Design
Cat GPT's defining feature is its pair of vertical spinner "ears" — two independent spinning discs positioned at the front of the robot that give it a recognizable silhouette while functioning as effective weapons. The robot's low profile chassis helps it absorb impacts and stay stable during matches.
The self-righting tail extends from the rear of the robot and can push Cat GPT back onto its wheels if flipped, a critical feature for a robot with vertical spinner weapons that can be vulnerable to being overturned.
