       第38回計測自動制御学会北海道支部学術講演会論文集,pp.103-104,2006-1
      We already developed operation instruction system to mobile robot using
      the infrared remote controller. This time, controller buttons to change
      human tracking or guidance and to select clothes color are increased. Besides,
      audio outputs from robot are added. Experiments show that direct operation
      of remote controller and audio output improves interface between robot
      and human.
