Abstract
In this study, structural and dynamic analyses were applied to the mobile transportation robot to find the structural strength and to calculate the power and torque requirements. The mobile transportation robot was designed using CAD software as two modules; mecanum wheeled locomotion module and robotic arm module, respectively. The analyses were carried on the CAE Software using the static structural and rigid body dynamics tools. In the structural analysis, the weight of the robot and the additional load (98.1 N) were applied to the body of the robot. The material of the robot body was selected as Aluminum 6061 O sheet metal. In the dynamic analysis, the operation environment and conditions were simulated in the CAE software. The structural analysis results showed that the factor of safety value was obtained as 10.282 under applied loads and this value indicates that the chassis of mobile transportation robot is supposed to carry loads reaching up to 30 kg without any functional and mechanical problem. Furthermore, from the dynamic analysis, the total torque requirement of the mobile robot was about 16.56 Nm.
