Forum user and roboticist madhatter101 has just introduced his newly ROS enabled hexapod, Rhoeby! Built on a Robotis Bioloid kit, it uses a TeraRanger 2D LiDAR (from Rhoeby Dynamics, hence the name) to scan its surroundings. It supports SLAM, Navigation, and Dynamic Obstacle Avoidance. Rhoeby is pretty slick, more details on the forums.
