Aside from swords, knives or lasers, chainsaws are one of the worst possible things incorporated to robots. These are especially dangerous for trees where this pruning robot is able to climb up and lop off multiple limbs that are reachable to it.

A pruning robot

A pruning robot is a great idea. This technology is an important one, too. This is because climbing trees and holding on using a hand, or no hands, while sawing tree branches is extremely dangerous, as injury rates are around ten times as much as someone working at a factory.

This teleoperated robot allows an operator to stand very far while a pruning is done. The robot is also able to do a good job. It climbs up and down the trees with no difficulty, while it is lopping off branches from trees through a spiral motion.

Weighing 13 kilograms, the robot is able to drive vertically up the trees within 6 – 25 centimeters or 2.3 – 9.8 inches in diameter at a speed of 0.25 meters per second. This is done while taking on branches that have a 5 centimeter or less diameter. It is also able to adapt automatically to a range of tree forms. Additionally, it is also energy efficient because it is able to passively support itself while on a tree with the use of its own weight that securely grips the trunk.

A lot of the testing done by the robot is in an ‘experimental forest.’ The trees in this forest seem ideal with them being about as perfect and straight like a sprouting pole for telephones. The continuing research entails making the pruning robot more flexible and robust in terms of various assortments of foliage and trees, and teaching the robot the difference among trees which it should prune and humans it shouldn’t.

This pruning robot called ‘A Pruning Robot with a Power-Saving Chainsaw Drive’ was presented during the 2013 IEEE International Conference on Mechatronics and Automation by Katsuyuki Hirai, Haruhisa Kawasaki and Yasuhiko Ishigure.


Meanwhile, tree services in Australia, such as tree lopping in Perth or tree pruning in Melbourne, which are completed by professionals and experts are currently available as this pruning robot is still subject under further testing and experimentation.
