Vision-based polar coordinates robot
Abstract: In assembly robots, ball coordinates type assembly robot (namely polar type) is a kind of very extensive assembly robot. The main task of this project is to design vision-based polar coordinates robot. The main transmission scheme: grasping intensify institutions with linear motor drive, stepped chute mechanism; wrist rotation using stepper motor drive; horizontal telescopic movement driven by a stepping motor, ball screw drive; pitch movement using stepper motor drive, ball screw drive; big arm rotational motion using stepper motor drive. Visual aspects use the industrial camera. The various drive and visual systems assembly can achieve the visual design of the polar coordinates of the robot.
The paper presents the design of industrial robot ball coordinates type has the
following characteristics: the mechanical arm high universality,small volume,light weight,good appearance,suitable for observation,low cost and feasible scheme for its ontology adequate argument.
