Application

Design takeaway

Designers of artificial hands should adopt standardized assessment protocols like AHAP to objectively measure and compare their designs against human capabilities and other artificial systems.

How to apply

When designing or evaluating robotic grippers or prosthetic hands, use a standardized set of objects and grasp types to generate objective performance metrics.

Project actions

  • 01When evaluating a design, consider how you can measure its performance objectively.
  • 02Look for existing standardized tests or protocols in your design domain.

Method & Evidence

AimTo develop and validate an objective protocol for quantifying the grasping ability of anthropomorphic artificial hands.
MethodDevelopment and application of a standardized assessment protocol.
ProcedureThe Anthropomorphic Hand Assessment Protocol (AHAP) was created, incorporating 26 grasp postures/tasks based on eight human grasp types and two non-grasping postures, using 25 standardized objects. The protocol quantifies grasping ability through a numerical Grasping Ability Score (GAS) and was tested on different artificial hand designs to demonstrate its effectiveness in evaluating improvements in grasping surface, force, and kinematics.
ContextRobotics and Prosthetics

Variables

IVArtificial hand design (e.g., different configurations, specific hand models).
DVGrasping Ability Score (GAS), success rate of grasps, force applied, kinematic data.
CVObject set, defined grasp types/postures, testing environment.

Strengths & Limitations

Strengths

  • +Provides a quantifiable and objective measure for hand performance.
  • +Uses a standardized set of objects and tasks for replicability.

Limitations

The objects used might not represent all possible real-world scenarios, and the definition of a 'successful' grasp can be subjective.

Reliability & validity

The study statistically analyzed the reliability, consistency, and responsiveness of the benchmark, indicating its robustness as a measurement tool.

Think critically

How might the selection of objects and grasp types in an assessment protocol inadvertently bias the results towards certain hand designs?

05

Design Principles

"Objective, quantifiable assessment is crucial for the iterative improvement and comparative evaluation of anthropomorphic robotic and prosthetic components."

This research addresses a critical gap in the development of robotic and prosthetic hands by establishing a standardized method for performance evaluation. Such a protocol is essential for driving innovation, enabling direct comparison between different designs, and ultimately leading to more functional and human-like artificial hands.

06

What This Means for Your Design

Researchers have created a test to see how well artificial hands can grab things, giving them a score so people can compare different hand designs fairly.

How to use in your project

  • 1.Reference this study when discussing the need for objective performance metrics in your design project.
  • 2.Use the concept of a standardized protocol to justify your own testing methodology.
