The year 2025 continues to bloom in modernity, with several industries leaning toward the integration of collaborative robots, or cobots. By changing the weight of the labor, cobots are providing human workers with more streamlined operations, reduced errors, and improved overall efficiency. And as industries move toward smart manufacturing and Industry 4.0, human-robot collaboration is becoming a key driver of innovation and competitiveness.
But as industries progress into this evolution, cobots can still pose risks despite built-in safety features if not properly integrated, maintained, or monitored, which is why risk assessments and proper training are essential to ensure safe and efficient collaboration on the factory floor.
Key Benefits of Cobots
It’s undeniable that cobots are reshaping manufacturing by building a new form of synergy between humans and machines. And because they are a lot different from traditional robots that are confined to cages, they progressively bring several operational and strategic advantages:
-
Increased Productivity: Cobots automate repetitive or precision-heavy tasks, enabling faster throughput while freeing human workers for higher-level responsibilities.
-
Task Flexibility: Cobots are easily reprogrammable and adaptable to a wide range of applications, from assembly and welding to inspection and packaging, making them ideal for high-mix, low-volume production.
-
Lower Costs and Faster ROI: Cobots generally cost less than traditional industrial robots, and with intuitive interfaces and fewer infrastructure requirements, they also minimize production interruptions.
Cobot Safety Stats
Collaborative robots (cobots) are engineered with safety in mind and are equipped with force-limiting mechanisms, proximity sensors, and programmed behavior restrictions. However, real-world deployment presents complex challenges. Safety is not guaranteed by design alone; it must be supported by contextual awareness, human behavior, task variability, and continuous oversight.
A review of Severe Injury Reports (SIRs) from the U.S. Occupational Safety and Health Administration (OSHA) reveals 77 robot-related accidents from 2015-2022. Of these, 54 accidents involve stationary robots, resulting in 66 injuries, mainly finger amputations and fractures to the head and torso. Mobile robots caused 23 accidents, leading to 27 injuries, mainly fractures to the legs and feet.
In order to uncover recurring hazard patterns, a two-stage deductive–inductive thematic analysis was performed using text data from the final narratives in the reports. The findings, as OSHA reports, include precipitating mechanisms such as unexpected robot movement during maintenance or setup, sensor misreads, or improper environmental calibration. Other contributing patterns that were discovered: operator complacency due to perceived safety, incomplete training on cobot behavior and limits, or poor integration between robotic systems and human workflows.
The true benefit of cobots lies in their ability to reduce ergonomic strain and promote flexible manufacturing. But, this potential can only be realized when safety is treated as an evolving practice, not a one-time checklist.

University of Groningen Study – Mental Strain in Human-Robot Collaboration
This research highlighted the psychological impacts of working alongside robots. Findings indicate that while robots can alleviate physical strain, they may increase mental fatigue and reduce job satisfaction due to factors like monotonous tasks and reduced autonomy.
While these studies do not declare a crisis, they collectively warn that efficiency is not automatic and actively present a conditional future that hinges on how cobots are integrated into workplaces.
Roberta Nelson Shea, the Global Technical Compliance Officer at Universal Robots, emphasizes that while cobots are designed with safety in mind, they are not inherently safe for every application. Each deployment requires a thorough risk assessment to ensure safety. She states:
“You will still need to do a proper risk assessment and perform risk mitigation on the factory floor before deployment.”
This highlights the importance of not assuming safety based solely on the collaborative nature of the robot, but ensuring that all aspects of the specific application are evaluated for potential hazards.
The Path to a Successful Collaboration
Without a doubt, cobots are able to represent a transformative force in manufacturing. But with its growth, industries and manufacturers must continue to address underlying issues that may cause several employees’ distress, or even worse, their safety.
If employed within the workplace without strategic implementation and updated safety protocols, instead of resolving existing issues, these cobots may just worsen them. This new era demands not just machines that collaborate, but systems that evolve with them, balancing efficiency with human-centered design and safety.
Long-term success also relies on creating systems where workers can give feedback on how cobots behave and perform tasks. This can help cobots, such as the ones shown in the image below, to improve continuously.
There are several points manufacturers should consider in aiming for a successful collaboration:
Conduct a Thorough Risk Assessment
Before cobots are deployed, manufacturers must evaluate potential hazards specific to the task, environment, and human interaction, such as repetitive motion, floor conditions, or lighting.
Design Safety into the System
Engineers should implement force and speed limits using built-in cobot features. To reduce injury risk in the event of contact, surfaces should be rounded and made with soft padding and lightweight materials. Adding safety-rated end effectors specifically for human-robot interaction can also be beneficial.
Use Protective Measures and Devices
Depending on the level of risk, manufacturers should implement appropriate protective strategies, like safety-rated monitored stops when humans enter shared workspaces, power and force limiting (PFL) features to automatically reduce force upon impact, proximity sensors, laser scanners, or light curtains to detect and react to human presence, and emergency stop buttons that are easily accessible near all work zones.
Follow International Safety Standards
Compliance with relevant standards, such as the ISO 10218-1 / 10218-2 for general robot safety requirements and ISO/TS 15066, which is specific to collaborative robot applications, including force/pressure thresholds, ensures legal and practical safety compliance.
Train Employees and Operators
Even the safest cobots require well-trained personnel, so it is highly recommended that the staff who will be working closely with them are properly trained about the machine’s behavior, safe operating zones, and emergency procedures. Emphasizing awareness of cobot motion patterns and how to intervene safely will also help with the precaution.
Regular Inspection, Maintenance & Updates
To sustain long-term safety, it is best to schedule routine inspections of cobots, sensors, and emergency systems. Keep software and firmware updated to address any safety-related bugs. And, reassess risks if tasks, environments, or operators change.
Continuous evaluation, ethical deployment, and a steadfast commitment that is focused on the safety of the workers are non-negotiable. The promise of human-cobot collaboration can only be fulfilled if innovation is matched with responsibility, where people remain at the core of progress, not overshadowed by it. In this light, the future is not a crisis waiting to unfold, but an opportunity to redefine what safe, smart, and ethical automation looks like.
