Tracks Mobility Module

Public notes about the Keero mobility module firmware, attribution, and open assets.

Tracks Mobility Module

The tracks module is the most concrete public firmware slice of Keero Bot today.

It is the part of the project that already bridges firmware, mechanics, wiring, and a clear mobility use case.

Why It Matters

This module is important because it shows that Keero Bot is not only a mainboard concept.

It already has a real path toward:

movement
embodied AI experiments
demoable physical interaction
repeatable module-level iteration

Attribution and Project Lineage

The mobility concept is inspired by the ESP-SparkBot direction.

Because of that, Keero keeps the mechanical references and public credits visible instead of pretending the module started from a blank page. The Keero contribution is the adaptation, firmware work, platform integration direction, and the updated controller approach.

What Is Keero-Specific

The current Keero tracks implementation is centered around:

Keero-authored open-source firmware
an updated module PCB direction using ESP32-C3-WROOM-M2
Arduino and PlatformIO compatibility
integration thinking that fits the broader Keero modular platform

In practice, that means:

the mobility idea acknowledges its inspiration
the working firmware and adaptation path are clearly Keero work

Firmware Scope

The public tracks firmware already demonstrates several real subsystems:

motion control
lighting control
battery and power monitoring
serial command parsing for testing and control

That is enough to present the module as active engineering work rather than a placeholder.

Reference Bill of Materials

The tracks module is documented here with practical reference parts that were used during bring-up and mobility testing.

This is not presented as a locked production BOM. It is a public reference set for developers who want to understand the module stack and mechanical direction.

Integration Notes

At a public level, the mobility module should currently be understood like this:

the mechanics follow the SparkBot-inspired tracked format
the Keero PCB/controller direction was updated around ESP32-C3-WROOM-M2
the module now fits an Arduino and PlatformIO workflow more naturally
the pogo connector provides a compact path for docking or module-to-mainboard connection

Prototyping Context

The tracks module also reflects the practical prototyping side of Keero Bot.

Its mobility direction, controller adaptation, and public hardware documentation were developed as part of the broader prototype effort supported by PCBWay. That support matters because modules like this benefit from repeated fabrication, testing, and iteration rather than a single static build.
