Resource constraints are common in prosthetic device research, and research and development inevitably occurs simultaneously. Managing the balance between device upgrades, repairs, and ensuring reliability for participant use present a continuous challenge. This paper introduces an automated robustness testing protocol designed to assess device performance and reliability. The protocol was designed to validate software updates, identify issues, and ensure consistency across prototypes and repairs. We used this method to test new design and software iterations to an active leg system. The protocol was used to successfully identify and address potential issues before participant sessions including deviations in sensors, disconnecting wires, and software bugs. It was also used to demonstrate consistency in mechanical responses across multiple prototypes of the active leg system. Our results show that this method has the capability to identify potential issues before participant sessions, ensuring smoother research workflows and minimizing disruptions during participant use.
资源限制在假肢设备研究中很常见，而且研发不可避免地会同时进行。在设备升级、维修以及确保参与者使用的可靠性之间进行平衡是一项持续的挑战。本文介绍了一种旨在评估设备性能和可靠性的自动化稳健性测试协议。该协议旨在验证软件更新、识别问题并确保原型和维修之间的一致性。我们使用这种方法对一个主动腿系统的新设计和软件迭代进行测试。该协议用于在参与者测试之前成功识别并解决潜在问题，包括传感器偏差、电线断开和软件错误。它还用于证明主动腿系统多个原型在机械响应方面的一致性。我们的结果表明，这种方法有能力在参与者测试之前识别潜在问题，确保研究工作流程更顺畅，并在参与者使用期间尽量减少干扰。
