How can wait messages be canceled?

Wait messages in robotic systems are designed to pause the operation until a specific condition is met. These messages can be canceled in several ways, but the most effective method in practice is to acknowledge the message. Acknowledgment indicates to the system that the operator is aware of the current operation's status and can either proceed to the next step or cancel it.

Pressing the "simulate" button generally does not cancel the wait message; instead, it may enter a simulated mode where the robot's movements are not executed in real-time, but this does not affect the current status of a wait message. Restarting the robot typically resets the entire program, which not only cancels the wait message but also disrupts other ongoing processes. While entering a new command might influence the state of the robot, it does not guarantee the cancellation of a current wait message.

Thus, acknowledging the message is the proper method for cancelling it, as it explicitly communicates to the robotic system to proceed with operations following the wait condition.
