What Is Mobile Industrial Robots?
Mobile industrial robots are pieces of machinery that are able to be programmed to perform tasks in an industrial setting. Typically these have been used in stationary and workbench applications; however, mobile industrial robots introduce a new method for lean manufacturing. With advances in controls and robotics, current technology has been improved allowing for mobile tasks such as product delivery. This additional flexibility in manufacturing can save a company time and money during the manufacturing process, and therefore results in a cheaper end product.
Mobile industrial robots technology has the potential to revolutionize many sectors of industry; however, it carries with it some disadvantages. The logistics of manufacturing will be streamlined by allowing robots to autonomously navigate to different areas for their work. The labor demands for employees will be lessened as robots will be able to work alongside humans, and mobile industrial robots will assist with medicine and surgery more and more. However, there are drawbacks to this technology.
Coordinating the movement of industrial robots and robotic arms around facilities and calibrating their position at their destination is tedious and far from perfect. A robot malfunctioning in a manufacturing setting will hold up production – and these industrial robots and robotic arms could malfunction anywhere in a facility. Human safety must also be considered. Mobile industrial robots must prioritize the safety of human operators over their programmed task – which may complicate the coordination of multiple autonomous robots. Especially in a surgical setting, there is no room for error on the robot’s part. Even though some challenges are present, mobile industrial robots technology promises to streamline aspects across much of the industry.
History Of Mobile Industrial Robots
Mobile industrial robots began in the automobile industry in the years surrounding WWII (1946). At first, the term was used to describe the increased presence of automatic devices in production lines and solely manufacturing contexts. Now, automation is widely used in many industries where computerized action and feedback loops can replace human intervention in the workplace. Over time, development in this area has become increasingly dependent upon advanced computer technologies and the advancement of processing capabilities.
In its current form, most industrial mobile industrial robots are powered mechanical arms with the ability to perform anthropomorphic actions. Advancements in miniaturization of computers, mathematical control theory as well as improved sensory technologies have had a great impact on the feedback control systems that drive robotics.
The first industrial robots and robotic arms performed spot welding and die castings in a General Motors factory in New Jersey, the USA in 1962. Soon, robotic arms were exploding within the large-scale manufacturing industry and several new companies came into existence including Kuka in 1973, Nachi in 1969, Fanuc in 1974, Yaskawa in 1977, ASEA in 1977, and several others. By 1980, it is estimated a new major robotics company entered the market every month.
Mobile industrial robots are now set to experience similar expansion as they become significantly more reliable in an industrial setting. Even if a industrial robots and robotic arms make mistakes, it will eventually be less frequent than mistakes caused by human factors.
Types Of Mobile Industrial Robots
There are different types of mobile industrial robots based on specifications and applications. Various types of industrial robots include non-servo robots, servo industrial robots and robotic arms, programmable robots, and computer programmable robots.
These industrial robots and robotic arms are used to move and place objects. That means these robots will be capable to pick up an object and transport the object, place it down.
Servo industrial robots and robotic arms include manipulators, effectors, robotic appendages that function as the arms and hands of the robot.
These industrial robots and robotic arms store commands in a database i.e. they can repeat a task a pre-determined number of times.
Computer programmable robots
These industrial robots and robotic arms are essentially servo robots that can be controlled remotely, via a computer.
Classification By Types Of Industrial Robots And Robotic Arms
Robots are mostly classified into five major configurations based on their mechanical structure. They are:
Cartesian robot consists of three prismatic joints and axes are concurrent with a Cartesian coordinate system
SCARA (Selective Compliance Assembly Robot Arm) robot is included with two parallel rotary joints to provide compliance in a plane.
Articulated robot is a robot whose arm has at least three rotary joints
A parallel robot is a robot whose arms have concurrent prismatic or rotary join.
Features Of Industrial Robots And Robotic Arms
Each mobile robot will incorporate different features that optimize the system to meet a specific goal or perform a certain task. However, industrial mobile robot systems, perhaps the most commonly used today, possess several core features that should always be present. These features are:
Fleet simulation software
Fleet management software
Integration with the company’s supervisory software
Uses And Functions Of Industrial Robots And Robotic Arms
The basic functions of a mobile robot include the ability to move and explore, transport payloads, or revenue-producing cargo, and complete complex tasks using an onboard system, like robotic arms. While the industrial use of mobile robots is popular, especially in warehouses and distribution centers, its functions can also be applied to medicine, surgery, personal assistance, and security. Ocean and space exploration and navigation are also amongst the most common uses of industrial robotic arm.
Industrial robots with vision are being used to access areas, such as nuclear power plants, where factors, like high radiation, make the area too dangerous for humans to inspect and monitor themselves. However, current mobile robotics is not designing robots that can tolerate high radiation without their electronic circuitry being impacted. Attempts to invent mobile robots to deal specifically with these situations are currently being made.
Other uses of industrial robots with vision include:–
Shoreline exploration of mines;
A robotic pack dog or exoskeleton to carry heavy loads for military troopers;
Painting and stripping machines or other structures;
Industrial robotic arm to assist doctors in surgery;
Manufacturing automated prosthetics that imitate the body’s natural functions and
Patrolling and monitoring applications, such as surveilling thermal and other environmental conditions
Advantages Of Industrial Robots With Vision
Safety Precautions For Industrial Robots With Vision
Since industrial robots with vision, especially AMRs, are loaded with cameras and sensors, they are able to understand their environment at a higher level, thus, as mentioned before, eliminating the risk of human negligence and the accidents and other safety risks that could occur as a result of human error to make a industrial robotic arm.
However, since the field of mobile robotics is rapidly expanding, it is necessary to create safety standards and guides specifically for industrial robotic arm. Currently, the only relevant safety standards come from a combination of the American National Standards Institute (ANSI), the Industrial Truck Standards Development Foundation (ITSDF), and the Robotic Industries Association (RIF). The guides are the ANSI/ITSDF B56.5-2012 Safety Standard for Driverless, Automatic Guided Industrial Vehicles and Automated Functions of Manned Industrial Vehicles and the ANSI/RIA R15.06-2012 Industrial Robots and Robot Systems – Safety Requirements.
Although both guides are important, they fail to cover some of the latest technology. Safety standards that cover all areas of mobile robotics must be made and monitored to ensure the well being of human workers, especially as advancements are made and new features are added to industrial robotic arm
The RIA and ANSI are currently working together with other key industrial robotic arm representatives to develop a guide of safety standards specifically for industrial mobile robots, called R15.08. The standards will be published in three parts:
Part one will define the safety requirements for manufacturers of industrial mobile robots.
Part two will outline the different requirements for companies that are looking to create, install, and integrate a secure mobile robot system.
Part three will specify the safety requirements for end-users of industrial mobile robots.

Frequently Asked Question:
Are autonomous mobile robots safe?
AMRs are collaborative and designed to work alongside humans. Being completely safe is the main feature of collaborative mobile robots that run in dynamic environments and work alongside humans. In case a human stumbles in front of an AMR, a safety-rated laser scanning system interprets the obstruction fast enough to either reroute or stop completely to prevent a collision. The MiR AMRs.
What’s the typical return on investment on lightweight industrial robots?
The easy integration and the fact that companies do not need to make changes in the existing factory layout when integrating AMRs allow low initial costs. Moreover, AMRs are a reliable workforce that can run for around 12 to15 hours without breaks. They can charge automatically, when they do not have tasks to perform, ensuring a smooth workflow, and optimizes the internal logistics. The ROI is typically less than a year, due to this easy integration and because one robot usually – depending on the application – frees up two full-time employees to perform higher-value tasks.
