Kinematic Analysis of a Novel 5-DOF Delta-type Parallel Robot

Nowadays, various Delta-type robots are widely used in many technological fields. In this work, we propose a novel 5-DOF Delta-type parallel robot with four linear and one rotational actuators. The major part of the article is devoted to the kinematic analysis of the robot, including solving its inverse and forward kinematic problems. To demonstrate the developed techniques, we consider two numerical examples. In the first one, we solve the inverse kinematics and determine the actuator displacements required to realize a spatial trajectory of the output link. The forward kinematic analysis, presented in the second example, results in six different assembly modes of the robot for the given set of the actuator displacements. The proposed algorithms represent the basis for subsequent velocity, acceleration, and dynamic analysis of the robot, and they can be adapted to other Delta-type parallel robots.
