Karel

Karel is a mass-produced GN powered frog-like maintenance robots appeared in Mobile Suit Gundam 00. The unit is piloted by Haro's.

Introduction
To compensate for the lack of a full crew, Plotemaios and Plotemaios II has a large number of Haros and Karels to substitute a human crew. The Karels themselves are low-level thinking maintenance bots, should more complicated tasks are given (ex: Gundam repairs, system repairs), the Haros will dock with the Karels to complete the task. The maintenance-bots themselves are only able of completing a certain level of repairs and ultimately require a human engineer to complete the job. It's why the engineer is often supervising the Haros and Karels during their work; due to their tireless nature, they often complete major repairs in a speedy manner that contributes to the survival of the ship and the Gundams. In order to do the repair work,GN Welder(s)are built in the Karel's arms.
