Abstract
A universal dart launcher launches a dart by moving a dart from a first position to a second position. The universal dart launcher has a launcher body defining a central bore having an axis and lower and upper ends configured to attach to a string of pipe. A cartridge housed within the launcher body may move perpendicular to the axis from a first position to a second position. A drop member is positioned within the cartridge so that it will not be in axial alignment with the central bore while in the first position, and will be in axial alignment with the central bore while in the second position. An actuator assembly couples to the launcher body to move the cartridge from the first position to the second position when actuated.
