📄 RESEARCH

ROBOT SPATIAL MEMORY

  • MIT's spatial memory system for robots efficiently indexes objects observed during exploration, enabling a robot to later answer questions about where objects were left. This addresses a persistent gap between exploration data and object-level retrieval in mobile robots.

CONSTRUCTION ROBOTICS WITH SIM-TO-REAL TRANSFER

  • Visual sim-to-real learning enables robotic rebar insertion at 1.4 mm clearance by training policies that handle two levels of geometric variation: nominal design per structural member and fabrication tolerances around each nominal. The work is directly relevant to automating one of construction's most physically demanding repetitive tasks.

RADIO-SOURCE LOCALIZATION FOR ROBOTS

  • MAGNETAR infers a joint posterior over planar position and heading of a radio transmitter using upper-mid-band multipath signals, giving robots uncertainty estimates rather than single point guesses in cluttered indoor spaces. This is more useful than point estimates for navigation planning under occlusion.

FEDERATED LEARNING ROBUSTNESS

  • Distributionally robust federated learning with multi-source data addresses the common real-world condition where the true mixture of data-generating distributions across clients is unknown, hardening models against worst-case distributional shift without sharing raw client data.

PREDICTIVE MAINTENANCE ACROSS MACHINES

  • FreqCondNorm introduces frequency-conditioned normalization in a Transformer foundation model for predictive maintenance, enabling cross-domain transfer across machines and sensors whose signals span five orders of magnitude in sampling frequency from 1 Hz to approximately 100 kHz. This directly targets the poor transferability that has limited industrial deployment of deep learning maintenance models.
