Performance Evaluation of Lower Limb Exoskeletons: A Systematic Review
Summary
Developing standardized benchmarks for wearable robots is crucial for product translation. Current lower limb exoskeleton evaluations primarily focus on walking, neglecting daily activities and human-robot interaction metrics.
Area of Science:
- Robotics
- Biomechanics
- Human-Computer Interaction
Background:
- Wearable robots, particularly lower limb exoskeletons, lack standardized benchmarking methodologies, hindering research-to-product translation.
- A growing body of research quantifies exoskeleton performance, but methods, variables, and protocols are highly heterogeneous.
- This heterogeneity complicates the comparison and adoption of robotic exoskeleton technologies.
Purpose of the Study:
- To systematically review and organize existing performance quantification methods for lower limb exoskeletons.
- To identify key performance indicators suitable for developing practical and standardized benchmarks.
- To address the limitations in current evaluation protocols for robot-assisted locomotion.
Main Methods:
- Comprehensive literature review focusing on lower limb exoskeleton performance evaluation.
- Analysis of motor skills and performance indicators across diverse studies.
- Identification of trends and biases in current benchmarking approaches.
Main Results:
- Exoskeleton evaluations are predominantly centered on straight-line walking, with insufficient coverage of activities of daily living (ADLs).
- There is a notable bias towards generic kinematic and kinetic indicators over human-robot interaction (HRI) metrics.
- Current methodologies lack the breadth to capture the full functional capabilities of lower limb exoskeletons.
Conclusions:
- A significant gap exists in the benchmarking of lower limb exoskeletons, particularly concerning ADLs and HRI.
- Standardized benchmarks are needed to facilitate the efficient translation of research prototypes into viable products.
- Future research should focus on developing comprehensive metrics encompassing diverse motor skills and interaction dynamics for robust exoskeleton assessment.
