AI robot arm builds meals and helps users with limited mobility

Engineers at Virginia Tech have developed an advanced robotic arm designed to assist people with limited mobility in performing everyday tasks, such as preparing meals. The system features adaptive grippers that combine rigid mechanics with soft, switchable adhesives, enabling the robot to handle a wide range of objects—from heavy items like metal pans to delicate ingredients like sprinkles. This innovation addresses the challenge that traditional robots face when gripping irregular or fragile items, by allowing the grippers to switch between strong adhesion and easy release. The robotic arm is controlled via a joystick-style interface, allowing users to guide the robot’s movements while artificial intelligence interprets and completes the tasks. This collaboration was demonstrated through complex activities like assembling a pizza, which involves handling diverse textures and shapes, and building an ice cream sundae with small, delicate toppings. Funded by over $600,000 from the National Science Foundation, the project aims to enhance independence for people with disabilities by making robotic assistance more intuitive and closely aligned with natural human motions.
