When evaluating a Robot Chef, prioritize Degrees of Freedom (DoF); a minimum of 6-axis movement is required for complex tasks like stir-frying or plating. Ensure the Payload Capacity matches your heaviest cookware (typically 3kg to 10kg). Look for High-Precision Sensors (torque and tactile) to ensure consistency in ingredient handling. Additionally, verify the Ingress Protection (IP) Rating, ideally IP67, to ensure the hardware can withstand high-temperature steam, oil splashes, and rigorous cleaning.
