For our experiments, we use the omni-directional wheeled autonomous robot shown in Figure 2 that is equipped with a 802.11n WiFi dongle with a RT3575 chipset. During normal operation, the robot moves at speeds of up to .75 m/s. Prior to these experiments, the robot was driven around the environment while the dongle was set to monitor mode in order to capture RSSI of wireless signals transmitted by surrounding APs. The wireless measurements were bucketed by location into 1m x 1m grids. The wireless map used in our work reflects the median RSSI of each AP observed in each grid.
