What key is depressed to switch between the different jog methods?

The correct answer is the key that allows operators to toggle between various jog methods, specifically the COORD key. This key plays a crucial role in controlling how the robot moves in relation to its coordinate system. When the COORD key is activated, it enables the user to shift between different coordinate jog modes, such as joint or Cartesian movement. This flexibility is vital for tasks that require precision and adaptability in robot positioning.

While the other keys serve important functions, they do not specifically control the jog method switch. The JOINT key is typically used to jog the robot in individual joint movements, allowing for fine-tuned adjustments on a joint-by-joint basis. The SPEED key adjusts the movement speed of the robot but does not influence the jog methods directly. The MODE key might be used to change the overall operational mode of the robot or system but does not specifically address the switching of jog methods. Therefore, the COORD key is essential for navigating among the distinct jog methods effectively.
