WebA canonical example of a kinematic coupling consists of three radial v-grooves in one part that mate with three hemispheres in another part. Each hemisphere has two contact points for a total of six contact points, enough to constrain all six of the part's degrees of freedom. Webthe coupling is not overconstrained, an extensive wear-in period should not be required. If the theory could be proven, then kinematic couplings could be easily designed for various precision fixturing applications in a production environment. For example, if …

Kinematic constraints are constraints on the movement of components of a mechanical system. Kinematic constraints can be considered to have two basic forms, (i) constraints that arise from hinges, sliders and cam joints that define the construction of the system, called holonomic constraints, and (ii) constraints imposed on the velocity of the system such as the knife-edge constraint of ic… WebA typical example is shown in Figure 1, where a kinematic coupling constraint is used to prescribe a twisting motion to a model without constraining radial motions.

Webcoupling. In 1973, Hunt cataloged a variety of couplings, including this R-R-S-R-R coupling. Although these devices have an architecture similar to that of the proposed wrist, they differ substantially in application. For example, all of these earlier works treat the device as a passive torque coupling rather than as an actuated positioning device.

WebKinematics is the description of motion. The kinematics of rotational motion describes the relationships among rotation angle, angular velocity, angular acceleration, and time. Let us start by finding an equation relating ω, α, and t.To determine this equation, we recall a familiar kinematic equation for translational, or straight-line, motion:
