wearable robots copiaLower limb wearable robots are entering an exciting era. An increasing number of solutions are moving out of the lab, approaching the everyday rehabilitation practice and home-based assistive scenarios.

In this context, the quantitative assessment of the technology is crucial for its correct inclusion in the market. Nevertheless, the tool normally used to support this process, i.e. benchmarking, hasn’t been formulated yet in the wearable robotics field.

The European projects H2R and Biomot are developing a scheme for the definition of benchmarks specifically designed for wearable robot devices [1]. This scheme takes into account two main perspectives, named “functional” and “interaction” (see figure below). The functional perspective aims at evaluating the stability, efficiency and correctness of motion of the global system constituted by the patient wearing the robot. The interaction perspective aims at evaluating the symbiotic interplay between the user and the device, under the physical, cognitive, and psychophysiological standpoints.

So far, in this website, the benchmarking scheme is only focusing on the “Functional part”, being this sharable across different communities. Nevertheless, future extensions of the scheme should also include aspects specifically devoted to wearable robots.
