My journey in the realm of robotics has been a fascinating blend of creativity, innovation, and hands-on engineering. As a mechanical engineering intern at Embodied Inc. from 2016 to 2019, I had the incredible opportunity to contribute to the development of Moxie, a social robot designed to assist children in building social, emotional, and cognitive skills. This experience not only honed my technical skills but also provided insights into the transformative potential of robotics in everyday life.
Bringing Moxie to Life
Joining Embodied Inc. during its stealth mode phase allowed me to witness and partake in the foundational stages of a groundbreaking project. Moxie, which later received accolades such as the TIME Best Inventions of 2020 and the CES 2024 Innovation Award was more than just a robot; it was a beacon of innovation and hope for many families.
Designing with Precision
One of my primary responsibilities was designing 3D CAD test setups for Moxie’s head structure and arm mechanisms using Fusion 360. This task required meticulous attention to detail and an understanding of the mechanical intricacies that would bring Moxie to life. Each test setup for the head structure, or arm mechanisms were performed to validate design and reliability, ensuring that Moxie could perform its tasks effectively.
Ensuring Structural Integrity
To ensure the durability and reliability of Moxie's components, I performed static stress Finite Element Analysis (FEA) simulations on the designed parts. This step was crucial in validating the strength and stability of the components under various loads and conditions. Based on the simulation results, I recommended design improvements, ensuring that Moxie could withstand the rigors of daily use.
Rapid Prototyping with 3D Additive Technology
One of the most exciting aspects of my role was the ability to manufacture designed parts within the same day using 3D additive technology. This approach significantly reduced lead times by 1-2 weeks, allowing us to quickly iterate and refine our designs. The rapid prototyping process was a game-changer, enabling us to test and implement new ideas swiftly.
Innovating for Uninterrupted Operation
Another critical innovation I contributed to was engineering a special battery charging system for Moxie. This system allowed the robot to operate without motion limitations while being charged, ensuring uninterrupted functionality. This feature was essential for Moxie's role as a companion and helper, as it needed to be available and active at all times.
Enhancing Quality Control
To further improve Moxie's performance, I developed and assembled test setups to validate the DC motor cycle counts. This rigorous testing process improved our quality control by approximately 14%, ensuring that Moxie’s movements were smooth and reliable. By focusing on the longevity and reliability of the motors, we enhanced Moxie's overall user experience.
Reflecting on the Experience
My internship at Embodied Inc. was a transformative period that solidified my passion for robotics. Working on Moxie not only allowed me to apply and expand my engineering skills but also showed me the profound impact that robotics can have on people's lives. From the early design stages to the final testing and validation, every step was a learning opportunity that I cherish.
As I continue my journey in this field, I am excited about the future possibilities and innovations that lie ahead. Robotics is not just about machines and technology; it is about creating solutions that improve lives and drive progress. My experience at Embodied Inc. has been a testament to this belief, and I look forward to contributing to this dynamic and ever-evolving industry.
