What is a machine tending robot?

In simple terms, a machine tending robot often loads, unloads, and transfers materials between industrial machines. This could range from placing a raw metal piece into a CNC machine for cutting to taking a freshly molded plastic part out of an injection molding machine.

They use built-in sensors, smart programming, and AI-powered decision-making, machine tending robots to adjust to different jobs on the fly. They don’t limit themselves to placing and removing parts — they inspect, clean, and even sort them 

That means fewer defects, less downtime, and a production line that keeps humming long after human workers clock out.

How machine tending cobots work 

Understanding the mechanics of machine tending robots helps clarify why they’re becoming such a hot item. Let's take a closer look at the main components, the software that runs them, and the typical workflow involved.

Main components

• Robot arm: This is the "muscle and bone" of the system. Robot arms vary in size and capability but are generally designed to mimic human movements. Check out more types of robotic arms next. 
  ‍
• End-effector: Think of this as the robot's "hand." It's the part that interacts directly with the material or machine, whether gripping, cutting, or moving items.
  ‍
• Sensors: These are the "eyes and ears" that help the robot understand its environment. Sensors can detect the size and position of materials, ensuring accurate and efficient operation.
  ‍
• Controller: The "brain" that coordinates all the actions. Usually a computer interface, the controller uses software to manage the robot's jobs.

Software

• User interface: Usually a touchscreen or computer program, the UI is where operators input instructions and monitor performance.
  ‍
• Machine learning algorithms: Advanced systems employ machine learning to improve efficiency over time, learning from past operations to optimize future jobs.

Operational steps to follow

1. The system starts with predefined settings or learns the initial state of the workspace using sensors.
   ‍
2. Based on the input from the operator or a pre-set program, the robot arm moves to execute the job. This could involve picking up material, placing it into a machine, operating the machine via connected relays, and then removing the finished product.
   ‍
3. Some systems include a step where the robot or an additional sensor — such as a camera — checks the quality of the output. If something's off, it goes back to the operator for adjustment.
   ‍
4. Once the job is complete, the robot either moves on to the next job in the queue or returns to its home position, ready for the next cycle.

How AI helps machine tending robots

Advanced robots also work with high-end AI, making them more efficient, adaptable, and dynamic.  

Nowadays, these robots are not stuck with a pre-programmed path — they can learn on the job and be redeployed with comparative ease vs a traditional machine tending robot. 

This means you can get much more bang for your buck with an AI robot, even if the initial investment is more expensive. 

Banking on AI is a sure-fire way to future-proof your business.

Benefits of machine tending automation

Yes setting up robotic machine tending takes effort, but the payoff is massive.

Some things to consider: 

• Productivity goes up: Robots don’t take time off and keep production moving 24/7.
  ‍
• Quality control goes through the roof: Every task is completed with the maximum levels of repeatability and accuracy. 
  ‍
• Labor costs drop: Instead of hiring more workers for repetitive jobs, robots handle the hard labor so your team can focus on higher-value work.

• Adaptable automations: AI allows these robots to learn on the fly and adapt not only to changing jobs but to dynamic environments. 
  ‍
• Safer workplaces: High-end machine tending robots can collaborate with humans without safety cages and cut down workplace accidents.

Challenges of implementing robotic machine tending

Throwing a robot onto the production floor isn’t a magic fix — automation comes with its own learning curve.

Let’s take a deeper look: 

• Robots can be prohibitively expensive: Robots aren’t cheap and neither is the setup. But once they’re up and running, they will work faster than humans. Typical costs range from $20,000 to over $100,000.
  ‍
• Your team needs to level up: Machine tending robots don’t run on good vibes alone — workers need training to program, maintain, and troubleshoot them. FANUC, for instance, charges up to $10,500 a week for robotics training. 
  ‍
• Not all robots play nice with old-school machines: Integration can be a headache if your factory still has old hardware. Some upgrades may be needed.
  ‍
• They need regular tune-ups: Robots don’t call in sick, but they do need scheduled maintenance to keep running at maximum efficiency. 

‍

Best types of machine tending robots

Machine tending robots come in all shapes and sizes. 

Let’s take a look at the 5 of the most popular types: 

1. Articulated robots: These robots have rotary joints that can range from simple two-joint structures to complex ten-joint structures, allowing them to mimic human arm movements.
   
   Articulated robots are super versatile and can be used in a variety of applications, including CNC machine tending, where their flexibility allows them to handle complex jobs and work in tight spaces.
   ‍
2. Cartesian robots: Known for their linear movement, Cartesian robots operate along three orthogonal axes and are highly precise. They’re commonly used in applications that require straight-line motion, such as picking and placing parts in injection molding and precise positioning in CNC operations.
   ‍
3. SCARA robots: Selective Compliance Assembly Robot Arm (SCARA) robots are perfect for fast, precise, and repeatable horizontal movements. They’re often used in assembly processes that require high-speed pick-and-place jobs, such as small part handling and packing.
   ‍
4. Delta robots: These robots have spider-like arms, which are connected to a common base. Delta robots are extremely fast and very precise, making them perfect for situations where items need to be quickly picked and placed, such as in packing and palletizing jobs within manufacturing lines.
   ‍
5. Collaborative robots (cobots): Cobots are designed to be safely with humans and are equipped with high-end features that allow them to do so. They’re versatile and can be easily integrated into existing production environments without the need for significant reconfiguration.
   
   Cobots are used in a variety of machine tending applications, including loading and unloading parts in CNC machines and conducting initial quality inspections.

Real-world applications of machine tending robots

There are many applications for machine tending robots, from CNC machine tending robots to packing and palletizing bots. 

Let’s get into a bit more detail: 

• CNC machine tending: Robots are used to load raw materials into computer-controlled cutting or milling machines and then retrieve the finished products. This automation not only streamlines the production process but also reduces the workload on human operators, increasing efficiency and decreasing the likelihood of errors.
  ‍
• Injection molding: In the field of injection molding, robots play a crucial role by adding plastic pellets to molds and then removing the final products once they have solidified. This process benefits significantly from robotic intervention, which pretty much guarantees superhuman consistency and speed.
  
  By handling repetitive jobs, robots can help maintain a steady pace and uniform quality in the production of plastic components — in short, making the operation far more reliable and efficient. 

• Quality inspection: While not their primary function, some robotic tenders can do basic quality inspections during the manufacturing process. These robots can quickly identify and remove defective items from the production line.
  
  This capability helps keep quality standards sky-high by making sure that only products that meet specific criteria proceed to the next stage of manufacturing or packaging.

• Packing and palletizing: Robots are increasingly being used for end-of-line jobs such as packing and palletizing. Machine-tending robots can place machined products into boxes or stack them on pallets, jobs that are often tedious and physically demanding for human workers. 

The use of robots in these roles helps improve the all-around speed and accuracy of packaging operations, reduces labor costs, and minimizes the physical strain on employees, leading to a safer workplace environment.

How to choose the right machine tending robot

Deciding to adopt robotic machine tending is a big step, and choosing the right system can make all the difference. Several factors should guide your decision, each contributing to how well the technology will fit into your existing operations. Let’s take a look: 

Type of machinery you’re going to tend 

First, think about compatibility and job complexity — not all robotic tenders can work with all types of machines. Your existing machinery will dictate what type of robotic system you can implement. 

Make sure the robot you're eyeing is capable of performing the specific jobs required — whether it is simple loading and unloading or more intricate operations like quality inspection.

Some robotic systems are great for straightforward, repetitive jobs, while others are designed for more complex operations. Choose based on the specific requirements of your manufacturing process.

What’s your budget? 

Budget is often a major factor: While robotic systems require an upfront investment, the key is to look at long-term ROI. Weigh the initial costs against the benefits — like labor savings and increased efficiency — to get a clearer picture of the financial impact.

The upfront investment varies significantly depending on the features, brand, and level of customization. You’ll also need to factor in potential changes to your factory layout, new safety equipment, and training costs. 

Give some thought to how long it will take to recoup your investment through labor savings, increased efficiency, and other benefits. With most machine tending robots, ROI is typically just 1–3 years.

Operational requirements

Space and energy needs are also operational considerations: Robotic systems take up physical space. Ensure your facility can accommodate the system without hampering other operations.

Keep in mind that while robots might take up floor space, their energy consumption can also impact utility costs. Different robots have different power requirements, so you’ll want to make sure your facility can meet these needs without excessive energy costs.

Ease of use

A system that is difficult to use can offset some of the efficiency gains. Go for systems with intuitive user interfaces — think about how much time and effort will be required to train your staff to operate and maintain the new system.

Vendor support and maintenance

Never underestimate the value of good vendor support: From warranties and technical support to software updates, vendor services can make or break your experience with robotic machine tending. 

Check if the vendor offers robust customer service and technical support, as this will be crucial when facing operational issues.

Regular software updates can also extend the system's longevity and improve its functionality over time. Make sure the vendor provides this support.

‍

Summing up

Robotic machine tending is making a tangible impact on the manufacturing sector. From handling materials and operating machinery to adding a layer of precision and efficiency, these robotic systems are hard at work modernizing factories.

While the benefits are compelling — increased safety, efficiency, and cost-effectiveness — it's vital to approach implementation with a thorough understanding of both its strengths and limitations. 

The challenges are real, but with careful planning and the right system choice, many of these can be mitigated.
