A robot starfish will help you explore the depths of the ocean

The researchers explained that documenting life in the ocean is a very difficult and expensive process. IN

primarily because the equipment for this must be durable, but its design should not disturb marine life, which are sensitive to human movements.

As a possible solution, scientists have developednew marine robot. The team used their system to create a soft robotic starfish made from silicon foam; the device can be moved using one low-power motor. The star is driven by tendons in the limbs, which are connected to a servo.

The researchers chose the design of the star because ofsimplicity and elegance of movements. However, in the future they want to create the same robots with a different body structure - which are inspired by the body of sea turtles, rays, sharks. These will include joints, fins, and flippers.

Scientists first built a teaching model thatperforms the initial simulation and design of the robot's control mechanisms, then the prototype itself was quickly produced. Researchers later experimented with the robot to gain more data to improve and optimize its design. As a result, the robot usually only needs to be reworked once.

“When modeling a robot, we have to dochanges that, by definition, create a gap between simulation and reality, the scientists noted. “Our future work is aimed at narrowing this gap between reality, with a mixed cycle of simulation and real-life experiments, which, as it seemed to us, are quite effective.”
