Princeton University researchers have made groundbreaking strides in the field of robotics with the development of the eViper soft robot. Unlike traditional robots that rely on legs or rotary parts, this innovative creation uses actuators to convert electrical energy into vibrations, propelling the robot forward without the need for any rigid components. The eViper represents a significant shift in the fabrication and powering of soft robots, which are designed with flexible bodies to perform complex tasks.
Soft robots, with their potential applications in various fields such as surgery and space exploration, present unique engineering challenges. Designing and controlling soft bodies require a different approach than traditional rigid-body robotics. Recognizing this, the Princeton team has published several papers on their research and development efforts over the past year. Their latest paper, presented at the prestigious 2023 IEEE International Conference on Intelligent Robots and Systems (IROS), was even nominated for a best paper award.
This impressive soft robot operates based on the principles of the piezoelectric effect. By converting electrical energy into mechanical energy through carefully timed pulses, the eViper’s flexible body can bend and propel itself in different directions. The team utilized advanced power electronics designs and integrated sensors and control systems to create a fully untethered soft robot that achieves energy efficiency comparable to land animals. With its high energy efficiency, the eViper platform provides a promising foundation for future robotic systems that will meet the increasing demand of the industry.
“Future robotic systems need high energy efficiency,” emphasized Minjie Chen, one of the project’s principal investigators and an assistant professor of electrical and computer engineering. “The eViper platform enables us to explore electrical, mechanical, and power co-design to maximize energy efficiency.”
The eViper soft robot represents a significant milestone in the field of robotics, paving the way for more energy-efficient and versatile robotic systems. Its unique design and use of piezoelectric effects bring us closer to a future where advanced robotics play a pivotal role in various industries. The potential applications of this technology are vast, and its impact will undoubtedly reshape the field of robotics as we know it.
