Operation Sclerosis
Designed a 3-DOF assistive robotic arm enabling users with Multiple Sclerosis to play an unmodified Operation game without fine motor control. Developed a fully 3D-printed arm driven by MG996R servo motors; performed torque analysis confirming a 42% safety margin. Implemented Arduino-based control with joystick input for prototyping; integrated an electromagnetic end-effector and clip-on mounting system. Evaluated positional accuracy over 10–30 cm reaches, achieving 0.31–0.79 cm error, meeting design targets.

Process
- •Identified MS-related dexterity limitations through stakeholder research, defining accuracy, low-force operation, and minimal setup requirements.
- •Created sketches and CAD, then built a fully 3D-printed 3-DOF arm with MG996R servos and Arduino control, redesigning arm geometry to reduce torque after instability at longer reaches.
- •Tested positional accuracy and motor loading, tuned servo control and arm lengths to reduce distance-related error and validated performance with a 42% torque safety margin.
