JR East shows chainsaw-wielding robot for clearing rail tracks

Japan's JR East is using a humanoid robot with chainsaw and grabber arms mounted on a rail truck to clear branches obstructing tracks. The robot is currently teleoperated, but the company plans to make it autonomous with AI image analysis for detecting rail obstructions.

• The robot is mounted on a rail truck and remotely controlled by a human operator
• JR East is integrating AI and robotics for safety and round-the-clock track maintenance
• Future versions could be autonomous with AI-based recognition of obstructions
• The robot has been available to JR East engineers since March amid labor shortages
