Plants inspired scientists to create a robot

In 2014, the team is a team of inventors fromThe Italian Research Center in Genoa has created the Plantoid tree. It is fully printed on a 3D printer and equipped with sensors for measuring temperature, humidity and chemical recognition. A few years later, the team talked about another strange invention - a robot that moves along vertical objects like a climbing plant. How such a robot can be useful is not yet clear, but there are interesting assumptions.

The robot plant is a flexible tube,made from a thermoplastic polymer called polyethylene terephthalate. It does not require a lot of energy, so even a 1.3 volt battery is enough for it to work. The tube is filled with a liquid with a high content of ions - when the robot is energized, these ions are attracted to the bottom of the tube and compress the structure. When the power goes out, the body of the robot is pulled out again.

Before creating the robot, the researchers calculatedthat for more free movement, the thickness of the stem should not exceed 1 mm. At the moment there is no use for it - probably, the small capacity and the utmost fragility of the system have an effect. It is believed that in the future such a robot will be useful in intelligence. It can also be assumed that such a design will become part of wearable devices like wristwatches - for example, their strap will be able to tighten itself.

This is not the only project of a team of researchers. They have already begun the development of the Growbot robot, which can grow depending on environmental conditions. Moreover, the developers claim that he will be able to recognize the types of surfaces.
