Get some inspiration from this robot build that was created by using a lot of common items in a unique way.

Basics of Soldering

Roboticists need all kinds of different skills to construct their automatons. Knowing how to solder is invaluable in this process.

The Schmitt Trigger and How It Works

Whether because of harsh environments or the inherent limitations of sensor technology, output signals are rarely as clean as we'd like. Sensor noise can overwhelm a navigation system or even a simple robotics control system. You can take steps such as adding shielding to cables (adds weight), defining noise gates in software (takes space and degrades overall computational performance), and investing in better, more expensive sensors.

MF70 Micro Mill CNC Conversion

Combat Zone

BUILD REPORT: The Weta Equation

Weta, god of ugly things — my 3 lb Beetle weight — has always had a different beater bar than the kit bots for which it was the prototype.

EVENT REPORT: Pennbots Downtown Dogfight 2014

Back in March of this year, 22 robots gathered at Harrisburg University in Harrisburg, PA to participate in Pennbots' annual Downtown Dogfight competition.

EVENT REPORT: Clash of the Bots 2014

Clash of the Bots 2014 took place in Gastonia, NC at the Schiele Museum on July 19th. This was the fifth Clash of the Bots event and the eighth overall event put on by Carolina Combat Robots.

BUILD REPORT: Nyx v2 Part 2: Platform

With the design portion of the build completed, the next big step in the build is to fabricate the major structural components and build the drive platform.

BUILD REPORT: Using Actobotics in Combat Robots

Recently, I had the opportunity to try out some of the new Actobotics products from


I have employed pretty much the same design for three pound robots since around 2002.


Three weight classes, 35 robots, and one 10x10 arena took center stage at Bot Blast 2014 at the Columbia Mall in Bloomsburg, PA on Saturday, July 13.

BUILD REPORT: Nyx v2 Part 1: Design

Nyx was originally built in early 2012 and first competed at Motorama in February of that same year.

When Micah from Team Tiki fame was searching for someone going to an upcoming event to test out his new gearmotors, I knew I had the perfect storm.

BUILD REPORT: Isotelus Rex — Part 3

In Parts 1 and 2 of this series, I showed how I designed my new 12 lb combat robot, and then revised the design so that it would meet the weight restrictions.

BUILD REPORT: Spanky Part 1: A Combat Robot Platform

Spanky is the newest robotic member of Near Chaos Robotics. Spanky was designed with two events in mind: DragonCon Robot Battles — an open platform Sumo style event; and the Sportsman class at Motorama — an event with a full arena.

BUILD REPORT: Spanky Part 2: Modular Weapon Systems

With the drive platform done and almost eight pounds to spare, there was a lot of room for the weapon systems.

EVENT REPORT: I was a Team’s Toadie

The event was streamed live at (You can go back and watch all the fights, as well as all the in-between stuff.)


Afew months ago, I was making a batch of drums for my Saifu Ant kits when I received an order for a wider drum for a customer who was building his own chassis.

My first attempt at a Fairyweight combat robot had been a failure when I built it to meet an imaginary 250 g weight limit, rather than the actual 150 g limit.

BUILD REPORT: Isotelus Rex — Part 1

Aweight class in combat robotics can be dominated — often for years — by one particular bot.

BUILD REPORT: Dolos: A Trip into the Used Bot Lot

Dolos began its existence in 2008 under the name Test Bot 4.5 SP1, and was originally built by Charles Guan.

EVENT REPORT: Putting on the Bots

For me, DragonCon is not a huge science fiction convention filled with panels, viewings, exhibits, parades, games, and elaborate cosplay that combine to contribute an enormous burden to the already crowded streets of Labor Day Atlanta and an equally weighty contribution to the bank accounts of the five main participating hotels.

Pushing Power: How Strong is Strong Enough?

This month, we address the other variable: torque. In terms of robot combat, torque is our fancy word for pushing power.

The Evolution of Attitude

My venture into the three pound Beetleweight class began in 2009 when I was in the eighth grade.

Don’t Bite Off More Than You Can Chew Part 2: Designing an Asymmetric Weapon

Last month, we discussed the design and performance compromises that accompany the use of an asymmetric weapon. If you decide that this design is right for your robot, the next step is to start concocting your weapon.

EVENT REPORT: The Adventures of Scary and Angry Bot

Last month, I did a brief report about how my two sons and I built their first "real" combat robots — "Angry Bot" and "Scary." This month, I want to discuss how they did in their matches. You may be a bit surprised by the result.

Old School Lathes

This is not your typical product review. I’m not going to tell you about a brand new product, a cutting edge piece of technology, or a product that will revolutionize the way we all work. I’m not even reviewing a single product. Instead, I am going to look at the subject of old lathes and why you should buy one.

BUILD REPORT: New Builders, Beware!

Here are some tips to avoid some common pitfalls at your first competition.

BUILD REPORT: Isotelus Rex — Part 4: The Sprint to the Finish Line

In Part 3 of this series, I had received most of the parts and started work on the chassis. Is this part, I will put together the drive motors, complete the rest of the parts, and assemble the bot. I was on a tight deadline as there was only four weeks to go before the bot’s first event ...

EVENT REPORT: DragonCon Robot Battles 2014

On Monday, the 12 and 30 pound machines competed in a Sumo style competition for Robot Battles 50.

2014 STEM Tech Olympiad

We are thrilled to announce the 2014 STEM Tech Olympiad! The event will take place at the Miami Beach Convention Center in South Florida on May 4-6.


Pololu produces an interesting set of components that allow you to have caterpillar type tracks on your small 250 g to 1 lb combat bots.


It’s probably a sign someone has been doing this too long when — upon sifting through ye olde junk box and coming across two needle bearings, a shaft, a piece of mild steel, and a brushless motor — the only thing that comes to mind is combining the steel with the shaft, inserting it into the bearings, hooking up the brushless, and wondering what’s got the cat so worked up.


The 1.5" and 2" wide Colson wheels have been popular in the 30 lb+ weight classes in combat robotics for many years, but builders often had to make their own hubs to mate the large bore of the Colsons with the standard 1/2" keyed shafts that come on drive gearmotors like Banebots P60s.

EVENT REPORT: Franklin 2013 — Fall Fun in Philly

The Franklin Institute in Philadelphia ( hosted its 7th annual robotic combat event on September 21, 2013. The Institute provides the venue arena and N.E.R.C. ( organizes the event.

PRODUCT REVIEW: FingerTech Robotics TinyESC v2.4

TinyESC speed controllers have typically been the ESC (electronic speed controller) of choice for the drives of many Ant and Beetleweight combat robots.

EVENT REPORT: Thunderdome

Thunderdome is a new event to South Florida aiming to give builders a venue to compete multiple times a year. Spectators can learn from competitors and come back with a robot of their own.

Buzz Dawson: Rockets to Robots

In September, the world of combat robotics lost a founding member, Brett "Buzz" Dawson. Buzz was an integral part of the creation of our sport, as well as one of our media rock stars. The SERVO family is greatly saddened by his loss, and wanted to share some of our favorite stories.

BUILD REPORT: Printing Cheese

The 3D printing phenomenon had more or less passed me by. I had learned to use one at the TechShop in Raleigh, NC, but that wonderful resource closed days after my course and I never got a chance to use their machines.

THEN AND NOW: A Decade Later with Alexander Rose

This is the next installment in our series of articles about famous figures from a decade ago. 2002 ended the popular Comedy Central series, BattleBots™.


The Problem With Too Much Experience
by Bryan Bergeron
It's good to question the beliefs and experience of others and, at times, experiment with things first-hand. If you want to be an innovator, you've got to be a risk taker.
