About

Erik Nelson is a leading researcher in multi-robot systems, with a focus on cooperative localization, mapping, and autonomous exploration. His most impactful work tackles the fundamental challenge of enabling multiple robots to collaboratively build maps and determine their positions without prior knowledge of each other’s locations. In his highly cited 2015 paper (82 citations), Nelson introduced a novel, uncertainty-aware Expectation Maximization (EM) approach for distributed, real-time cooperative localization and mapping, allowing robots to efficiently identify inlier loop closures from indirect measurements. His 2014 follow-up (72 citations) extended this to multi-robot pose graph localization and data association from unknown initial relative poses, a critical capability for deploying robot teams in GPS-denied environments. Beyond multi-robot coordination, Nelson has advanced autonomous exploration through information-theoretic occupancy grid compression (2015, 21 citations), enabling high-speed exploration on computationally constrained platforms, and developed AtomMap (2017, 11 citations), a probabilistic amorphous 3D map representation that relaxes traditional tessellation constraints. His work on environment model adaptation (2017, 23 citations) further accelerates exploration by dynamically adjusting the robot’s internal world model. Nelson’s contributions have been widely recognized, with over 200 total citations, establishing him as a key innovator in robust, scalable multi-robot autonomy.
