1 industrial robot is a machine or the people?

When it comes to industrial robots, people immediately associate is theSuperman cartoons of the "Transformers" or movie. "". However, in reality the robot always people shaping the "robot" idol is not a small distance. Even the world's more advanced robots, such as Japan's Honda Corporation robot is no more than a more intelligent humanoid robot, the robot will be a machine, not people.

We come to have a look by industrial robot Chinese fans speculation is to be defined. The word "robot" is defined in the English in extensive far from Chinese"robot" is a word, such as a printer can be called "robot", an intelligent machinecan also be called "robot" intelligent mobile phone, even if the Android system isGoogle known to the definition of "robot"...... If Chinese give a definition is moreprecise, should be called intelligent machine production industry, pictographiccan be widely accepted Chinese field description is "industrial mechanical arm".

Yes. Industrial mechanical arm!

That is so called, I was in the exhibition, customer promotion conference heard several users in such a call. For the call I had secretly that do not agree with, justone word, the word "manipulator" kill "robot" new personality. However, after 2 years in the industry to touch up, finally able to identity "naming and define the mechanical arm"! However, after 2 years in the industry to touch up, finally able to identity "naming and define the mechanical arm"! Because, it is similar to the one arm machine in your visual impression in it, it is not as intelligent as humanmagic to. Composed of 2 industrial robot system

2.As the arm activities:

from basic bone skin, need to consume energy by flexing muscles, the size of the brain and nervous system to control action.

Mechanical arm has such structure:

(1) mechanical system:

As a human arm from shoulder joint to the middle finger, the elbow wrist, armstructure size transition.

The mechanical arm can be rotated by the base, arm, wrist and the "joint", but this is a body strong as iron, cold machine, is nothing more than a steel or aluminum alloy castings, iron pieces. The robot "joint" is not like the human jointis spherical rotation, but the fan shaped rotating.

The mechanical arm is relying on such a structure, this part because ordinary machine is no different, so called "mechanical system"

(2) drive system:

Such as a retractable pulling human arm muscles, mechanical arm movementalso need such can provide some driving energy.

The mechanical arm drive system by power into hydraulic, pneumatic and electricthree categories. At present the mainstream is driven by servo motor motion, and can also be composed of three basic types are combined into a compound drivesystem.

Sifu motor drive way has become the mainstream, because the servo motor withprecision gear, can precisely control the joint rotation range, the precision to the 0.01mm level. The degree of precision that depends not only on the servo motor,but also with a part of the "mechanical system" and a "control system" is closely related to the servo motor, the principle and the reduction gear in this not to repeat them, interested can search to understand.

(3) control system:

Have the brains and nervous systems, the mechanical arm was known as the"robot" or similar part of its name, the control system, mechanical arm of the sizeof brain and neural network.

The control system is composed of a drive through the computer software and hardware platform servo system "brain and nerve center", precision motion robot(such as the direction of rotation of the number of degrees, with what kind ofaction) is through the part precision calculation giving instructions.

The core of control system through the computer operating system and movement model database (can be understood as stretch, shrink, rotatingmodel), for digital to analog conversion of various motion commands, and will bean action (such as stretch forward 2m) decomposition of motion for a range of different joints, the servo drive transmits the determined pulse (can be understood as the effort) to each joint of servo motor, servo motor according to the received instruction accurate rotation.

The whole movement instruction by artificial operation after editing form the computer code stored in the computer memory, and do the action according to set a good program, the sensor can also be through external (such as machine vision, force sensing) received feedback signal for moving. In fact, the industrial robot to "people" but not with more rigid machine, it is also because it through the computer brain can process the external signal relative intelligence.

3. joint robot we called for 1 axis is more appropriate, because each of the 1 jointcan be completed only one dimension of rotation. Industrial mechanical arm and the distinction between "joint" because the number of different, from the simple 3joint to the 6 joint robot arm is more unequal, joint.

The robot "joint" for the deployment location and composition of the differentstructure is different, also can be divided into "parallel" (delta), "series", "series"(Scara): figuratively, parallel is like the two diagonal of a parallelogram,parallelogram deformation occurs, the diagonal "joint" at the same timeequivalence movement; and the series is like the arms of a man as one-way connection.

Degrees of freedom of the robot by the joint number and joint connection form.Length of be confined to, not to repeat them, in this based on the "parallel"(delta), "series", "series" (Scara) of three common structural metaphordescription:

(1) "parallel" (Δ) robot is widely known as the "spider hands", because although it has a lot of joint of finger end, but it only in a deterministic action reaches a point, at the end of spider hands always toward a direction

(2) "series" (Scara) robot similar to the toy snake, which is the basic motion in a horizontal plane through the swinging "expansion", the common Scara robotbecause at the end of the installation of the upper and lower extension axis than the toy snake more "flexible", to refer only to "the head" through the jaw fromocclusal joint movement up and down. The Scara 4 axis robots and "spider hands" can only make limited action, it will only be determined by an action to apoint.

(3) "series" robot is different from the "spider hands" and "Cobra", because it is awide degree of freedom, a series of rotating structure of robot joints at least not in the plane of one dimension, so at the end of it can be flexible action, typical example: at the end of the robot can do any action around space.
