BUILD REPORT Battle Hardening the Inside of Your Bot
With robot combat, often the first things you’ll think about are the big parts — typically, the armor, weapon, and drive system.
Skill Building — Drive Better
Robot combat is a sport with extreme design diversity. You’ll see spinners, flippers, axes, crushers, pushers, and a range of other things constantly pushing the limits of what’s safe and what’s legal to run at an event.
PRODUCT REVIEW: FingerTech Robotics’ Viper Kit with Lifter Add-on
FingerTech Robotics has offered a "Viper" robot kit for quite a few years, but for a long time it was not really a great starter combat bot if you wanted something that would be competitive. It worked well enough, but without some extensive modifications it was difficult to turn it into a competitive combat robot.

BUILDER’S TIPS: You Can’t Take It With You: What Tools To Bring
I won't be talking about tools that are particularly specialized. If your machine needs any specific equipment for basic maintenance and repairs, those take priority. The following sections will cover tools that are almost universally useful in the pits during an event.

Kobalos is a miniaturization of my 12 lb robot, Apollyon. The basic idea was to build something that would be as close to indestructible as possible.
BUILD REPORT: Apollyon 2
Concept to Creation.
Life Cycle of a Fighting Robot
Apollyon started as a concept for a simple but somewhat unique 12 lb wedge bot. The original design started as a sketch in a notebook during class. Later, it moved into 3D in the CAD program Rhinoceros.
Combat Robot Drive Systems
There are many ways to move your robot around the arena floor. From the simplistic two wheel drive robot to the precision crafted complexity of a true walking robot, there are always different methods of movement to consider.
Even More Things to Consider When Building a Fighting Robot
In previous issues of SERVO, I’ve talked about weapon and drive systems in robot combat. There are a lot of important things to consider that don’t fit under either of those umbrellas but still merit consideration when building your bot.
Mr. Self Destruct
Mr. Self Destruct is a complete overhaul of my first large combat robot: a 60 lb angled bar spinner that fought at RoboGames in 2006.
