A few things you need to know about industrial robots

Definition: A robot is a robot with multiple degrees of freedom in three-dimensional space, which can achieve a variety of anthropomorphic actions and functions

Features: Programmable, Anthropomorphic, General, Mechatronics.
　　
2. What is the subsystem of industrial robots? What are their characters?

Drive system: The transmission equipment that enables the robot to operate.

The mechanical structure of the system: the degree of freedom of the mechanical system of the multiplicity of the end of the main body of the operating arm composed of three pieces.

Sensing system: It is composed of an internal sensing module and an external sensing module to obtain information about internal and external environmental conditions
。
Interaction system between robots and the environment: A system for industrial robots to interact and coordinate with equipment in the external environment.

Human-computer interaction system: It is the equipment that the operator participates in the robot control and contacts with the robot

Control system: The operation instructions of the robot and the program from the actuator signal of the sensor are fed back to complete the function of directing the robot's movement and booking.

3. What is the comfort level of the robot? How much comfort does the robot need to operate in the direction? How much freedom do you need to operate in posture? Why?

Comfort refers to the number of times a robot moves independently of an axis. It should not include the end-of-machine effects of the gripper. It requires 6 degrees of freedom to depict the orientation and posture of an object in 3D, 3 degrees of comfort (waist, shoulder, elbow) for orientation operations, and 3 degrees of comfort (pitch, yaw, roll) for posture operations. However, the degree of freedom of industrial robots, and the degree of freedom of industrial robots is planned according to their intentions, which can be less than 6 degrees of freedom or greater than 6 degrees of freedom.

4. What are the primary technical parameters of industrial robots?

Answer: Freedom, repeatability, work range, the largest work speed, carrying capacity.

5. What is the function of the body and arms? What should I look for in planning?

Answer: The fuselage is a part of the support arm part, which generally realizes reversal and pitching movements such as lifting and lifting.

When planning the fuselage, you need to pay attention to:

1) It has satisfactory stiffness and stability;

2) the movement is flexible, and the vertical movement of the length of the guide sleeve should not be too short to prevent the jamming phenomenon, and there is generally a guiding device;

3) The arm is a component that supports the static and dynamic load of the wrist and the workpiece, especially when the arm moves at high speed, it will produce a large inertial force, cause impact, and affect the positioning accuracy.

When planning your arms, keep in mind:

1) High stiffness requirements;

2) Good orientation;

3) Light weight;

4) Stable movement and high positioning accuracy.

Other transmission systems should be as simple as possible to improve transmission accuracy and power; The layout of each component should be reasonable, easy to operate and maintain; Special cases should be considered, and corrosion protection should be considered in corrosive environments affected by thermal radiation in high-temperature environments. The prevention of violence should be considered in dangerous environments.

On the wrist, what is the first effect of 6 degrees of freedom? What kind of comfort should there be if the demand, on the other hand, can be in any direction of the space wrist?

Wrist comfort is first and foremost about achieving the desired posture of the hand. In order for the hand to move in any direction in space, the wrist is required to be able to rotate three axes X Y Z in space. That is, it has three degrees of freedom of overturning, pitching and deflection.

6. Effects and features of the hands

Effect of the Robot Hand: The industrial robot hand is also known as the finished operation and is used to hold the workpiece or tool member

Characteristic:

1) The hand is a separate part;

2) The completion of the operation is the hand of the industrial robot. The structure is not necessarily the same as the person to start with. A finger may or may not have one: a jig can also be a specialized tool;

3) Hand and wrist joints can be separated;

4) Poor versatility of the hand.
