No, planetary gearboxes and cycloidal gearboxes are not considered to be a rotary vector gearbox. A rotary vector gearbox, also known as a RV gearbox, is a type of gearbox that converts a rotating input shaft into a rotating output shaft with the same speed, but a different direction. It is commonly used in applications where compact size and high torque transmission are required, such as robotics, aerospace, and industrial machinery. On the other hand, planetary gearboxes and cycloidal gearboxes are types of gearboxes that are designed to provide high torque and speed reduction, but do not change the direction of rotation.
