A mural protection robot made its debut to great fanfare at a recent domestic exhibition on cultural relic protection.
The robot, developed by China Academy of Space Technology, a sub-unit of state-run China Aerospace Science and Technology Corporation, is designed to zap the bacteria clinging to murals with high-energy electron beam (EB).
This is the first time that robotics are applied in China to improve archeological work and cultural heritage preservation.
With a robotic arm attached to a mobile wheeled chassis, the device can train an EB projectile from different angles on designated sections of a mural within a vault.
The EB rays are able to kill off harmful bacteria that causes murals to fade or chip over time.

One of the benefits of the robot is its agility, allowing it to navigate tight space and narrow passages inside crypts.
This attribute proves useful for archeological work as many tomb murals are perennially exposed to high levels of humidity and decay easily.
Cultural relic preservation
Meanwhile, staff responsible for cultural relic protection have to work with extra care and caution as a misstep could result in further physical damage to murals.
Engineers at China Academy of Space Technology, who were tasked with exploring ways to protect tomb murals, turned to robotics for help.
The biggest obstacle that stood in their way, according to media reports, was the conditions of the environment in which the robot operates.
They came up with an autonomous robot capable of moving adroitly inside cramped vaults, rounding corners and extending its arm to hard-to-reach corners — all the while avoiding damaging murals.
Cultural heritage protection in underground tombs has been a long-standing issue. The birth of this robot has provided archeologists with new approaches to preserving cultural relics.
