Gear Ratio Calculator

We have developed an interactive physics simulation that calculates the optimal gear reduction to minimize travel time of given distances. This calculator accounts for motor torque curves, robot mass, rotational inertia, friction, battery characteristics, among other factors. It outputs an easily readable graph demonstrating the trade-off between gear reduction and travel time for several distances. The calculator is accessible on github for the source code, and through MyBinder for an in-browser interface. It was created using python in Jupyter Notebook.

Laptop refurbishing

We are accepting laptops to refurbish them. The laptops we are able to refurbish we donate to schools in Haiti, the Dominican Republic, and India with an array of educational materials. Any left overs will be donated to underserved schools in our community. For nonworking laptops, we will repurpose the laptop batteries into usable USB chargers. To learn more about this program, click here.

Starting a new FIRST LEGO League (FLL)

We summarized some of our know-how in a FLL primer. To learn more about starting a team, click here.

PRINT Swerve for FTC

FTC Robocracy is proud to release our very own, competition tested swerve drive model to the public. It is designed to be made out of only 3d printed and COTS components, with no CNC machinery required.

We provide here, everything you need to make your very own PRINT Swerve. This innovative swerve drive is entirely build out of 3D printed parts, and other COTS components. It uses high quality gears for unprecedented reliability. We use a novel “Tower” design where the drive motor is directly mounted on top of the drive to deliver the compact footprint needed for FTC robots. To our knowledge, this is the first 3D printable, nearly-indestructible integrated swerve drive, optimized for FTC use.
