Design And Optimization Of A Robotic Arm Using Advanced Materials

Abstract

This Project highlights the importance of digital prototyping over traditional prototyping in manufacturing
engineering. In today’s fast paced industrial era, every company strives for speed and efficiency in
manufacturing to meet client demands, with the agricultural sector being a notable exception. Robots now
perform tasks more quickly, cost effectively, and accurately than humans ever could. The moving parts of a
robotic arm experience significant elastic deformations and stresses, often operating at ve locities comparable to
the tool itself. This project focuses on the shearing operation, with the primary challenge being the design and
optimization of a lightweight robotic arm component that is both durable and reliable. Through extensive study,
we have developed and analysed a jointed robotic arm where the base remains fixed, and the remaining joints
can move vertically and horizontally. The design and analysis were conducted using three different materials:
Epoxy Carbon Woven, Steel Alloys , and AL NI . A force of 4000N was applied to the robotic arm to evaluate its
structural and thermal performance. Ultimately, the study identifies the most suitable material among these three
options for use in the robotic arm.
