What is the function of the emergency stop button in a robotic system?

The emergency stop button in a robotic system serves the critical function of immediately halting all operations. This feature is essential for ensuring the safety of personnel and equipment. When activated, the emergency stop button sends a signal to the control system to disengage power or stop movement, effectively bringing the machine to a safe and controlled standstill without delay. This rapid response is vital in preventing potential accidents or injuries that could occur if a malfunction or unsafe condition arises during operation.

Other options, such as switching the power on, resuming motion, or initiating diagnostics, do not align with the primary role of the emergency stop button. The emergency stop is specifically designed to stop operations rather than facilitate starting, resuming, or diagnosing issues, reinforcing its importance as a safety feature in robotic systems.
