Climbing robot is a challenging research topic that has gained much attention from researchers. Most of the robots reported in the literature are designed to climb on manmade structures, but seldom robots are designed for climbing natural environment such as trees. Trees and manmade structures are very different in nature. It brings different aspects of technical challenges to the robot design. In this book, you can find a collection of the cutting edge technologies in the field of tree-climbing robot and the ways that animals climb. It provides a valuable reference for robot designers to select appropriate climbing methods in designing tree-climbing robots for specific purposes. Based on the study, a novel bio-inspired tree-climbing robot with several breakthrough performances has been developed and presents in this book. It is capable of performing various actions that is impossible in the state-of-the-art tree-climbing robots, such as moving between trunk and branches. This book also proposes several approaches in autonomous tree-climbing, including the sensing methodology, cognition of the environment, path planning and motion planning on both known and unknown environment.

In recent years, researchers have developed a variety of bio-inspired robots that can climb surfaces ranging from brick and stucco to smooth glass. Instrumental in this development has been the utilization of specialized compliant foot structures. By attaching micro spines and directional dry adhesives to legs with hierarchical compliance levels, climbing on windows and walls has been made possible. In parallel with these developments in attachment mechanisms, recent work has been done to improve the speed and efficiency with which robots climb. Comparative studies of animals running up vertical surfaces have led to the development of reduced-order dynamic models of climbing. These models, or templates, give insight into how animals generate self-stabilizing force patterns, and have led to the development of a new class of dynamic climbing robots. The first and fastest of these climbers, DynoClimber, can climb at speeds up to 66 cm/s or 1.5 body lengths per second up a vertical, prepared surface. Although fast, these climbers are not yet able to scale real world surfaces such as buildings or trees. This paper describes initial work in developing a dynamic vertical climbing robot for climbing on bark.

Abstract: This work addresses the problem of generating a 3D mesh grid model of a tree by a climbing robot for tree inspection. In order to generate a consistent model of the tree while climbing, the robot needs to be able to track its location while generating the model. Hence we explored this problem as a subset of Simultaneous Localization and Mapping problem. The monocular camera based Visual Simultaneous Localization and Mapping(VSLAM) algorithm was adopted to map the features on the tree. Multi-scale grid based FAST feature detector combined with Lucas Kande Optical flow was used to extract features from the tree. Inverse depth representation of feature was selected to seamlessly handle newly initialized features. The camera and the feature states along with their co-variances are managed in an Extended Kalman filter. In our VSLAM implementation we have attempted to track a large number of features. From the sparse spatial distribution of features we get using Extended Kalman filter we attempt to generate a 3D mesh grid model with the help of an unordered triangle fitting algorithm. We explored the implementation in C++ using Eigen, OpenCV and Point Cloud Library. A multi-threaded software design of the VSLAM algorithm was implemented. The algorithm was evaluated with image sets from trees susceptible to Asian Long Horn Beetle.

Design And Development Of Self Balancing Climbing Machine For Oil Palm Harvesting written by Hamed Shokripour and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2010 with categories.

Oil palm is a major plantation crop in Malaysia. The country successfully developed the oil palm plantation industry during the past three decades and it is now one of the largest palm oil producers in the world. However, due to the lack of specific machinery for harvesting oil palm fruits, the harvesting operation is still done using the traditional method of a sharp knife that is attached to the head of a long pole. This traditional method of harvesting requires strong workers with special experience and skills. In the face of a decreasing number of these skilled workers, their salaries have increased, which has added to the cost of harvesting. Furthermore, using the traditional method, workers cannot harvest fruits from trees which are too tall. The project was to design, fabricate and test a new self-balancing and remote-controlled four wheeled climbing robot for oil palm trees and a special cutting system for cleaning the fronds. A control system was designed and fabricated for the climbing robot to keep the robot's balance during the climbing process by individually controlling the speed of each wheel. A dual axis tilt sensor was used to simultaneously measure the angle of tilt for both X and Y axes. In addition, a carrier machine was designed and fabricated to bear different equipment - such as the cutting system, digital camera and sprayer - and carry these around the tree trunk to enable them to undertake different processes. The operator controls the climbing robot and carrier machine via a specific remote control. The speeds of the DC motors are controlled by a Pulse-width modulation (PWM). A specific program was written with Bascome software in Basic language for an ATmega64 microcontroller as the Arithmetic and Logic Unit of the robot. All parts of the robot were successfully tested in laboratory and field conditions. The time and motion study was carried out on several trees. The average time required to place the robot around the tree, then have it climb up, cut a frond, and descend, was about eight (8) minutes for each tree. The maximum angle of tilt around X and Y axes were eight (8) and six (6) degrees respectively. The robot successfully negotiated the irregularities of the tree trunk's surface and automatically set its size relative to changes in the diameter of the tree trunk. The carrier machine carried the cutting machine and moved smoothly around the tree trunk. Both the climbing robot and carrier machine responded successfully to the commands sent from the remote control by the operator. Key words: Climbing Robot, Cutting System, Oil Palm, Self Balancing, PWM.
