Assistive Medical Robot Development Case Study

This case study outlines the collaboration between Simplexity Product Development and a medical device maker to transform a wearable assistive motion system from a proof-of-concept into a clinically ready product. The document details the challenges faced, including the need for improved robustness and precise torque control, which were addressed through the integration of the Juno MC73113 control IC from Performance Motion Devices (PMD). It describes the importance of torque control in ensuring smooth and predictable motion, emphasizing the role of field-oriented control (FOC) in achieving this goal. The study also highlights the parallel development of hardware and firmware, facilitated by PMD's development kit, which allowed for early firmware development and testing. Additionally, it discusses the debugging process, where issues with encoder signaling were resolved with PMD's support. The successful integration of the MC73113 led to a quieter and more reliable user experience, positioning the device closer to clinical application.
