Module mbot 

mBot2 reference sensor vocabulary.

The mBot2 is a programmable robot by Makeblock, retailing for around $50–$80 USD. It runs a CyberPi microcontroller with onboard light, sound, and motion sensors.

This module provides a ready-to-use SensorVocabulary implementation for the mBot2’s six onboard sensor dimensions. It is the vocabulary used in the CCF reference demo — the same robot that demonstrates emergent social behaviour through accumulated experience, entirely on-device with no cloud or ML model required.

Why this exists

The mBot2 demo is the existence proof for what ccf-core makes possible: a sub-$100 robot that develops genuine context-sensitive social behaviour. Not scripted. Not rule-based. The trust field accumulates through real interaction, and the robot’s responses emerge from what it has actually experienced in each environment.

This module ships as a concrete reference so you can see exactly what a production SensorVocabulary implementation looks like. Your own hardware vocabulary follows the same pattern — just swap in your sensor dimensions.
