Difficulty: Moderately Easy
Step1
Look carefully at your robot specs. The drive train is the most important part of the robot, as this is what allows the robot to move.
Step2
Take your specs to a local hobby store that specializes in robotics. If you don't have a local hobby store, search the Internet for companies that sell robot parts online.
Step3
Compare prices online and from the hobby store. Working with a local expert is one of the best ways not only to buy parts, but to learn more about robotics as you go.
Step4
Purchase the robot drive train that is best suited for your project.
Step5
Think about buying an entire robot kit with a drive train included. This is a great idea if you are new to robotics and this is your first building project.
Step6
Buy the components necessary to build your own robot drive train. This is fairly easy and what most robotics enthusiasts do after they've had some experience working with robotics.
Step7
Talk to other people involved in robotics or join a robotics club. This will allow you to share information and get the best advice on where to purchase robot parts and accessories.
