<p>If you want to do anything significant with robotics, a simple kit will cost you at least $100. I have a Vex kit, (I got it on sale for $150 when they used to be at Radio Shack, and that’s the best price you’ll find) and it’s a great platform for any type of competition. There are many basic and complex types of bots that you can build in a relatively short period of time. I strongly recommend Vex if you can afford it.</p>
<p>Also, robotmarketplace.com and trossenrobotics.com have lots of individual parts if you’re really looking to build something.</p>
