An automatic operating device that can imitate certain movement functions of the human hand and arm, and is used to grasp, transport objects or operate tools according to a fixed procedure. The mechanical hand is one of the earliest industrial robots and also the earliest modern robot. It can replace human heavy labor to achieve the mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, it is widely used in mechanical manufacturing, metallurgy, electronics, light industry and atomic energy and other sectors.

The tiny mechanical hand possesses magical power and 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 is mainly composed of three major parts: the hand, the motion mechanism and the control system. The hand is a component used to grasp workpieces (or tools). The independent motion modes of a motion mechanism, such as lifting, extending, and rotating, are called the degrees of freedom of a manipulator. To grasp objects at any position and orientation in space, six degrees of freedom are required. The more degrees of freedom a mechanical hand has, the greater its flexibility, the wider its versatility, and the more complex its structure becomes. Generally, specialized mechanical arms have 2 to 3 degrees of freedom. We all know that mechanical hands work very effortlessly. They can lift things heavier than themselves 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 we are about to work on today. We 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 always equal, and the opposite sides are always 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 - helping us save energy or time.
