Beyond.

Phase 4 is the end of the planned build. Beyond it, two directions extend what Chappie is.

The first is legs. The wheeled base is limited to flat ground. Stairs, thresholds, and uneven terrain all need legs. The next form of Chappie has them, trained to walk.

The second is moving the brain fully on-device. Right now the AI stack calls out to cloud APIs for language and vision. A hardware upgrade brings those models onto the Jetson, removing the latency, the cost per call, and the connectivity assumption. Chappie stops needing the internet.
