摘要

Use of underactuated fingers to conduct precision, in-hand manipulation is a common topic of recent robotics research, mostly due to their relatively light weight and simplicity of use. Grasping operations are facilitated by compliant joints however precise, in-hand manipulation is more challenging since post-grasp orientation of an object varies. Underactuated, robotic-fingered hands that are capable of predictable grasping are one step closer to human-like end-effectors. This paper presents a new effort towards effective robotic manipulation using two underactuated fingers and one fully actuated robotic thumb with 3 degrees of freedom (DOF). Fuzzy grasping using tactile feedback is used to provide an enhanced stable grasp solution. The system comprises tactile feedback, orientation of underactuated phalanges using flexible joints, and thumb trajectory planning.
