YetiBorg v2 is a great kit to get started with Raspberry Pi robotics.
The YetiBorg v2 kit can be assembled into two different configurations so you can customize the robot to do what you want it to.
If you are looking to build a speedy racer then the low profile build is for you. The low profile build is the most compact and has the ability to flip over and drive upside-down, just like the original YetiBorg it is based on. The camera is positioned low to the floor to improve autonomous driving and the Pi Zero is safely housed in the center of the robot.
If you want to drive on rough ground then you want the off-road build. This version has much higher ground clearance and keeps the electronics up high away from any mud and puddles. The camera is also positioned higher so you can see over rocks and lumps.
