       It can imitate certain movement functions of the human hand and arm，Used for grasping according to a fixed procedure、An automatic operating device for handling objects or operating tools。The mechanical hand is one of the earliest industrial robots to appear，It is also one of the earliest modern robots to appear，It can replace human heavy labor to achieve the mechanization and automation of production，It can operate in harmful environments to protect personal safety，Therefore, it is widely applied in mechanical manufacturing、Metallurgy、"Electronic"、Departments such as light industry and atomic energy。

    The tiny mechanical hand possesses magical power，It can help us grasp some heavy objects，As long as you operate its control system，It will obediently bring over what you want。Do you want to have a mechanical hand of your own？Then let's study it together！

    A mechanical hand mainly consists of a hand、It consists of three major parts: the motion mechanism and the control system。The hands are used to hold workpieces（Or tools）Components。Lifting and lowering of the motion mechanism、Expansion and contraction、Independent motion modes such as rotation，It is called the degree of freedom of the mechanical hand。In order to grasp objects at any position and orientation in space，It is required6Degrees of freedom。The more degrees of freedom，The greater the flexibility of the mechanical hand，The wider its universality，Its structure is also more complex。Generally, there are specialized mechanical hands2—3Degrees of freedom。We all know that mechanical hands work very effortlessly，It can lift things heavier than itself with ease。How on earth does it work？Let's study it。

Let's all take a look at the structure of the mechanical hand that we are about to work on today，You will find that its hand is very much like a parallelogram。A parallelogram refers to a quadrilateral in which two pairs of opposite sides in the same plane are respectively parallel。No matter how the shape changes，The opposite sides of a parallelogram are all equal，The diagonals are all equal.。

Moreover, we also found that each connection point is a small lever。A lever is a hard rod that can rotate around a fixed point under the action of force。Levers can be used in many places in our lives——Help us save effort or time。

    For example, labor-saving levers：Bottle opener、Juicer、Walnut pliers … …

    Effort-saving levers, for example：Scissors、Hammer、Nail remover … …
