Physically, the MK-series maintenance droid is quite unremarkable. The droid’s main body is blocky and mounted on a wedge-like turntable which is itself fitted to a set of bulky treads. A pair of cylindrical arms are mounted to rotating joints and end in fine manipulator digits that can easily undertake delicate repair work. The droid’s loaf-shaped head is mounted on a thin, telescoping neck that can add sixty centimetres to the droid’s height when fully extended. This enables the droid to explore areas where its bulky body cannot fit and make a diagnosis of the issues found there – a useful feature in cramped hull spaces and narrow service passages.

The MK-series is both an example of what can be achieved when a product designed engages the target market early on to obtain their input on what they want the product to do and what happens when this knowledge is not properly channeled and guided. When Kalibac Industries decided to enter the maintenance droid market, they had their designers and engineers consult a wide range of shipboard mechanics, restoration workers, and freelance technicians to garner information on the types of issues faced and solutions created. The resulting data went into the creation of the MK-series’ core processor, leading to a droid with remarkably flexible mechanical aptitude and problem-solving ability. On the flip side, the droid is quite independent-minded and prone to implement its own solutions when it comes to starship and facility repair and maintenance, sometimes in preference to the instructions given by its owner. This can lead to serious issues and at least partly explains why the droid is much less popular than its capabilities would suggest.
