In this study, a SCARA Prismatic-Revolute-Revolute-type (FRB) robot manipulator is designed and implemented. Firstly, the SCARA robot is designed in accordance with the mechanical calculations. Then, forward and inverse kinematic equations of the robot are derived by using D-H parameters and analytical methods. The software is developed according to the obtained Cartesian velocities from joint velocities and joint velocities from Cartesian velocities. The trajectory planning is designed using the calculated kinematic equations, and the simulation is performed in MATLAB VRML environment. A stepping motor is used for the prismatic joint of the robot, and servo motors are used for revolute joints. While most of the SCARA robot studies focus on the Revolute-Revolute-Prismatic -type (RRP) servo control strategy, this work focuses on PRR, type and both stepper and servo control structures. The objects in the desired points of the workspace are picked and placed to another desired point synchronously with the simulation. Therefore, the performance of the robot is examined experimentally. (C) 2020 Sharif University of Technology. All rights reserved.
