Abstract

Considering that the Jacobian matrix maps the velocity of the joint space of the robot to the end velocity of the Cartesian space, a novel topology optimization approach is proposed in this article...

Highlights

  • In the past two decades, compliant mechanisms are widely used in precision engineering as they do not show problems such as clearance, friction, and wear.[1]

  • To improve the overall stiffness of the compliant mechanism, the topology optimization approach has been used in its design

  • Compared with multi-input and multi-output (MIMO) of parallel prototype manipulator, the singularity of driver configuration should be considered at the beginning of topology optimization process of spatial compliant mechanism
