4 Robot location-aware technology research

Features and advantages & disadvantages

• Being different from the existing location-aware sensor, it provides distance information with a ultrasonic transmitter-receiver.
• By fusing the above information with the vision recognition information, it acquires the distance and azimuth information of robot.
  
• It enables you to overcome the instability of location information by furnishing distance information to the impact of ambiguous situation such as a boundary point, and the difficult situation to distinguish due to similar shape at the different locations.
• Available to be used as a means to regularly verify results made with vision.
• Supplementary means.
• Available to acquire location information that can not be obtained from vision only.

Performance indicator

• Location precision (Distance)
  between the actual coordinates and coordinates recognized by robot.
• Location precision(Azimuth)
  between the actual azimuth and azimuth recognized by robot.
• Update time of location information cycle to renew the old data by acquiring the new data with localization sensor.
