Dining robots significantly enhance the quality of life for individuals with upper limb motor impairments by enabling autonomous feeding. This paper systematically reviewed the technological evolution and representative products in this field, with a focused analysis of key technologies including kinematic modeling, trajectory planning, and intelligent control. Future development trends were also discussed, highlighting the need for innovative structural designs, optimized human-robot interaction, and deeper multi-source sensory fusion to advance the field toward more precise and human-like robotic feeding systems.
