Create a short (30 sec.) movie that showcases the action of the Fanuc robotic arm using the files provided. Your movie should move the camera or perspective in space to view the model from multiple angles during each of the following non-overlapping segments:

· Disassembly/reassembly of the model.

· Demonstration of range of motion. All four joint angles must move through a representative range of motion.

Create a virtual domino course using the parts provided. Your course should feature at least a dozen dominos in a sequence that features, at a minimum, two 90-degree turns. Save a motion study as a movie file in which all dominos are knocked over.

Extra Credit: Apply appearances to the dominos, surface, and scene. Render the video to make it photorealistic. Consult the Photoview 360 tutorial for more information on how to render.

What to submit:

· Movie files for both the robotic arm motion and the domino course (saved as .AVI files)

· SolidWorks files for the dominos and oscillator (saved as Pack-and-Go .ZIP files, with simulation results included)

· A 2-3 page report, including figures and tables, on your oscillator motion analysis that addresses all of the posed questions.

Sample Paper For Above instruction

The primary objective of this project is to demonstrate proficiency in creating animated motion studies in SolidWorks, focusing on mechanical assemblies. The assignment encompasses two distinct tasks: creating a detailed animation of a Fanuc robotic arm and designing a virtual domino course that exemplifies sequential motion. Both tasks require a combination of technical modeling, motion analysis, and rendering skills, culminating in professional-quality video outputs and comprehensive documentation.

Introduction

SolidWorks is a powerful CAD software that allows engineers to simulate and animate mechanical systems, aiding in visualization and presentation. The project outlined emphasizes the capabilities of SolidWorks motion studies, particularly in simulating assembly/disassembly sequences and complex kinematic motions. The robotic arm animation not only illustrates the range of motion but also integrates camera movements to enhance visualization from multiple perspectives. Meanwhile, the domino course demonstrates dynamic interactions and the effects of gravity and momentum within a controlled virtual environment.

Robotic Arm Animation

The first part of the project involves creating a 30-second animation of a Fanuc robotic arm. The key challenge is to accurately model the arm's motion, disassembly, and reassembly while showcasing the full operational range of the four joints. The process begins with familiarizing oneself with the model, understanding joint limits, and unsuppressing joint mates to facilitate movement. An exploded view aids in visualizing the disassembly sequence, which is animated through predefined explode steps. To achieve smooth motion, keyframes are set at strategic points for each joint, allowing the arm to transition seamlessly through various positions.

Camera perspectives play a vital role in highlighting different aspects of the motion. By creating multiple keyframes with varied orientations, the animator can effectively demonstrate the arm’s flexibility and operational envelope. Using the Animation Wizard simplifies the incorporation of explosion and collapse sequences, and previewing the animation helps ensure motions are natural and free of jerks. Fine-tuning initial conditions through multiple recalculations ensures accurate positioning, especially during large angular displacements.

Domino Course Simulation

The second part of the assignment involves designing and animating a domino chain with at least a dozen pieces. Proper mate configuration is essential to allow realistic motion—overly restrictive mates can hinder natural falling sequences. The pattern incorporates at least two 90-degree turns, adding complexity to the setup. Utilizing linear and circular patterns expedites the placement of domino copies, but these patterns must be dissolved to create independent objects amenable to motion analysis. Assigning a motor to the first domino allows for initial tilting, after which gravity propagates the collapse through the chain.

The motion study captures the chain reaction, with the dominos falling sequentially until the last piece is toppled. Careful mate management ensures that the dominos interact correctly during the simulation. Adjusting parameters such as motor angle, gravity, and the timing of falls can influence the realism of the animation. For extra credit, appearances and scene settings can be enhanced to produce photorealistic rendering, offering a convincing visualization of the domino effect.

Discussion

This project exemplifies the integration of solid modeling, motion analysis, and rendering within SolidWorks. The robotic arm animation demonstrates the importance of precise mate configurations and effective camera control to produce compelling visualizations. Likewise, the domino chain emphasizes the significance of mate management and pattern features to efficiently create complex systems that behave realistically under simulated physics.

The capacity to animate mechanical motions not only aids in design validation but also enhances communication with stakeholders. The added step of rendering photorealistic videos elevates the presentation quality, making the results suitable for professional demonstrations and reports.

Conclusion

Through this project, students develop critical skills in SolidWorks motion studies, including assembly/disassembly animations, kinematic analysis, and photorealistic rendering. The dual tasks of animating a robotic arm and constructing a domino cascade highlight the diverse applications of CAD animation tools. Mastery of these techniques fosters a deeper understanding of mechanical behaviors and effective visualization strategies.
