Robotic Chef ‘Beastro™’ takes Orders, Cooks—and Cleans up!

Industry- Food & Beverage

The Customer

Kitchen Robotics™ is the global leader in the development of versatile, programmable, and client-operated commercial robotic kitchens. The company's flagship product, Beastro™, is designed to bring efficiency, precision, and consistency to food preparation, making it an ideal solution for businesses seeking to optimize their kitchen operations.

The Challenge

To create robotic ‘chef’ machines that receive customer orders from the Cloud via a website or app, and can accurately weigh, mix, and cook orders according to precise recipes—and that also wash the pots after preparation.

Products Used

Unitronics’ UniStream® PLCs and AC Servo Drives and Motors, programmed in UniLogic All-in-One software


The Kitchen Robotics company Cloud receives the customer orders via website or app and sends the appropriate commands to the UniStream PLC, using an API that implements a dedicated TCP/IP protocol written in UniLogic, Unitronics all-in-one development software.
The UniStream PLC then interprets the data and precisely controls all the necessary equipment for food preparation, ensuring consistent and high-quality dishes.

Raw ingredients are precisely dispensed by dry food and liquid dispensers comprising stepper motors controlled by serial communication, ensuring

accurate Kitchen Robotics: Precise Recipe Execution with Unitronics PLCsmeasurement by weight via closed-loop control. The system contains approximately 37 dosing stations that handle liquids, powders, and solids.
During the cooking process, 6 Unitronics AC Servo axes transport the pots through the cooking stations, moving the pots on and off induction surfaces according to order.

When the dish is complete and the food served, the machine transports the pot to the cleaning station to be washed and dried.

Specific Challenges

Communications The Kitchen Robotics system required that the UniStream PLC connect to the cloud and execute commands in real time; this required the team to create an API and implement a dedicated TCP-IP protocol, using several ports simultaneously. In addition, the different system components used different protocols, both standard and dedicated—the UniStream PLC needs to communicate with over 60 components such as servos, VFDs, heaters, sensors, steppers, etc.

Servo Motion The different axes of motion relied on linear and rotary actuators and other dedicated mechanisms. The force of each axis had to be modified in real-time, while the system was running. Each axis, edge sensor, mechanical brake, etc. required a different homing method.

In addition, there were issues of overlap—this was handled by using absolute encoders to check the current position before the start of any movement and to change the speed of movement of each axis accordingly while mapping the current position throughout the movement. This enabled the system to achieve high levels of both efficiency and safety.

Steppers By controlling the steppers via communication, the team was able to reduce costs by avoiding the complex wiring and integration that such a large number of steppers would otherwise require.

Benefits of using Unitronics

Kitchen Robotics selected Unitronics not only because the products filled all of the necessary requirements—they also recognized the advantages of Unitronics All-in-One Solution, which enabled them to easily obtain all control components for their complex Motion application from a single supplier: PLCs and HMIs, servo drives and motors– all seamlessly supported, commissioned, and programmed in UniLogic software.

The Unitronics approach to motion, Servo Made Simple, enabled them to define axes, implement control, analyze, and track processes, while Unitronics motion experts were available to aid them throughout the project.
