Assignment: Mechanical Design of a

Robotic Arm

Assignment Overview

In this assignment, you will delve into the world of robotics by designing a robotic arm.

This project will integrate concepts from dynamics and robotics, providing you with

hands-on experience in applying theoretical knowledge to practical engineering tasks.

The assignment will be worth 40% of your unit grade in ENG721.

Assignment Objectives

• Apply principles of dynamics to analyze the motion and behavior of robotic arms.

• Design a robotic arm using CAD software, considering factors such as kinematics,

workspace, and payload capacity.

Assignment Tasks

1. Literature Review (15%)

• Conduct a literature review on the principles of dynamics in robotic arm design.

• Summarize key findings and relevant methodologies in a written report.

2. Robotic Arm Design (25%)

• Design a robotic arm using CAD software (Ansys Discovery Modeling Tutorial -

Robotic Arm Geometry - Lesson 8 - ANSYS Innovation Courses).

• Considerfactorssuchaskinematics,jointtypes,degreesoffreedom,andend-effector

options.

• Optimize the design for efficiency, accuracy, and structural integrity.

Submission Requirements

• Written Report: Provide a comprehensive report detailing the design process,

implementation challenges, and performance evaluation results.

1

• Video Demonstration: Record a video demonstration showcasing the robotic

arm’s operation and task execution.

• Ansys File: Provide a comprehensive Ansys file.
