How to Design and Build a Combat Robot 1. Steps with PicturesEvery 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 7. Just like every other component you need to make decisions to choose the right one. The four traits to consider in on each motor is torquespeed, voltage, size, and weight. 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. Hp Deskjet Ink Advantage 2060 Driver Download. 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 1. Common motors used for 1. 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 De. WALT. 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 3. Drowning In Plastic The Great Pacific Garbage Patch more.

Other motors A wide assortment of motors exists you can check out many of them at the robot marketplace. Wheels The wheels on the robot go round and round. The saying dont 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 its 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 dont have a way to drive them for live axle applications. Biggest list of free hacking tools for you to hack proficiently. Bitcoin.

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 6. 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 arnt 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 6. Mainly 6. 06. 1 for my supports and chassis and 7. I used a live axle setup with banebot 1. Search the worlds information, including webpages, images, videos and more.
