July 26, 2023 (Beijing time)

National Key R&D Program "Intelligent Robots" Key Project

“FAST, a major scientific infrastructure

The project of "operation and maintenance robot system" passed the acceptance

The world's most sensitive single-aperture radio telescope

Operation and maintenance are the top priority to ensure its observation

The projects that passed the acceptance this time include

Five robotic systems and platforms

They are

Feed support cable and pulley inspection robot

Actuator Automation Maintenance Robot Platform System

Reflective surface laser target maintenance robot

Feed receiver disassembly and assembly robot and radio interference intelligent monitoring system

Feed cabin all-weather intelligent measurement system

in

Feed support cable and pulley inspection robot

It will be difficult for humans to reach the 100-meter high altitude

6 cables and pulleys undergo safety inspection

Actuator Automation Maintenance Robot Platform System

2225 hydraulic actuators for the active deformable reflective surface

Conduct efficient and proactive maintenance

Reflective surface laser target maintenance robot

It will realize the large slope and the difficult to reach by human

Laser target maintenance on reflective surfaces

Feed receiver disassembly and assembly robot

And radio interference intelligent monitoring system

Automatic replacement of feed receivers in different frequency bands will be realized

Identify and locate sources of radio interference

Feed cabin all-weather intelligent measurement system

Will overcome the impact of climate on existing measurement systems

Achieve all-weather observation

Comprehensive acceptance of the robot system for operation and maintenance work

Will improve the efficiency of telescope use

Annual observation time is expected to increase by 30 days

Promoting the output of astronomical results

China's Sky Eye

Located in Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province

It is a major scientific and technological infrastructure construction project of the country's "Eleventh Five-Year Plan"

Completed on September 25, 2016

Passed national acceptance in January 2020

Officially opened for operation

Supporting the world's largest and most sensitive

Single-aperture radio telescope

No experience to follow

Facing unprecedented challenges

Scientists of the "China Sky Eye" rely on

The tenacity of “holding on to the green mountains and not letting go”

The fighting spirit of “never return until Loulan is conquered”

The spirit of “flattening the bumps and making a road”

Constantly challenge the limits of cognition and technology

Continuously expanding the boundaries of human observation of the universe

On August 25, 2022, Jiang Peng (back), executive deputy director and chief engineer of the FAST Operation and Development Center, talked with staff in the control room of the "China Sky Eye" (photographed during maintenance). Xinhua News Agency reporter Ou Dongqu

Since October 2019

FAST's annual observation time is stable at around 5,300 hours

Telescope performance is also constantly improving

Sky survey efficiency increased by an order of magnitude

More than 800 new pulsars discovered

It is the first observation equipment of the same type abroad in the same period

More than three times the total number of pulsars discovered

Become the most efficient pulsar searcher in the world

Radio telescope

Scientific research papers based on FAST results in the past three years

About 150 articles

This "giant eye" has entered

The stage of producing good and great results

On the road to the universe

China's Sky Eye keeps moving forward

The Eye of Heaven

No end
