Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/POLOLU-5013:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The Zumo 2040 is a highly integrated, user-programmable and customizable tracked robot. It measures less than 10 cm on each side and weighs approximately 275 g with batteries (160 g without), so it is both small enough and light enough to qualify for Mini-Sumo competitions, but its versatility makes it capable of much more than just robot sumo battles. At the heart of the Zumo 2040 is a Raspberry Pi RP2040 microcontroller (like the one on the Raspberry Pi Pico), a 32-bit dual-core Arm Cortex-M0+ processor running at 125 MHz, which can be programmed with C, C++, Arduino, or Python. The Zumo 2040 has 16 MB (128 Mbit) of flash memory that ships preloaded with a MicroPython interpreter, so you can get started right away by plugging into its USB-C port and editing the included example Python programs. For advanced users 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 and front of the main board. A 4-pin JST SH-compatible connector provides access to the RP2040’s I2C0 bus and can be used with many Sparkfun Qwiic and Adafruit STEMMA QT devices. | \| [![](https://core-electronics.com.au/attachments/localcontent/0J12338_46759a2b6a.jpg)](https://core-electronics.com.au/attachments/localcontent/0J12338_30416d0d44d.jpg) \| \|---\| \| Assembled Zumo 2040 robot, front view. \| | \| [![](https://core-electronics.com.au/attachments/localcontent/0J12330_69852fb143.jpg)](https://core-electronics.com.au/attachments/localcontent/0J12330_46008734dc8.jpg) \| \|---\|---\| \| Assembled Zumo 2040 robot, side view. \| | \| [![](https://core-electronics.com.au/attachments/localcontent/0J12331_52194debf1.jpg)](https://core-electronics.com.au/attachments/localcontent/0J12331_3573708a7af.jpg) \| \|---\|---\| \| Assembled Zumo 2040 robot, back view. \| | |---| The Zumo 2040 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 front- and side-facing proximity sensors for obstacle detection and ranging. Three on-board pushbuttons offer a convenient interface for user input, and a 128×64 graphical OLED display, buzzer, and six RGB LEDs allow the robot to provide feedback. | [![](https://core-electronics.com.au/attachments/localcontent/0J12361_12463a147d7.jpg)](https://core-electronics.com.au/attachments/localcontent/0J12361_30217c640ef.jpg) | |---| | Zumo 2040 Robot features, top view. | | [![](https://core-electronics.com.au/attachments/localcontent/0J12362_681125d72bb.jpg)](https://core-electronics.com.au/attachments/localcontent/0J12362_17859a8a078.jpg) | |---| | Zumo 2040 Robot features, bottom view. | The Zumo 2040 robot is available fully assembled with three different motor options (see the *Motors* section below for more information on how these different gear ratios perform): - [**Assembled with 50:1 HP motors**](https://core-electronics.com.au/zumo-2040-robot-assembled-with-501-hp-motors.html) — highest speed and lowest torque of the three options - [**Assembled with 75:1 HP motors**](https://core-electronics.com.au/zumo-2040-robot-assembled-with-751-hp-motors.html) — average speed and torque - [**Assembled with 100:1 HP motors**](https://core-electronics.com.au/zumo-2040-robot-assembled-with-1001-hp-motors.html) — highest torque and lowest speed The Zumo 2040 robot is also [**available as a kit**](https://core-electronics.com.au/zumo-2040-robot-kit-no-motors.html) (without motors) for those who would prefer to assemble it themselves or who want to use [different motors](https://core-electronics.com.au/category/141/micro-metal-gearmotors-with-extended-motor-shafts) than those in the three assembled versions. **Details for item #5013** This version of the Zumo 2040 robot (item #5013) ships fully assembled with a pair of [100:1 HP micro metal gearmotors (with extended motor shafts)](https://core-electronics.com.au/100-1-micro-metal-gearmotor-hp-with-extended-motor-shaft.html). As described above, two assembled versions are also available with lower gear ratios ( so Pololu are both faster but cannot deliver as much torque). | [![](https://core-electronics.com.au/attachments/localcontent/0J12327_4475895c559.jpg)](https://core-electronics.com.au/attachments/localcontent/0J12327_5166497465a.jpg) | |---| | Assembled Zumo 2040 robot. | You can use the following table to compare these three gear ratios in more detail. The first four columns are specifications of the motors themselves, while the last column is the measured top speed of a Zumo chassis loaded to a weight of 500 g (i.e. the maximum allowed for Mini Sumo) and driven with these motors. Note that the specifications are for 6V operation, which is approximately the voltage you would get with four alkaline batteries; four NiMH AA cells will typically provide less than 5V. | Micro Metal Gearmotor | Free-Run Speed @ 6V | Stall Torque @ 6V | Stall Current @ 6V | Top Zumo Speed @ 6V and 500g | |---|---|---|---|---| | [50:1 HP](https://core-electronics.com.au/50-1-micro-metal-gearmotor-hp-with-extended-motor-shaft.html) or [50:1 HPCB](https://core-electronics.com.au/50-1-micro-metal-gearmotor-hpcb-6v-with-extended-motor-shaft.html) | 625 RPM | 15 oz·in | 1600 mA | 40 in/s | (100 cm/s) | | [75:1 HP](https://core-electronics.com.au/75-1-micro-metal-gearmotor-hp-with-extended-motor-shaft.html) or [75:1 HPCB](https://core-electronics.com.au/pololu-75-1-micro-metal-gearmotor-hpcb-6v-with-extended-motor-shaft.html) | 400 RPM | 22 oz·in | 1600 mA | 25 in/s | (65 cm/s) | | [100:1 HP](https://core-electronics.com.au/100-1-micro-metal-gearmotor-hp-with-extended-motor-shaft.html) or [100:1 HPCB](https://core-electronics.com.au/100-1-micro-metal-gearmotor-hpcb-6v-with-extended-motor-shaft.html) | 320 RPM | 30 oz·in | 1600 mA | 20 in/s | (50 cm/s) | | [![](https://core-electronics.com.au/attachments/localcontent/0J9837_10600e8cac4.jpg)](https://core-electronics.com.au/attachments/localcontent/0J9837_18993614c35.jpg) | |---| **Batteries (not included)** The Zumo robot runs off of four AA batteries.
