Abstract

The American Society of Mechanical Engineers (ASME) 2017 Design Challenge is modeled after the 2016 Rio Olympics. Participants must build a robot to compete in Olympic style events. These Olympic events include a 10 meter sprint, golf ball hit, tennis ball throw, weight lift and stair climb. The sprint and stair climb event success is measured by time elapsed to complete the event. The weight lift is measured in weight lifted multiplied by height lifted, Newton-meters. The golf ball hit and tennis ball throw are evaluated by distance from robot. A robot was designed to meet this criteria. Analysis methods of statics, dynamics, and machine design were used to create the basis of minimum performance standards for each mechanical system. The robot was built primarily of VEX Robotics parts, and of 3D printed custom designed parts. Mechanical systems are also required to have a failsafe position to ensure safety of robot drivers and spectators. During construction of the robot, several design changes were made to accommodate space allowances and clearance issues between mechanical systems. The robot was tested at the ASME Student Design Expo at Central Washington University, where it competed against robots made by other university participants. The robot is considered successful as it falls within 10% of the expected performance parameters for each event.
