ArXi:2509.17287v2 Announce Type: replace-cross Visual teach-and-repeat (VT&R) navigation enables robots to autonomously traverse previously nstrated paths using visual feedback. We present a novel event-camera-based VT\&R system. Our system formulates event-stream matching as frequency-domain cross-correlation, transforming spatial convolutions into efficient Fourier-space multiplications.
