In the field of collaborative robotics, there's a growing trend where robots are taking on increasingly autonomous decision-making roles. This evolution raises the question of where to draw the line: how far can we delegate critical choices to systems that lack consciousness or moral judgment? Some argue that AI integrated into cobots can optimize safety and efficiency, while others fear a loss of control and unforeseen scenarios. What safeguards do you prefer? Do you think current regulations are sufficient, or should we rethink the governance of autonomous decisions? I'm interested in your views.
Collaborative robotics: How much decision-making should we entrust to autonomous machines?

During my recent internship in a collaborative robotics lab, I worked on a cobot tasked with sorting parts based on their shape. Initially, it was only given movement instructions, but once the AI software was integrated, the robot could decide to reorient a part if it detected a geometric anomaly. To prevent the system from making overly risky decisions (such as pushing a fragile part that might break), we implemented three safeguards: a minimum confidence threshold (≥95% probability before any modification), a chain-of-command validation where an operator approves decisions beyond a certain criticality level, and a real-time tracking log that triggers an alert if the robot deviates from the initial plan by more than 5% in a minute. This combination of quantitative thresholds, human oversight, and traceability kept control while leveraging AI’s efficiency.
Based on this experience, I believe current regulations are still too vague: they need to specify not just the required confidence level but also mandate that manufacturers provide a clearly documented "fallback" human mechanism. Without these requirements, we risk accelerating cobot adoption without ensuring true moral or operational safety.
After testing several cobots in my workshop, the safest way to maintain control while still benefiting from autonomy is to set up a "supervision mode" where the robot can make decisions about trajectory and speed adjustments, but it must always request validation before any action that involves human contact or a mechanical configuration change. Specifically, I integrated a safety relay that cuts off movement if the robot exceeds a force threshold—around 30 N in my case—and programmed a logic that automatically sends the status back to the PLC so the operator can accept or reject the action via a small HMI button. This dual-level system (physical threshold + software validation) reduced unexpected stops by 15% while maintaining smooth operation.
In practice, I also recommend not relying solely on ISO 10218 or ISO 15066 standards; they should be supplemented with a monthly internal audit to verify that every decision scenario has a clearly documented "fallback" for human intervention. Even if current regulations don’t require this redundancy, it’s better to implement it now—a simple, timestamped decision log stored on a secure server provides the necessary traceability to prove the machine never crossed unauthorized limits. This is a practical safeguard that’s easy to deploy, even on a limited budget.
