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

These rule sets will dictate the types of machines you can build and how to make them safe.
Also make sure that you check the rules for the competition you are thinking about. I try and keep two things in my mind at all times: 1 Is this robot unique from others? Does it have that wow factor, and will I be happy with it as a personal product as well as how competitive it might be 2 How easy will it be to maintain.ĭoes changing a fried motor require the complete dis-assembly of the robot? Can I change parts out in mins if needed? Those two key concepts help focus your thoughts when thinking about your bot. It is one of my personal rules that when I start thinking about a design I look for robots that have done similar things and try to see what was successful and what wasn't so I can always improve on the design concept. Also the more layout is done before the final design the easier to transition to computer design for machining. I always do a few concepts and some initial layouts so that I can make a determination as to the best design. Also having at least 2 sets of batteries will be necessary for competition. The last thing anyone wants is to get part of the way into the build and then not be able to finish due to funds. Robotics is a fun hobby and can fit any budget if you plan for it. The main reason that setting a budget is important for your project is that you can very easily spend hundreds if not thousands of dollars very quickly. Below is a list of the components commonly required for most combat robots. Anther good starting point is to determine how much money you are willing to invest. Because of this you can easily browse hundreds of other robots in your weight class. When I start the project I always take a look at what people have done already and draw from the knowledge learned by others over time.Ī good place to start with your research is the builders database. The first step to building a bot is to think about what kind you would want to build. This Instructable will walk you through the steps and provide you with resources to help with the machine and give an understanding of what is involved using my 30lb robot as an example.ĭid you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Regardless of the size of the machine the steps in the process are the same. This is a simple, quick-build design that has been used by classroom teachers around the world.Combat robots have been entertaining and amusing since before they were popular on Comedy Central.Ī while back I undertook the challenge of building a couple of combat robots a 30lb and a lb. They may require parts beyond the retail or educational kits. We name it Cyberbot because of its distinctive handle which makes it look like a Cyberman from Dr. It has been designed for use in our lessons and also works well on our Training Mats. This new NXT robot design is compact and very sturdy - ideal for classroom usage. The Cyberbot recommended NXT build for our lessons. Note: You will need a second color sensor to do the Squaring lesson. It has been designed to allow the builder to easily replace the infrared sensor with the ultrasonic, use a rechargeable battery, and add a gyro sensor if needed.
An optional handle allows for easy carrying in classrooms. This build is slightly smaller than Droid Bot 2. There is also an optional handle that can be added when the robots are used in camps or classrooms. The robot has optional instructions for adding a second color sensor. This robot has been tested and approved by EV3Lessons. The infrared can also replaced with the ultrasonic if needed. The robot has optional instructions for adding a gyro and second color sensor. Sensor and motor modules easily snap on to the base robot as the student needs. This robot has a base that only uses 82 pieces. EV3 Enterprise Recommended build for our lessons.
