About

Benjamin Christie is a robotics researcher specializing in autonomous navigation, mapping, and perception for unmanned ground vehicles (UGVs) in challenging, unknown environments. His work focuses on enabling robots to operate effectively in low-visibility and subterranean settings, addressing critical defense and exploration needs. His most impactful paper, "Optimized low Size, Weight, Power and Cost (SWaP-C) payload for mapping interiors and subterranean on an Unmanned Ground Vehicle" (2020, 8 citations), tackles the challenge of identifying threats in dense urban areas by developing efficient sensor payloads. Christie also advanced autonomous exploration through "Autonomous navigation and mapping in a simulated environment" (2021, 4 citations), which combines frontier exploration with SLAM for efficient unknown environment mapping. His work on "ROS integrated object detection for SLAM in unknown, low-visibility environments" (2021, 2 citations) demonstrates innovation by integrating thermal imagery to enable UGV operation in darkness or smoke. These contributions collectively advance the practical deployment of UGVs in military reconnaissance, search-and-rescue, and industrial inspection scenarios where traditional sensors fail.
