A study on control/surveillance of wireless robot and information transmission

摘要

By the indoor wireless robot in a hospital or a residence, in order to perform control of the robot for care welfare and surveillance of a client to need care, information transmission/processing technology was more indispensable. In this paper, at first to clarify indoor multipath propagation characteristics in Wireless LAN, we carried out measurements of delay profile using Network Analyzer at UHF band under some typical environments of our university. Based on measured average delay and delay spread, we derived correlation bandwidth. Secondly, we proposed new reinforcement learning algorithm using multiple derivation field from divided environments. In our simulation we show the effectiveness of this algorithm for control of the robot to reach a goal and avoid collisions.
