- Project Title: AP Research: Evaluating the Effect of 3D Printed Robotic Arm Designs on Structural Integrity, Cost, and Efficiency
- BASIS Independent Advisor: Ms. Nagpal
Numerous companies are working to build robots that can move autonomously and tackle a wide variety of situations, from assembly line manufacturing and packaging, to open-world applications like remote terrain exploration. Currently, to interact with the environment, most companies use robotic arms designed out of metal, for its numerous structural benefits and useful physical characteristics. However, this comes at the expense of increased material and manufacturing costs. Recently, some research has started to explore the characteristics of robotic arms fabricated using 3D printing, but there has yet to be a conclusive study evaluating the different types of designs. Furthermore, 3D printing introduces several factors that are absent in metals: infill patterns (specifying how hollow to make the printed object, in order to save weight), rapid prototyping (negating the need to painstakingly manufacture custom molds for every prototype), and near-infinite variety of materials. In my research, I hope to assess these expected benefits of 3D printed robotic arms, comparing them to the already-researched performance of metal robotic arms. My methodology involves drawing from the existing literature to create several robotic arm designs using CAD software. Then, I will fabricate some of these designs, 3D printing and assembling the parts and electronics. Finally, I will install a force sensor and accelerometer on these prototypes, to measure the maximum load and maximum speed each prototype can handle.
