Robots as Powerful Allies for the Study of Embodied Cognition from the Bottom Up
Matej Hoffmann, Rolf Pfeifer

TL;DR
This paper advocates for using robots as investigative tools to understand embodied cognition, emphasizing a developmental approach from basic behaviors to human-like cognition, and highlights mutual benefits for robotics and cognitive science.
Contribution
It introduces a bottom-up robotic approach to studying embodied cognition, systematically exploring stages from reflexes to human-like thinking, and discusses reciprocal benefits for robotics and cognitive science.
Findings
Robots enable systematic manipulation of embodiment variables.
Developmental stages from reflexes to cognition can be studied robotically.
Robots benefit from human-like cognition for autonomy and resilience.
Abstract
A large body of compelling evidence has been accumulated demonstrating that embodiment - the agent's physical setup, including its shape, materials, sensors and actuators - is constitutive for any form of cognition and as a consequence, models of cognition need to be embodied. In contrast to methods from empirical sciences to study cognition, robots can be freely manipulated and virtually all key variables of their embodiment and control programs can be systematically varied. As such, they provide an extremely powerful tool of investigation. We present a robotic bottom-up or developmental approach, focusing on three stages: (a) low-level behaviors like walking and reflexes, (b) learning regularities in sensorimotor spaces, and (c) human-like cognition. We also show that robotic based research is not only a productive path to deepening our understanding of cognition, but that robots can…
