Avoiding Robot Singularity: 9 Effective Strategies to Maintain Control over Robots
Introduction:
Robot singularity avoidance is crucial in industrial robotics to maintain control over robots and prevent unpredictable or dangerous behavior. Singularities can impact productivity and quality, especially when it comes to tasks like painting. Fortunately, there are several strategies for avoiding the negative effects of singularities in industrial robot programming. These strategies include adding an offset to the robot’s tool, programming the robot to stop near a singularity, moving the robot’s task to avoid singularities, using cuspidal robots that are designed to be singularity-free, imposing joint limits in programming, learning to recognize singularities, becoming a “singularity master” to understand and avoid singularities, adding dynamic singularity avoidance to programming, and using software with automatic singularity detection like RoboDK. By implementing these strategies, programmers can ensure safe and efficient robot movements.

Robot singularity avoidance is crucial for controlling industrial robots and ensuring their safe and predictable movements. Singularities occur when a robot’s control algorithms break down, causing unpredictable or dangerous behavior. To avoid these negative effects, there are several strategies that robot programmers and users can employ.
1. Add an Offset: By adding a small angle to the robot’s tool, the likelihood of axes aligning and creating singularity situations is reduced. However, this strategy may introduce inaccuracies or complications due to the added offset.
2. Stop the Robot: Another method is to program the robot to stop when it nears a singularity. This prevents any potential damage or unpredictable behavior. However, this solution can be inelegant and confusing for users who did not program the robot themselves.
3. Move the Task: A more elegant solution involves moving the robot’s task to another area in its work envelope where singularity is less likely to occur. This requires an understanding of robot kinematics and reachability. Reachability analysis tools like RoboDK can help in identifying suitable spaces in the robot’s workspace.
4. Use Cuspidal Robots: Cuspidal robots are designed to have no singularities, allowing for smooth and safe execution of complex motions. However, these robots may struggle with simple moves and have less precise motions due to the programming techniques used.
5. Impose Joint Limits: Imposing joint limits in robot programming can effectively avoid certain singularities. However, this restricts the robot’s motion and removes a section of its workspace, which may not be suitable for all tasks.
6. Learn to Recognize Singularities: Developing the ability to recognize and identify robot singularities is highly recommended. This knowledge allows for better problem-solving and avoidance of singularities in robot programs.
7. Become a Singularity Master: For those aiming to become robotics experts, gaining a deep understanding of the mathematical concepts behind singularities is recommended. This enables the creation of robot programs that can effectively detect and avoid singularities.
8. Add Dynamic Singularity Avoidance: Dynamic singularity avoidance involves adjusting the robot’s movements on-the-fly when encountering a singularity. This strategy is useful for tasks that involve physical human-robot collaboration, as it ensures the robot avoids touching the human operator.
9. Use Software with Automatic Singularity Detection: One of the most effective ways to avoid singularities is to use robot programming software with built-in automatic singularity detection. This feature, such as the one offered by RoboDK, simplifies programming by notifying users if a trajectory would pass through a singularity.
By implementing these strategies, robot users can ensure that their programs are free from problematic singularities. The ability to recognize and avoid singularities improves the stability and efficiency of robot movements.
Summary: Avoiding Robot Singularity: 9 Effective Strategies to Maintain Control over Robots
Robot singularity avoidance is crucial for controlling industrial robots and ensuring productivity and quality. Singularities occur when a robot’s control algorithms fail, leading to unpredictable and potentially dangerous behavior. To avoid these issues, there are several strategies that can be employed. These include adding an offset to the robot’s tool, stopping the robot when it nears a singularity, moving the task to another area, using cuspidal robots, imposing joint limits, learning to recognize singularities, becoming a “singularity master” by understanding the complex mathematical concepts behind singularities, adding dynamic singularity avoidance, and using software with automatic singularity detection. By implementing these strategies, robot programmers can create safer and more efficient robot programs.
