1. Various of Kuka mobile robot rigged on a mobile table base approaching an enclosed cabinet in a University of Liverpool department for chemistry laboratory; the cabinet opens automatically, then the robot handles items, taking them on and off the table
2. Various of Ram Vijayakrishnan, a postdoctoral researcher at University of Liverpool, working on computer in lab
3. SOUNDBITE (English) Ram Vijayakrishnan, Postdoctoral researcher at University of Liverpool:
"So the robot behind me over here is called the KUKA Mobile Robot. It’s primarily used to transport samples around. Inside this workshop, we also have different robots that are there to synthesise, to perform reactions, to synthesise them. And we also have analysis robots, such as liquid chromatography, mass spectrometry, and NMR spectroscopy as well."

5. SOUNDBITE (English) Ram Vijayakrishnan, Postdoctoral researcher at University of Liverpool:
"These robots are really designed to be modular automation. They’re designed to work alongside human chemists in a standard organic laboratory. And they’re designed to conduct experiments that we wouldn’t normally do ourselves, for example."

7. SOUNDBITE (English) Ram Vijayakrishnan, Postdoctoral researcher at University of Liverpool:
"Here in our lab, they transport samples back and forth, they analyse the data, and they decide what to do next based on the results that they’ve been given, similar to how a human chemist would work."

15. SOUNDBITE (English) Yeow Qi Jie, PhD student at University of Liverpool:
"So effectively, it’s a mobile base, which I’m sure you’ve seen somewhere in the Amazon warehouses, with a mobile robotic arm. So effectively the mobile arm is able to pick up and then place items that’s on the base itself. And the base is able drive around and then able to load chemicals into various stations. And it’s also able to even partake in parts of the stations to help move valves within the station."

19. SOUNDBITE (English) Yeow Qi Jie, PhD student at University of Liverpool:
"It’s great, it’s a really huge time saver. So my reactions can take up to three and a half hours, two and a half hours. But if I’m doing it from back to back with the amount of reactions I need to do, every two and half hours I need to come back and then I need to do more reactions, whereas in this case I can set up multiple reactions to run and then, I can do other stuff. I’m free up, the time is freed up. But it’s also… When I’m at home at night, I don’t need to be back every two and a half hours to make sure that it continues running because it’s able to run throughout the night."
