In this paper we examine locomotion in the context of self-reconfigurable robots. Self-reconfigurable robots are robots built from many connected modules. A selfreconfigurable robot can change its shape and configuration by changing the way these modules are connected. The focus of this paper is to understand how several locomotion gaits can be represented in such a robot and how the robot can ...

Robot gait training has the potential to increase the effectiveness of walking therapy. Clinical outcomes after robotic training are often not superior to conventional therapy. We evaluated the effectiveness of a robot training compared with a usual gait training physiotherapy during a standardized rehabilitation protocol in inpatient participants with poststroke hemiparesis. This was a randomi...

This paper presents a gait analysis of the equilateral hexagonal model of hexapod robot. Mathematical analysis has been made on mobility, fault-tolerance, and stability. A comparison with the rectangular model of hexapod robot is also given, and it has shown that the hexagonal model shows better turning ability, a higher margin of stability during the fault-tolerant gait, and greater stride len...

This paper gives a treatment of various aspects related to snake locomotion. A mathematical model and a physical implementation of a modular snake robot are presented. A control strategy is also developed, yielding a general expression for different gait patterns. Two forms of locomotion have been simulated with the mathematical model, and experiments with the physical snake robot have been con...

Biped locomotion has proven to be a very hard problem to solve. At current date, there exists no humanoid robot that can move as dynamic and robust as humans do. Even though there has been much research and certainly some interesting progress in biped locomotion, there is certainly no single solution that provides robots with the same capabilities as humans. What seems to be especially lacking ...

This thesis describes the design and implementation of a Walking Algorithm for the humanoid robot. The humanoid is intended to be an autonomous robot, and has a total of 6 degrees of freedom coming from the hip joint, knee joint and ankle joint for each leg. The aim of this thesis project is to develop a walking pattern to control and walk in a stable manner. Exploit methods for developing a na...

Quadruped robot has many advantages over wheeled mobile robots, but it is a discrete system in which joints of each leg has to operate in particular fashion to get the desired locomotion. So, dynamics plays an important role in the operation and control of quadruped robot. Proper conception of the dynamic formulation is must for the complex system like quadruped robot. Here, an attempt is made ...

This paper presents a hybrid structure of re BLOCKINective gait control and adaptive visual servoing [3] by which a vision guided legged robot realizes a re BLOCKINective walk. The re BLOCKINective gait consists of three steps: 1) select a leg to be lifted so as to increase the body stability, 2) move one of other legs to enable the selected leg lifted, and 3) move the selected leg. During thes...

This paper presents a hybrid structure of reflective gait control and adaptive visual servoing [3] by which a vision guided legged robot realizes a reflective walk. The reflective gait consists of three steps: 1) select a leg to be lifted so as to increase the body stability, 2) move one of other legs to enable the selected leg lifted, and 3) move the selected leg. During these steps, adaptive ...

The design and implementation of Fuzzy Policy Gradient Learning (FPGL) method for humanoid robot is proposed in this paper. This paper not only introduces the phases of the humanoid robot walking, but also improves and parameterizes the gait pattern of the robot. FPGL is an integrated machine learning method based on Policy Gradient Reinforcement Learning (PGRL) and fuzzy logic concept in order...
