M5Stack StackChan
A small programmable desktop companion for makers exploring movement and interaction. It suits custom projects; useful behaviour depends on the controller, software and work you put in.

test track
Three proposed tasks. Ten attempts at each suitable task, with the outcome, time and human help recorded. Confirm the exact robot, software and safe setup first. These tasks are not evidence that this robot can do them.
Complete one documented learning activity
Proposed task. 0 of 10 attempts run.
Repeat the activity from the same starting setup

Pick a square to see what each attempt will record.
We will record the outcome, time, control mode, human help, safety stops, exact hardware and software, conditions and full video.
Proposed attempt; not run Only proceed if the exact unit supports the task and the setup is suitable. Keep remote control, scripted operation and autonomous operation separate. A completed attempt alone does not prove autonomy.What each square will show

Keep the conditions visible
Name the control mode, surface, object or prompt and every intervention. Ten attempts are an initial result, not proof of long-term reliability.

know?
Separate our own tests from published claims and the limits of the evidence. The counts below describe records, not performance or confidence scores.

What the evidence supports.
Capability and readiness are separate. These written findings are not a numerical rating or a physical test.
Capability
What can it actually do?
The specific maker claims and any independent observations are listed below. We have not run our own task tests on this robot.
Read the source-based assessmentReadiness
Could you use it in real life?
Intended use: Programmed desktop interaction. Dependable everyday use has not been established by the evidence reviewed. Distinguish factory software from community firmware. Extra controllers and expansion boards must not be assumed included.
Read the source-based assessmentA clear limit
This is a research profile based on the sources below, not a hands-on test. Maker claims remain attributed to the maker; they do not prove repeatable performance in your home or workplace.
02 / Can it actually do it?
The claims, with their context.
The wording below keeps each source’s limits. A demonstration, a maker’s claim and a repeatable real-world result are different things.
The robot body has two servo axes and a rechargeable battery; the maker describes app binding and several programming options.
Source 1M5Stack documents a factory setup using the StackChan World app and an M5Stack account for AI-agent configuration and remote video. Its setup uses Bluetooth pairing and 2.4 GHz Wi-Fi; it says 5 GHz is unsupported. These requirements apply to the documented factory firmware, not necessarily custom software.

Meet M5Stack StackChan
M5Stack’s StackChan is associated with SKUs K151 and K151-R. The open-source Stack-chan community project and alternative self-built configurations are related but not assumed identical; a remote-controller package is not a separate robot.

04 / Living with it
Right robot, right expectations.
What ownership could involve
Choose the exact hardware and whether the remote-controller bundle is included. M5Stack describes factory AI-agent, app video and remote-avatar functions; exact account and network requirements need confirmation. Other firmware can change behaviour. Check app support, firmware provenance, privacy, battery, UK supply and repair. It is described as a desktop robot; locomotion is not established. Camera and microphone functions merit household consent and data-handling review. M5Stack also documents Arduino and UiFlow2 development options; verify account, connectivity, privacy and firmware support for the exact software used.
Support, software and repairs
Official documentation includes Arduino/UiFlow, firmware restoration, calibration and hardware tests. The original core controller is required for the StackChan app; ordinary CoreS3 variants are not app-compatible replacements. The August 2026 LCD revision requires M5GFX 0.2.27 or newer. Unbind before switching XiaoZhi services. Confirm warranty and replacement-controller availability; avoid forcing powered servos.
Questions still open
What needs checking before you decide.
- No independent test of recognition, servo accuracy, software or cloud availability.
- Do not assume community firmware and factory features are interchangeable.
- Remote, expansion boards and other builds are not extra robots.
