Final answer:
The limitation of the procedure forward() is that it typically moves an object in a straight line without automatic collision avoidance or path adjustment based on environmental data, which requires additional code to handle complex scenarios.
Step-by-step explanation:
The procedure forward() generally refers to a command in many programming environments and robotics that instructs a robot or graphic object to move forward for a specified distance or time. The limitation of the procedure forward() may vary depending on the context but typically includes the inability to navigate complex paths or handle obstacles without additional logic. For example, in a simple turtle graphics environment, forward() will only make the turtle move in a straight line in the direction it is currently facing. It does not automatically avoid collisions or adjust based on the environment unless additional code is provided. Similarly, in robotics, moving forward without considering sensors or environment data might lead the robot to collide with objects or fail to complete a desired path.
