A Bioinspired 2-DOF Throwing Robot

A bio-inspired throwing robot with two degrees of freedom (DOF) was developed for a science center. It has a rotary axis to turn the robot like a human his body and a second rotary axis to throw objects like a human with his arm. With this kinematic, the robot is capable to throw objects into predefined positions within a given 3D-space. The goal of this robot is to demonstrate visitors in the science center robotic throwing with a simple kinematic. In experiments the visitors can learn how the angle of throwing and the speed of throwing determines the trajectories of thrown objects. Student-classes who want to spend more time for the robot can also calculate such trajectories. Therefore, the required mathematical models for this robot are also presented in this paper.
