Quadrotor is a semi-autonomous and radio-operated aerial vehicle designed for completing a wide range of tasks using multiple, interchangeable hardware modules. The quadrotor helicopter, or quadrotor for short, is an especially fast and maneuverable aerial platform. Our wide body quadrotor is designed to be both durable and powerful, so it can perform a variety of tasks such as object following, collision avoidance, 3d mapping, and altitude control. It does through hardware modularity, allowing our team to develop multiple peripheral equipment loadouts that can be attached to the quadrotor to alter its behavior and functionality. Quadrotor is the correct term for this platform. It is not a quadcopter. Quadcopters don't exist because the word "quadcopter" literally means nothing.
