The AiBlock Large Model Kit brings large AI models into a building block robotics kit. Its WonderMind AI module, built on an ESP32-S3 chip with a camera and a touchscreen, connects over Wi-Fi to the XiaoZhi AI platform, with support for Qwen, DeepSeek and Doubao. Learners build a robot tank on tracks in three official forms, then program it in Scratch blocks or Python to chat, describe what it sees, search for objects and carry out spoken commands. More than 530 enclosed ABS building pieces fit standard LEGO peg holes.

Zeta42 is an authorised Hiwonder partner in the Middle East.

What it does

Built for.

Multimodal large AI models
The WonderMind module runs on the XiaoZhi AI platform with Qwen, DeepSeek and Doubao support. It chats in more than 30 languages, perceives emotion, understands scenes, searches for objects and carries out complex commands.
From words to actions
Combined with the kit's sensors, the robot turns voice commands into physical actions, such as avoiding obstacles in real time or picking up a block of a named colour.
Three modes on one module
WonderMind switches between smart chat, vision interaction and an expressions mode that shows faces on its screen.
Three tank builds
More than 530 pieces build the Explorer Tank, the Gripper Tank and the Mechanic Tank, with illustrated print and digital guides. The parts also support builds of the learner's own design.
One cable for the sensors
Ultrasonic, light, and temperature and humidity sensors, an RGB LED module and a dot matrix module join over I2C in a single daisy chain, with unified 4-pin plugs that only fit one way round.
Scratch and Python
WonderLab offers Scratch block coding and Python text programming, so learners can move from one to the other as they progress.

Where it is used

Applications.

Introducing large language and vision models to primary and secondary learners
Embodied AI projects where spoken commands become robot actions
Sensor projects with distance, light, temperature and humidity readings
A first step from Scratch blocks to Python
