As the
field of soft robotics advances, the scientists envision these robots being used for marine search and rescue, oceanic temperature sensing, and military surveillance.
In the
field of soft robotics, the material could facilitate advances in the production of responsive, self - correcting artificial muscles.
The Soft Robotics Toolkit is an online treasure trove of downloadable, open - source plans, how - to videos, and case studies to assist users in the design, fabrication, modeling, characterization, and control
of soft robotic devices.
Researchers hope that rethinking materials, fabrication techniques and design strategies should open up new
areas of soft robotics in micro - and millimeter length scales, including swimmers (both on - surface and underwater) and even fliers.
The Soft Robotics Toolkit is a collection of shared resources to support the design, fabrication, modeling, characterization, and
control of soft robotic devices.
The team coated the
fingers of a soft robotic gripper with the gecko adhesive, allowing it to get a firmer grasp on a wide range of objects, including pipes and mugs, while still being able to handle rough objects like rocks.
«This approach could inspire better surgical training tools and implantable heart devices, and opens new possibilities in the emerging field
of soft robotics for devices that assist other organs as well.»
«The goal of the toolkit is to advance the field
of soft robotics by allowing designers and researchers to build upon each other's work,» says Conor Walsh, Assistant Professor of Mechanical and Biomedical Engineering at the Harvard School of Engineering and Applied Sciences (SEAS) and a Core Faculty Member at the Wyss Institute for Biologically Inspired Engineering at Harvard University.
Using principles drawn from conventional rigid robot design, but working with pliable materials, engineers are pioneering the
use of soft robotics for assisting in a wide variety of tasks such as physical therapy, minimally invasive surgery, and search - and - rescue operations in dangerous environments.
Coating the
inside of the soft robotic fingers with these adhesives maximizes the amount of surface area they make contact with, ensuring a better grip.
«We're now working to improve both the control and the power of these devices, to advance the
potential of soft robotics,» Tracy says.
The Toolkit includes an open source fluidic control board, detailed design documentation describing a wide
range of soft robotic components (including actuators and sensors), and related files that can be downloaded and used in the design, manufacture, and operation of soft robots.
Robotics has come on in leaps and bounds in just a few short years, especially in the field
of soft robotics where researchers are building everything from lifesaving sleeves for hearts to powerful exosuits.
It could also create a new
area of soft robotics, and enable new applications in flexible sensors and actuators, biomedical devices and platforms or scaffolds for cells to grow, Lee said.
The ultimate aim of the Toolkit is to advance the field
of soft robotics by allowing designers and researchers to build upon each other's work.
«This research demonstrates that the growing
field of soft robotics can be applied to clinical needs and potentially reduce the burden of heart disease and improve the quality of life for patients,» said the paper's lead author Ellen T. Roche.
Roche hopes the sleeve can serve as a landmark improvement in the growing field
of soft robotics:
The emerging field
of soft robotics is helping to make robots safer, but recreating muscle is no easy task.
«It can also be very important in the prospective field
of soft robotics, where having conventional rigid components is undesirable as they can break or constrain motion when the soft robots get curved or twisted,» Bermudez continued.
