Octopus-inspired Rocket is one nimble robotic underwater creature
Octopus is one of the smartest creature on planet earth, and no wonder intellectuals have tried to mimic its intelligence beyond comprehension. Researchers at FORTH tried to mimic the movement of octopus in water by developing a robot dubbed Octobot, having webbed tentacles with success. Now, another similar kind of octopus-inspired robot developed by Gabriel D. Weymouth and Mr Vignesh Subramaniam, Singapore-MIT Alliance for Research and Technology (SMART) research engineer has come to light. This endeavor deemed as Octopus-inspired Rocket is slightly better than the effort by FORTH researcher D. Tsakiris, since this robotic octopus can propel 10 times its body length in just 1 second flat.
This swift robot is inspired by the cephalopods octopus which are equally rapid underwater, as it uses the mantle cavity to fill body with water and use it to thrust away whenever danger is sensed. This 27 cm long robot with a 3D printed body has a similar thin elastic membrane which fills with water and then releases it to move forward in a jiffy. To make sure that the robot has controlled movement inside water, there are fins and tail to stabilize the movement.
The effort is a part of research for autonomous underwater vehicle (AUV) development that will be the future of underwater research. For example venturing into deep underwater places where it is impossible for humans to venture out due to temperature variation or atmospheric pressure.
