Lead Engineer Patrick Faulkner and FightFest Director Ed Hodges are overseeing the development of new combat robotics at the Accu facility to prepare for the upcoming high-energy tournament at Smart Manufacturing Week. The collaborative effort between Accu and the FightFest organisers aims to highlight the precision engineering and hardware durability required to survive the competitive arena while providing a platform for technical innovation.
Building a formidable machine for these events involves navigating a complex landscape of weight restrictions, material science, and electronic reliability. The process starts long before the metal is cut, often beginning in Computer-Aided Design (CAD) environments where engineers must balance the destructive power of a weapon system against the protective requirements of the robot’s chassis.
Success in this field relies heavily on industrial-grade components that can withstand extreme G-forces and blunt impact. Many of the participants are professional engineers who apply the same rigor to these machines as they would to high-end industrial machinery, focusing on everything from motor torque to the shear strength of fasteners.
Weight classes and the cost of entry for building fighting robots
Combat robotics exists across a broad spectrum of weight classes, ranging from the 75-gram fleaweights to the massive heavyweights that tip the scales at 340 pounds. For many beginners, the 1-pound Antweight class serves as an entry point into the discipline, allowing builders to experiment with design iteration without the financial burden of larger machines.
The cost of building a fighting robot varies wildly depending on the ambition and scale of the project. While an Antweight kit can be assembled for roughly $166, more advanced DIY builds in that same weight class often exceed several hundred dollars once high-end transmitters and chargers are factored in. This accessibility at the lower levels contrasts sharply with the top-tier competitions.
At the Heavyweight level (220 lbs), a competitive machine typically requires an initial investment of between $4,000 and $5,000. However, elite teams in tournaments like BattleBots often spend upwards of $25,000 to remain competitive. For instance, the renowned robot Bite Force reportedly cost $30,000 to construct, illustrating the significant capital required to reach the pinnacle of the sport.
Engineering challenges in high-impact robot design
Patrick Faulkner and the team at Accu emphasize that there is no such thing as a “perfect design” in combat robotics. Builders must constantly innovate to counter opponents who might bring more powerful motors or superior armour plating to the arena. This evolution is often driven by African IoT sector growth and industrial connectivity trends that emphasize smarter, more resilient hardware.
The engineering discipline required for a formidable robot includes:
- Structural Integrity: Using materials like AR500 steel or aerospace-grade titanium for armour to resist spinning blades and hammers.
- Drive Systems: Implementing high-torque brushless motors that allow for rapid acceleration and precise positioning during a bout.
- Weaponry: Balancing the kinetic energy of spinners, the leverage of flippers, or the crushing force of hydraulic grapplers.
- Electronics: Protecting speed controllers and batteries from the shock and vibration of combat.
Designers must also consider the “man-hours” involved, which are rarely captured in the raw material costs. A robot like Mammoth, despite a material cost of approximately $8,000, required hundreds of hours of labour to assemble and tune. This dedication to craftsmanship is a hallmark of the engineers appearing at Smart Manufacturing Week.
Integration of industrial technology and safety protocols
While the focus is often on the spectacular destruction that occurs in the arena, the underlying technology is deeply connected to broader industrial trends. The precision required for these builds mirrors the standards seen where industrial and engineering stocks rally due to innovations in manufacturing and automation. In many cases, fighting robots serve as a testing ground for extreme durability in electronics.
Safety remains the most critical aspect of the build process. Combat robotics is inherently dangerous, and organisers like Ed Hodges enforce strict protocols to ensure that high-speed weapons and lithium-polymer batteries do not pose a risk to spectators or builders. All testing must be conducted within reinforced enclosures by qualified professionals.
For those looking to enter the field, the community recommends starting small and focusing on education. By mastering the basics of CAD, physics, and electronics in the Antweight or Beetleweight classes, builders can develop the skills necessary to eventually tackle the high-stakes engineering of the Heavyweight division.
The upcoming FightFest tournament at Smart Manufacturing Week will showcase these principles in action, providing a rare look at how Patrick Faulkner and other leading engineers push the boundaries of what remote-controlled machinery can achieve. As industrial technology continues to advance, the lessons learned in the box will likely find their way back into the factories and laboratories that power global production.
