3、OF A HIGH PERFORMANCE SCARA TYPE ROBOTIC ARM WITH ROTARY HYDRAULIC ACTUATORSABSTRACT:This study proposes a Selective Compliant Assembly Robotic Arm (SCARA) with two revolute joints for poultry deboning. The joints of the

4、 arm are based on two high performance rotary type hydraulic actuators. These actuators are operated by servo valves, which control hydraulic fluid flow and direction. A PID based independent joint control system is cons

5、idered for controlling the position of each joint. The system was modelled using the MATLAB - SIMULINK toolbox. Thesimulation results show that the arm was capable of covering a work envelope of 0.9 m x 0.9 m, reaching c

6、ontrolled velocities of up to 7.5 m/s with an average of 5.8 m/s. Obtaining such high speeds and torques would be a difficult task with electrical actuators of the capacity as the hydraulic counterparts considered here.I

8、image is taken by a X-ray camera. A computer will analyze the image and generate the desired position coordinate position (x,y,z) of the bone. This study pro- poses a Selective Compliant Assembly Robot Arm (SCARA) with t

11、-oscillatory. After the blade is moved to the desired (x,y) position in the horizontal plane, an actuator fixed to the prismatic joint will be activated in the z-direction in order to remove the bone. The end effector is

12、 capable of covering an area of approximately 0.9 m x 0.9 m.In this study we propose a model for the operation and control of a SCARA robot with double vane rotary type servo- hydraulic actuators. The proposed system was

13、 simulated and the performance was evaluated. This paper will also demonstrate its capability for high speed precision control of the end effector. It is also intended to justify why hydraulics were selected, although el

14、ectrical motors are commonly used in industry today. Based on simulation results we estimate the dis- placement coefficient or volume of the rotary hydraulic actuator required for this purpose. A suitable design for the

15、actuator is proposed next. Finally, a design of the complete SCARA arm with its components is presented.This paper is organized as follows. A brief introduction and an insight to the research topic is presented in Sectio

16、n 1. In Section 2, The theory and methodology used in modelling the system are presented. The results of the simulated system for the SCARA arm are presented next section. In Section 4, the details of the actuator design

17、 and the SCARA arm assembly are presented. In Section 5, the conclusions and avenues for future work are given.2.PROBLEM FORMULATION AND THE DYNAMIC MODELThe proposed SCARA type robotic arm consists with three degrees-of
