Helix is an antweight ring spinner combat robot that uses its large weapon to protect itself from its opponents, instead of using normal armor.
- 10" asymmetric AR500 steel weapon spinning at over 260 MPH with 128 joules of energy!
- Vertical element to the weapon's counterweight blocks attacks from horizontal spinners before they hit the robot itself.
- Dual RS2205 Brushless Weapon Motors
- Tangent drive with tank treads.
- Carbon fiber frame
- Durable TPU body with ultra lightweight design.
- Custom PCB that serves as a switch, series board for the batteries, and a BEC for the receiver.
Combat robotics has been one of my main hobbies ever since I joined my school's combat robotics team at the beginning fot he 2023-2024 school year. Throughout that time, I have mainly spent my time building 15lb eggbeater combat robots, where, due to the time and money invested into them, we are often scared to go too far outside of the box since a small design flaw could mean thousands of dollars and hundreds of hours were wasted. Highway is the perfect opportunity to make something outside of the box, as complex and creative projects are rewarded.
