Laser-actuated Multi-fingered Hand for Dexterous Manipulation of Micro-objects

Dexterous robotic manipulation refers to the coordination of multiple fingers or manipulators grasp and manipulate a target object. In past decades, various achievements have been established in dexterous physical world. However, such ability is rarely found nano/micro manipulation, which mainly due difficulty developing actuators sensors at nano/micro-scale, as well dependence on properties objects. As result, only limited relatively simple micro-manipulation tasks pushing picking realized so far. Here, we demonstrate platform achieve micro-world by micro multi-fingered hand that actuated optical traps. The system consists several laser-actuated are coordinated function micro-hand. Each micro-finger configured with three degrees freedom 2-dimensional space, composed micro-fingers can then be utilized for grasping, rotating, moving, even levering rolling objects micron scale. Thus, proposed approach this paper establishes foundation achieving scale through fingers.
