We present the design of a compliant finger based on the topology optimization method through Hill Climber stochastic search. The compliant finger is composed of an arrangement of beams, whose behavior is studied under the formulation of large deformation co-rotational beam elements. The design optimization seeks to maximize deflection of the tip of the compliant finger with the lowest possible input torque and the mechanical advantage via the contact force between the compliant finger and a free-form shaped object. Large tip deformation is sought along a desired path. The actual path traced by the candidate mechanism and the desired path are compared through their Fourier descriptors. Computation of the contact force is performed between the surfaces of Euler-Bernoulli beam and a prescribed free-form shape.
