Looking for a fun weekend project? The Sumobot junior is a fun open source robot kit using Arduino and JavaScript. If you already own an Arduino, this kit can be an inexpensive way to tinker with robot building. (i.e. about $50) Since the plans for the chassis are open source, you can customize the robot as you see fit. The design can be completed using a laser cutter or a 3D printer. You might extend the base of the robot so that you can have room for a bread board or anything else you like! You can find complete instructions for building your Sumo Bot JR at http://sumobotkit.com/. The design uses continuous rotation servo’s which are pretty easy to program and re-use in other robot projects. You can purchase the servo’s here: https://www.parallax.com/product/900-00008
While researching this blog post, I found another cool post detailing the process of building a NodeBot Jr.

If you don’t have access to a laser cutter, check out your local makerspace or check out https://www.ponoko.com/. Ponoko.com enables you to upload your laser cutting design and having your designs delivered to your door for a small fee.
