When I sat down to research this article, I wasn’t sure what I would learn. What exactly are humanoid robots, and are they a viable labor force solution? Can they operate sophisticated equipment or only perform simple tasks? How much faster are they than human workers?
Humanoid robots, or robots that look and move like humans, still look like a thing of the future, but they’re already being used in some industries today and have the potential to report for duty on the packaging line in the near term. General-purpose robots like humanoids are different from the robotics and automation we write about daily here at Packaging World. We’re not talking about one piece of equipment that does one thing (albeit very fast and efficiently). We’re talking about a robot that can be programmed and “taught” to do many things, like kitting, material replenishment, order picking, palletizing, and lifting/loading. Is there a place for a general-purpose robot in packaging facilities today?
General Purpose Means Greater Functionality
The robots mentioned above are programmed to do one task and do it well. General-purpose humanoid robots such as Phoenix from Sanctuary AI, a Canada-based robotics company, can handle a variety of tasks thanks to its full body mobility. This gives users the flexibility of using the humanoid robot to automate any pressing task at any pressing time.

Humanoid robots, or robots that look and move like humans, still look like a thing of the future, but they’re already being used in some industries today and have the potential to report for duty on the packaging line in the near term. General-purpose robots like humanoids are different from the robotics and automation we write about daily here at Packaging World. We’re not talking about one piece of equipment that does one thing (albeit very fast and efficiently). We’re talking about a robot that can be programmed and “taught” to do many things, like kitting, material replenishment, order picking, palletizing, and lifting/loading. Is there a place for a general-purpose robot in packaging facilities today?
General Purpose Means Greater Functionality
The robots mentioned above are programmed to do one task and do it well. General-purpose humanoid robots such as Phoenix from Sanctuary AI, a Canada-based robotics company, can handle a variety of tasks thanks to its full body mobility. This gives users the flexibility of using the humanoid robot to automate any pressing task at any pressing time.
Phoenix is the company’s sixth-generation robot designed to overcome the challenge of bringing a general-purpose robot to market. Phoenix can perform daily tasks such as picking and can work alongside humans. Phoenix is 5’7”, weighs 155 pounds, and can lift up to 55 pounds. Perhaps the robot’s most impressive feature is its hands that feature “20 degrees of freedom and haptic sensors” that allow it to perform tasks that require dexterity.
“A critical component needed to make robots truly general-purpose, is dexterous hands,” says Geordie Rose, CEO & co-founder of Sanctuary AI. “This is an area that Sanctuary AI has been intently focusing on. Each with 20 degrees of freedom and proprietary haptic technology, Phoenix’s hands are designed to be as close as possible to human hands in their dexterity and fine manipulation capabilities. Our haptic technology provides the robots with a sense of touch which is essential to perform tasks successfully.”
Sanctuary AI isn’t the only robotics company with a humanoid in the market. Apollo, from Apptronik, an Austin, TX-based robotics company, is a human-like robot that is designed for use in manufacturing. Apollo is 5’8”, can lift up to 55 pounds, and can operate for four consecutive hours. Apollo excels at moving goods from one spot to another in a plant and working in conjunction with autonomous tuggers to fully automate kitting.
“Apollo will solve many of the near-term manufacturing and logistics use cases that have not been addressed by special-purpose automation solutions to date. This includes automated lineside/work cell delivery or machine tending of totes in manufacturing as well as trailer unloading, case picking, or palletizing,” says Jeff Cardenas, co-founder and CEO of Apptronik.
According to the company, Apollo shines in tasks that are considered “gross manipulation,” or gross motor function, like grabbing something with both hands. As technology develops, Cardenas predicts that the robots will be able to move to finer dexterity tasks (complex tasks) over time. Specific to the packaging line, Cardenas says that Apollo would excel at material replenishment tasks like loading blank cartons into a cartoner, adding a new roll of film to a form/fill/seal machine, and even handling simple packaging machine changeover.
“These tasks are fair game, but maintenance tasks can be more difficult because they’re not as repeatable, so they require problem solving,” says Cardenas. “The initial tasks that Apollo can do today involve tasks that are simpler and more repeatable, but with AI improving more and more each day, the ability to handle these more complex tasks and problem solve become more viable."
Look at Real-Life ApplicationsAnother robot in market today is one from 1x, a robotics company backed by OpenAI, the creator of ChatGPT. Bernt Bornich, the CEO and founder of 1X says that its humanoid robot, EVE, has been active since April this year and marks the first instance in human history where a truly humanoid robot has been successfully integrated into a professional environment.
The company says that EVE can perform nursing and bartending tasks and is currently operational in the U.S. and Europe as a security guard. Then there’s Digit from Agility Robotics, an Oregon-based robotics company.This humanoid robot can unload and load totes (up to 35 pounds) and put them on a conveyor. Amazon is already experimenting with Digit in its warehouses today. Digit uses its claw-like hands to grab and move empty tote boxes. According to Melonee Wise, CTO of Agility, Digit could also handle material replenishment tasks like picking up a box of containers and dumping it into an unscrambler. However, loading several containers by hand into a case would prove more difficult.
“Digit is really good at moving box-like or tote-like containers; that’s Digit’s superpower. It gets trickier when we talk about stacks of things or individual objects that we have to potentially pinch. A lot of Digit’s manipulation is more like tongs, less like bi-manual hands,” says Wise.
Sanctuary AI says that Phoenix is in the pilot stage, yet is ready for real-life application and can learn from demonstration by users wearing a VR headset to “show” the robot a new task. This remote control allows workers to operate the robot from home, decreasing their need to be on site, or from handling the task themselves. Sanctuary demonstrated the potential of robot remote work with a pilot test at a retail store in January where a human guided the robot through 100 tasks.
If a humanoid robot can stand security, make a cocktail, and move totes around, can it package products too? Can it operate an HMI on a packaging machine?
“Not only could Phoenix fill one of those roles, it could be used to perform any and all of them, which is unique,” says Sanctuary AI’s Rose. “Historically, many of the popular and successful robots that we’ve seen over the last several years have been on the special-purpose end of the spectrum. For example, an automated case labeling machine could perform the singular task of labeling boxes repeatedly, but by design these use cases are exclusive. At Sanctuary AI, we’re doing something entirely different — we’re building general-purpose robots that can do any work a person might be reasonably expected to do.”

,It turns out many humanoid robots can handle both changeover and operating an HMI. These general-purpose robots, like Apollo, have the capability to manage the HMI interface (depending on what’s on the screen) and handle changeover, but due to its sophisticated technology, may not need to interface with the HMI like us humans.
“The robot can directly connect to the back end… it doesn’t necessarily need a touchscreen interface like we do because it can just connect to the computer,” says Cardenas.
When I reached out to Melonee Wise of Agility Robotics, she expressed the same idea.
“Most likely Digit would just do it telepathically… Digit would most likely look at a system without even having to look at the touchscreen, and just ask the system and the network it’s connected to. That’s how we do it today,” says Wise.
So, while some humanoids like Phoenix can operate an HMI just like we can, others can simply “talk” to the machine directly and skip the screen altogether.
Future Functionality Is Promising
Today, most of the humanoid robotic companies I spoke with are still in the pilot phase of deployment or are testing use cases with select customers (whom they won’t disclose the names of). Apptronik is currently looking for more companies to partner with to pilot the robots and come up with initial use cases that the company says can then prove out the ROI. Once proved out, the company says its working to scale quickly and in doing so, more robots that can perform more tasks will be available in the near term. Cardenas has been quoted saying that full production is slated for the end of 2024.
“We’re at the entry point now, but these robots will get better and better over time. As one is learning on a specific task, the whole fleet is improving over time. The industry will improve dramatically over the next 3-5 years,” says Cardenas.
Wise says that Agility is partnering with customers, doing “pilots that are transitioning to POs.” She says that while she can’t talk about specific customers right now, there are “POs in play.”
Now, the company is working with customers to get Digit out into more manufacturing facilities, in addition to Amazon, to fill automation gaps and manufacturing challenges. The company has shown that Digit can unload and load totes and put them on a conveyor to help bridge automation gaps between what Wise describes as “islands of automation.” These humanoids can take over where manual labor is required, for example, in between the islands of automation spread out throughout a plant.
“The mixture of mobility and manipulation is very powerful,” says Wise.
The company is exploring palletizing/depalletizing tasks for Digit in the future, but for now Digit’s superpower remains loading and unloading totes.
“Our focus is in machine-assisted tote unload and load… that tends to be cross-cutting across verticals from e-commerce, logistics, and manufacturing,” says Wise.
Robots as a Labor Solution
So, what’s driving adoption of humanoids in the workplace? Experts agree that the number one motivator is labor shortages, followed by the desire to remove ergonomically challenging tasks off human workers.
“It comes down to the labor gap. You’ve got about a million jobs unfilled in logistics, material handling, manufacturing. And when we talk to customers, their big pain point is that 1 in 3 people don’t show up for a shift, and they have 20 open jobs… they just need to get the work done,” says Wise.
“We see a massive opportunity here given there’s such a clear need for labor in manufacturing,” says Sanctuary AI’s Rose. “At the onset of the pandemic, the manufacturing industry lost roughly 1.4 million jobs and currently has around 700,000 job openings, representing 7% of the overall 9.9 million job vacancies in the U.S. Our robots are designed to help address labor shortages across industries, including manufacturing and packaging, as well as take on roles that are boring or unsafe for people.”
Removing dangerous tasks and filling the labor gap is one thing, but then there’s increasing throughput. Since robots can perform strenuous or repetitive tasks longer than humans, without the need for a break, Wise says that general throughput of humanoid robots is higher than that of human workers. But there is the issue of battery life and charge time. While some companies I researched reports four hours of battery life, Digit lasts about two hours depending on what Digit is doing, and it takes about one hour to charge. Agility says that it is working on improving the battery life, but also pointed out that typically, companies deploy a fleet of Digits so while one is charging, others are working.
Are Humanoid Robots the Future of Packaging?
The functionality and capabilities are clearly there for humanoids to be deployed successfully in various places along the packaging line and the evidence supports that they can help solve today’s workforce issues and provide automated labor where needed.
So, the final question is this. Is there a future where humanoid robots are used more and more in packaging facilities? While not too surprisingly, the robot manufacturers are more optimistic about this future than the CPGs I spoke with.
“The idea of using humanoid robots in the packaging facilities has not crossed my mind but humanoid robots do present good opportunity,” says Daniela Garcia, a packaging engineer in the dairy industry. “They have potential for implementation in areas where repetitive motions that cause fatigue over time are common. My mind goes to the loading of case packer magazines or the general replenishing of materials for equipment that is manually loaded today. Although this is the initial thought, such implementation requires thorough understanding of the limits and capabilities of humanoid robots.”
Camron Franklin, senior parcel account manager, Conveyor Solutions, agrees that there is value in taking repetitive motions off human workers, but the question on everybody’s mind is cost.
Many robot manufacturers like Sanctuary AI and Apptronik will be deploying their robots through a Robotics-as-a-Service (RaaS) model where customers can lease the robots for an ongoing fee. Pricing varies based on the size of the operation and complexity of the tasks being performed and companies I spoke with are not eager to give out exact numbers. Even a Google search won’t net you exact numbers on humanoid robot pricing.
Cardenas from Apptronik says that deploying them as RaaS is meant to offer the robots at a price comparable with the “rates of existing workers” by offering them at a “salaried” rate.
“The target is, long-term, to produce a system that costs less than $50,000 per year—and what that does is open up the range of different opportunities, but we’re not there yet today. That’s the goal, and that’s part of the design of Apollo to enable that,” says Cardenas.
Robots-as-service is helpful for companies and allows them to try the robots out and learn their capabilities, without a large up-front investment.
Right now, Agility is selling Digit CapX plus Saas, but will go to a RaaS model in the future. According to Wise, as expected, the robots are “pretty expensive,” and she cannot publicly talk about price at this time.
What about repair and maintenance? Apptronik says that right now it is doing all its own service and maintenance but is looking to partner with third party providers that are already doing a lot of maintenance for other automation systems at scale. But general-purpose robots like Apollo and Digit are created to be easy to maintain.
“One of the keys for a robot like Apollo is for it to be easy to maintain, easy to swap out parts, and modularity is a big focus for us as we move ahead to enable that,” says Cardenas.
Wise also says Digit was created to easily change out parts on the robots, simplifying maintenance and service. But what about TCO (total cost of ownership) or ROI?
“Based on a 10-hr, two-shift operation that runs 5-6 days a week, we can achieve a payback, or ROI, of less than two years,” says Wise.
If labor shortages continue, and robot prices decrease, a robotic humanoid future becomes a little more plausible. While exactly what humanoid robot adoption will look like remains to be seen, the interviews I conducted helped me to realize a not-so-far-off future where these robots can fill in gaps along the packaging line. “I think higher robotic use in inevitable, but the use case for something like this would need to be for a very large organization,” says Matthew Lebo, Director of Operations at Kroma Wellness, a superfoods and wellness brand. “That said, further robotic adoption is likely going to happen. Will it look exactly like that, it's hard to say.
We’re clearly in the early days for general purpose robots as most are not yet available for purchase, or hire, in large quantities, or with the exact skillset CPGs may be looking for. But these robotics companies are working hard on the technology to get them ready for scale and improve functionality in manufacturing, logistics, and even packaging.
As with all trends and new technology, time will have to tell us how broadly this will be adopted and in what capacity.
