By absorbing the advantages of the rotary-driven Delta robot and linear-driven Delta robot. a Delta robot for pick-and-place operation that forms a crank-slider at the drive joint is designed. To take the most common gate shaped curve in Cartesian space as the motion trail of robotic pick-and-place operation. according to the kinematics inverse solution theory of Delta robot. https://nerdzoics.shop/product-category/home-decor/
