This paper proposes a light-weight navigation platform that consists of gyro-assisted odometry, a 3D laser scanner and map-based localization for human-scale robots. The gyro-assisted odometry provides highly accurate positioning only by dead-reckoning. The 3D laser scanner has a wide field of view and uniform measuring-point distribution. The map-based localization is robust and computationally inexpensive by utilizing a particle filter on a 2D grid map generated by projecting 3D points on to the ground. The system uses small and low-cost sensors, and can be applied to a variety of mobile robots in human-scale environments. Outdoor navigation experiments were conducted at the Tsukuba Challenge held in 2009 and 2010, which is an open proving ground for human-scale robots. Our robot successfully navigated the assigned 1-km courses in a fully autonomous mode multiple times.

The Tsukuba Challenge is a proving ground for mobile robots, the task of which is autonomous navigatoin along a predefined path of 1km in outdoor environments. We joined the Tsukuba Challenge and achieved the tasks in 2009 and 2010. This paper focuses on the problem analysis and basic design of our navigation system, and presents the design policy and lessons learned in the experiments. Our system consists of gyro-assisted odometry, a roundly-swinging 3D laser scanner, a fish-eye camera, and a localization method using map matching and a particle filter. The integration of these technologies made our system highly reliable to achieve the task.
