AWESOME Robot can be upgraded

Uses the WonderPi app, which is versatile. There are multiple ways to control it, but the app is probably the most accessible for most people. I do have concerns about the long-term support and availability of these apps. They have the option of ordering with or without a Raspberry Pi board. It's very cool. Wheels rotate smoothly, make tight turns. And it's actually faster than you might think. Parts are all good quality. Durable aluminum alloy chassis. It's accessible to a variety of skill levels. There are lots of actions you can perform without needing to code. Stacking functions gives you infinite possibility. For example, color tracking, facial recognition, object tracking, object sorting... and all of those commands can be stacked. Assembly is pretty straightforward.
