Sonar-Based Mapping With Mobile Robots Using EM
Unproblematic if the robot approximately knows its posi-tion (in which case the mapping step is identical to occu-pancy grids [Elf87, Elf89, Mor88, Thr98]), this indepen-dence assumption leads to highly ambiguous maps when the robot is uncertain, which makes it difficult to local-ize the robot with sonar sensors. Here we replace these ... Return Document

Multi-Robot Teamwork In Multistatic Sonar
Transmitter. Multistatic sonar is a coordinated effort aimed at gaining a more accurate view of the target and discriminating it from the background. However, multistatic active sonar is more than sonar technology. It is a system of hardware platforms and sophisticated software modeling and signal processing algorithms that are networked together. ... View This Document
