Tongue Tied

Mechanoids are a type of android (human-like robot) designed and manufactured by DivaDroid International to perform simple household tasks for human owners. Many models, such as the Series 4000 come with numerous attachments, such as a groinal attachment and are programmed for daily tasks, such as cooking, cleaning and ironing. Individual mechanoids include Kryten ("Kryten"), Able ("Beyond a Joke") and Hudzen-10 ("The Last Day").

Although Kryten had his software installed at "Toilet University", most mechanoid programming is very advanced, including the ability to feel complex emotions, such as loyalty and humour. However this programming also limits the mechanoid's feeling, as it is unable to lie, be egotistical or refuse a direct order from an owner. Some mechanoids, such as Kryten, are able to break these programming limitations with the help of patience and persistence while others, such as Hudzen, have done so due to their sanity chip being worn down due to being alone for thousands of years.

Mechanoids could swap heads, and maintenance could be done upon them by propping them up like a car bonnet. The circular, reflective part at the mechanoid's chest was a monitor used for display. ("Tikka to Ride") Mechanoids could inject a robotic narcotic, Outrozone, directly behind the chest monitor, but this caused the mechanoid's circuits to degrade. Drug-addict mechanoids were called "Zoneys", and once such mechanoid was Able, Kryten's brother. ("Beyond a Joke")

Mechanoids are programmed to believe in Silicon Heaven to make them better servants to humans. ("The Last Day", "Beyond a Joke") They have an advanced self-repair system that can repair damage at the molecular level, thanks to nanobots. ("Nanarchy")

The reception mechanoid at the Ganymede Holiday Inn

The Ganymede Holiday Inn used mechanoids as hotel staff bell boys and receptionists.

Groovy Channel 27 had a soap opera specifically designed for mechanoids called Androids.

Simulants, such as the Convict, lacked the same degree of restrictive programming as mechanoids.

Simulants, such as the Convict, were similar to mechanoids, but lacked the same degree of restrictive programming due to their having been created for war — though in the event, the conflict that necessitated their creation in the first place never happened.
