What do you mean, sensors/percepts and effectors/actions?

For Humans
– Sensors: Eyes (vision), ears (hearing), skin (touch), tongue (gestation), nose (olfaction), neuromuscular system (proprioception)
– Percepts:
• At the lowest level – electrical signals from these sensors
• After preprocessing – objects in the visual field (location, textures, colors, …), auditory streams (pitch, loudness, direction), …
– Effectors: limbs, digits, eyes, tongue, …..
– Actions: lift a finger, turn left, walk, run, carry an object, …
The Point: percepts and actions need to be carefully defined, possibly at different levels of abstraction
A more specific example: Automated taxi driving system
• Percepts: Video, sonar, speedometer, odometer, engine sensors, keyboard input, microphone, GPS, …
• Actions: Steer, accelerate, brake, horn, speak/display, …
• Goals: Maintain safety, reach destination, maximize profits (fuel, tire wear), obey laws, provide passenger comfort, …
• Environment: Urban streets, freeways, traffic, pedestrians, weather, customers, …
