Group Assignment: Machine Design

Introduction

This week's group assignment focused on designing and building a five-axis robot arm with interchangeable tools at the end effector. The robot arm is intended to perform tasks such as milling and isolation routing. The project was divided into teams, each responsible for specific aspects: circuit design, mechanical design, firmware development, and interface design. This collaborative effort aimed to integrate these components into a functional and versatile robotic system.

The Team

Mechanism

We used SolidWorks to design a 5-axis machine with stepper motors at each joint. The design process involved creating a detailed 3D model of the machine, ensuring precise alignment and functionality of all components. The stepper motors were strategically placed at each joint to provide accurate and smooth motion control. Materials were selected based on strength and durability, and the assembly steps were carefully planned to ensure proper integration of all parts.

Actuation

Explain the actuation system used in the machine, including the type of actuators, their placement, and how they function.

Automation

Detail the automation aspect of the machine, including the programming, sensors, and control systems used.

Application

Discuss the intended application of the machine and how it fulfills the project requirements.

Manual Operation

Describe how the machine can be operated manually, including any specific instructions or considerations.

Documentation

Provide detailed documentation of the group project, including challenges faced, solutions implemented, and lessons learned.

Conclusion

Summarize the project outcomes and reflect on the overall experience of designing and building the machine.
