Design a low-cost delta robot arm for pick and place applications based on computer vision

Autor: Phuong Hoai, Vo Cong, Thai Hiep

Publikováno v: FME Transactions. 51:99-108

In this paper, we develop a low-cost delta robot arm for grasping objects of unspecified size thanks to a vision system. Stepper motors are used instead of ac servo motors to build a low-cost delta robot arm. Furthermore, we use available materials a
