Where did my robot go? Being robust and cautious during Laser-based Localization

Let’s imagine a scenario where a robot, either walking on two or four legs or moving on wheels, is required to explore a cluttered environment containing corridors, constrictions, uneven terrains or staircases. The robot would process proprioceptive inertial and leg/wheel odometry measurements, as well as exteroceptive observations from a 3D laser scanner. The odometry estimate [...]

Road vehicle localization with 2D push-broom lidar and 3D priors

In this paper we describe and demonstrate a method for precisely localizing a road vehicle using a single push-broom 2D laser scanner while leveraging a prior 3D survey. In contrast to conventional scan matching, our laser is oriented downwards, thus causing continual ground strike. Our method exploits this to produce a small 3D swathe of laser data which can be matched [...]

Laser-only road-vehicle localization with dual 2D push-broom LIDARS and 3D priors

In this paper we consider long-term navigation using fixed 2D LIDARs. We consider how localization algorithms based on scan-matching - commonly used in indoor environments - are prone to failure when exposed to a challenging real-world outdoor environment. The driving motivation behind this work is to produce a simple, robust system that can be utilized repeatedly over a long period, rather than [...]
