This paper delves into the concept of embodiment in AI, discussing the relationship between a system's body, experience, and intelligence. It challenges the notion that physical bodies are essential for AI, emphasizing the significance of sensorimotor experience and design principles. The role of human-like experience in behavior and intelligence is explored, highlighting the importance of experience-grounded AI models. The study also addresses the implications of simulating non-human experiences for AI systems.

Embodiment: Does a laptop have a body? Pei WangTemple University Philadelphia, USA
Embodiment Different interpretations: • Give the system a body • Give the system a human-like body • Let the system behave according to its experience • Let the system behave according to its sensorimotor experience
Body and experience • As far as a system is implemented, it has a body • As far as a system interacts with its environment, it has sensors and actuators • “Experience” is the stream of input information, that stretches in time • Experience depends on body
Disembodiment • A laptop has a body, as well as experience • Its experience comes through some sensorimotor device, though may be described abstractly • Disembodiment of traditional symbolic AI comes from over-idealizing environment and ignoring experience
Experience-grounded • Open to unexpected and uncertain experience, and respond in real-time • Decide the meaning of a symbol by its experienced relations with other things • Decide the truth-value of a statement by the evidence collected from experience • Decide the solution to a problem according to available knowledge
Difference in experience • Human-like experience is necessary for human-like behavior, though not for intelligence in general • “Intelligence” is not defined by behavior, but by experience-behavior relationship • Though there are practical reasons to simulate human experience, an AI can have non-human experience (and therefore, non-human behavior)
Conclusions • “Embodiment” is necessary for AI when it is interpreted as “experience-grounded” • Whether a system is “embodied” is not determined by its body, but by its design principle • To simulate human sensorimotor experience has important values, but is not necessary for every AI system
