Fly, crash, fix, repeat. Flying at high speeds with a delicate drone designed to maximize performance can, and often results in complete fragmentation. I am constantly tinkering and improving my drone to fit my needs, often implementing cutting edge open-source solutions or scrappy repairs to get the job done.

I am extremely proud of my robot "Polarity" as it pushes the limits of what is technically possible in a 3lb robot to maximize size and destruction. In developing the robot, most "huge" style systems use a hollow shaft brush less motor or a belt drive system with a hollow shaft to drive the weapon between both halves of the robot. However, in the 3lb weight class, to achieve a dominant size, I had to think outside the box and apply my creative problem solving skills to spin the weapon. I ended up utilizing a dual motor direct drive system. Two counter rotating motors, one on each side of the system. Because of the counter rotating motors the two halves of the robot always face in the same direction while accelerating straight. You may be wondering how power and control is passed between the two halves. Rather than trying to build a strong enough hollow shaft motor to pass electronics through, I simply used two complete and independent electronic systems. Each side has its own battery, drive motor, ESCs and receiver. Through clever binding with my radio I am able to simultaneously control both halves of the robot as one.

My favorite technique yet-to-be mastered by the masses is optically clear resin printing. Using a highly calibrated photo-polymerization resin printer in my DIY environment control chamber allows me to print clear objects that can be colored later by alcohol inks or RGB lights to create this glassy effect.
