Troubleshooting and improving an existing robot used in verification test

Sammanfattning

Reliable verification of radar measurements is essential for ensuring safe operationin industrial environments. At Emerson Rosemount Tank Radar AB, a wirelessmeasuring robot is used inside pipes to perform factory acceptance tests of a radartransmitter. However, recurring stoppages and poor communication with the robothave delayed the verification process. This project investigates the root causes ofthese issues and the connection to the communication system. To investigate andevaluate potential improvements, a test script was developed to log registers andcommunication response times of the robot.The results showed that relocating the Bluetooth transmitter improved communicationstability, and several hypotheses regarding the unknown stoppages could beruled out. In addition, the existing battery solution for the wireless robot is temporary,therefore three alternative concepts were developed and evaluated againsttechnical and usability requirements. To ensure the robot’s long-term operation, aspare parts analysis was conducted, revealing risks related to discontinued electroniccomponents and wear parts.The outcome of the project is a more stable Bluetooth connection and improvedlong-term maintainability of the measuring robot, helping to ensure its continueduse in factory acceptance testing.
