This book was released on 2017-10-19 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2017 in the subject Engineering - Robotics, language: English, abstract: Researchers dream of developing autonomous humanoid robots which behave/walk like a human being. Biped robots, although complex, have the greatest potential for use in human-centered environments such as the home or office. Studying biped robots is also important for understanding human locomotion and improving control strategies for prosthetic and orthotic limbs. Control systems of humans walking in cluttered environments are complex, however, and may involve multiple local controllers and commands from the cerebellum. Although biped robots have been of interest over the last four decades, no unified stability/balance criterion adopted for stabilization of miscellaneous walking/running modes of biped robots has so far been available. The literature is scattered and it is difficult to construct a unified background for the balance strategies of biped motion. The zero-moment point (ZMP) criterion, however, is a conservative indicator of stabilized motion for a class of biped robots. Therefore, we offer a systematic presentation of multi-level balance controllers for stabilization and balance recovery of ZMP-based humanoid robots.

Download or read book Whole Body Control for Multi Contact Balancing of Humanoid Robots written by Bernd Henze and published by Springer Nature. This book was released on 2021-11-03 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims at providing algorithms for balance control of legged, torque-controlled humanoid robots. A humanoid robot normally uses the feet for locomotion. This paradigm is extended by addressing the challenge of multi-contact balancing, which allows a humanoid robot to exploit an arbitrary number of contacts for support. Using multiple contacts increases the size of the support polygon, which in turn leads to an increased robustness of the stance and to an increased kinematic workspace of the robot. Both are important features for facilitating a transition of humanoid robots from research laboratories to real-world applications, where they are confronted with multiple challenging scenarios, such as climbing stairs and ladders, traversing debris, handling heavy loads, or working in confined spaces. The distribution of forces and torques among the multiple contacts is a challenging aspect of the problem, which arises from the closed kinematic chain given by the robot and its environment.
Download or read book Bipedal Robots written by Christine Chevallereau and published by John Wiley & Sons. This book was released on 2013-03-01 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents various techniques to carry out the gait modeling, the gait patterns synthesis, and the control of biped robots. Some general information on the human walking, a presentation of the current experimental biped robots, and the application of walking bipeds are given. The modeling is based on the decomposition on a walking step into different sub-phases depending on the way each foot stands into contact on the ground. The robot design is dealt with according to the mass repartition and the choice of the actuators. Different ways to generate walking patterns are considered, such as passive walking and gait synthesis performed using optimization technique. Control based on the robot modeling, neural network methods, or intuitive approaches are presented. The unilaterality of contact is dealt with using on-line adaptation of the desired motion.
Download or read book Dynamic Stabilisation of the Biped Lucy Powered by Actuators with Controllable Stiffness written by Bram Vanderborght and published by Springer Science & Business Media. This book was released on 2010-10-04 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports on the developments of the bipedal walking robot Lucy. Special about it is that the biped is not actuated with the classical electrical drives but with pleated pneumatic artificial muscles. In an antagonistic setup of such muscles both the torque and the compliance are controllable. From human walking there is evidence that joint compliance plays an important role in energy efficient walking and running. Moreover pneumatic artificial muscles have a high power to weight ratio and can be coupled directly without complex gearing mechanism, which can be beneficial towards legged mechanisms. Additionally, they have the capability of absorbing impact shocks and store and release motion energy. This book gives a complete description of Lucy: the hardware, the electronics and the software. A hybrid simulation program, combining the robot dynamics and muscle/valve thermodynamics, has been written to evaluate control strategies before implementing them in the real biped.

Download or read book Balance Control of a Five DOF Robot Leg written by Joshua L. Abela and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A biped robot, also known as a humanoid robot, is built to resemble the shape and perform the actions of the human body. While functioning, a biped robot interacts with surrounding human environments. Currently, various robots have been developed to resemble many parts of the human body, such as the head or torso. This material focuses on the development of one robotic leg. Research in humanoid robots will expand knowledge of the human body, while producing greater understanding of the precise motions of the human gait. The eld of research in biped robots is very interesting, and creating something similar to that of the human body is a challenging task. The concept of walking robots is motivating and interesting enough, to perform research in the eld. There are two di erent robot designs, one for the simulation based purposes and the other for real-time data collection. The simulations will be used to help understand the formulas that were developed and researched, in order to control a biped robot. These methods include the Denavit-Hartenberg parameters, Newton-Euler Recursion, Trajectory Generation, Center of Mass and Zero Moment Point. The second robot design, which provides real-time data collection, will be done on a single ve degree of freedom legged robot. This robot leg is equipped with a motor and encoder at each joint that will be used to move and track its position. The foot has four force moment sensors on the bottom of the foot that will be used to help balance the robot leg in the upright position. Since its only a single legged robot, balance is its primary objective.
Download or read book Modeling and Designing Bipedal Walking Robot written by Ashish Thakur and published by Independently Published. This book was released on 2018-10-07 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: A humanoid robot is a robot with its body shape built to resemble the human body. The design may be for functional purposes, such as interacting with human tools and environments, for experimental purposes, such as the study of al locomotion or for other purposes. In general, humanoid robots have a torso, a head, two arms, and two legs, though some forms of humanoid robots may model only part of the body, for example, from the waist up. Some humanoid robot also have heads designed to replicate human facial features such as eyes and mouths. Androids are humanoid robots built to aesthetically resemble humans. It is easier for bipedal robots to exist in a human oriented environment than for other types of robots. Furthermore, dynamic walking is more efficient than static walking. For a biped robot achieve dynamic balance while walking, a dynamic gait must be developed. Two different approaches to gait generation are presented

Available in PDF, EPUB and Kindle. Book excerpt: ThesearetheproceedingsoftheRoboCup2004Symposium,heldattheInstituto Superior T ́ ecnico, in Lisbon, Portugal in conjunction with the RoboCup c- petition. The papers presented here document the many innovations in robotics that result from RoboCup. A problem in any branch of science or engineering is how to devise tests that can provide objective comparisons between alt- native methods. In recent years, competitive engineering challenges have been established to motivate researchers to tackle di?cult problems while providing a framework for the comparison of results. RoboCup was one of the ?rst such competitions and has been a model for the organization of challenges foll- ing sound scienti?c principles. In addition to the competition, the associated symposium provides a forum for researchers to present refereed papers. But, for RoboCup, the symposium has the greater goal of encouraging the exchange of ideas between teams so that the competition, as a whole, progresses from year to year and strengthens its contribution to robotics. One hundred and eighteen papers were submitted to the Symposium. Each paper was reviewed by at least two international referees; 30 papers were - cepted for presentation at the Symposium as full papers and a further 38 were accepted for poster presentation. The quality of the Symposium could not be maintained without the support of the authors and the generous assistance of the referees.
Download or read book Control Framework for Dynamic Walking of a Bipedal Robot written by Kishan Kumar Bhongale Prabhakar Prasad and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite significant progress in recent years, the capabilities of today's Humanoid robots still lack behind the walking abilities of humans in terms of competence, robustness, flexibility, and speed. Furthermore, unknown environmental conditions and related constraints imposed on the robot significantly increase the complexity of locomotion control and decision making for such systems, easily making planning-based approaches intractable. Part of the reason for this is that the control of a humanoid encompasses observation, processing the observed data, and decision making in terms of locomotion gait and body pose parameters. This key information derived from observations and internal robot information finally allows calculating the appropriate signals to be fed to the actuators, which in turn move and adjust the mechanical joints with respect to the environment. The complexity of biped walking is also driven by the kinematic structure of the robot. If the robot has a large number of degrees of freedom, the parameters that can be used to affect the robustness of the robot increase along with the number of controls. This, in turn, can lead to a significant increase in computation cost in monolithic control approaches that compute gait and control for the entire kinematic mechanism. As a contribution towards the objective of developing useful walking machines, the work presented in this thesis takes a modular approach to locomotion control where the overall control task is decomposed into elements with individual subtask responsibilities. The goal here is to break the overall complexity into manageable parts by relying on the robustness and reactivity of the other modules. This thesis presents a basic overview of this approach and then focuses on the development of the parts of this approach centered around flexible gait generation. In this part it focuses on modules that address very specific problems of walking such as permitting dynamically changing step lengths, stepping frequencies, height of the body, and stance stability during the walk cycle, in order to adjust itself to the environment, prevent it from falling down, and address foothold and pace parameters provided by higher-level, environment-dependent modules. This thesis proposes a control framework that stabilizes a humanoid robot while these characteristics of the walk are changed. In the modules developed to achieve this, methods such as position control flexible walking pattern generation using parametric trajectories, and zero-moment control for reactive stabilization are used to generate a dynamically walk. The resulting controller is demonstrated using a simulated humanoid model taking into account the natural dynamics, torque limits and the model of the walking surface.
