Big Finish’s full-cast audio drama series, The Robots, centres around what happens when Liv Chenka (companion of the Eighth Doctor, played by Nicola Walker) returns home for a year to join her sister Tula (Claire Rushbrook) on the planet Kaldor. There, technology is advancing at an alarming rate – and the robot workforce is adapting… 

This volume sadly marks the final Doctor Who credit of David Collings, here completing the story of Ander Poul. As previously announced, Gregory de Polnay returns to voice D84, last seen in 1977's The Robots of Death, the original Doctor Who television story where Kaldor first featured. 

The Robots: Volume 4 is now available at £19.99 as a collector’s edition CD box set or £16.99 as a download HERE!

During the events of Doctor Who: Ravenous 2, Liv Chenka left the Doctor and the TARDIS behind. Just for one year. A year during which she would live on Kaldor, and get to know her sister Tula all over again.  

But Kaldor is going through a period of tumultuous change. Technology is changing at an advanced rate - the robots are evolving, artificial intelligence is adapting, and with these changes so politics is altering too. Dangerously.  

Can Liv and Tula make a difference during the most turbulent time in the world’s history? 

The cast is completed by Pamela Salem (Into the Labyrinth, Counter-Measures), Jon Culshaw (Masterful, Dead Ringers) Sarah Lambie (Doctor Who: Ravenous), Glen McCready (Master!, Years and Years), Carolyn Seymour (Survivors, Star Trek: Voyager), Robert Whitelock (Informer, Marcella) and Tracy Wiles (The Beast Must Die, The Diary of River Song). 

Writer of box set opener Closed Loop Guy Adams said: “David Collings is a proper hero of mine, one of my favourite voices – it was a huge thing for me to be able to write for him, and it’s a proper loss that he’s gone. I pitched the story idea and John suggested that Gregory de Polnay could be involved, and it went from having Poul haunted by A robot to THE robot. It’s a very specific ghost from his past – it’s kill or cure, coming face to plastic once more. Or not... you’ll find out by the end of it all!” 

Writer of Off Grid Sarah Grochala said: “As a female writer, it’s really exciting to be part of a series that is so female-led, particularly one that is thinking about technology as people tend to think of it as a male dominated field." 

“I love Liv’s passion and determination to get to the bottom of everything. And Tula’s fascinating because she’s deeply committed to her work but is having to come to terms with some of the Company’s more dubious practices. She’s a scientist, but she’s also an artist in terms of her approach and commitment to the robots she creates.” 

Writer of final story The Janus Deception Robert Whitelock added: “Writing for Liv and Tula is pure joy. I know Nicola and Claire well from acting with them, and now when writing for them I can hear their character’s voices really clearly in my head as I create the dialogue.” 

The Robots: Volume 4 is now available at £19.99 as a collector’s edition CD box set or £16.99 as a download HERE!

The Robots: Volumes 5-6 are available to preorder as a bundle for just £38 on CD or £33 on download HERE.
