The introduction of digital tools in the transportation industry has led to significant advancements in vehicle maintenance and repair. The Deutsche Bahn (DB) has been at the forefront of this digital transformation, utilizing various tools such as automated wheelset measurement systems, AI-powered camera bridges, and underground robots. Adding to this impressive lineup is the “Spot” walking robot, developed by Boston Dynamics. With its cutting-edge technology and ability to access hard-to-reach areas, “Spot” is set to revolutionize the maintenance of vehicles, particularly in the railway sector.
DB introduces innovative robot ‘Spot’ for efficient maintenance
The “Spot” walking robot, developed by Boston Dynamics, is a cutting-edge technology that resembles a dog with its four legs. Its advanced capabilities allow it to be deployed in areas that are difficult or dangerous for humans to access, such as underneath trains. The remote maintenance software is provided by the German startup Energy Robotics, which customizes the system to meet the specific requirements of the DB and offers it as a “Robot as a Service” rental. Weighing 25 kilograms and standing at 84 centimeters tall, the robot can reach speeds of up to 6 kilometers per hour. It is highly durable and exhibits impressive agility. Following its debut at the InnoTrans 2022, “Spot” is now being implemented for the first time in a DB-specific environment.
Spot” the robot reduces inspection time and increases safety
In a six-week test, the robot “Spot” will be used in two different scenarios at DB Cargo. Initially, it will be tested for wagon location using RFID and character recognition on two tracks. Following this, a visual inspection of wheelsets from the maintenance pit of the freight car workshop will be conducted. This robot can reduce travel distances by 50%, provide objective inspection results, and enhance safety by eliminating the need for pit work.
The implementation of the Spot robot in DB Cargo’s maintenance processes not only relieves employees of physically demanding tasks but also allows them to focus on more value-added activities. This leads to a reduction in maintenance costs and helps alleviate the shortage of skilled workers. If Spot proves successful, it could potentially take over these tasks in four DB Cargo facilities, and its application could be expanded to include other scenarios, such as detecting loose brake hoses and leaks in freight wagons.
Robot “Spot” revolutionizes maintenance of freight trains, boosting efficiency
The implementation of the walking robot “Spot” brings numerous advantages to the maintenance of freight trains. With its ability to access hard-to-reach areas and perform visual inspections, damages to the train can be detected and repaired early on. Employees are relieved from time-consuming routine checks and can focus on important repair tasks. As a result, the train’s pit stops are shortened, creating short-term capacity for transporting goods. The digitization, especially the use of robots like “Spot,” is therefore a crucial factor for a successful shift to sustainable freight transportation by rail.
