How It Works

The Rosmo robot functions as an integrated autonomous mobile platform centered around an ESP32 DevKit v1 microcontroller board. Power is supplied by an onboard battery/power supply system, which distributes appropriate voltages to the ESP32, motor drivers, and optional peripherals such as a Lidar sensor. The ESP32 acts as the central processing unit, executing firmware written in Arduino IDE, MicroPython, or Microblocks to process sensor inputs and manage high-level behavior, including ROS2 compatibility. Control signals are sent from the ESP32 to the motor drivers, which use passive components to help condition signals and drive the DC motors for locomotion. If an optional Lidar sensor is integrated, it communicates spatial data back to the ESP32, allowing the microcontroller to map or navigate the robot's environment. Because the system is designed for modular, solderless assembly via breakout boards and standard connectors, signals route cleanly between the power supply, processing board, actuation modules, and sensing elements, enabling rapid prototyping of autonomous robotic tasks.

Frequently Asked Questions

Do I need to know how to solder to build the Rosmo robot?

No, the robot is specifically designed for solderless assembly utilizing breakout boards, standard connectors, and modular components.

Which programming environments can I use to program the ESP32 on this robot?

You can program the ESP32 using the Arduino IDE, MicroPython, Microblocks, or interface it with ROS2 depending on your project requirements.

Is the Lidar sensor mandatory for the robot to function?

No, the Lidar sensor is optional; the core platform can be assembled and operated as a basic mobile robot without it.
