It’s all systems go on the planet of Kaldor, as Big Finish reveals more details of The Robots series and announces its renewal for two further volumes of adventures for the Chenka sisters. 
 
In the next volume, due for release in June 2021, they are joined by an old friend as 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, D84 was an undercover agent who helped the Fourth Doctor (Tom Baker) solve a murder mystery.   
 
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) among these highly artifically intelligent androids.  
 
The Robots: Volume 4 is now available to pre-order at £19.99 as a collector’s edition CD box set or £16.99 as a download, exclusively HERE! and the three new story titles are as follows: 
 
Closed Loop by Guy Adams 
Off Grid by Sarah Grochala 
The Janus Deception by Robert Whitelock 
 
This will not be the end of the story, as The Robots will return for two further volumes, due for release over the next year.  
 
Producer David Richardson said: “The Robots, as you may know, was originally planned to be four box sets. But, as we went along, we just discovered that we had way too many ideas. We had too much story to tell, and could not do it justice in just 12 episodes. Thankfully, the series has been a huge success and has earned its recommission, and so I’m delighted that we now have six more episodes to explore Liv Chenka’s year on the planet Kaldor.” 
  
The Robots: Volume 4 is now available to pre-order at £19.99 as a collector’s edition CD box set or £16.99 as a download, exclusively HERE! 
 
The Robots: Volumes 5-6 are now available to preorder as a bundle for just £38 on CD or £33 on download.
