A significant hardware risk to the current status of the project is not being able to locate hardware that meets our use case requirements. However, we hope to mitigate this by: taking note of tech specs prior to purchase and ensuring they fit our scope, having backup individual parts instead of only fully integrated tools to promote customization/flexibility.
Since defining our abstract, a few changes have been made.
Sole velocity metric: We initially were set to focus on velocity as our core metric for providing data feedback on a lift, but have since expanded this to acceleration, displacement, balance, and torque. This change will allow for a more in depth analysis of a user’s performance and provide more information for improvement. It should also make data collection for app functionality easier. We will have to add more parts into our design to make this possible, but many products on the market seem to offer small device solutions to these metrics.
Metric app comparison: Due to limited research, we had planned to perform testing/verification on our data by cross referencing it with an existing product. However, we cannot believe another product’s information to be 100% accurate, and thus developed an automated pulley system to establish “ground truth” for our sensors so we can ensure a set of robustly correct data is available to cross reference after we calibrate the sensors.
No schedule changes have occurred.
