Study Notes

Stepping Reflex and Development

Infants exhibit stepping movements in early months, which then disappear during a non-stepping window.
Stepping reappears around 11 months when infants begin walking.
Traditional view attributes the U-shaped trajectory to reflexive movements inhibited by cortical maturation, lacking voluntary control.
Thelen and Smith's studies suggest that stepping is influenced by environmental conditions rather than just cortical development.
Stepping can be induced by warm water suspension or treadmill locomotion during the non-stepping window.
Small weights on an infant's ankle can inhibit stepping before the non-stepping window begins.
Factors influencing stepping include leg fat, muscle strength, gravity, and inertia, not merely motor commands from the cortex.

Situated Cognition

Situated cognition theorists advocate for a dynamical systems approach to robotics.
Emphasize starting with simple, ecologically valid problems, such as insect behaviors.
Insects like crickets demonstrate "natural intelligence" through direct sensory to motor connections.
Crickets locate mates by moving towards the sound without complex identification or calculation mechanisms.
Barbara Webb's biorobotics uses insect models to create robots that mimic such behaviors without traditional cognitive systems.

Behavior-Based Robots

Behavior-based robots do not rely on central planning systems like symbolic architectures.
Example: TOTO robot navigates using a topological map to find the shortest route by connecting landmarks, rather than measuring distances.
Bees exhibit similar behaviors in identifying shortcuts between feeding sites.

Situated vs. Embodied Cognition

Situated robots are embedded in their environments, responding to real-time sensory inputs.
Embodied robots have physical bodies and directly engage with the world through physical interactions.
Example: An airline reservation system is situated but lacks embodiment.
An assembly line robot that spray paints is considered embodied but does not adaptively interact with its surroundings.
