[ Hot Focus on Chemical Machinery and Equipment Network ] In various places such as the front line of manufacturing and logistics, medical facilities and welfare facilities, and homes, robots that replace human work are showing their talents
.
There are many kinds, in addition to factory automation equipment and automatic guided vehicles (Auto Guided Vehicle: AGV), there are welcome robots, nursing robots, and communication robots that provide rehabilitation and entertainment at home
.

Chemical machinery and equipment network hotspots focus on chemical machinery and equipment

Robots are divided into "industrial robots" and "service robots"
.
Industrial robots that work on the front line of manufacturing such as factories replace humans to perform prescribed operations in an environment without human contact, while service robots are engaged in services such as welcome and nursing, mainly in public places near humans such as shops and offices
.
Ensuring safety is a prerequisite for service robots to coexist with humans
.

Service robots are gradually becoming popular around the world.
In the future, with the upgrade of sensors and systems, new robots are expected to appear and become more and more closely related to our lives

　　Among service robots, "accompanying robots*1" that play the role of pets or family members in the home use AI-based chat functions and smooth movements to make people forget that they are actually actions performed by machines
.
It has also gained traction as a way to ease loneliness as human-to-human communication diminishes in today's society
.

　　The smooth and natural movements of this robot are inseparable from the performance of the motor and components such as the "controller" and "angle sensor" that control the motor
.
The movable parts of the robot body such as arms, body, and wheels are equipped with small servo motors, and the controller will precisely control the movements of each motor
.
At the same time, the angle sensor accurately detects the angle and speed of the motor rotation
.

　　In order for small robots such as companion robots to perform natural and accurate movements, it is necessary to make use of high-precision angle detection and high-speed response performance to achieve the best torque response of the motor
.
Therefore, high-precision angle sensors and small embedded controllers will play an important role
.
The TAS/TAD series are showing their talents in a wide range of applications including service robots
.

　　How capacitive proximity sensors work: Capacitive proximity sensors are used to detect changes in capacitance between sensors
.
The size of the capacitance depends on the size and distance of the sensing object
.
A common capacitive proximity sensor is similar to a capacitor with two parallel plates, where the capacity of the two plates is sensed
.
One of the boards is the object under test (with an imaginary ground) and the other board is the sensing face of the sensor
.
The capacitance change that occurs between these two poles is detected
.
The objects that capacitive proximity sensors can detect depends on their dielectric constant, but they include resins and water in addition to metals
.

Capacitive

　　The industrial robot hand gripper is a mechanical structural component with multiple degrees of freedom and dexterity to grasp objects
.
It is suitable for the production, assembly and operation of various industrial automation, and can complete the work of information detection, material collection, detection, and detonation in high-risk environments
.
The industrial robot hand gripper generally adopts a clamp-shaped structure, and the object is clamped by opening, closing and clamping
.
Therefore, the accurate measurement and control of the jaw opening is the key factor to determine the success or failure of clamping
.

　　Because the proximity sensor can sense changes in distance and position, it is a commonly used measurement opening and closing element in industrial robot hand clamps, which uses the relative positional relationship between the change of the magnetic field and the metal parts to be measured to carry out measure
.
Usually, the proximity sensor is mounted on one of the jaws of the industrial robot gripper, which is gripping
.
When an object is clamped, the proximity sensor can determine the distance between the two by sensing changes in the magnitude of the magnetic field
.

　　The vision sensor is generally installed on the gripper in the gripper of the industrial robot.
By sensing the change in the size of the magnetic field, the proximity sensor can judge the distance between the two hands (pliers)
.
In this way, it can be compared with the set value to adjust the opening of the industrial robot hand gripper to avoid emptying or damaging the object
