A transportable kitchen workcell includes a prefabricated enclosure, a robotic arm secured within the enclosure, one or more food appliances, a food prep area and storage, a sensor assembly, and a processor operable to command the robotic arm to autonomously prepare a completed entree from a wide variety of raw ingredients. A dispensing unit is arranged in the enclosure for dispensing the raw ingredients onto a target surface according to a selected flowrate and based on real time feedback measured during dispensing. The workcell is self-contained and is adapted to be conveniently moved (e.g., towed) to a new location. A wide range of entrees may be completed without rearranging or retooling the equipment in the workcell. New food items may be prepared by the workcell by simply selecting the applicable program, or by downloading an update corresponding to the new food item.
