* Designed an integrated torque limiter in a parallel jaw mechanism to be tested on Ranger in neutral buoyancy * Created a silicone mold for a low-profile hollow bore Oldham coupling used to mitigate axial misalignment * Migrated CAD drawings from IDEAS to Siemens NX 10 by documenting sketches and assembling part files * Outlined procedures for sealing assembly, adjusting, and operating the PJM with precautionary failure modes

* Configured data packets in LabVIEW using UDP and TCP protocol for SpaceX telemetry stream through a cRIO * Designed a motor shield to test Maxon EC motors through RS232 and CAN bus gateway communication * Integrated a transfer function with LabVIEW to read thermocouples with autozero and dynamic CJC temperatures * Designed and documented testing and configuration procedures for 50A current sensor and motor controllers * Programmed transfer functions for various analog sensors in Xilinx FPGA using LabVIEW

Analyze encoder-resolver miscompare during motor motion and quiescence over robotic arm joints, sample caching arm joints, and bit exchange rotary mechanism using Pandas in Jupyter Notebooks. - Write, execute, and document procedures for fault protection testing of enabling and disabling motor control components on Mars 2020. - Troubleshoot immediate issues with execution of motor systems in Assembly, Test, and Launch Operations (ATLO)

* Led software and electrical teams of 30+ students to build a competitive robot in 6 weeks, $50k Budget * Managed the development of robot software with sensor placement, electrical design, and testing * Organized versions of software development by creating as SSH repository * Evaluated risk to development paths by implementing a Gantt chart to organize deadlines and a critical path * Created an Android application to assist in collecting data about other robots’ performance during competition
