AGV/AMRs

In people private livesWe are usually familiar with robot vacuum cleaners.And the concept of self-driving cars.Now, all industriesStart investing in automation on a global scaleTo improve production and logistics.With the flexibility of work, AGV provides a good choice to start moving or uninstalling automation system.
AGV / AMRs is an abbreviation used to describe autonomous vehicles used to transport products or materials around them. warehouse or manufacturing plant which can help increase efficiency and productivity At the same time reducing damage and reducing the cost of products, for example, large vehicles. It can be replaced with smaller AGV/AMRs , thereby maximizing storage density.
AGV / AMRs are vehicles, simply referred to as vehicles that are used for unmanned indoor transportation. that helps to move goods and equipment inside the warehouse and industrial plants accurately Outstanding weight support and conveying properly and safely even without light or able to work with humans effectively
moreover This is essential for any new business in this era that operates on manufacturing. And the warehouse must make the system more efficient. The use of Automated Guided Vehicles (AGVs) and Robots has therefore become popular. And its also a way to lead in the digital world.

How AGVs /AMRs can increase your productivity

With a highly competitive market and change throughout the year. Thus leading to the era of IOT (Internet of Things) or Industry 4.0, manufacturers are looking for different methods. to be a market leader as well as the rise of automated warehouse systems both in general warehouses and in industrial plants.
AGV and E-COMMERCE, AGV vehicles or Robot AGVs have been brought into warehouses until they are continuously popular. because it is a complex area Every day, a large number of goods are imported and exported. There are also various types of products. Location management, order picking, replenishment, stock management , if used by one person alone can cause delays and a high chance of error. In the E-COMMERCE market, the world leader in logistics, Amazon Or Alibaba has used AGVs to manage a large number of products in an intelligent warehouse system .
AGV and Manufacturing With the ability to withstand heavy loads in handling and conveying, the Robot AGV can greatly increase the efficiency of operations in industrial production lines for handling pallets, raw materials or finished goods .

How many types of AGV/AMRs are there?

These vehicles can be divided into two. Main categories include:
- 1. Navigation system type
- 2. Intelligent navigation system

1. Navigation system

But before AGV It is a call used to describe a car that moves autonomously.The AGV will be booted by configuring it.Markers detected by a set of sensorsSome applications may require multiple tags to provide AGV.The most popular navigation method is
- Upper sensor for laser positioning by this methodAGV It will scan the workpiece placed at a known position in the workspace again.Then the vehicle analyzes the signal from the workpiece again.And calculate the accurate relative position.And a strip algorithm.
- Other navigation methods include magnetic tape navigation Built-in wired navigation map navigation and light navigation
These navigation and methods vary depending on the type of sensor or marker used.

2. intelligent navigation

AMRs is a breakthrough of AGV technology, defined by AMR.That is running without navigation Nor is it based on various markers.Guide them to their destination.In some cases, new destinations are needed.Magnetic stripe may be the first choice for newer AMRs applications.More intelligently, there is now 2d or 3d mapping.Including cameras, sensors and algorithms with more complex dimensions.Let more AMRs make their own decisions.Sensors are used, among which lidar is the most popular choice.The laser sensor adopts pulse laser.And the high sensitivity detector is explored.And measure the distance from the object. This is helpful for localization.And mapping technology, while generating mapping from unknown environment.And keep the position inside that map through this advanced control.AMRsIt can set its own path to avoid blocking.

This paper mainly introduces the design of AGV/AMR carAGV and AMR.It can be divided into five main parts: battery, control box,Sensors, mechanisms and propulsion systems

atteryThe energy of the car is the energy required by every electrical equipment in the car.The types of batteries used include lead and acid water,Nicad, lithium ion, inductive power supply and batteryBefore the battery is exhausted, AGV/AMRSome models will recommend replacing the battery to keep it working.Some can be programmed back to the charging station.
The control box is like the brain command of AGV/AMR.Use PLC, PAC or IPC for control.A data program may be needed to complete the corresponding work.HMI programming, through Touchscreen orInput panel is like input.
Different types of sensorsIt acts on the eyes of the vehicle and provides information about the vehicle environment.Obstacles can be detected in two ways:Pressure sensor for laser sensing or mechanical collision detectionAccording to ANSI/ITSDF B56 safety standard. 5-2012Serve as a guide to AGV/AGV operation requirements.AMR also uses a return signal device.Such as an encoder, a solver or a Hall effect sensor.To calculate the distance traveled and check the speed of the vehicle.
Any movementThe external drive system is classified as peripheral mechanism, and in most vehicles, there may be lifting mechanism.To lift the weight, and may become the air intake tray of the door.Or an arm controlled by a motor or actuator.
drive system It consists of a wheel drive shaft, an electric motor and a gearhead. These components move and control the vehicle. Typically, the direction of the car is controlled by the rotation of the wheels in synchronization or independently.
