In the age of an aging society, the prospective role of robots is turning gradually from just working machines to do monotonous work in a factories to partners who support human life. In recent years, a lot of autonomous humanoid robots have been actually realized (Hirai et al. (1998); Kaneko et al. (2008)). These robots can walk on two legs stably by means of the control based on ZMP (Zero Mom...

There are many circumstance limits to human like extreme radioactivity, temperature, chemical toxicity, pressure and so on. But, we need to detect and research region for making our sure safe and state. During long time, human have made a robot that have multi-joint biped robot and mobile robot using wheels. And now, that is developing but it still has some problem that is occurred by condition...

A walking gait is designed for a planar biped with two identical three-link legs, a trunk and two one-link arms. This ninelink biped is controlled via eight torques to obtain a cyclic gait. The scope of this paper is to investigate the effects of arms swing on the reduction of energy consumption during walking of a fully actuated planar biped robot. Kinematics and dynamics of a biped, HYDROID, ...

Abstract—The paper deals with designing and developing a biped robot for research purposes. Robot’s mechanical structure and drives system are described hereunder in details. Moreover the new modified actuator is discussed. An industrial Ethernet-based real-time communication protocol is introduced and the communication ability between the robot-side hardware and PC-side control system is inves...

The aim of this paper is to derive the equations of motion for biped robot during different walking phases using two well-known formulations: Euler-Lagrange (E-L) and Newton-Euler (N-E) equations. The modeling problems of biped robots lie in their varying configurations during locomotion; they could be fully actuated during the single support phase (SSP) and over-actuated during the double supp...

In this paper, we study a simple passive dynamic biped robot with point feet and legs without knee. The mathematical model describing the robot is a switched system, which includes an inverted double pendulum. Robot’s gait and its stability depend on parameters such as the slope of the ramp, mass distribution for the robot, and the length of its legs. The main result of the paper is an asymptot...

Walking on rough terrains still remains a challenge that needs to be addressed for biped robots because the unevenness on the ground can easily disrupt the walking stability. This paper proposes a novel foot system with passively adjustable stiffness for biped robots which is adaptable to small-sized bumps on the ground. The robotic foot is developed by attaching eight pneumatic variable stiffn...
