In robot programming, how is an emergency stop typically executed?

An emergency stop in robot programming is primarily executed using the emergency stop button. This button is specifically designed for quick activation, allowing operators to immediately halt all robot operations, thereby ensuring safety in potentially hazardous situations. The emergency stop button is strategically placed and easily accessible to provide a rapid response in emergencies, minimizing the risk of injury or damage.

The other choices do not serve the same purpose for an immediate and safe shutdown. The Reset key might be used to clear errors or restart operations, but it is not intended for emergencies. The FCTN key generally serves functions related to programming or operation but lacks the immediate safety feature of an emergency stop. Finally, switching off the power can be a method to stop a robot, yet it is not instant and may not be as safe or practical as using the dedicated emergency stop button.
