The robot learned to save energy like sloths

When you create robots engineers are often inspired by real animals — they are often borrowed both the anatomical and the chemical-biological characteristics. For example, graduates of the Georgia Institute of Technology drew attention to a surprising feature of the sloths to settle for the minimum amount of food and energy due to a sedentary lifestyle. Creating a small robot and teach him to commit a very slow and not demanding energy of motion, they made him virtually immortal.

The development of a robot engaged students Gennaro Neotomista Yousef and Eman under the guidance of Professor Magnus Egerstedt. Their main goal was to create a robot that commits a minimum of movement and thereby consumes a very small amount of energy. Ideally, maintenance should have been enough daylight energy to create such a technology the developers have really succeeded.

Robot sloth with lots of energy

Basically the robot consists of a printed 3D-printed gears and other parts designed for the holding structure on the strained ropes. According to the developers, the robot hanging between the tops of the forest trees and giving him the opportunity to slowly move the cables, they can spend months to observe wildlife.


Since the robot will only move if absolutely necessary, its charge should last for a very long time. In extreme cases, it has solar panels that keep the battery in a charged state. According to Professor Magnus Egerstedt, physical movements require much more energy than the brain and sensory organs. Minimizing the motion of the robot, they were able to achieve the maximum battery saving.

Soon the robot will be tested on the cocoa plantation in Costa Rica to move you will use cables for the transport of cocoa. Also the robot will be tested in the Atlanta Botanical garden, where you will be in charge of monitoring the state of the environment. Before these tests developers will have to equip the construction of a solid body, because in the prototype there is a lot of exposed wires.

Sometimes engineers pay attention not only on the characteristics of animals, but also on the behavior of plants. For example, in early 2019, the researchers from the Italian research centre in Genoa has created a robot that climbs the objects as a climbing plant.
