Scientists at the Wyss Institute at Harvard University have developed miniature robots and the surgeon milliDelta using the technique of origami. In expanded form it corresponds to odnolistovoe coin (19 mm diameter).
But even with such modest dimensions it is equipped with flexible connectors, bends, piezoelectric actuators that give it, unlike its predecessors unique mobility, precision and the necessary speed of movements. Mini robot operates at a frequency of 75 Hz. According to its creators, the robot can perform several microsurgical procedures in a confined space.
When creating a mini-robot, the researchers used the technology of Pop-up MEMS, making it possible to create complex structures out of flat materials. This approach has already been used when creating the RoboBee flying robot.
In the final step, the researchers intend to modify the specifications of a robot surgeon to determine its final design and to improve the management system.
