Although an Arduino can be a great way to provide computing power for a mobile robot platform, you’ll need a variety of other electronics and mechanical components to get it going. In his write-up, computer science student Niels Post outlines how he constructed a robot that travels via two stepper motors, along with casters to keep it upright. The round chassis is 3D-printed and runs on three rechargeable 18650 batteries.

The platform is based on an Arduino Due, with stepper drivers and a custom PCB to take care of the wiring. The robot has no sensors or navigation aids onboard, but instead relies on an nRF24L01+ module to communicate with a Raspberry Pi that hosts the web interface for control and livestream viewing. This setup employs a webcam to sense and direct the robot through its environment using printed markers.
More details on Post’s project can be found in his Instructables tutorial.
