Kinematics of beam flexure four-bar linkages with applications in a compound bow
… important aspects. First, one grounded link of a four-bar linkage is replaced by a cantilevered beam in flexure to produce a force generating mechanism. Second, the synthesis method presented here allows the generation of these mechanisms in closed form for prescribed force generation. A compound …

Bipedal Walking for a Full Size Humanoid Robot Utilizing Sinusoidal Feet Trajectories and Its Energy Consumption
… CHARLI-L utilizes spring assisted parallel four-bar linkages with synchronized actuation to achieve the goals of lightweight and low cost. Based on the experience and lesions learned from CHARLI-L, CHARLI-2 uses gear train reduction mechanisms, instead of parallel four-bar linkages, to …

Synthesis of planar four-link mechanisms for force generation
… presents a technique for synthesizing weighted four-bar linkages to produce a specified resisting force or torque. Historically, mechanism force synthesis has assumed that output positions must always be associated with prescribed forces. This results in the loss of design parameters. …

Optimal synthesis of force-generating planar four-link mechanisms
… a technique for the optimal synthesis of planar four-bar linkages for specified force or torque generation. Unlike most previous research in mechanism force synthesis, this thesis targets linkage applications for which the mechanical advantage is prescribed but the position function is not. The …

Optimized Sythesis of a Force Generating Planar Four-Bar Mechanism Including Dynamic Effects
… thesis presents a technique for designing planar four-bar linkages by coupling optimization, dynamics and kinematics. This synthesis technique gives the designer the ability to design linkages having a desired resistance profiles under an assumed motion profile. The design approach presented in …

Optimal synthesis of planar adjustable mechanisms
… without directly comparing them; and its compact fourth-order polynomial form facilitates the gradient- based optimization process. Link length structural error based optimal synthesis methods are developed for adjustable planar four-bar mechanisms for three typical synthesis tasks. For …
