1) Cartesian coordinate industrial robots
Its moving part consists of three rectilinear movements (i.e., PPPs) perpendicular to each other, and its workspace graphics are rectangular. It can be directly read out on each coordinate axis of the moving distance in each axis, strong intuitiveness, easy to program and calculate the position and attitude, high positioning accuracy, no coupling of control, simple structure, but the space occupied by the body is large, the range of action is small, the flexibility is poor, and it is difficult to coordinate with other industrial robots.
2) Cylindrical coordinate industrial robots
Its motion form is realized by a motion system composed of a rotation and two movements, and its working space graphic is a cylinder, compared with Cartesian coordinate industrial robots, under the same working space conditions, the body occupies a small volume, and the range of motion is large, and its position accuracy is second only to Cartesian coordinate robots, and it is difficult to coordinate with other industrial robots.
3) Spherical coordinate industrial robots
Spherical coordinate industrial robot, also known as polar coordinate industrial robot, the movement of its arm is composed of two rotations and a straight line movement (i.e., RRP, a rotation, a pitch and a telescopic movement), and its working space is a sphere, which can do up and down pitching action and can grasp the coordinated workpiece on the ground or teach a low position, its position accuracy is high, and the position error is proportional to the arm length.
4) Multi-articulated industrial robots
Also known as rotary coordinate industrial robot, the arm of this industrial robot is similar to the upper limb of human integration, and its first three joints are the slewing pair (i.e., RRR), the industrial robot is generally composed of a column and a large and small arm, the column and the big arm are seen to form a shoulder joint, and an elbow joint is formed between the big arm and the small arm, which can make the big arm do rotary motion and pitch swing, and the small arm does pitch swing. Its structure is the most compact, flexible, and occupies the smallest area, and it can work in coordination with other industrial robots, but the position accuracy is low, there are balance problems, and the control coupling is becoming more and more widely used.
5) Plane articulated industrial robots
It uses one moving joint and two rotary joints (i.e., PRR) to move the joints up and down, while two rotary joints control the forward-to-back, left-right movements. This form of industrial robot is also known as SCARA (Seletive Compliance Assembly Robot Arm). In the horizontal direction, it has the flexibility, and in the vertical direction, it has the rigidity of the University. It has simple structure and flexible action, and is mostly used in assembly operations, especially suitable for plugging and assembling of small-sized parts, such as plugging and assembly in the electronics industry.

Universal Robots – an introduction to the features of laser welding robots
1. It has non-contact, and the minimum point diameter formed by the laser can be 0. 1 mm, the minimum solder feeding device can be 0.2 mm, and it is possible to solder micro-pitch packaging (mounting) components.
2. Because it is a short-term local heating, the thermal impact on the substrate and surrounding parts is very small, and the quality of the solder joints is small.

Universal Robots - What are the categories of industrial robots according to their mechanical structure?
1. Single-axis robot
Single-axis robots are generally divided into two transmission modes, one is ball screw transmission, and the other is synchronous toothed belt (abbreviation: synchronous belt) transmission, both of which are guided by linear guide rails, and cooperate with servo motors or stepper motors to achieve the determination of different application fields.

Universal Robots – a classification of tactile sensors for industrial robots
1. Optical tactile sensor
There are two types of optical tactile sensors: inside and outside. In this type, the intensity of the light is adjusted by moving the obstacle to the light path. It has the advantage of being immune to electromagnetic interference and has a high resolution. Low wiring is required and the electronics can be kept away from the sensor.
