The Balboa 32U4 balancing robot complete kit is a small, user-programmable balancing robot based on the Arduino-compatible ATmega32U4 AVR microcontroller and featuring two H-bridge motor drivers, quadrature encoders for closed-loop motor control, a full inertial measurement unit (3-axis accelerometer, gyro, and magnetometer) for estimating orientation and balancing, and an optional interface for connecting a Raspberry Pi to make a Raspberry Pi-controlled balancing robot.

The control board includes a powerful 5 V switching step-down regulator that can supply up to 2 A continuously, along with a versatile power-switching and distribution circuit. Three on-board pushbuttons offer a convenient interface for user input, while indicator LEDs, a buzzer, and a connector for an optional LCD (not included) allow the robot to provide feedback.

Using Raspberry Pi as a Controller

The Balboa 32U4 control board can serve as the robot’s main controller, or it can act a base for a more powerful Raspberry Pi controller. With the addition of a 2×20 female header and standoffs (neither of which are included), a compatible Raspberry Pi (Model B+ or newer, including Pi 3 Model B and Model A+) can plug directly into the board. Integrated level shifters make it easy to set up I²C communication and interface other signals between the two controllers, and the control board automatically supplies 5 V power to an attached Raspberry Pi. In this setup, the Raspberry Pi can handle the high-level robot control while relying on the Balboa’s ATmega32U4 microcontroller for low-level tasks, like running motors, reading encoders, and interfacing with other analog or timing-sensitive devices.

Balboa 32U4 features a USB interface with an Arduino-compatible bootloader. A software add-on is available that makes it easy to program the robot from the Arduino environment, there are Arduino libraries and example sketches to help get you started. A USB A to Micro-B cable (not included) is required for programming. For those who want to customize or enhance their robots with additional peripherals, the robot’s power rails and microcontroller’s I/O lines can be accessed via 0.1″-spaced through-holes along the sides, front/top, and back/bottom of the control board.

Note: This is a kit; assembly (including soldering) is required. Balboa runs on six AA batteries (not included).

Protecting against falls

When you are using the Balboa as a balancing robot, it is important to protect the electronics from hard falls that could damage them. In general, we recommend running the Balboa on soft surfaces, such as carpet, and it helps if you can install “arms” or simple bumpers that will hit the ground before the electronics.
