To isolate motion from the omni-directional robot base, a gimbal motor is utilized to link the base and the LiDAR, thus the LiDAR can be stabilized and rotated independently. Hence the accuracy and robustness of LiDAR odometry are improved. To actively choose an optimal gaze angle during traversing, first the feature points are extracted; second the feature statistics are computed using Ripley K function; then a robot-centric grid map containing those information is built;finally the angle optimization is conducted utilizing grid-map and Fisher information. Several simulations are performed to verify the usefulness of the proposed grid-map, and the improvement of odometry accuracy by this approach. We demonstrate that this approach can alleviate odometry drift caused by robot base rotation and perception of texture-less areas.",[11,12,13,14,15,16],"Yang, Mengshen","Jia, Fuhua","Rushworth,
