The COO cook droid was a class-five chef droid created as a joint venture between Industrial Automaton and Publictechnic before the First War. The droid model came equipped with over a dozen arms, which were equipped with common cooking tools such as spatulas, knives, and spoons. Designed for catering on a large scale, such as in military mess halls, the droids came with only a few hundred of the most common recipes, and although this software could be replaced with another package containing different recipes, the process to do so was very complex. Because of this, few owners did swap their droids' software packages. This lengthy process was a flaw commonly noted by customers. Ultimately, many owners ended up using the droid for nothing more than heating up meals or serving prepackaged foods.
