چکیده
In this paper, the mobile robot position fusion algorithm is inaccurate. There a delay, and map-construction accuracy not high; an improvement method proposed. First, Cartographer optimized. Radius filtering used for data processing after voxel filtering. contrast, idea of multi-sensor to fuse processed IMU information. This improved improves efficiency positional pose fusion. We verify effect applied environment map, respectively, in experimental building promenade teaching hall environment, analyze compare map construction before improvement; experiment proves that absolute error measuring analyzing obstacles reduces by 0.06 m, relative decreases 1.63%; longest side 1.121 m decreased 5.52%. addition, during operation, CPU occupancy optimized around 59.5%. original 67% on average, sometimes it will soar 75%. The results prove paper significantly performance all aspects when constructing real-time maps.

Sonar based map building for a mobile robot
This paper describes a mobile robot equipped with a sonar sensor array, Werrimbi, in a guided feature based map building task in an indoor environment. Common indoor landmarks such as planes, corners and edges are located and classified with a multiple transducer sensor array. Accurate odometry information is derived from a pair of narrow unloaded encoder wheels. Discrete sonar observations are...
