New Tail-Flapping System Enhances Efficiency of Underwater Robots
Scientists at the University of Bristol have developed a new tail-flapping system for fish-like underwater robots. The system, which uses a modified version of a mechanism known as a twisted and coiled polymer (TCP), offers an energy-efficient and speedy means of propulsion. The team, led by PhD student Tsam Lung You, incorporated the system into a robotic fish to demonstrate its effectiveness.
Understanding TCPs
Twisted and coiled polymers (TCPs) are coiled lines that contract and relax like muscles when heated. When heated, the line tightens and coils, and when the heat is removed, it returns to its default length. While TCPs are effective at producing movements, they have limitations when it comes to repetitive movements due to the time required for them to contract again.
Overcoming the Limitations
The robotic fish developed by the researchers addresses this limitation by combining a conductive-yarn TCP with a conventional steel coil spring. Both these components are placed along the length of the robot and connected to a tail-flapping mechanism. An electrical current is applied to the TCP, causing it to heat up, contract, and pull the tail to one side, while simultaneously stretching the coil spring. When the current stops, the TCP relaxes, and the spring contracts, pulling the tail to the other side. The cycle continues as the TCP contracts again.
Improved Speed and Movement
In underwater tank tests, the robotic fish was able to achieve a tail-flapping rate of two waves per second. This is significantly faster than previous real TCP applications. The researchers are now working on incorporating this technology into a more agile robotic knifefish, which has a fin running along its underside.
Promising Applications
The development of this new tail-flapping system opens up more opportunities for TCP application in various areas. The system offers a more energy-efficient and speedy means of propulsion for underwater robots. It has potential applications in fields such as marine exploration, underwater surveillance, and environmental monitoring.
Presentation of Research
The research on the new tail-flapping system was presented at the 6th IEEE-RAS International Conference on Soft Robotics. The team showcased the robot and its capabilities in a video demonstration.
Conclusion
The University of Bristol scientists have developed an innovative tail-flapping system for underwater robots that improves their efficiency and speed. By combining a conductive-yarn TCP with a conventional steel coil spring, the system allows for repetitive movements at a fast rate. This breakthrough has the potential to revolutionize underwater robotics and find applications in various industries. Further research and development in this area will lead to even more advanced underwater robotic systems.
