Plant Fasting Art Display System

Peter Sand has come up with this art display system known as plant fasting, where a huge robot equipped with interchangeable tools to handle a variety of gardening tasks will function seamlessly as a mostly automated system. To make it connect with the current young generation who grows up on a steady diet of video games, the Plant Fasting art display system can be controlled using a game pad, powered by an Arduino behind the scenes. Any ideas on how this can be further improved before it receives mainstream accolades and bouquets?
