Zumo Robot 2040 assembled with 75:1 High Power motors
The Zumo 2040 is a tracked robot that is customizable and programmable. With 160 gr (275 gr with batteries), this robot measure less than 10 cm. As such it can participate to Mini-Sumo battle competition but can also do much more.
This Zumo 2040 robot is contrôled with Pi RP2040 microcontroller (identical to the famous Raspberry Pi Pico), a dual-core Arm Cortex-M0+ processor running at 125 MHz programmed with C, C++, Arduino, or Python. The Zumo 2040 is fitted with 16 Mio of flash memory and preloaded with MicroPython (Python for MicroControler). Just plug the USB-C cable and you are ready to explore the available Python code examples. The robot can also be customized with with additional peripherals and sensors. The Zumo 2040 provides power rails and I/O lines in various places of the board. The 4-pin JST SH connector (Qwiic/StemmaQT) ships an easy to wire I2C bus, great to connect Sparkfun Qwiic and Adafruit STEMMA QT devices.
The Zumo 2040 features two H-bridge motor drivers and many sensors. The quadrature encoders would be great for closed-loop speed control of the motor, the inertial measurement unit is made of 3-axis accelerometer, magnetometer and a gyroscope. The front side of the robot are fitted with a downward-facing reflectance sensor array (5 sensors) allowing line-following and edge-detection. The additional proximity sensors are present on the side and the front of the robot, they are great for object or wall detection.
The user interactions have many interface: 3 onboard pushbuttons, a 128×64 graphical OLED display, a buzzer and 6x RGB LEDs. A lor of possibilities there.
This Zumo 2040 exists in the 3 différents gearbox ratio:
- Assembled with 50:1 HP motors : highest speed and lowest torque of the three options
- Assembled with 75:1 HP motors : average speed and torque (this product)
- Assembled with 100:1 HP motors : highest torque and lowest speed
| Gear Ratio | Free-Run @ 6V | Stall Torque @ 6V | Stall Current @ 6V | Top Speed @ 6V and 500 gr |
| 50:1 HP | 625 RPM | 10.59 N-cm | 1600 mA | 100 cm/s |
|---|---|---|---|---|
| 75:1 HP | 400 RPM | 15.53 N-cm | 1600 mA | 65 cm/S |
| 100:1 HP | 320 RPM | 21.18 N-cm | 1600 mA | 50 cm/s |
Please note that 4xAA batteries are required to make this product working.
