What is true about Robots?
They operate in the real physical world
Inputs to robots are analog signals in the form of speech waveform or images
They need special hardware with sensors and effectors.
All these options
A device that responds to physical stimuli (such as heat, light, sound, pressure, magnetism, motion, etc.) and transmits the resulting signal or data for providing a measurement, operating a control, or both.
