The highly integrated Zumo 32U4 OLED is our newest Zumo robot. It improves upon the original Zumo 32U4 robot by replacing the 8×2 character LCD with a 128×64 graphical OLED display. Enhancements over the even older Zumo robot for Arduino include a built-in Arduino-compatible ATmega32U4 microcontroller, encoders for closed-loop motor control, and proximity sensors for obstacle detection. The robot is compact enough to qualify as a mini sumo robot, but its high-performance motors and integrated sensors make it versatile enough to serve as a general-purpose small robot.

The video below shows just a few of the many fun things you can do with an unmodified, stock Zumo 32U4 robot. It shows the original Zumo 32U4, but the newer Zumo 32U4 OLED is capable of the same things:

We are very excited to announce that the 3pi+ 32U4 OLED Robot is now available! This is an updated version of the original 3pi+ 32U4 Robot that replaces the old LCD with a monochrome 128×64 OLED display, giving it the ability to display fancy high-contrast graphics while following a line course, navigating a maze, or doing whatever it is that you want this compact but versatile mobile platform to do.

For more than 16 years, starting with some of our oldest products (from well before I joined Pololu), we have used HD44780-compatible alphanumeric liquid crystal displays on our robots and robot controllers. These LCDs have been around forever and are limited to displaying simple text on a fixed grid, but they are also ubiquitous: there are plenty of manufacturers still making displays that use the standard HD44780 interface.

It’s unlikely that we would have much difficulty sourcing this kind of display any time soon (as long as the pandemic doesn’t mess things up too badly), so using them in our products has always been a safe option despite their graphical limitations. The original 3pi+ 32U4 that we released late last year was our most recent design to include LCD support.

Meanwhile, monochrome organic light-emitting diode (OLED) displays have become increasingly popular in electronics over the last decade or so, and it’s not hard to see why: you can draw graphics on them, they can fit more information on the screen, they’re easier to read in the dark, and they just plain look cooler. But even though you might be able to go to eBay or Amazon and order a cheap OLED display for your project when you want one, it’s critical that we find a dependable supplier for a component like this before we can start to design it into our products.

That is why the availability of the 1.3″ OLED module we announced recently was actually a pretty big deal for us: it means that we finally have a source that we can rely on for larger quantities of these displays. The 3pi+ 32U4 OLED is the first of what we hope will be many robots and control boards that make use of the graphical capabilities offered by an OLED screen.

For anyone who wants to use different motors than the options above, the 3pi+ 32U4 OLED control board is likewise available separately and can be combined with a 3pi+ chassis and a pair of motors to build a custom robot.

We will be phasing out the original 3pi+ 32U4 robots and kits (they will remain available by special order), but that does not mean the old versions are suddenly obsolete or that you will have to learn an entirely new platform to use the new OLED version. Aside from the display interface, the hardware on the LCD and OLED versions is exactly the same, with features including encoders, line sensors, front bump sensors, and a full IMU (inertial measurement unit).

From a software perspective, it can actually be pretty challenging to work with graphics, especially on a small processor like the ATmega32U4. The simplicity of a text LCD can be an advantage in that you can essentially just ask it to do something like printing the letter “A” on the first column of the second row. On a graphical display, even if you just want to show some text, you have to define the shape of the letter in pixels; optionally composite that shape into a memory buffer; and then send the complete pixel data to the display. That means you have a lot more control over how that letter “A” is shown, but it takes a lot more work to do it.

To help get you started, we’ve developed an LCD compatibility layer as part of our Arduino library for the 3pi+ 32U4. This makes it easier to use the OLED screen for common display tasks, and it’s straightforward to write programs that will work on either version of the robot with minimal changes, since you can update an existing program to run on the OLED version by changing just a single line of code.

We plan to continue improving our libraries to give you more options for efficiently working with both text and graphics on an OLED display; stay tuned for updates!

In many ways, this new version is just like the original Zumo 32U4: it’s a versatile tracked robot designed to be a capable Mini-Sumo competitor, but with enough sensors and extra features to enable lots of other applications. The Zumo 32U4 OLED adds to that versatility by replacing the original LCD (liquid crystal display) with a high-contrast graphical OLED display. With this monochrome 128×64 screen, you can present high-density data displays to help you analyze the Zumo’s status and sensor readings, or you can add some flair to your Zumo by showing eye-catching graphics.

We’ve updated our Arduino library for the Zumo 32U4 to add OLED display support as well as an LCD compatibility layer (the same way we did for the 3pi+), letting you easily convert existing programs to run on the OLED version or write new programs that will work on both old and new robots.

As with the LCD version, the new Zumo 32U4 OLED robot is available as a kit (with motors not included so you can select your own to customize performance) or as a fully assembled robot with your choice of 50:1, 75:1, or 100:1 motor options

Our store offers several versions of the Pololu Zumo set to pass and all the necessary additional elements. The construction work is at first glance reminiscent of the robots of classes mini-sumo. The platform moves on tracks, driven by two micro motors with gear box (version with double-shaft), selection of which depends on which way you want to balance the compromise between speed and torque; the higher the maximum speed the job, the less force that can fight the enemy. In the shop you will find several versions of the motors corresponding to the robot so you can decide for yourselves if you rely on high speed or great strength. Regardless of the choice of drives, self-installation is simple and fast, and in its result, there will be a slim design, ready to tackle all the tasks you put in front of the robot. Combat capabilities of the little warrior significantly increases optimized, a metal plug where the robot will challenge and spychał other dojo.

The Pololu A-Star 32U4 Prime is a general-purpose programmable board based on the ATmega32U4 AVR microcontroller from Microchip (formerly Atmel) and arranged in the common Arduino form factor exemplified by the Uno R3 and Leonardo. As such, the A-Star Prime (abbreviated A* Prime) is compatible with many Arduino shields, including all of the Arduino shields we carry. All 26 of the microcontroller’s GPIO lines are accessible on the board, including seven than can be used as PWM outputs and twelve that can be used as analog inputs. The ATmega32U4 is capable of native full-speed USB, which makes it more versatile than similar boards that rely on USB-to-serial adapters: in addition to supporting a virtual (CDC) serial/COM port interface, the A-Star can appear to a connected computer as a mouse and keyboard. The A-Star’s USB interface can be accessed through its USB Micro-B connector.

All 26 general-purpose I/O lines from the ATmega32U4 are broken out (including PB0, PD5, and PE2); 7 of these can be used as hardware PWM outputs and 12 of these can be used as analog inputs

This configuration of the A-Star 32U4 Prime SV includes microSD support and is assembled with through-hole components as shown in the picture above so that all the basic features can be used without any additional soldering. The standard female headers common to many Arduinos are preinstalled, as is the 2×3 male ISP header, 2×7 male LCD connector, buzzer, DC power jack, and shorting block headers for enabling the microSD hardware, buzzer, and battery voltage monitor. A removable 8×2 character LCD is included with this configuration, and a preinstalled 2-pin terminal block provides an alternate way of supplying input power to the board. This is the SV version of the A-Star Prime, which operates from 5 V to 36 V.

A major feature of the A* Prime SV is its power system, which allows it to efficiently operate from a 5 V to 36 V external source. The input voltage is regulated to 5 V by an ISL85410 switching step-down (buck) converter from Intersil, a higher-power version of the ISL85418 used on the smaller A-Star 32U4 Mini SV. (We also make a standalone regulator based on this integrated circuit.)

The A-Star 32U4 Prime ships with a preloaded Arduino-compatible bootloader (which uses 4 KB of flash memory, leaving 28 KB available for the user program). We provide a software add-on that enables the board to be easily programmed from the Arduino environment and an Arduino library to make it easy to use the additional on-board hardware. The A-Star 32U4 has the same microcontroller and form factor as the Arduino Leonardo, and it runs at the same frequency, so we generally expect it to work with shields that are compatible with the Leonardo and similar boards. Note that the Prime has additional components and connection points, so you should make sure these do not physically interfere with any shield you are considering using. The following table shows how the Prime compares to the Leonardo and Uno:

Like the A-Star 32U4 programmable microcontrollers, the Romi 32U4 Controller Board is powered by by the USB-enabled ATmega32U4 AVR microcontroller (Microchip, formerly Atmel). The 32U4 is preloaded with an Arduino-compatible bootloader. The controller board features two H-bridge to drive motors and is designed to connect to a Romi Encoder Pair Kit (available separately). This combination allows to build a closed-loop motor control. The board includes a powerful 5 V switching step-down regulator that can supply up to 2 A continuously. The board also have a versatile power distribution circuit. A 3-axis accelerometer and gyro enable a Romi 32U4 robot to make inertial measurements, estimate its orientation, and detect external forces.

Its 2x20 pins on-board connector (and mounting holes) can be used with a Raspberry Pi (Model B+ or newer, including Raspberry Pi 3 Model B+ and Model A+, or Raspberry-Pi compatible). The Pi is plugged directly into the control board. The level shifters placed on the board mke it easy to setup an I²C communication and interface other signals between the two controllers (ROMI 32U4 board and the Pi). The ROMI 32U4 contoller will supplies 5 V power to an attached Raspberry Pi.

In the setup ROMI 32U4 Controller + Raspberry Pi, the Raspberry-Pi handle a PiCamera + high-level robot control and sends commands to the Romi 32U4 Controller Board to manage low-level tasks (running motors, reading encoders, interfacing additional sensors and analog devices).

To ease the connection of sensors and devices, the I/O lines of both the ATmega32U4 and the Raspberry Pi are broken out along the front and rear of the control board (2.54mm) and the board power rails are similarly accessible.

For each order, you will receive a 32U4 Control Board ships with all of its surface-mount components populated, and it includes a number of through-hole parts and mounting hardware, as shown in the picture above.

The Romi chassis itself and other parts required to build a complete Romi 32U4 robot are not included; these are listed below, along with some optional additions.

The "Motor Driver and Power Distribution Board for Romi Chassis" includes the same motor drivers and power circuit (including 5 V regulator) as the Romi 32U4 Control Board, but offers you flexibility in choosing and connecting your own microcontroller.

A software add-on is available that makes it easy to program a Romi 32U4 robot from the Arduino environment, and we have Arduino libraries and example sketches to help get you started. A USB A to Micro-B cable (not included) is required for programming.
