Balancing Controller for a Four-Legged, Bipedal Walking Robot

نویسنده

  • Matt Haberland
چکیده

A controller is developed to balance a two-dimensional walking robot. The equations of motion for the robot, modelled as a double pendulum with pivots at the hip and contact foot, are derived, linearized, and arranged in statespace form. A Linear Quadratic Regulator is developed for the linearized model; its performance simulated using both the linearized and the complete, nonlinear dynamics. The regulator fails to stabilize a physical four-legged biped due to measurement difficulties, and recommendations for measurement and controller improvement are proposed in response.

Reconstructing human push recovery reactions using a three dimensional under-actuated bipedal robot

This paper presents the ability of hybrid zero dynamics (HZD) feedback control method to reproduce human like movements for walking push recovery of an under-actuated 3D biped model. The balance recovery controller is implemented on a three-dimensional under-actuated bipedal model subjected to a push disturbance. The biped robot model is considered as a hybrid system with eight degrees of freed...

Design and Trajectory Planning of Bipedal Walking Robot with Minimum Sufficient Actuation System

This paper presents a new type of mechanism and trajectory planning strategy for bipedal walking robot. The newly designed mechanism is able to improve the performance of bipedal walking robot in terms of energy efficiency and weight reduction by utilizing minimum number of actuators. The usage of parallelogram mechanism eliminates the needs of having an extra actuator at the knee joint. This m...

Spring-mass Walking with Atrias in 3d: Robust Gait Control Spanning Zero to 4.3 Kph on a Heavily Underactuated Bipedal Robot

We present a reduced-order approach for robust, dynamic, and efficient bipedal locomotion control, culminating in 3D balancing and walking with ATRIAS, a heavily underactuated legged robot. These results are a development toward solving a number of enduring challenges in bipedal locomotion: achieving robust 3D gaits at various speeds and transitioning between them, all while minimally draining ...

Position Control of a Four-Legged Walking Robot with Neural Network

In this paper, the use of a proposed recurrent neural network control system to control a four-legged walking robot is investigated. The control system consists of a neural controller, standard PD controller and the walking robot. The robot is a planar four-legged walking robot. The proposed Neural Network (NN) is employed as an inverse controller of the robot. The NN has three layers, which ar...

Development of Multi-legged Passive Dynamic Walking Robot

This research realizes and analyze Multi-legged Passive Dynamic Walking(PDW). Although various PDW studies have been conducted based on its interesting features, most of them dealt with bipedal robots. There are many kinds of multi-legged creatures, not only quadrupedal animals but also creatures with more than six legs. In this paper, we focus on a “Multi-legged PDW,” which is a PDW with more ...
