Biohybrid and Organic Robotics Group (B.O.R.G.)

Lab group logo

Animals have long served as an inspiration for robotics. However, many of the mechanical properties, physical capabilities, and the behavioral flexibility seen in animals have yet to be achieved in robotic platforms. Towards addressing this gap, research in the CMU B.O.R.G focuses on the use of organic materials as structures, actuators, sensors, and controllers towards the development of biohybrid and organic robots. The research group’s long-term goal is to develop completely organic, autonomous robots with programmable neural circuits. Such robotic systems will have future applications in medicine, search and rescue, and environmental monitoring.

Research Overview

Research in the CMU B.O.R.G. focuses on the study and application of organic tissues to create sustainable, biocompatible robotic systems. By studying existing tissues (such as skeletal muscle or neural circuits), we seek to identify design guidelines for bio-inspired and biohybrid robots. We can also use tissues, or cells isolated from these tissues, to grow novel organic systems in order to build biocompatible robots seeking to capture the compliance, behavioral flexibility, and force-to-weight ratios seen in living organisms.

  • Organic structures

    Organic structures

    In living organisms, bio-compatible materials and proteins make-up the structures that support and guide the function of surrounding cells and tissues. The CMU B.O.R.G. uses a variety of bio-fabrication techniques, including additive manufacturing and electrocompaction, to build protein and mineral based structures for robotic systems. Such structures are characterized via mechanical testing and mechanical properties are optimized to support the function of specific cell or tissue types.

    Organic actuators

    Muscle provides many of the functional properties often sought after in robotic applications including natural compliance, energy efficiency, and high force-to-weight ratios. Research in the CMU B.O.R.G. focuses on how to fabricate and support functional muscle tissues that mimic the structure of native muscle in living systems, how different stimulation techniques effect muscle performance, and on creating computationally efficient neuromuscular models for in silico robot design. Our group studies both mammalian muscle (for potential medical applications) as well as invertebrate muscle (for potential environmental monitoring applications).

    Organic sensors

    The sensory systems of living organisms demonstrate amazing specificity and resolution. The CMU B.O.R.G. studies and simulates how the structure and cellular organization of such sensory systems effects cell signaling and how those signals are integrated and processed by the associated neural circuitry. Current research in this thrust focuses on invertebrate sensory systems for aquatic applications.

  • illustration of how organic controllers work

    Organic controllers

    Even relatively “simple” animal nervous systems are capable of robust sensory integration, signal processing, motor control, and complex behavioral flexibility, allowing animals to survive and flourish in complex, dynamically changing environments. Such properties and capabilities are a major goal in robotic control research. The CMU B.O.R.G. studies sensory integration and motor control in invertebrate neural circuits to better understand learning and control with a goal of creating programmed control circuits composed of living neurons for use in organic robots.

    Biohybrid and organic robotics

    In addition to specific research on individual organic systems, researchers in the CMU B.O.R.G. are currently integrating organic and synthetic materials to create Biohybrid and even completely organic robots. The systems combine bio-inspired robotics, bio-fabrication, additive manufacturing, and simulation to create and test biocompatible robots. Our current research focuses on devices that are capable of crawling or swimming in aquatic environments.

    Bio-inspired robotics

    In addition to using living materials to build robotic devices, the CMU B.O.R.G. engages in traditional robotics research and development. We apply principles learned from our studies of the tissues, as well as relevant literature from biology and neuroscience, to create bio-inspired robotic devices and controllers. Our current research projects focus on bio-inspired control algorithms based on invertebrate neural circuits and biologically inspired swimmers.
