Bipod comes from the Latin and Greek roots bi and pod, meaning "two" and "foot, or feet" respectively. A bipod is an attachment for either a photographical device or a weapon that creates a steady plane for whatever it may be attached. It provides significant stability along two axes of motion (side-to-side, and up-and-down). The concept for a bipod dates back to pre-20th century times, and is still used today by agencies such as NASA.
On firearms, bipods are commonly used on rifles and machine guns to provide a forward rest and reduce motion. They are also seen on other long-barrelled weapons. Bipods permit operators to easily rest a weapon on objects, like the ground or a wall, reducing their fatigue and increasing accuracy and stability. Bipods can be of fixed or adjustable length. Some can be tilted and also have their tilting point close to the barrel's central axis, allowing the weapon to tilt left and right. There are three ways for bipods to be folded: away from the shooter, towards the shooter, or into a vertical foregrip.
NASA and Rocket Technology
The simple design is also included in circumstances such as NASA’s space shuttle launches. NASA honed the idea in a different way, they used the bipod system to create a launch pad for their rocket ships to launch off, it basically acted as a track for the rocket to propel on. The bipod launch system revolutionized the way space shuttles lift off into space, in a straight vertical line. More recently, rockets have scaled to a much smaller size, thus leading to a new hobby of model rocket building. The design of the toy is very simple, it includes a silver launch pad at the bottom and two metal rods that act as a bipod for the scaled rocket to launch.
