LVBots held a mini-sumo competition at Pololu on September 19. With a total of 19 robots participating, we got to see a lot of different strategies, from passive to aggressive to deliberately misleading. Sensing technology was of key importance, with robots using everything from sonar and optical rangefinders to accelerometers. See the range of designs for yourself in this video compilation from the contest:
Do you live in Las Vegas, or are you passing through? Stop by this evening to see the robots in person! You can find out more about LVBots or sign up on our Meetup page.

We now carry the Arduino Robot, the first official Arduino on wheels, which includes a pair of ATmega32U4-based platforms that control two motors, sensors, and more. From the Arduino blog post about it:
Designed in cooperation with Complubot, 4-time world champions in the Robocup Junior robotics soccer, the Arduino Robot promises endless hours of experimentation and play. It is a self-contained platform that allows you to build interactive machines to explore the world around you.
You can use straight out of the box, modify its software, or add your own hardware on top of it. You can learn as you go: the Arduino Robot is perfect for both the novice as well as those looking for their next challenge.
For more information about the Arduino Robot, see the product page.
We are now carrying the V4 revision of the RoboClaw 2×60A motor controller from Orion Robotics. This new revision is similar to the original 2×60A version but has a new board design and some new features like USB connectivity. We expect to have an updated datasheet soon.

Arduino Yún is the combination of a classic Arduino Leonardo (based on the Atmega32U4 processor) with a Wifi system-on-a-chip running Linino (a MIPS GNU/Linux based on OpenWRT). It’s based on the ATMega32u4 microcontroller and on the Atheros AR9331, a system on a chip running Linino, a customized version of OpenWRT, the most used Linux distribution for embedded devices.
Like a Leonardo, it has 14 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator and a micro USB connector.
Like any modern computer, it’s Wi-Fi enabled, it has a Standard-A type USB connector to which you can connect your USB devices and it has a micro-SD card plug, for additional storage.
For more information about the Arduino Yún, see the product page.
We have expanded our selection of NEMA 23-size stepper motors:
The SparkFun Inventor’s Kit has everything you need to construct a variety of circuits that will teach you how to use an Arduino-compatible RedBoard to read sensors, display information on an LCD, drive motors, and more. No previous programming or electronics experience is necessary, which makes this a great way for beginners to get started with embedded systems. The V3 version includes a RedBoard and detailed instructions for building 15 educational circuits with the kit components.
This replaces the older SparkFun Inventor’s Kit for Arduino with Retail Case.
For more information about the SparkFun Inventor’s Kit, see the product page.
In this video, Brian Patton demonstrates how to program an animatronic robot using a Maestro Servo Controller. He covers basic configuration using the Maestro Control Center and shows how to sync voice with servo motion using software from his company Robodyssey.

Pololu Forum user VolAnd, writing from St. Petersburg, Russia, posted about an app that turns a Wixel into a USB SD card reader. The Wixel identifies itself as a mass storage device, and basic read/write operations are working. His goal is to create files with the Wixel that he can then read from a PC. You can read more or get the app from his forum post.
This Wixel app and many others are available in our listing of community-contributed apps on the forum.
