Microgrippers play a crucial role in micro-/nanomanipulation systems dedicated to automatic handling of tiny objects. In this paper, an idea of modular design is proposed to devise a compliant microgripper with two degree-of-freedom (2-DOF) along with parallel translational motion of the gripper arms. A microgripper with 2, 3, and 4 arms is proposed as an illustration. The modular design enables easy...
Chassis is one of the key components of tracked test vehicle. The strength and rigidity of chassis must be considered and structure resonance should be avoided during the process of structure design.
