In manufacturing, automation is no longer optional—it's essential for tackling severe labor shortages. Yet while large enterprises push ahead with robotics, adoption among small and mid-sized companies (50 employees or fewer) remains at just 32.1%.*

Beyond budget and floor space constraints, there's another barrier keeping factory managers and business owners up at night: the "knowledge gap." The fear that "even if we install a robot, we don't have anyone who can operate it" is a major roadblock to automation.
This article explores how Closer Robotics has shattered that barrier with AI collaborative robots designed for intuitive operation. Discover the technology behind a system that anyone can set up in as little as 3 minutes—zero robotics expertise required.
Why Robot Adoption Stalls on the Factory Floor: The "Too Hard to Operate" Barrier
Large-scale automotive and electronics factories have long relied on industrial robots to achieve high productivity. But for food and cosmetics plants running high-mix, low-volume production, the same approach hasn't worked. One of the biggest reasons: a process called "teaching" that traditional robots require.
What Is "Teaching"—and Why Does It Slow Everything Down?
To operate a conventional industrial robot, you need a specialized control device called a "teach pendant" to program every movement, step by step.
Take palletizing—stacking cartons from a conveyor onto a pallet. To teach a robot this task, you must manually input precise coordinates: the arm's path, the pickup point, the placement position. This requires highly specialized knowledge. Even for a skilled technician or system integrator, a single setup takes around 8 hours.
No In-House Experts, Plus Costly Outsourcing
For high-volume production lines at large companies, this isn't a major issue. Once teaching is complete, the same product runs for months. Keeping a dedicated robotics engineer on staff makes sense.
But in small and mid-sized food factories, high-mix, low-volume production is the norm. Box sizes change between morning and afternoon shifts. Packaging varies by season. Every product change means reconfiguring the robot—and calling in an outside specialist each time, paying premium rates for re-teaching, is neither cost-effective nor practical.
The real barrier to automation in smaller factories? Staff can't easily operate or adjust the robots themselves.
Zero Expertise Needed: The Secret Behind Closer's 3-Minute Setup
Closer Robotics is rewriting the rules of industrial automation. With a philosophy of "software-defined robotics" and "democratizing the user experience," Closer has harnessed AI and software to make robots radically easy to use—so anyone on the floor can operate them, no robotics background required.
The best example of this ease of use: Closer's compact collaborative palletizing robot, Palletizy. It's packed with innovations that eliminate traditional teaching entirely.
1. Intuitive Smartphone-Style Touchscreen
Palletizy's interface uses a clear, intuitive touchscreen display—just like the smartphones your team already uses every day.
Gone are the cluttered buttons and technical jargon of conventional teach pendants. Instead, a simple UI guides users through setup with easy taps. The display is designed for readability, accommodating workers who may struggle with small text. No special training required—staff can master operation on day one.
2. Patented Auto-Layout: Automatic Calculation, Zero Coordinate Entry
The real breakthrough is Closer's patented Auto-Layout function (Patent No. 7665239).
Forget manual coordinate entry. Staff simply input the carton dimensions (length, width, height) and pallet size on the touchscreen. Closer's AI algorithm instantly calculates and generates the most efficient, stable stacking pattern and sequence.
From there, just select the recommended layout and press start. The robot begins operating immediately.
3. Setup Complete in as Little as 3 Minutes
With Auto-Layout, what once took a skilled technician 8 hours now takes a complete beginner just 3 minutes.
Before starting, staff can preview the stacking layout in 3D on the touchscreen—seeing exactly how cartons will be placed, in what order. This visual confirmation builds confidence and lets the team start production with peace of mind.
Real-World Benefits: What Ease of Use Means for the Factory Floor

Dramatically improved usability delivers benefits far beyond "we automated a task."
Flexible Adaptation to High-Mix, Low-Volume Production
With setup changes taking just 3 minutes, Palletizy excels in high-mix, low-volume environments.
A single robot can handle multiple carton sizes on the same line, switching between them flexibly. When products change, floor staff can adjust settings themselves via the touchscreen—minimizing downtime and eliminating the cost of calling in outside specialists.
From the Floor: Tenkei Seika's Experience
Feedback from factories using Closer's robots highlights the ease of use.
Tenkei Seika Co., Ltd., a market leader in semi-fresh confectionery, installed two compact collaborative palletizing robots on an existing tight production line to automate heavy carton stacking.
Here's what their floor supervisor had to say:
"After just one explanation, I was able to set it up without much trouble. The 3D preview made it easy to understand—it was simple and worked great."
Concerns about "robots being too hard to operate" were quickly put to rest. Intuitive touchscreen controls and 3D visualization helped the system blend seamlessly into daily operations.

Continuous Evolution Through Software Updates
Another key advantage: Closer's robots improve over time. While the hardware stays the same, software updates continuously add new features and enhanced usability. Just like a smartphone, the robot keeps getting smarter and easier to use—shaped by real feedback from the factory floor.
Summary: Democratizing Usability — A Future Where Anyone Can Use Robots
Japan's labor supply is heading toward a cliff. Supply will drop sharply in 2027, with a projected shortage of 11 million workers by 2040. To navigate this crisis, the shift to "let robots handle the hard work, so people can focus on higher-value tasks" isn't just for large enterprises—it's essential for small and mid-sized operations everywhere.
Closer Robotics has eliminated the biggest bottleneck—"robots are too hard to operate"—through the power of AI and software.
- No need to call in expensive specialists.
- No complex programming to learn.
- If your staff can use a smartphone, they can run the robot in 3 minutes.
The era of giving up on automation because "we don't have anyone who knows robots" is over.
To reduce heavy labor, boost productivity, and build a workplace where employees stay healthy and work longer—consider starting small with Closer's AI robots. No expertise required.
