio – Fabrication Lead

Gio oversees the fabrication and physical construction of SKELD. He has extensive experience creating prototypes and mockups using foamcore and other rapid prototyping methods, which is very helpful when working in a prototyping environment. His work allows the team to quickly evaluate concepts in a tangible way before investing time and resources into final fabricating.

J.T. – Electronics Lead

J.T. manages the robot's electrical systems and electronics integration. With previous experience designing custom printed circuit boards and working with electronic systems, he is responsible for ensuring that SKELD's drive systems, power systems, and weapon systems operate reliably, and safely, throughout competition.

Asiel - CAD & Design Lead

Asiel is responsible for the robot's design and CAD development using Fusion 360. Every major component of SKELD begins as a digital model before moving into prototyping and fabrication. Asiel has extensive experience with Fusion 360 and has previously created highly detailed projects, including a full scale digital model of Boston Dynamics' SPOT robot dog. Throughout the development of SKELD, he has focused on optimizing weight distribution, component placement, and overall robot architecture.

Although each team member has specific responsibilities, every aspect of SKELD is developed collaboratively. We believe strongly in the philosophy taught throughout the Creative Technologies program: Fail Fast, Fail Often, Fail Forward. Every prototype, test, and design revision provides valuable lessons that help improve the robot and strengthen our engineering process.

About Combat Robotics at Berry College

SKELD is being developed as part of the Combat Robotics summer course offered through Berry College's Creative Technologies department.

The course introduces students to the principles of combat robotics through the design, construction, testing, and operation of remotely controlled robots built specifically for competitive combat. Students gain experience with mechanical design, fabrication, electronics, problem solving, prototyping, and strategic decision making while working toward a final competitive event.

At the conclusion of the course, eight student teams will compete in the HackBerry Combat Robotics Tournament. The event is open to the public and will be promoted and streamed through HackBerry Lab's media platforms, allowing members of the Berry College community and the broader public to follow the competition.

This tournament is following the 3lb class under the NHRL(National Havoc Robotics League) regulations.

This is only the second year the course has been offered, making it an exciting opportunity to help establish a growing tradition of engineering-focused competition and innovation at Berry College.

Each team in the tournament was assigned a color, and SKELD's color is pink. We plan on leaning towards this for our logo, and robot cosmetics.

What is SKELD?

The robot's design is heavily inspired by The Skeld, the iconic map from the game Among Us.

Among Us has become something of a tradition within the HackBerry Lab community. We often organize games as a way to build friendships and strengthen the MakerSpace community. Because of the impact the game has had on our group, we wanted to create a robot that reflected that fun, shared experience while still being a serious engineering project.

The result is SKELD: a combat robot that combines engineering, competition, and a bit of community culture into a single design.

CAD Modeling

Every component of SKELD begins as a digital model created in Fusion 360. Before any physical prototypes are built, the robot is developed virtually, allowing us to explore ideas, test layouts, and refine designs efficiently throughout the development process.

Fusion 360 also serves as the central hub for the entire project. The CAD model allows us to verify dimensions, ensure compliance with the competition's 3lb weight class regulations, and confirm that all components fit together properly before fabrication begins. By assembling the robot digitally, potential issues can be identified and resolved early in the design process.

In addition to guiding manufacturing, the CAD model acts as a communication tool for the team. Design concepts, modifications, and future improvements can be easily shared, discussed, and evaluated before moving into prototyping and construction.

As development continues, Fusion 360 remains one of the most important tools in the creation of SKELD, providing the foundation upon which every stage of the project is built.

Weapon System Development

Early in development, SKELD was designed around a drum spinner weapon system.

While drum spinners can be highly effective, our team recognized that manufacturing a reliable drum with our available fabrication methods would introduce unnecessary complexity and various additional points of failure. Rather than forcing a design that would be difficult to manufacture reliably, we applied our iterative design philosophy and reevaluated our approach.

The problem was having a very long drum, so we shortened its horizontal length. This transitioned us into using a vertical spinner weapon system utilizing a 3mm steel weapon and 3D printed assembly. The final weapon significantly improves manufacturability, reliability, and overall project feasibility.

One of the first things you may notice about SKELD's current weapon is that it is intentionally asymmetrical. The striking side of the weapon(which resembles a hammer) extends farther from the center of rotation than the counterweight side, allowing more force to be concentrated at the point of impact. This design choice increases the amount of kinetic energy delivered to an opponent during a hit while still maintaining balance throughout operation. Rather than relying on sharp edges or cutting attacks, our weapon is designed as a kinetic effector focused on delivering powerful blunt-force impacts.

Because combat robots often make contact for only a fraction of a second, we wanted to maximize the effectiveness of every hit. By concentrating the weapon's mass on the hammer side, the majority of the stored rotational energy is transferred through a single impact point, increasing the robot's ability to destabilize and launch opponents.

To complement the weapon system, SKELD also features a set of front forks. These forks are designed to get underneath opposing robots and lift one side slightly off the arena floor before weapon contact occurs. By disrupting the opponent's stability and reducing the amount of traction they have with the ground, the forks create a more favorable angle for impact. When combined with the vertical spinner, this strategy increases the likelihood of lifting, flipping, or launching opponents into the air rather than simply pushing them away.

This decision reflects an important engineering principle: successful designs are not necessarily the most ambitious, but rather the designs that can be built, tested, and improved effectively.

Prototyping and Testing

Rapid prototyping has been a critical part of SKELD's development.

The team has already produced a full foamcore prototype that allowed us to evaluate dimensions, internal layout, and drivability before committing to final manufacturing. The prototype successfully demonstrated the overall design concept and verified that the robot's drive system performs as expected.

By building physical prototypes early, we can identify potential issues before investing significant resources into final parts.

This iterative workflow allows our team to move quickly, test frequently, and continuously improve the robot throughout development.

Manufacturing

The majority of SKELD's structural components are manufactured through 3D printing.

The robot will utilize PLA printed components alongside a steel weapon assembly, electronic systems, and foam wheels. While these materials allow us to build and test the robot within our current budget/constraints, access to higher quality manufacturing options and materials would significantly improve the robot's performance and durability.

Additional resources would allow us to explore stronger materials, higher quality components, improved drivetrain solutions, and more advanced manufacturing methods that could increase the robot's competitiveness both at Berry College and potentially in future NHRL competitions.

Looking Toward Competition

Our immediate goal is to successfully compete in the HackBerry Combat Robotics Tournament and demonstrate the results of an entire summer of engineering development.

Long-term, we would love to continue refining SKELD beyond the classroom and potentially compete in official NHRL events in the future if resources and opportunities permit.

Regardless of competitive outcomes, the project serves as a valuable educational experience that develops practical engineering skills while encouraging creativity, teamwork, and problem-solving. We believe engineering projects should be more than just functional; they should be engaging, rewarding, and personally meaningful to the people who create them. SKELD reflects that philosophy by combining technical design with a unique identity inspired by our community, demonstrating that great engineering can be both effective and fun.

Support

As students, we operate under significant budget constraints while attempting to build a competitive combat robot.

Support from PCBWay would directly contribute toward stronger materials, improved manufacturing capabilities, higher quality drivetrain components, upgraded wheels, and additional prototyping resources. Access to manufacturing services/materials would allow us to iterate more effectively and produce components that would otherwise be difficult for a student team to obtain.

Beyond the robot itself, PCBWay's support would help demonstrate how industry partnerships can empower student innovation. Projects like SKELD exist because students are given opportunities to experiment, fail, learn, and create. Sponsorships from companies like PCBWay help transform ambitious ideas into real engineering projects while inspiring future generations of makers and engineers to pursue their own designs.

Thank you for considering our application and supporting student innovation through hands-on engineering and combat robotics.
