Soft Robotics for Fall Mitigation: Preliminary Design and Evaluation of a Wearable System using Continuum Robots
crossref(2024)
摘要
Falls can lead to serious consequences such as bone fractures or even death. Various fall protection devices such as mobile walkers, wearable airbags and lower-limb wearable robots have been developed to provide balance support or mitigate the damage from a fall. While these devices have shown promising results, critical drawbacks still exist. Most importantly, current devices can only mitigate the damage to a fall upon occurrence, but cannot take proactive action to prevent it. In this paper, we report on the design and evaluation of a novel fall prevention device using two compliant continuum robots. These two robots, which are pneumatically actuated, will be mounted to the back of a human user and deployed to grasp nearby static objects in the early stages of a fall, detected using onboard sensors. Preliminary fall experiments on a mannequin in forward, backward, and lateral directions demonstrate the efficacy of the proposed design.
