A walker that could help navigate and avoid collisions with obstacles could help reduce health costs and increase the quality of care and independence of thousands of people. This study evaluated the safety and performance of the Veterans Affairs Personal Adaptive Mobility Aid (VA-PAMAID). We performed engineering tests on the VA-PAMAID to determine safety factors, including stability, energy consumption, fatigue life, and sensor and control malfunctions. The VA-PAMAID traveled 10.9 km on a full charge and avoided obstacles while traveling at a speed of up to 1.2 m/s. No failures occurred during static stability, climatic, or fatigue testing. Some problems were encountered during obstacle climbing and sensor and control testing. The VA-PAMAID has good range, has adequate reaction time, and is structurally sound. Clinical trials are planned to compare the device to other low-technical adaptive mobility devices.
一种能够帮助导航并避免与障碍物碰撞的助行器，有助于降低医疗成本，并提高数千人的护理质量和独立性。本研究评估了退伍军人事务部个人自适应移动辅助设备（VA-PAMAID）的安全性和性能。我们对VA-PAMAID进行了工程测试，以确定安全因素，包括稳定性、能耗、疲劳寿命以及传感器和控制故障。VA-PAMAID在充满电的情况下行驶了10.9公里，并在速度高达1.2米/秒时避开了障碍物。在静态稳定性、气候或疲劳测试期间未发生故障。在攀爬障碍物以及传感器和控制测试过程中遇到了一些问题。VA-PAMAID续航能力良好，反应时间充足，结构稳固。计划开展临床试验，将该设备与其他低技术自适应移动设备进行比较。
