Pololu Zumobot Overview

We’ve had several people ask us about our favorite sumobot by the folks at Pololu.  Although they sell models that are fully assembled we prefer to build ours from their kit.  Here’s an overview of what we use. What is a Zumobot: Pololu makes kit, called Zumobot, that combines an Arduino shield with a small…read more

The zumobot we call stickers, seen below on the left, used to have a little OLED display on it. However that got re-purposed for another project. So it’s been driving around with four wires hanging out the back. After the latest upgrade the wires are now connected to a 0.96″ 128×64 monochorme OLED.  The display from…read more

RC controlled WALL-E zumobot

This is a combination of two 3D projects from thingiverse to create a WALL-E skin for Pololu’s zumobot.   The RCControl code from Pololu worked without any code modification.  The servo for WALL-E head is connected directly to the RC receiver so no code is required.  The SR04 sensor is not hooked up but just…read more

RC controlling robot arm and Arduino Uno

Connecting a RC controller to a robot arm can make controlling it easy and fun.   For this project I used a Ironnik KA-6 transmitter and receiver combo.  There are other combos that are significantly less expense, but this is a nice quality unit that was available at my local hobby shop. https://www.hobbytown.com/ka6-6channel-transmitter-receiver-hitec-red-mode-2-by-ikonnik-knna1000/p501569 This is a…read more

SumoBot Clinic

We ran a small SumoBot clinic for some elementary kids.  In Silicon Valley style it was out of our garage.  In the course of two hours they assembled their robots, which included some soldering.  The pizza and other fun distractions limited the amount of hands on programming time.  We did get all the Arduino software…read more
