Ultimate fights and battles are waiting for you in the best robot fighting games. Flash Games. Super Crime Steel War Hero. Those two key concepts help focus your thoughts when thinking about your bot. Also make sure that you check the rules for the competition you are thinking about. These rule sets will dictate the types of machines you can build and how to make them safe.

The last part of the initial design is to figure out what parts you have that might work and do a quick layout of your basic overall dimensions, with weight limits for each subsystem.

The more planning you do at this stage will help along the way. Every bot is made up of a combination of both manufactured and purchased components. Choosing the right components is crucial for a successful robot.

In this step I will step through some of the major components for small to medium robots and how you choose which is right for your bot. Motors: The driving force behind any size robot you build. They make your robot move and in many cases power your weapons. The motors used in combat robots are DC or Direct current motors, designed for anywhere between 3 and 72 volts.

Just like every other component you need to make decisions to choose the right one. Motor torque is typically rated in oz-in or in-lbs at the "stall" area.

Since dc motors produce their maximum torque with minimal RPM stall torque is only a reference point. I only use the torque as a baseline for comparison for different motors and try to get the most torque I can within my other constraints.

Size and weight go hand and hand since the larger form factor your robot is the more it will weigh. When defining the size of your bot try to make it as small as possible without sacrificing functionality. Voltage is one of those things that is my last priority, most motors are 12 volts but for those that aren't you just need to make sure that your electronics all match the voltage of your motors.

Common motors used for lb robots: Drill motors - cheap drills from discount tool store harbor freight are stripped from their housings and mounted for the drives. Many people also use the battery packs from these drills as well. While the cheap drills are common many people spend the extra dollars for high quality ones such as ones made by DeWALT.

Banebots - banebots is a company founded a few years ago for the sole purpose of providing parts for combat. They have a large range of motors and transmissions which are "ready to run" out of the box.

For the convenience of not having to modify drills to get the motors I chose these for my robot, the old 36mm series which I used broke easily, but I have had good results with the new 42mm ones. The saying don't reinvent the wheel comes to mind for this section as there are as many different styles of wheels as there are builders in this sport.

The main question you need to ask yourself is if you want a live axle or dead axle system. In live axle system the wheel is hard mounted to the axle similar to a wheel in a car. The challenge with this system is that now you will need to have bearings on the shaft and find a way to couple the wheel to the axle.

In a dead axle setup the wheel freely spins on a shaft and is usually driven by a sprocket or belt attached directly to the wheel.

While this system may seem easier it still has it's own challenges like the need for a power transmission method chain or belt and in the small spaces for this size robot direct drive systems work better. The most common wheel used for most all combat robots is made by the colson company and is a soft urethane wheel which performs well on the many different arena surfaces. The major problem with these wheels is that they don't have a way to drive them for live axle applications.

For my robot I made custom hubs on a lathe but you can buy pre-made colsons' with hubs from places like Banebots Banebots recently came out with some of their own wheels similar to colsons' but I have not seen or tested them. Building Materials - Small robots use a variety of materials from composites like carbon fiber sheets and aluminum.

Just like any other component on your machine each material will have advantages and disadvantages. These are a few of the ones used commonly. Aluminum: is a light weight common metal which can be easily formed and machined.

It is used for the chassis of most machines for those reasons. Aluminum comes in many different alloys but the most popular ones are T6 which is heat treated and suited for machining and welding. This alloy can be soft and not great for impact resistance so use it for components which arn't going to see direct contact. UHMW - is a durable plastic commonly used for internal components as mounts.

It has a bit of give to it, but it holds up well under competition. It is also very easy to form with even hand tools. Polycarbonate - or lexan as it is commonly known is a clear durable plastic which is for the most part impact resistant and light weight. Under extreme impacts it can crack and break away so use it for top panels but not armor. Titanium - a great material for armor but it is very cost prohibitive, although many builders still use this for high end machines. For my robot I used both and aluminum.

Mainly for my supports and chassis and for my outer frame supports. CAD is the system used by all professionals for the creation of the products you see and use everyday. It allows you to make 3D computer renderings, seeing how things fit together on the computer before you build.

This step can revel potential problems on your bot which will reduce your time and cost overall. It is a common thought that CAD systems are difficult to use and build if you are not an engineer or have been trained to use them through some class. Recent CAD software has been shifted from even five years ago so that they are easier to build models with a user interface that anyone can pick up and learn within a few hours.

Within industry the three most popular pieces of software are Autodesk Inventor, Solidworks, and Pro-e. Each one of these has advantages and disadvantages to their own right but all are comparable for this type of design. I will not be going into how to use CAD in this instructable but there are many resources online for using this type of software.

Buying CAD software can be very expensive but fortunately there are many opportunities for free licenses of software if you are a student, or if your company has licenses of the software.

They also have a great tutorial for robotics design located here. Stock parts like bearings, screws, motors, etc can be found. Using these models will save time when modeling.

The most important thing about CAD design is that you have your dimensions right. Now that may seem like a straight forward piece of advise but I see loads of people trying to make realistic renderings and spend too much time making their parts look nice instead of focusing on the real goal of CAD to make models which are accurate.

I am going to leave this step because if you take the time to learn CAD the process steps for design in the software become more apparent. If you choose to skip this step due to the inablity to run the software or the lack of interest I recommend a "cardboard template" method. Take cardboard and cut out scale models of each one of your parts for layout, before you cut your real material.

For exact machining you are dealing with thousands of an inch. Depending on how much design and your resources you can start building parts. There are many ways to do things, hand tools jigsaw, hammer, etc , Manual mill lathe, full cnc; Which ever method you choose Make sure you are Safe.

If you are building a budget robot you will most likely be using hand tools or light power tools. This is the method used by more bots than anything else. The only advise that I can offer for doing this is to take your time and use the templates or CAD drawings you created to help in the process. One of my preferred methods for this when I am unable to use the machine shop is to make drawings from CAD in a full scale and paste them to the material then use those guides to cut your parts.

The next step up from manual tools is a standard machine shop. If you have access to a Mil or a lathe you will be able to create highly accurate parts. These tools can be very dangerous if you don't know what you are doing so make sure supervision or proper instruction happens before you start.

If you are looking for access to a machine shops most towns and citys have them and you should be able to open a phone book and find someone to help. Sometimes they are willing to donate their time other times you will need to pay for their time. At this day in age there are some great resources online for manufacturing which can help you out.
