American engineers modified the design by moving the cables of the robot sloth SlothBot and began testing. In the next few months, the robot will pass the test at the Atlanta Botanical garden, reported on the website of the Georgia Institute of Technology.
People don’t always need a fast and powerful robots, there are tasks for which the ability for a long time to gather information is much more important than mobility, for example, that is the task of robotic buoys. However, things are more complicated if the robot has to periodically move from place to place, as in this case, you need to find a solution that, on the one hand, is unpretentious, and with another — will not power intensive. Ground robots are not well suited for this purpose (on the earth can meet a variety of obstacles), and flying robots are basically unable to stay in place, without spending energy. One intermediate solution is to suspend the robot above the ground on a rope.
Did the engineers from the Georgia Institute of Technology under the leadership of Magnus Egerstedt (Magnus Egerstedt). They presented last year’s robot sloth for environmental monitoring. It is powered by solar panels and capable of a long time hanging in one place, collecting information and, if necessary, the robot sloth can move on the rope.
Now a group of Egerstedt presented the second, revised version of a robot SlothBot, and began field trials. The developers have provided the device housing a total length of 90 cm — the robot-sloth got a head, torso, and even decorative clutches.
Tests of the robot are in the Atlanta Botanical garden, where it measures the temperature, monitors the weather and the level of carbon dioxide in the air. Most of the time the robot sloth hanging motionless at the 30-meter rope, moving around him in search of sunlight to recharge the batteries. It is planned that the tests will last for several months (exact timing not reported).
As part of these trials used only one cable, but the design of the robot allows to move from one rope to another, covering large areas that will be useful when examining large areas. According to the developers SlothBot, the robot will eventually be able to work months and even years without human intervention.
Robots moving on the rope, capable of solving other tasks. So, in our country, the developed robotic complex which is designed for condition monitoring of high-voltage cables of the power lines. Oktokopter sets the robot on the ground wire and the one passing along the line, inspecting the route of the imager. Such a scheme allows monitoring of the cables without disconnecting the voltage.
