WebApr 15, 2024 · The form closure is a static state type where any possible motion cannot be produced on a body due to the applied constraints. A form-closure grasp refers to such a state where the constraints are provided by robot fingers. The form closure grasp is formulated as follows: Let WebTwo primary restraint properties are form closure and force closure. A form closure grasp guarantees maintenance of contact as long as the links of the hand and the object are well approximated as rigid and as long as the joint actuators are sufficiently strong.
