A Raspberry Pi 2 tank is a great platform to learn about and play around with robotics. But the major disadvantage of these robots is they’re a bit costly. If you want to build one from scratch, we can find great information on the Usefulramblings blog to build one of these projects.
The designer uses a tank chassis platform, LEGO bricks, a Raspberry Pi 2 with Ubuntu Mate OS, Adafruit DC & Stepper Motor Hat, batteries and several other hobby components.
