The two-layer Circular Robotics Chassis Kit is a sturdy, miniature robotics kit designed for beginners and experienced roboticists alike. The chassis plates are made from two 1.5mm aluminum alloy frames milled with plenty of mounting points for sensors, servos, controllers, power and more. Assembly is simple; with just a few included screws needed for construction, you will have a reliable 2WD robotics chassis.
The Circular Robotics Chassis Kit does not include any motors or motor controllers, allowing you to choose your own. The kit, however, does include wheels, frames, a ball caster and all assembly materials like screws, bolts and standoffs. In our opinion, this is one of the most durable and economical chassis we have used in quite some time, and it works amazingly well with a [Raspberry Pi](https://www.sparkfun.com/categories/233), the [SparkFun moto:bit](https://www.sparkfun.com/products/14213) or our [Wireless Motor Driver Shield](https://www.sparkfun.com/products/14285).
**Note:** The Circular Robotics Chassis Kit does **NOT** include [motors](https://www.sparkfun.com/products/13302), a motor controller or a power source. These items will need to be purchased separately. Assembly is required.
