• Robotics Engineer in Automation and Autonomy department• Project: Autonomous multi-vehicle formation driving and grain transfer over uneven terrain• Developing in old, massive C++ code base• Delivered (so far): o Ground-up redesign and implementation of mission-critical camera-to-GPS calibration process - Used stereo vision techniques to estimate camera orientation relative to GPS unit - “No pressure, Ben, but this MUST work. Welcome to the team!” (I delivered) o Coordinate system adjustment feature to compensate for uneven terrain (farm fields are not flat) - “This was one of the most important unsolved problems on this project” o Updates to and support for numerous existing features• Sought out combine and tractor solo operation certification to facilitate faster development and debugging of my features o Only developer on my team to do that aside from our tech lead• Rode along during real corn and wheat harvests, spoke to real users o Hugely helpful to understand the larger picture of my project o Helped me deliver better code
