Featherweight

Featherweight category

The Featherweight category is one of the most popular and long-established classes. Its limit is traditionally 13.6 kg (30 pounds). At this weight, robots can already carry truly devastating weapons while still being portable and relatively affordable – making it a frequent choice for builders who want to construct “full-scale” combat robots.

Characteristics:

• Weight limit: 13.6 kg (30 pounds).

• Dimensions: Not strictly limited, but the robot must fit into the starting zone and be able to enter the arena safely.

• Electronics and motors: Powerful geared DC motors or brushless setups; batteries are typically LiPo 6s and above. Motors and ESCs must be rated for significant current spikes.

Featherweight is a category where the fighting gets “real” – featuring immense kinetic weapon energy, flying debris, and heavy impacts.

This weight category is very popular among experienced builders. Robots in this class appear very professional, whether in terms of size, structural design possibilities, or destructive power. Featherweight matches are often as exciting as those in televised competitions – loud, intense, and with real destructive impact. Robots of this weight are generally less focused on pure weaponry than smaller robots, shifting more toward reliability and defensive armor. They no longer use motors meant for small drones; Featherweight robots operate on a larger scale with motors typically found in large RC cars and electric skateboards. Because of this, the category is more financially demanding than lower weight classes, partly because many parts are CNC machined. Featherweight is ideal for those who want to transition their experience from smaller categories into the world of serious engineering and professional robotics.

The Featherweight (13.6 kg) category is often considered the gold standard of amateur robotic competitions: the machines are powerful enough to make their battles dramatic and exciting, yet they are still relatively affordable and compact compared to higher weight classes (Heavyweight, 110 kg+).
