Perception

Perception

Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

Tactile and Chemical Senses

Tactile and Chemical Senses

Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

Observational Learning

Observational Learning

Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Background:

Dexterous robotic grasping in non-visual settings is challenging due to object diversity.
Adaptive force modulation and tactile feedback are crucial for manipulation.
Current methods often rely on visual input or predefined object models.

Purpose of the Study:

To develop a Reinforcement Learning-Based Multimodal Perception (RLMP) framework for non-visual robotic grasping.
To integrate human-like grasping intuition with tactile-guided reinforcement learning.
To enable robots to grasp diverse objects reliably without visual data.

Main Methods:

Proposed the Reinforcement Learning-Based Multimodal Perception (RLMP) framework.
Developed a Tactile-Driven Deep Convolutional Neural Network (DCNN) for object recognition using tactile data.
Implemented a reinforcement learning (RL) policy refinement mechanism correlating finger kinematics with tactile feedback.

Main Results:

Achieved 98.5% object recognition accuracy using spatiotemporal pressure patterns with the Tactile-Driven DCNN.
Demonstrated reliable grasping of both deformable and rigid objects.
Maintained force precision crucial for handling fragile targets.

Conclusions:

The RLMP framework enables dexterous robotic grasping in non-visual environments.
