National Grid, a leading energy company, has officially welcomed Boston Dynamics' robot dog Spot as a valuable addition to its workforce. Spot has been deployed to carry out routine maintenance and inspection tasks at the National Grid's HVDC converter station in Central Massachusetts. This innovative robotic companion is capable of replacing human workers in situations deemed unsafe.
Traditionally, conducting inspections at the converter station proved challenging due to the presence of electrical equipment. Workers were only able to perform sporadic inspections during scheduled downtime, often missing potential issues before they escalated. Recognizing the need for a more efficient solution, National Grid introduced Spot to improve operational efficiency and safety.
Dean Berlin, a lead engineer at National Grid, emphasized the significance of the converter station, stating,
"It's a very critical site for New England. If we experience a forced shutdown, securing alternative resources becomes extremely expensive. Maintaining the facility's operations effectively requires a combination of meticulous maintenance and operational tools."
Although Spot was initially deployed as a pilot project two years ago, the robot dog has now become an integral part of the company's operations. Spot autonomously navigates through the site, utilizing an infrared camera mounted on its frame to identify potential leaks or anomalies.
Berlin noted, "Nearly all of our current projects rely on data collected by Spot. The robot has significantly enhanced safety measures, and Spot is now considered a valuable team member."
To ensure continuous connectivity, National Grid strategically placed 14 radios around the site, eliminating any dead zones and establishing a seamless communication channel between operators and Spot. This network enables operators to monitor Spot's progress in real-time from a control room.
Berlin explained the benefits, stating,
"This capability is significant. We can control Spot directly from our control room. There's no need to send a human operator each time we want to use the robot, even for manual missions. The operator can sit in the control room, monitoring the 20 other screens required to oversee all aspects of the converter station. Spot essentially becomes the 21st screen."
Looking ahead, National Grid has plans to further enhance Spot's capabilities. The company aims to equip Spot with an acoustic imager and 3D scanning tools, expanding its range of functionalities and applications.
By integrating Spot into their workforce, National Grid is at the forefront of leveraging robotics and automation to optimize maintenance operations, improve safety, and enhance overall efficiency in the energy sector.
