Robot Sensor Fusion and Uncertainty: When the World Disagrees

Mon, 18 May 2026 00:00:00 +0000

A robot rarely sees one clean version of the world.

The camera notices a bright edge on a box. The depth sensor reports a surface that is partly missing because the material is glossy. The lidar sees a clean obstacle outline but not the thing sitting on top of it. Wheel encoders say the robot moved a little farther than the floor markers suggest. The IMU reports a bump that looks like a quick tilt. A force sensor says the gripper touched something before the vision system expected contact. None of those signals is the whole truth. Each is a partial measurement made from a particular place, at a particular time, with its own failure habits.
