To achieve New Zealand Wood Council’s export target of $12 billion by 2022 and improve the current reduction of wood harvesting area, the unit value and volume of timber must increase. An effective way to tackle this issue is via tree pruning. However, currently almost all timber pruning work is conducted by lumberjacks. To increase pruning efficiency and improve the automation level in forestry, Mr Pengfei investigated the available tree/pole climbing robots and proposed a novel tree climbing robotic system that could serve as a climbing platform for applications in the forest industry, like tree pruning or inspection. A physical testing model of this proposed robotic system was built and tested on a cylindrical wood rod. His research established a basis for developing wheel-driven tree or pole climbing robots. The design and simulation method, robotic leg mechanism and control methodologies could be easily applied for other wheeled tree/pole climbing robots.
