What event is triggered when the robot reaches a defined axis limit?

The correct answer is that the robot stops all movements when it reaches a defined axis limit. This safety feature is implemented in robotic systems to prevent damage to the robot, the workpiece, or the surrounding environment. Limits are set to ensure that the robot operates within safe boundaries, and when these limits are exceeded, the robot’s control system automatically halts all motion. This mechanism helps protect the hardware from overextending or experiencing mechanical stress, which could lead to failures or costly repairs.

In the context of robotic operation, the limit switch or sensor detects that the robot has reached its maximum allowable position in a certain direction. By stopping the robot immediately, the system can avoid potential collisions and ensure operational safety.
