WebSep 30, 2016 · In this work, we choose to use Rao-Blackwellized Particle Filter (RBPF) to perform robot’s state estimation. RBPF is a derivation from particle filter estimation theory. In RBPF, the dependencies of robot pose and map are exploited. Each particle contains a hypothesis of robot pose that assume its position is correct.
