Bio-inspired robotics occupies a distinctive intersection between biology and engineering, transforming observations from the natural world into functional, human-made technologies. This discipline has yielded advances ranging from artificial muscles and medical devices to gecko-inspired adhesives and robots capable of running, flying, and swimming. At the University of Colorado Boulder, MCEN 4228/5228: Bio-inspired Robotics introduces students to this rapidly evolving field under the guidance of Professor Kaushik Jayaram.
The course emphasizes that bio-inspired engineering is not simply about copying nature’s solutions. Instead, it focuses on translating biological principles of function, performance, and aesthetics into technologies that address societal needs. “At a very high level, this course is about understanding the philosophy of what bio-inspired engineering is,” Jayaram said. “Since this is a fundamentally interdisciplinary field, we cannot do bio-inspiration in isolation.”
Students engage with a sequence of projects and case studies to explore successful strategies in bio-inspired design. One assignment tasks them with modifying 3D-printed hands using inspiration from an animal of their choice. Starting from a CAD model, they incorporate features that enhance performance. Jayaram notes, “For example, koalas have six fingers – two thumbs on each hand. Some groups get inspiration from that and find their model is better at gripping.” Such exercises encourage mechanical creativity while grounding designs in biological function.
The course culminates in students designing and building their own bio-inspired devices. This process begins with identifying a novel biological discovery that can be adapted for technological application. Past projects have explored enhancements to robotic locomotion, drawing on traits such as webbed feet and fins for improved aquatic movement, or wing configurations that optimize energy efficiency in flight. These designs reflect a direct translation of evolutionary adaptations into engineered systems.
Beyond hardware, students have applied biological insights to algorithms and software. One team modeled how rats use tactile and olfactory cues to navigate complex mazes, developing navigation algorithms for autonomous systems. Another examined the microstructure of leaves and their condensation capabilities, applying the concept to a water filtration device intended for arid environments. These examples illustrate the breadth of inspiration—from animal physiology to plant morphology—and the applicability across both physical and computational domains.
“There is a wide range of examples from animals to plants and in both hardware and software,” Jayaram said. “Somebody who is working in this field needs to have a strong understanding of biology, a strong understanding of different kinds of engineering and potentially have an understanding about art, ethics and society.” This holistic perspective underscores the importance of interdisciplinary fluency, as effective bio-inspired solutions often require integration of mechanical design, materials science, and systems engineering with an awareness of societal context.
The inventive processes fostered in Bio-inspired Robotics equip students for diverse career paths, including roles in robotics, biomedical engineering, and aerospace systems. The creative dimension of the work also strengthens entrepreneurial potential, as students learn to identify unmet needs and devise novel solutions grounded in natural principles. The course’s approach mirrors trends in advanced engineering sectors, where biomimicry informs innovations such as micro-drone wing structures modeled on insect flight or soft robotic actuators inspired by cephalopod tentacles.
Jayaram envisions expanding the course to include students from outside the sciences, such as those in business, humanities, and the arts. This reflects the field’s inherently interdisciplinary nature and the value of diverse perspectives in problem-solving. Currently, enrollment is open to juniors, seniors, and graduate students in mechanical and biomedical engineering, as well as those studying engineering management.
By engaging with both the technical rigor and the creative inspiration of biological systems, participants in Bio-inspired Robotics gain a toolkit for designing technologies that are efficient, adaptive, and responsive to real-world challenges.
