One operator moves a wheeled base and controls both arms while the system records demonstrations; imitation-learning methods can then use that data to perform tasks autonomously.
What Mobile ALOHA is designed to do
Mobile ALOHA extends the ALOHA bimanual platform with a wheeled mobile base and a whole-body teleoperation interface. Its purpose is to collect demonstrations of tasks that require a robot to move through an environment while using both arms. The system was presented by Zipeng Fu, Tony Z. Zhao and Chelsea Finn in 2024 as a low-cost research platform for learning complex mobile bimanual manipulation.
“Whole-body” refers to coordinating the mobile base with the two arms, rather than operating a fixed tabletop robot. The operator controls the system directly, and the resulting demonstrations provide examples that can be used to train a robot policy through imitation learning.
How the teleoperation and recording work
One operator controls the base and both arms
The operator is physically tethered to the mobile base, backdrives its low-friction wheels, and uses both hands to control the arms. This arrangement lets a person demonstrate tasks that combine movement around a space with two-handed manipulation.

The action data combines arm and base motion
Each recorded action is represented as a 16-dimensional vector: 14 arm-joint positions plus the base’s linear and angular velocity. The implementation streams arm proprioception over USB serial and mobile-base data over CAN bus. In practical terms, the demonstration records both what the arms do and how the base moves, so the learned behavior can coordinate them.
What the published demonstrations show
The Mobile ALOHA project page and the 2024 paper describe autonomous task demonstrations in kitchens and other indoor settings. Examples include:

| Capability | Reported value |
|---|---|
| Vertical reach | 65 cm to 200 cm |
| Extension beyond the base | 100 cm |
| Object lifting | Objects weighing up to 1.5 kg |
| Pulling force | 100 N at a height of 1.5 m |
These are capabilities reported for the research system, not guarantees for every build or task. The paper says most task success rates were calculated from 20 evaluation trials; Cook Shrimp was evaluated over five trials. Those trial counts matter when interpreting demonstrations as evidence: they describe controlled evaluations, not long-term household reliability.
Demonstrations and co-training
The project authors report that, with 50 demonstrations for each task, co-training with static ALOHA data can increase success rates by up to 90%. This is a reported maximum, not a promise that every task will improve by 90%: the result is tied to the authors’ training setup and evaluated tasks.

Operator learning time in a small study
The paper also reports a user study with eight computer-science graduate students. After five trials, average completion time for Wipe Wine fell from 46 seconds to 28 seconds, while Use Cabinet fell from 75 seconds to 36 seconds. These figures describe that study’s participants and tasks; they do not establish how quickly all operators will learn the interface.
What hardware and software a build requires
The repository setup notes identify a three-camera configuration, four robot arms, and an AgileX Tracer mobile base. Reproducing the system therefore means assembling and calibrating several components, not simply installing an app or buying one packaged robot.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to approach reproducing Mobile ALOHA
- Start with the official project resources. The Mobile ALOHA project page links to the paper, tutorial, datasets, hardware code, and machine-learning code. Use those materials to identify the intended build and learning workflow.
- Assemble the documented hardware. Plan for the Tracer base, four arms, and three cameras, plus the required cabling and computing. The project page, paper, and repository setup notes do not establish a verified retail bundle.
- Set up the base connection on Linux. Use the repository’s instructions for the stock CANBUS-to-USB cable and AgileX SDK, then enable gs_usb and configure can0 at the documented 500000 bitrate.
- Install the software environment and verify devices. Follow the repository’s Linux/ROS and Python guidance, and run its device-connection checks before attempting data collection.
- Calibrate and collect demonstrations. Configure the teleoperation system so the operator can control the base and both arms while recording the combined action data. Calibration details and compatible component choices should come from the current tutorial and code rather than assumptions based on the high-level summary.
- Train and evaluate against specific tasks. Use the project’s machine-learning code and datasets as appropriate, and evaluate performance on the task and setup you actually care about. The reported demonstration counts and success rates should not be treated as universal predictions.
Is Mobile ALOHA a consumer robot you can buy?
The cited project materials describe an open research assembly and provide links to code, tutorial material, and datasets. They do not establish a turnkey consumer product, a verified retail bundle, safety certification, or a current retail price. Someone interested in building it should treat the project as a robotics integration effort and check current component availability and repository instructions.
How to compare it with other robot-learning platforms
Mobile ALOHA is most usefully compared with platforms by the capability and evidence each actually provides, rather than by a broad label such as “household robot.” Check these dimensions:
Quick Recap
- Manipulation: Does the platform support bimanual work, or only a single arm?
- Mobility: Can it coordinate a mobile base with manipulation, or is it fixed to a tabletop?
- Teleoperation: How does the operator control the robot, and what evidence is available about learning time or ergonomics?
- Training data: How many demonstrations are used for useful performance, and are additional datasets or co-training part of the result?
- Physical capability: What reach, payload, or pulling-force measurements are reported, and under what evaluation conditions?
- Openness: Are hardware details, datasets, and software available, and are they sufficient to reproduce the system?
