Chef Robotics Inc. yesterday introduced Chef+, which it said is its most advanced meal-assembly robot yet. The San Francisco-based company said it is an innovator in artificial intelligence-enabled meal assembly for the food manufacturing industry.
Built on insights from more than 80 million servings in production, Chef+ delivers reliability, double the ingredient capacity, a reduced footprint, improved food safety, and enhanced usability and performance compared with previous models, said Chef Robotics.
The company raised $43 million earlier this year in Series A funding. It has used that investment to expand its business and innovating with new capabilities, such as those in Chef+.
Chef+ address operational constraints
Food manufacturers face critical operational constraints: Limited production floor space restricts equipment placement, frequent ingredient refills disrupt production throughput, and stringent food safety standards demand easy-to-clean equipment.
Chef+ is explicitly engineered to address these challenges through advancements in six key areas:
- Doubled ingredient capacity: Ingredient pans are twice the volume of previous models, significantly extending the time between refills. This allows refill runners to load ingredients less frequently, reducing labor touchpoints and increasing productivity. The increased capacity is particularly beneficial for low-density and voluminous ingredients, such as leafy greens, and for large portion deposits, such as pasta.
- Reduced footprint: Despite its doubled capacity, Chef+ maintains the same footprint as a worker. This thinner design allows facilities to deploy robots in tight spaces and place two production lines back to back, optimizing valuable floor space, according to Chef Robotics.
- Enhanced reliability: Drawing on extensive runtime at customer facilities, Chef+ features integrated electrical enclosures that conceal all wiring in sealed tubes, increasing mean time between failures (MTBF). The robot features IP cameras, which are more reliable than USB-C cameras for cold production environments. Chef+ also includes an integrated water separator that captures excess moisture in pneumatic tubes, ensuring that air remains completely dry. It uses an array of dome antennas for improved Wi-Fi connectivity.
- Advanced food safety: The Chef+ frame replaces the two front closed tubes with an open-angle iron frame. This makes surfaces easier to clean and eliminates hidden crevices where residue can accumulate, helping manufacturers meet strict food safety and sanitation standards.
- Improved usability: Chef+ features several functions to enhance usability and reduce setup and changeover time. Ingredient pans slide easily into the robot, thanks to an integrated locking mechanism. P-CAP technology makes the touchscreen easier to use with gloves in cold production environments. In addition, a daisy-chain power configuration allows manufacturers to connect multiple robots to a single ceiling power source. Finally, Chef+ includes self-leveling feet and an integrated handle, making it easier to move around on the production floor.
- Enhanced performance: Chef+ delivers higher CPU and GPU processing power and adapts to variable ingredient types in real time, claimed Chef Robotics. It also includes a three-camera vision system to accurately track conveyor speed and trays for precise ingredient placement.
Chef+ has undergone rigorous testing in the company’s cold-room lab environment and is already running in production at several customer sites. The robot is now widely available to food manufacturers across the U.S., Canada, and the U.K.
New ‘pat down’ gripper attachment flattens food
Chef Robotics said its new “pat-down” capability takes on the manual task of flattening ingredients to ensure uniform tray coverage and improved sealing. By automating this repetitive, labor-intensive process, manufacturers can enhance meal presentation and reduce costs while addressing critical labor shortages.
The new capability fully automates meal-flattening tasks using vibration technology in the end effector along with a flat, cross-slotted utensil. This new utensil is interchangeable with Chef’s depositing utensils and features a cleanable, rounded-edge design that meets food safety standards and cleaning protocols.
The solution employs AI-powered computer vision software to detect and track trays on the conveyor in real-time, understanding their position and orientation. This capability enables the robots to handle variations in tray positions, line stoppages, and speed changes that traditional automation cannot manage, asserted Chef Robotics.
For high-volume operations, the pat-down capability integrates with Chef’s robot-to-robot (R2R) system, enabling multiple robots to coordinate and distribute tasks by alternating trays for increased throughput. Production lines can also use robots for both meal assembly and pat-down operations simultaneously, with one robot depositing ingredients while another flattens meals.
The pat-down capability eliminates a strenuous, repetitive task, freeing up workers for higher-value tasks while reducing overall production costs and preventing repetitive stress injuries. Beyond labor cost reduction, the solution addresses downstream operational challenges such as spillage during sealing, machine downtime, rejected trays, and food waste.
Some Chef customers have already deployed the pat-down capability on their production lines, ensuring consistent presentation and tray sealing for frozen meals such as mac and cheese. The capability is now widely available to food manufacturers in the U.S., Canada, and the UK. As part of Chef’s robotics-as-a-service (RaaS) pricing model, the capability requires no upfront capital investment.
