Human hand is the most complex and highly dexterous organ in the body. It allows humans to accomplish movements and perform task with power and precision. Developing a bionic hand requires understanding of human hand physiology and its motion. Much research has been taken place in this field and few companies made it commercially available, but present day bionic hand have few limitations and are not suitable for Indian context. This thesis work attempts to design and develop an effective bionic hand while performing its kinematic simulations. Based on the Indian human anthropometry a conceptual design is developed, bionic hand is used for grasping and manipulation. Grasping forces are computed using force formulas. Kinematics of the hand are evaluated through D-H algorithms using ADAMS. Based on the forces calculated for various gripping actions, selection of motors for actual hardware development for the bionic hand. CAD model developed for the hand using SOLIDWORKS was eventually used for 3D printing. The 3D printed model was wired with all the procured motors and electronic hardware to make it as a working prototype. The built prototype was tested for various haptic actions and gripping actions. The prototype worked as expected performing the desired actions. It however has to be tested for the gripping forces and for varying payloads as a future work. The developed Bionic hand is suitable for Indian context and affordable
