    • A mobile robot includes a radio communication unit; a radio environment detector detecting plural types of radio environment data indicating the degree of goodness of radio environment, a comprehensive radio environment data being calculated from results of weighting the plural types of radio environment data with predetermined weights; a self-position detecting unit; a storage for map data of a movement area; the calculated comprehensive radio environment data being written in association with its own position detected. The robot moves at a movement speed not higher than the maximum movement speed determined so that communication with the radio base station is not cut off during movement and, if radio communication is cut off, searches the radio environment map for a communication restoration position where the radio communication is feasible to establish and moves to the communication restoration position and has the radio intensity reporting control section reporting the determined level of radio intensity.

    • A message guaranty system for having a reliable third party (evidence preparing server) prepare evidence information attesting to the transmission and reception of a message by a transmitting and a receiving terminal. When the transmitting terminal furnishes the target message with evidence information before transmitting them to the destination, the system attests to the transmission and reception of that message once they are completed. When a message is to be sent illustratively from a workstation (WS) 1 to a workstation (WS) 2, the third-party evidence preparing server on the network first prepares transmission evidence based on a request from the WS 1 and sends it to the WS 1. The WS 1 sends the message along with the evidence to the WS 2. The evidence preparing server then prepares reception evidence based on a request from an evidence verifying server (a third party) acting for the WS 2. The reception evidence thus prepared is retained by the evidence preparing server and is also returned to the evidence varying server. The evidence verifying server retains the reception evidence. When an application program on the WS 1 requests verification of the reception evidence, the evidence verifying means verifies the presence of the reception evidence and returns the result of the verification to the WS 1.
