Study on inspection robot for substation based on ultra-wide-band wireless localization system

UWB (ultra-wide-band)-based wireless localization technology for a substation inspection robot is studied and the inspection robot system is designed. The localization algorithm with weighted K nearest neighbors is proposed. The localization experiments of inspection robot are carried out in this paper. The results show that the performance of the proposed algorithm is optimal by comparison with triangular localization algorithm and linear least squares algorithm. And the inspection robot can work with good navigation accuracy.
