Summary
🤩
Rockstar🎓
Top SchoolJoshua Wallace is a robotics software engineer with seven years of experience building robust autonomy at Locus Robotics and prior controls work at DEKA. He specializes in ROS 2 navigation and behavior tree design, contributing core path validation, replanning, and error-handling improvements to the widely used navigation2 project and its documentation. His background blends embedded control work—implementing PID and sliding mode controllers on Teensy microcontrollers for quadcopters—with higher-level autonomy, showing fluency across firmware, C++, and system-level integration. Collected experience in simulation, experimental validation, and documentation means he not only implements algorithms but also ensures they are testable and well communicated to teams and users. Based in Manchester, NH, he brings a hands-on, systems-oriented approach that tightens reliability in real-world robotic fleets.
