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...

Mechanical Efficiency of Real Machines

Mechanical Efficiency of Real Machines

The mechanical efficiency of a machine is a fundamental concept that describes how effectively a machine can convert input work into output work. According to this concept, the efficiency of a machine is equal to the ratio of the output work to the input work. An ideal machine, meaning a machine that has no energy losses, has an efficiency of one. This implies that the input work and the output work are equal.
However, in reality, no machine can be truly ideal, and all of them experience some...

Mechanical Systems

Mechanical Systems

Mechanical systems are analogous to to electrical networks where springs and masses play similar roles to inductors and capacitors, respectively. A viscous damper in mechanical systems functions similarly to a resistor in electrical networks, dissipating energy. The forces acting on a mass in such systems include an applied force in the direction of motion, counteracted by forces from the spring, a viscous damper, and the mass's acceleration. This interplay of forces is mathematically described...

Area of Science:

Robotics
Human-Computer Interaction
Ergonomics

Background:

Collaborative Robots (CoBots) are increasingly used in industrial settings.
Current CoBots primarily offer workspace sharing or non-contact collaboration.
Physical collaboration in high-payload tasks presents a significant opportunity for enhanced worker support.

Purpose of the Study:

To investigate the extent to which robots can assist workers in physical human-robot collaboration (pHRC) tasks.
To evaluate the impact of physical robot assistance on worker biomechanics and effort.
To develop methods for assessing robot reliability and synergistic interaction in collaborative scenarios.

Main Methods:

An interdisciplinary team involving industrial users, ergonomists, biomechanicians, and roboticists was assembled.
Eleven participants performed a repetitive industrial task, both with and without robot assistance.
Biomechanical activity was monitored, and usability/acceptability surveys were administered to participants and industrial workers.

Main Results:

Potvin's method demonstrated a substantial reduction in participants' muscular effort with robot assistance.
A novel method for measuring robot reliability and reproducibility in collaborative settings was developed.
Worker effort and robot power output were found to be in energetic synergy.
Increased worker experience shifted focus from basic functionality to nuanced performance expectations.

Conclusions:

Physical human-robot collaboration is highly beneficial for reducing worker strain in high-payload tasks.
The developed methods provide new insights into robot reliability and synergistic human-robot interaction.
Both participants and industrial workers expressed willingness and perceived usefulness in collaborating with the robot.
