Minirrobot water in water

Miniature swimming robots, which are the fascinating area of ​​modern robotics and nanotechnology, are devices designed to move in liquid environments. Size allows them to perform important tasks such as pollution mapping, water ecosystem work and water quality monitoring.

However, existing models are still interested in some limitations in their designs, especially in the propeller drive systems It can disturb water animals and may even cause physical damage when contact. In addition, the complexity of the environment can cause permanent damage to propellers or sensors filled with detrite vegetation.

Now, in a new study published in Science Robotics Magazine, a press release includes a compact and versatile robot model that can maneuver in narrow spaces and carry much more heavy loads. Small robot, which is just six grams and smaller than a credit card, is suitable for limited areas.

Building a auspicious minirrobot from scratch

Experts in the manufacturing of miniaturized robots, Federal Polytechnic Lausanne, Soft Transducers Laboratory Engineers from the Swiss Federal Polytechnic School have already developed insect -in -insect robots, but without cable -thin robots have capacity to operate in obstacles. With the obstacles, it was a completely new challenge, Herbert accepts the head of Shea Lab.

“We had to start from scratch, we had to develop more powerful soft actuators, new wavy motion strategies and high -voltage compact electronics, Rard he explains. Unpublished design not only repeats nature, but also goes beyond the achievement of natural organisms, says Florian Hartmann.

The big difference of water robots developed in EPFL is that there is no propellers.: Use similar fins to properly fluctuating sea worms (plants). In addition, the method is silent, ie they can perform environmental monitoring and water life studies without disturbing the ecosystem.

By equipping its robots with a pair of pectoral fins that swing with 10 times faster than the eyelashes of the original plateau, EPFL engineers showed an impressive speed of 12 centimeters per second, which is equivalent to 2.6 body length.

In addition to being fast, robot 5.1 centimeters linear movements (translations) and 195 degree circular (rotations) per second perform maneuverability which is defined by authors as unprecedented. The fins are triggered by four artificial muscles. Robotic mini -Currents can swim back and forth, and can rotate in a controlled manner.

A compact control system (the internal brain of the robot) 500 Volt Delivery for Actuaries Using Only 500 MilewattsAccording to a statement, four times lower than an electric toothbrush. Although the voltage is high, low currents and armored circuits damage the risks of overheating and electronic components as well as environmental safety.

How to use Minirrobots-Platelminthos?

The authors used experimental studies and modeling to determine ideal dimensions and working conditions for robots of different designs and scales. In tests, they can sail for narrow spaces, pass grass plants and push objects more than 16 times their body weight. This allows them to monitor real -time plant growth and water quality in aquaculture systems.

However, the researchers believe that the robot can revolutionize in areas such as ecological studies, pollution monitoring and sensitive agriculture. For this, the team is preparing a new, more robust platform for field tests. The aim is to increase the efficiency and practical applicability of the device in real scenarios.

The expectation for Hartmann is to expand the working time and autonomy of the robot. “The insights obtained not only advance the bio -exhaled robots, but also form soles for practical and sustainable robot systems, It can be integrated with nature in harmonyTo encourage significant progress in various scientific and technological fields. ”
