mc-stop_skill

Overview

This skill stops all movement and cancels any embodied motion immediately. It is designed as a critical safety tool for emergency stops, interrupts, and reflection pauses. Use it whenever motion must be halted without delay to prevent harm or to allow safe replanning.

How this skill works

When invoked, the skill issues an immediate stop command to the motion controller and cancels any queued or ongoing movement operations. It returns a machine-readable result with a boolean success flag and a short acknowledgement message. The input is ignored; the call is treated as an unconditional interrupt.

When to use it

• Emergency stop when motion could cause harm or damage
• Interrupt ongoing actions before replanning or reflection pauses
• Cancel unintended or unsafe movement detected by sensors
• As a safety precaution when system state is uncertain
• During testing to quickly halt all motion without additional logic

Best practices

• Invoke liberally when safety is a concern; stopping is low-risk
• Follow stops with state inspection and a controlled replan before resuming
• Combine with logging and alerts so the stop event is recorded and visible
• Ensure higher-level logic checks success flag before proceeding
• Use in watchdogs or anomaly detectors to enforce safe behavior

Example use cases

• Immediate halt when a collision is imminent
• Pause movement for sensor recalibration or environment scan
• Abort a motion sequence if a human operator triggers an emergency
• Stop all actuators before switching control modes
• Use in test harnesses to reset motion state between scenarios
