Define and own subsystem communication architecture and protocols (for example Ethernet/GigE, EtherCAT, CAN, serial, USB, and camera/frame-grabber links), including timing, synchronization, bandwidth, and latency budgets between controllers, motion axes, cameras, illumination, and sensors. Develop and maintain error and noise budgets (EMI/EMC, signal integrity, power integrity, timing) and define subsystem-level requirements to be characterized and validated during system alpha testing for current and future products.
