"[6] According to the BBC, Byker Grove tackled "many controversial issues" including a gay storyline between characters Noddy and Gary which even led The Sun to call for Robinson to be sacked at the time.

Having previously worked for producer Julia Smith on Angels, Robinson was employed to be lead director of BBC1's soap opera EastEnders when it launched in 1985.

In 1998 Robinson was appointed executive producer of EastEnders by Mal Young (BBC Head of Drama Series) and Peter Salmon (Controller of BBC1), and nicknamed the "Pope of Soap" by The Sun.

In their place Robinson introduced new long-running characters including Melanie Healy (Tamzin Outhwaite), Jamie Mitchell (Jack Ryder), Lisa Shaw (Lucy Benjamin), Steve Owen (Martin Kemp), Billy Mitchell (Perry Fenwick) and reintroduced Janine Butcher as a villain played by Charlie Brooks.

In addition to KMF's numerous TV dramas, documentaries and TV spots, he has produced ten Khmer language feature films, seven released on the Cambodian cinema circuit – Staying Single When 2007, Palace of Dreams 2008 (for BBC World Service Trust), Vanished 2009 and Price of Love 2016 (directed & written by Robinson based on an original story by BBC Script Producer Stuart Cheetham).

King Selfie (directed and written by Robinson based on a story by English novelist Matthew Baylis), released in Cambodia in March 2018.

The 7th film Move Out (in the popular 'Khmer Ghost Movie' genre) was released across Cambodia on 5 December 2019 achieving excellent box office returns.

Shooting on a 9th film Day in the Country was completed in December 2019, a four-year project about an arranged marriage written and directed by Robinson.

A 10th feature film, Dance Till You Drop, a Bollywood-style movie set in Phnom Penh, started shooting in February 2020 but had to be abandoned in March because of dangers to the performers and crew from COVID.

Since 2015, Robinson has written a blog on EastEnders fansite Walford Web, sharing anecdotes about his two stints working on the show (1984–87 & 1998–99).
