The deployment of a collaborative robot is often celebrated for its "plug-and-play" nature, but this ease of use can lead to a dangerous oversight: the assumption that the machine is inherently safe in every configuration. A risk assessment is a legal and functional necessity, yet many manufacturers fall into predictable traps that can compromise worker safety or lead to costly production delays.

Frequent Pitfalls in Safety Planning

One of the most common mistakes is focusing solely on the robot arm rather than the "robot system." A cobot may be power-limited, but if it is programmed to move a sharp metal workpiece at high speeds, the application itself becomes hazardous. Failing to account for the end-of-arm tooling (EOAT) and the specific path of motion is a critical error. To fix this, teams must evaluate the "worst-case scenario" for every movement cycle.

Another oversight is neglecting the "clamping points" or "pinch points" created by the environment. Even if a collaborative robot has sensitive collision detection, a worker’s hand can still be trapped between the robot and a fixed structure like a table or a conveyor belt. Operators should ensure a minimum clearance of 500mm from fixed objects or program the robot to avoid these zones entirely. Finally, many businesses fail to re-evaluate the risk assessment after making minor adjustments to the robot’s task, which can inadvertently introduce new risks.

Precision Safety Solutions with JAKA

At JAKA, we aim to simplify the path to compliance by building advanced safety features directly into our hardware. We understand that a successful deployment requires more than just a stopping mechanism; it requires a robot that is aware of its surroundings. Our engineering team focuses on reducing the complexity of these assessments through intelligent sensing technology.

Specifically, our JAKA S series is designed to address the most rigorous safety requirements. The JAKA S series features a high-performance safety skin—a flexible, tactile sensor that covers the arm to provide 360-degree detection. This allows the cobot to sense an approaching human and stop before an impact occurs, significantly lowering the risk profile of the application. With a payload capacity of up to 18 kg and a repeatability of ±0.03mm, this series ensures that safety does not come at the expense of industrial precision.

By integrating a JAKA system, you benefit from our commitment to "Free Your Hands" safely. Every JAKA collaborative robot is equipped with a visual, graphical interface that makes it easy to define safety planes and restricted zones without deep coding knowledge. This transparency helps safety officers quickly verify that the JAKA unit is operating within the required parameters, ensuring a secure and productive environment for all staff.
