Fabricated vessel-mimetic microtubes are essential for delivering sufficient nutrient to engineered composite tissues. In this paper, vascular-like microtubes are engineered by automated assembly of donut-shaped micromodules that embed fibroblast cells. A microrobotic system is set up with dual manipulators of 30-nm positioning resolution under an optical microscope. The system assembles the micromodules...
3D assembly of cellular structures is important for the fabrication of biological substitute in tissue engineering. In this paper, a novel rail-guided multi-microrobotic system was proposed for the assembly of cellular structure. The cellular 2-dimensional (2D) module was fabricated by UV illumination of the crosslinkable hydrogel. The coordinated manipulation among the micromanipulators was performed...
A novel rail-guided dextrous stick coordination manipulation (DeSCom) system was proposed for the assembly of cell-laden three-dimensional (3D) constructs. The coordination control between three dextrous sticks was realized based on the vision feedback and the manipulation resolution was around 30 nm. It was set up with hybrid motors to ensure the large operation range and operation precision. The...
