Here’s the first robot I started with. It’s the GoPiGo3 by Dexter Industries, and it’s the most expensive one on this list at around $100. The reason it’s so pricey is because it’s more than just a chassis, it’s a system that comes with it’s own motor and sensor board that plugs right in to a Raspberry Pi computer board that you need to supply and will also set you back another $35.
