As part of the instrumented objects team on the GT PoWeR Lab's ARMS Research Vertically Integrated Project, I design and fabricate custom hardware fixtures that let ATI force/torque transducers and force plates capture the biomechanical data behind an assistive exoskeleton's control system.

Working alongside teammates Anthony and Sam, my primary responsibility is parametrically designing custom hardware interfaces in SolidWorks — including the fixtures detailed in my Precision Disk Design Document — that are then rapid-prototyped via 3D printing to mount directly to ATI multi-axis force/torque transducers and force plates.

To keep the sensor telemetry accurate, I run static mechanical analysis by hand: free-body diagrams to trace load paths, resolve applied force vectors, and map how moments interact with the 3D-printed fixture geometry under load, so the fixtures don't introduce error into the readings they're meant to capture.

The instrumented setups are built to quantify the multi-dimensional kinetic forces behind specific hand motions from "The GRASP Taxonomy of Human Grasp Types" (Feix et al., 2016). That hardware-to-software pipeline hands off high-fidelity biomechanical data to a cross-functional team, which trains the machine learning models behind the predictive control system of an assistive exoskeleton suit.
