Solving the Challenge of Safe, Reliable Food Preparation with Wolff Electronic Design’s Electro-Mechanical Control System


A client come to us with the challenge of designing a system that could reliably and safely prepare food using robotics for commercial restaurant. They needed a solution that would reduce the complexity of cooking and ensure hot food was always prepared safely, regardless of the skill level of the labor force in the kitchen and today’s tight labor market. The product needed to be easy to train staff to use without unnecessary or complicated instructions, one that helps ensure food safety, quality and satisfaction. Minimal maintenance and high reliability were also key components to the design outcome.

Project Details

To address these challenges, Wolff Electronic Design designed an electro-mechanical control system that incorporates motor controls, robotics, strain gauges, thermostatic controls, custom HMIs and cost-optimized embedded systems.

With a goal of designing the system for ease of use and quick training, Wolff Electronic Design incorporated Qt for the graphical user interface, 32-bit micro controllers, and embedded Linux. Separate PC boards were used, all communicating over CAN and Ethernet networks. The system is highly reliable, with minimal maintenance required, making it an excellent choice for low-skilled labor.

Our design process followed industry best practices, with a focus on risk-based development processes similar to the way the FDA has updated its requirements for medical device development. Wolff Electronic Design adhered to appropriate design processes and traceability processes required by the FDA to ensure the highest quality product.

QT, a software library for creating graphical user interfaces, was used to make the system easy to use. It was initially developed for “candy-bar” phones, but it has since evolved to be used in a wide range of devices, including industrial touchscreens and desktop software.
