Bittle X

In homesShipped

A palm-sized, open-source robot dog kit you build in about an hour and program in blocks, Python or C++. It is a coding toy and teaching tool, not a helper: it walks, does tricks and answers voice commands, and an optional gripper lets it pick up light objects. Petoi says it has shipped more than 30,000 robots.

A dash means the maker has not published it. Values with a label are claims, not measurements.

Trust and legalWhat these mean

Does a remote human drive it?

Partly

Runs preset skills and offline voice commands; otherwise controlled by app or user code. Needs no network connection.

US FCC

Not applicable

At about 0.3 kg it is far below the 4.4 lb (2 kg) threshold in the FCC's 'advanced robotic device' definition, so the July 2026 Covered List rule does not apply. No whole-robot FCC ID found; radio is an ESP32 module.
