  While parallel grippers and multi-fingered robotic hands are well developed
and commonly used in structured settings, it remains a challenge in robotics to
design a highly articulated robotic hand that can be comparable to human hands
to handle various daily manipulation and grasping tasks. Dexterity usually
requires more actuators but also leads to a more sophisticated mechanism design
and is more expensive to fabricate and maintain. Soft materials are able to
provide compliance and safety when interacting with the physical world but are
hard to model. This work presents a hybrid bio-inspired robotic hand that
combines soft matters and rigid elements. Sensing is integrated into the rigid
bodies resulting in a simple way for pose estimation with high sensitivity. The
proposed hand is in a modular structure allowing for rapid fabrication and
programming. The fabrication process is carefully designed so that a full hand
can be made with low-cost materials and assembled in an efficient manner. We
demonstrate the dexterity of the hand by successfully performing human grasp
types.
