Overview
SilverHand integrates multiple engineering disciplines into a cohesive assistive device. The mechanical structure provides the physical interface and force transmission. The electronics capture and process biological signals. The power system enables portable operation. The control model translates user intent into actuator commands. And the software orchestrates all subsystems in real time.
Each subsection below provides detailed technical information sufficient to replicate, modify, or extend the design. All CAD files, schematics, and source code are available in the Downloads section.
