1. A robotic line kitting system, comprising:
a communication interface; and
a processor coupled to the communication interface and configured to:
receive via the communication interface a signal associated with an unsafe condition;
in response to receiving the signal associated with the unsafe condition, perform a controlled operation to reduce a speed of movement of a robotic instrumentality from an operational speed to a safe speed;
determine that the speed of the movement of the robot instrumentality is at the safe speed; and
in response to the determination that the speed of the movement of the robot instrumentality is at the safe speed, trigger a safety stop by reducing the speed of movement of the robotic instrumentality from the safe speed to zero, wherein the speed of movement of the robotic instrumentality prior to the safety stop is reduced at a first rate from the operational speed to the safe speed and the speed of movement of the robotic instrumentality after the safety stop is triggered is reduced at a second rate from the safe speed to zero, wherein the first rate is less than the second rate.
