Mobile ALOHA

What is Mobile ALOHA?

Mobile ALOHA is a robotic system designed to learn complex bimanual mobile manipulation through human demonstrations. It extends the ALOHA robot setup with a wheeled mobile base and whole-body teleoperation, allowing an operator to control two robotic arms and the base together. The system captures these demonstrations and uses imitation learning to teach robots tasks that require coordinated movement, navigation, and object manipulation. Mobile ALOHA has demonstrated skills including cooking, opening cabinets, entering elevators, handling cookware, cleaning, and other household activities. Its research focuses on making mobile manipulation more accessible by combining low-cost hardware, teleoperation, collected datasets, and learning-based control.

Mobile ALOHA was developed by Zipeng Fu, Tony Z. Zhao, and Chelsea Finn, with Fu and Zhao serving as project co-leads. The research uses 50 demonstrations per task and reports success-rate improvements of up to 90% through co-training. Its action representation combines 14 degrees of freedom from the robot joints with 2 mobile-base velocity dimensions, creating a 16-dimensional action vector. The supporting static ALOHA dataset contains 825 episodes. The project was published at CoRL and later appeared in PMLR in 2025.
