Motor motion control system in mobile robot
Release Date : 2020-08-14 17:33:35



Automated mobile equipment can transport goods in warehouses and freight centers and perform assembly operations, thereby increasing the demand for power transmission and motion control systems. In fact, studies have shown that by 2026, the global mobile robot market will reach 15 billion US dollars. Almost all electric power transmission systems are relatively expensive in the early stage, but due to the use of electricity as power and moderate maintenance, they have high controllability and their cost will be greatly reduced, such as the current multi-purpose vehicle (UTV) and All-Terrain Vehicle (ATV).
 
Of course, many automated guided vehicles (AGV) and other professional service robots (including robots for logistics and remote inspection) have control systems to perform specific tasks. These require complex motion control, and the shapes of these robots are numerous and numerous, including grippers, linear actuators, multi-axis platforms, and motion systems for handling and transporting payloads.

A typical motion curve in mobile robot systems is high-duty cycle precise rotational motion, especially for position sensing components, such as light detection and ranging (LiDAR) and other tracking systems on autonomous vehicles; lidar To sense the surrounding environment of the mobile robot to avoid collisions with other vehicles.
 
This motion sensing system is the core of the autonomous mobile robot (AMR) function, which moves items in factories and warehouses from origin to destination. These sensing systems are usually PC-based motion control. The command controls the wheel-driven servo motors, while networking to realize the ERP connection of the IIoT function.
 
The technology of material handling automation was originally developed for aerospace and military applications. In recent years, the increasing level of material handling automation is largely due to the birth of increasingly cost-effective material procurement and production technologies.
 
Many new motion designs for robotic systems are designed to automate material handling.
 
In warehouses and material handling AGVs, there is an increasing demand for automatic material handling vehicles, which usually use brushless motors paired with encoders and electronic devices to drive their traction wheels. Choose the right motor for your AGV car (automatic guided vehicle)
 
Small and medium-sized companies are entering the field of robotics to create innovative technologies for the medical, consumer and industrial industries. Therefore, seeking a server manufacturer that can provide a complete solution is a very advantageous technology for small robot manufacturers.
Mass customization is a typical representative of motion components and systems in independent design. Usually, the first thing is to reduce the total number of parts designed. Some motion control companies use fully custom designs.
 
In fact, one design challenge for AGVs and similarly designed wheel drives is that the axially mounted motors with multi-stage spur or planetary gears (common in traditional wheel and belt drives) are usually too large. Therefore, in order to solve this problem, a customizable and small-sized wheel drive includes a brushless DC motor or a servo motor.
 
The planetary gear device is a supplement to the electronically commutated (brushless) DC motor; the bevel gear box connects the motor to the input shaft of the hub gear to achieve high power density wheel drive. The motor efficiency exceeds 90%, and the lightweight low-loss gear maximizes the efficiency.
