A quadruped robot in the southwestern municipality of Chongqing has been recorded in the Guinness Book of World Records.
The robot was developed by a team with the College of Automation at Chongqing University of Post and Telecommunications. In a test last month, the robot traveled 134 kilometers in 54 hours, taking 340,000 continuous steps.
The previous record was set by a quadruped robot developed by Cornell University in the United States, which walked 65 kilometers in 30 hours.
Professor Li Qing-du and his team began developing the robot in November last year. The first prototype was produced in January.
Li says he will apply the technology involved to a wide range of robotic devices, to make them more efficient, durable and reliable. In the future, people could use the robots to undertake dangerous or remote tasks.

A spoonful of sugar can generate 80 hours of electricity for a battery, thanks to a novel microbial fuel cell developed by students from north China's port city of Tianjin.
A group of 19 college and high school students led by instructors from Tianjin University worked out a three-species co-cultured system of electricity generation. The team and their invention have won a gold medal and the title of best energy project, at the International Genetically Engineered Machine Competition earlier this year.
The poor performance of traditional single-strain fuel cells has inspired the team to extend their engineering capabilities to multicellular microbial consortia.
After technical optimization, the microbial fuel cell is able to generate the same amount of electricity output as a lithium battery, but with longer battery life, lower cost and zero pollution.
