AgileX Cobot Magic teleoperation: buying a Mobile ALOHA rig, and staffing the people who drive it

Cobot Magic packages Stanford's Mobile ALOHA design, the robot that learned to cook shrimp and rinse a pan from human demonstrations, as a rig you can order. The hardware is the easy part. The demonstrations still need people.

Updated

AgileX Cobot Magic is a commercial build of Mobile ALOHA, the open-source system from Stanford that put a two-armed teleoperation rig on a mobile base and trained it to do kitchen and household tasks from human demonstrations. AgileX swaps in its own Tracer base and arms, adds an industrial PC and cameras, and integrates the Mobile ALOHA code. For a lab or a home-robot startup, it answers one question quickly: how do I get a bimanual mobile rig that records learnable demonstrations without building one? It leaves a second question open: who will drive it, for how many hours, and how consistently?

What Mobile ALOHA showed

The Mobile ALOHA paper by Zipeng Fu, Tony Z. Zhao and Chelsea Finn (January 2024, CoRL 2024) describes a system that "augments the ALOHA system with a mobile base, and a whole-body teleoperation interface." The headline result, from the project page: "With 50 demonstrations for each task, co-training can increase success rates by up to 90%", where co-training means mixing the new mobile demonstrations with existing static ALOHA datasets. The robot then performed tasks such as sautéing and serving a piece of shrimp, opening a two-door wall cabinet to store heavy pots, calling and entering an elevator, and rinsing a used pan under a faucet.

Fifty demonstrations per task is the number that matters for anyone budgeting a home-robot data program. It is small enough that a trained operator can record a task's worth in a session or two, and large enough that quality and consistency across those 50 decide whether the policy works. The Mobile ALOHA code is public under MIT: MarkFzp/mobile-aloha holds the teleoperation and recording scripts, tested on ROS 1 Noetic, with its record_episodes.py script saving each episode as an HDF5 file, and the learning code lives in act-plus-plus, a fork of the original ACT repository. Teleop starts when the operator closes the leader gripper.

What AgileX sells

AgileX's Cobot Magic page calls it "an open-source robotic system that uses Mobile ALOHA for controlling both a mobile base and a robotic arm", credits the Stanford authors, and says it integrates the Mobile ALOHA code with an environment for data collection and model training and support for VLA frameworks and world models. The hardware is built on four arms, two wrist cameras and one top camera, on AgileX's Tracer differential-drive base. AgileX's 2024 write-up on Open Robotics Discourse gives more detail on that build:

Arms

Four 6-DoF lightweight arms customized by AgileX, where the original Mobile ALOHA used ViperX 300 arms. The operator controls the working arms through "teaching" arms.

Base

The Tracer, an indoor differential-drive base, controlled together with the arms for whole-body data collection.

Cameras

Three Orbbec Dabai depth cameras in the 2024 configuration, in the wrist-and-top layout of the original design.

Compute

An industrial PC is required, either a Jetson Orin Nano 8 GB developer kit or an APQ-X7010 with an RTX 4060, i7-9700 and 32 GB of memory.

Data

Recordings capture the positions of 14 arm joints over time, plus two base degrees of freedom, for imitation learning by behavior cloning. The setup clones AgileX's act-plus-plus fork of the ACT codebase.

Extras

An IMU, an 11.6 in 1080p display, an ALOHA stand and a 1,000 W portable power station.

Current listings differ in detail from that 2024 build. European reseller Generation Robots lists Cobot Magic with AgileX PiPER arms (6 DoF, 626 mm reach, 1.5 kg payload), a top speed of 1.6 m/s, a four-hour charge time and delivery within two months. Confirm the exact arm, camera and computer configuration with AgileX when you request a quote.

AgileX also publishes mobile_aloha_sim, URDF and Xacro models of Cobot Magic and its split-type ALOHA variants, so teams can rehearse tasks and test code in simulation before booking robot time.

How a Cobot Magic session works

1. Set the scene

Stage the task the same way each episode: objects in their start positions, robot at a fixed start pose, cameras checked.

2. Drive with the leader arms

The operator moves the teaching arms and the follower arms copy them joint for joint, while the base is driven through the same session so arm and base motion are recorded together.

3. Record

Joint positions, base motion and the three camera streams are logged with one clock. Each episode ends with a success or failure label.

4. Reset and repeat

Reset the scene, repeat with the same strategy. Fifty clean episodes of one task beat 200 messy ones.

5. Train and evaluate

Train an ACT-style policy, optionally co-trained with existing static ALOHA data as in the paper, then run it on the robot and record its failures as the next round of targets.

Leader-follower rigs make the operator's motion the training signal, joint for joint. That is why they produce such learnable data, and also why operator habits show up directly in the policy: a hesitation, a regrasp or a wide approach gets copied. Training operators to a single protocol is not polish; it is most of the data quality.

What a good Cobot Magic operator does

Moves base and arms in a planned order. A differential-drive base cannot slide sideways, so the approach angle to a counter or cabinet has to be set before the arms reach.
Keeps both arms purposeful. An idle follower arm drifting into a camera view is noise the policy will learn.
Uses one grasp and one approach per task, across every episode and every operator on the shift.
Respects arm payload limits (Generation Robots lists PiPER arms rated at 1.5 kg) and stops rather than forcing heavy pots or stuck doors.
Labels failures honestly, including the near misses, and resets the scene the same way every time.
Flags drift: a wrist camera knocked out of alignment or a gripper starting to slip can ruin a day's episodes if nobody notices.

Data: formats and public sets

The Mobile ALOHA research data has been ported to LeRobot. lerobot/aloha_mobile_shrimp, for example, holds 18 episodes and 67,500 frames at 50 fps with a high camera and two wrist cameras at 640 × 480, in LeRobot v3.0 format under Apache-2.0. It is a good reference for structuring your own Cobot Magic episodes, even though the arms differ. If your stack expects HDF5 or RLDS, decide at the start which is the master format and convert from it, rather than recording in two. Our data collection guide covers episode structure and quality checks.

Buy a teleop rig or hire operators?

This is the decision Cobot Magic forces, and it is really two decisions. The rig is a capital purchase with a known lead time. The operator hours are a running cost, and for most teams they become the larger and harder one to manage. The trade-offs:

In-house operators

Full control and fast iteration, but researchers spend their days recording rather than training, and output drops when they are busy. Consistency across several part-time operators is hard to keep.

A managed operator team

A dedicated group trained on your rig and protocol records on a schedule, including hours your researchers are not working. You keep task design, review and training; they keep the throughput and the consistency.

A mix

Researchers define each new task and record the first episodes; a trained team records the rest of the 50 and the corrections after each evaluation round.

The figure to track either way is clean episodes per operator hour, measured on your rig and your task, because it converts directly into what each skill costs to teach.

Latency and remote operation

A leader-follower rig is normally run with the operator in the room, holding the leader arms. Running one from another site means a second set of leader arms at the operator's station, a low-latency video link from the robot's cameras, and a local safety layer that stops the arms and base on a lost connection. For tabletop pick-and-place a regional link works; for fast contact tasks like the shrimp-flipping demo, the operator should be close. Our teleoperation latency guide has budgets by task.

A note for US buyers

On July 28, 2026 the FCC added "Foreign-produced advanced robotic devices, except advanced robotic devices which have been granted a Conditional Approval by DoW" to its Covered List (FCC public notice DA 26-786), and covered equipment cannot receive new FCC equipment authorizations. The notice defines the category by reference to an attached national security determination, and we have not seen the FCC or AgileX say how it applies to Cobot Magic. Ask AgileX or your reseller about authorization status before ordering for a US lab.

Cobot Magic against other Mobile ALOHA-style rigs

The closest alternative is the Trossen ALOHA Mobile AI. Trossen lists it at $33,695.95 without a laptop on its Mobile AI page as of October 2026, with two leader-follower pairs of WidowX AI arms, three RealSense D405 cameras and LeRobot among its supported software. Cobot Magic uses AgileX's own base and arms, and AgileX makes the PiPER arm as a separate product for teams building their own rigs. For a larger wheeled platform with a lifting torso and an open household dataset, see the Galaxea R1 Lite.

How RoboPilots staffs a Cobot Magic program
