Standard Practice for Lower Extremity Exoskeleton Locomotion Transitions

Importancia y uso:

5.1 Exoskeletons may be used in several domains, including for example, industrial, military, first-response, medical, and recreational, to provide potential benefits in supporting user capability, as well as the potential to prevent injury. Exoskeletons may be required to traverse objects, such as stairs and ramps, in unstructured, complex environments.

5.2 All course configurations and recommended apparatus should be in compliance with the following safety standards: Americans with Disabilities Act (ADA), Architectural Graphic Standards (2), International Building Code, and Occupational Safety and Health Administration (OSHA) Regulations. However, not all stairs, ramps, and cross-slopes will meet these criteria as they arise from unstructured natural elevation changes (for example, hills, mountains), or are in buildings that do not meet current standards. If the operational environment of interest requires usage in these environments, care must be taken to ensure test safety. For all artifacts selected, dimensions should be documented, as noted on the test report (see Section 12). Tables provided in 5.2.1 – 5.2.3 are summarized from the ADA and OSHA references showing maximum and minimum values.

5.2.1 A summary of standard stair measurements is provided in Table 1.

5.2.2 A summary of standard ramp measurements is provided in Table 2.

5.2.3 A summary of standard cross-slope measurement is provided in Table 3.

5.3 The apparatus is recommended to be modular such that they can be arranged into different course configurations to facilitate exoskeleton assessment in multiple scenarios based on test requestor and user requirements. The standard course configurations include four configurations (see Section 6) designed for a range of needs, including traversing common situations and density of transitions.
