MoleBot

This research introduces MoleBot, a robotic system integrated into a coffee table designed to interact with physical objects on the surface by projecting a moving molehill. To facilitate fluid movement, the project developed a unique tabletop architecture that balances structural rigidity with vertical flexibility. While prior organic user interfaces and shape displays utilized servo motors, shape memory alloys, and pneumatic actuators, these methods were found insufficient for achieving the specific actuation speed, resolution, and pixel size required for high-fidelity physical interactivity. Consequently, this study explores a novel implementation method that allows the subterranean robotic entity to manipulate surface items in real-time. By bridging the gap between digital control and physical kinetic motion, the system provides a compelling platform for investigating tactile interactions and tabletop-based entertainment
