Title:
MOBILE UNIT AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2008/035433
Kind Code:
A1
Abstract:
A mobile unit uses a wireless channel to read position information of IC tags, which
are distributed in a traveling area, for an automatic traveling. The mobile unit
has thereon a mobile mechanism for driving the mobile unit to travel; an IC tag
communication part (tag reader/writer) that communicates with IC tags to acquire
positional information; an antenna that is connected to the IC tag communication part
for establishing a wireless channel to the IC tags; an antenna moving part that
moves the antenna in the mobile unit; and a control part that controls the antenna
moving part to move the antenna in the opposite direction to the traveling direction
during the communication with the IC tags via the IC tag communication part. The
control part causes the antenna to be moved, for example, at the same speed as the
traveling speed of the mobile unit in the opposite direction to the traveling
direction during the communication with the IC tags via the IC tag communication part.
