2D Catoms

Realizing high-resolution programmable matter requires millimeter-scale catoms. Within the Claytronics project led by Carnegie Mellon University, researchers have developed and demonstrated millimeter-scale cylindrical catoms that are electrostatically actuated and self contained. As a simplified approach cylindrical catoms were first built instead of spheres. We name here these cylindrical catoms the 2D Catoms. 

Hardware Features

2D Catoms have been partially validated with the realization of a hardware prototype. A 2D Catom consists of a 6-mm long-and 1-mm-diameter cylindrical shell. A high-voltage CMOS die is attached inside the tube. The chip includes a storage capacitor and a simple logic unit. The tube uses electrodes for power transfer, communication and actuation. In the current design, a 2D Catom can roll on a power grid. A 2D Catom is theoretically able to perform a revolution in 1.67 seconds or 3.35 seconds.
