Artimus Robotics is dedicated to advancing actuator technologies to enhance the field of robotics. They are developing high-performance soft artificial muscles inspired by nature. These actuators are known as hydraulically amplified soft electrostatic actuators, or HASEL actuators for short.
In the summer of 2022, I was hired as a research and development intern. This was an exciting opportunity, as the HASEL actuator had influenced my decision to attend the University of Colorado Boulder. I primarily worked on developing wearable technologies that incorporated these actuators. My experience in costume-making and sewing made me well-suited for creating wearable devices.
Interns were paired with senior engineers who acted as mentors. My mentor, Eric Alcome, assigned me a variety of projects that required different skills and methodologies. This diversity helped me become a more well-rounded engineer. The experience I gained from prototyping and other assignments has been invaluable to my growth as an engineer.
Demonstration of E-series expanding
Repair & Redesign
The first project I was assigned involved repairing and redesigning product demonstrations. While the E-series demo required only minor repairs, the C-series demo needed a significant redesign. The main issues with the C-series demo were damage during transportation and its large packed footprint. I was given a carrying case and tasked with packing both demos and preventing damage while traveling.
To tackle this problem, I conducted an internal survey to identify which parts of the demo were most vulnerable to damage. The survey revealed that the demo's legs were particularly susceptible to breaking. I ultimately decided to design removable modular legs. Although this change reduced its footprint, the demo was still too large for the case. With this in mind, I redesigned the body of the demo to be as compact as possible.
With the new design, I devised a packing system that fit and secured the demos in their travel case. Since the demos now required assembly, I thought it was imperative to provide clear instructions. I created detailed written instructions for assembly and packing, complete with photographs. Additionally, I took the initiative to record video tutorials to further assist with these processes.
Throughout this project, I gained valuable technical experience in laser cutting, resin printing, and understanding how manufacturing tolerances vary among different materials and processes. I also developed my written and visual communication skills.

Compression Device Prototypes
Initial research is essential in the prototyping process. I aimed to gather thorough background information by investigating similar products, their daily applications, and suitable materials. I developed sewing patterns through paper testing, making adjustments before using more costly materials. I documented these patterns in Adobe Illustrator for future use.
For the initial design, I used an existing brace and integrated E-series actuators with a series of pockets that also protected the wearer’s skin. I chose a moisture-wicking liner for comfort, a water-resistant outer shell, and grommets to accommodate wiring.
However, the initial model lacked size inclusivity and had an inner foam structure that absorbed too much motion. In the second iteration, I removed the foam, created a new base accommodating calf sizes from 12 to 24 inches, and added more fastening straps.
Testing these designs was a new challenge, and I initially overlooked a variable that affected test validity. I acknowledged this in my team presentation, emphasizing the need for further testing.
As my position was short-term, thorough documentation of my work was crucial. I organized my contributions by topic and included all supporting documents and notes, which enhanced my written communication and organizational skills.

SOP Development
During onboarding, training was fast-paced, and my ability to learn quickly proved to be beneficial. Once my training was complete, I was entrusted with writing a Standard Operating Procedure (SOP) for a manufacturing process alongside my other projects.
To create an accurate SOP, I performed the processes I was documenting. During this practice, I made a mistake I didn't know how to correct. Instead of trying to cover it up, I asked my supervisor for help, and he guided me in resolving the issue. Recognizing that others might also make this mistake, I documented the solution in the SOP. By including contingencies for common errors, I improved its quality. This experience also helped me develop clear written communication skills and sharpened my attention to detail.
Throughout my academic career, I discovered that I preferred clear, detailed instructions. I've noticed that others are more likely to follow instructions correctly when they are well-detailed. While writing the SOP, I applied this insight by including pictures, step-by-step instructions, and helpful tips I had learned. This experience taught me that seeking help and gathering knowledge from experts can minimize the negative impact of mistakes and lead to positive outcomes.
