DESCRIPTION
RETIRED PRODUCT – We’ve stopped stocking this product or it has been retired by the manufacturer and is no longer for sale. This page remains available for its resources and as a source of potential interest.
The 3pi+ 32U4 is a versatile, high-performance, user-programmable robot that measures just 9.7 cm (3.8″) in diameter. At its heart is an ATmega32U4 AVR microcontroller from Microchip (formerly Atmel), and like our A-Star 32U4 programmable controllers, the 3pi+ 32U4 features a USB interface and ships preloaded with an Arduino-compatible bootloader, so all you need to program it is a USB A to Micro-B cable (not included). A software add-on is available that makes it easy to program the robot from the Arduino environment, and we have Arduino libraries and example sketches to help get you started. For advanced users who want to customize or enhance their robots with additional peripherals, the robot’s power rails, power system controls, and microcontroller’s I/O lines can be accessed via several 0.1″-pitch expansion ports.
The 3pi+ (or 3𝜋+) features two H-bridge motor drivers and a variety of integrated sensors, including a pair of quadrature encoders for closed-loop motor control, a complete inertial measurement unit (3-axis accelerometer, gyro, and magnetometer), five downward-facing reflectance sensors for line-following or edge-detection, and left and right bump sensors along the front face of the robot. Three on-board pushbuttons offer a convenient interface for user input, and an LCD, buzzer, and indicator LEDs allow the robot to provide feedback. The robot also features a unique power system that runs the motors at a constant 8 V independent of the battery charge level, so the speed of the motors does not vary with the battery voltage.
FEATURES
- ATmega32U4 microcontroller with Arduino-compatible bootloader can be programmed directly through a USB connection
- Quadrature encoders on both motors for closed-loop position and speed control
- Full 9-axis IMU (three-axis gyro, accelerometer, and compass)
- Bottom-loading battery holders keep batteries accessible even if additional levels are added
- Full wrap-around bumper to protect electronics from collisions
- Two bump sensors on the front
