Laboratory robots with built-in artificial-intelligence software can look after stem-cell cultures independently.

The Robotics Innovation Center at the Institute of Science Tokyo opened its automated laboratory in April. Later this year, the lab will be made available for use by other researchers at the institute, says Genki Kanda, an automation researcher who works at the robotics centre. He says that the lab’s ultimate goal is to create a “factory-scale” facility with thousands of robots that could be used by local and international scientists by 2040 or 2050. A laboratory with that many robots would be exciting, says Yan Zeng, a materials scientist at Vanderbilt University in Nashville, Tennessee.…
