Self-Schemas

Self-Schemas

In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Stereotype Content Model

Stereotype Content Model

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence categorization, a person will feel...

Hierarchy of Motor Control

Hierarchy of Motor Control

The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Understanding the Self

Understanding the Self

The self is a central aspect of human identity, encompassing an individual’s beliefs, emotions, perceptions, and experiences. It is a cognitive and psychological construct that enables individuals to interpret their traits and behaviors, influencing how they perceive themselves and interact with the world. While personality consists of stable and enduring characteristics, the self is shaped by self-perception and social experiences. This distinction highlights the dynamic nature of the self,...

Understanding Self-Concept

Understanding Self-Concept

The self-concept encompasses individuals' beliefs about themselves, structured through cognitive frameworks known as self-schemas. These schemas function as mental representations of specific traits or behaviors, influencing how self-relevant information is perceived, processed, and remembered. For example, individuals who are schematic for body weight are more likely to interpret routine experiences—such as dining out or shopping—through the lens of that trait. Conversely, those aschematic for...

Area of Science:

Robotics
Computer Vision
Machine Learning

Background:

Robotic manipulators require accurate kinematic models for precise operation.
Learning these models from scratch, especially with self-observation, presents significant challenges.

Purpose of the Study:

To develop a method for robots to learn their kinematic models from scratch using only a monocular camera.
To enable robots to adapt their kinematic models in response to physical changes.

Main Methods:

Utilized a Bayesian network-based approach for flexible kinematic model representation.
Implemented self-observation through a single monocular camera for data acquisition.
Developed mechanisms for monitoring model prediction quality and adapting the model to body changes.

Main Results:

Successfully learned kinematic structures and joint angle-dependent geometrical relationships.
Demonstrated the ability to monitor and adapt the kinematic model based on prediction errors.
Validated the approach on both simulated and real robotic manipulators.

Conclusions:

The proposed approach enables robots to learn and adapt their kinematic models autonomously.
This self-learning capability is crucial for robust robotic manipulation in dynamic environments.
The method shows promise for real-world applications like end-effector pose prediction and control.
