Final answer:
A pressure plate and a microphone can be considered input devices in robotics.
Step-by-step explanation:
In the context of robotics, the two robot components that could be considered input devices are a pressure plate and a microphone.
A pressure plate detects and measures the force or pressure exerted on it. For example, it can be used as an input device in a robot's foot to detect if it steps on an object.
A microphone converts sound waves into electrical signals. It can be used as an input device to allow a robot to listen to commands or detect sounds in its environment.
