01 // ISOMETRIC 3D CAD RENDER
01 // TECHNICAL CHALLENGE
Legacy grippers caused micro-fractures in fragile semiconductor wafers during pick-and-place at acceleration forces > 3G.
02 // ENGINEERING & DFM SOLUTION
Integrated a four-bar linkage compliance mechanism with soft silicone vacuum pads and real-time closed-loop force sensing feedback.
03 // MODELING & TOLERANCING HIGHLIGHTS
—Four-bar linkage kinematic trajectory optimization
—Integrated pneumatic channel manifolds embedded in carbon fiber arms
—Finite element strain gage location optimization
