A Step Towards Automated Tool Tracking on Construction Sites: Boston Dynamics SPOT and RFID

Abstract

Tool tracking and inventory management on a construction project is often more reactive than proactive. It is not that tools are not of value, but to larger firms, a certain comfort level exists with a loss to a relatively small line item, especially when compared to the resources that may be expended to track the tool inventory. With current market construction robotics serving a number of uses, testing multiple applications of autonomous robots creates more return for end-users. This research aims to execute a proof of concept for automated tool tracking using an autonomous robot and RFID technology. The research was carried out with three types of scans namely: Human held RFID reader; Robot mounted RFID reader in manual mode; Robot mounted RFID reader in autonomous mode. A total of 39 tools were tagged using passive UHF RFID tags and the study looked at the average cycle count time it took time to read 39 tags for the three scan types and the reliability of the robot and RFID technology. Results show reliability of the autonomous robot in acquiring RFID information, including zero failures in tag identification and autonomous guidance.
