Unsupervised learning with Slow Feature Analysis (SFA) enables an agent to learn spatial representations of its environment from images captured during an exploration phase. In a subsequent application phase, slow features encode the robot’s position. The representation is spatially smooth and implicitly encodes the average travel time during exploration. Following the SFA gradient allows the robot to navigate even around obstacles without any planning. Earlier work showed this basic principle in noise-free simulation, using two virtual cameras on a robot. We extend the approach to be more robust and more computationally efficient. We test it on a lawn mower robot with a single camera for navigation in free space and avoiding obstacles.
