چکیده

This paper addresses the problem of modelling and control of a biped robot by combining Cartesian-based position and force control algorithms. The complete walking cycle is divided in two phases: i) single support in which it is studied the trajectory controllability based on simple motion goals and ii) exchange of support in which the forward leg should absorb the impact and then gradually accept the robot’s weight. The contact of the foot with the constrained surface is modelled through linear spring-damper systems. The control algorithms are simulated and their effectiveness and robustness are discussed.

An Optimized Neuro-Fuzzy Controller Design for Bipedal Locomotion

al. [3] in the case of a humanoid robot based on hybrid fuzzy control methods. This paper proposes a bipedal locomotion controller using an optimized Neuro-Fuzzy inference structure. In which, it is based on an adaptive neuro-fuzzy inference identifier (ANFII) for modeling the inverse dynamics of the biped robot. The proposed learning scheme is based on the zero moment point (ZMP); while the mo...

Survey of Semi-Passive Locomotion Methodologies for Humanoid Robots

Wheel-based locomotion is the most commonly used by mobile robots, due to its simplicity and robustness. However, when facing uneven terrain, such as steps or rocky terrain, its mobility is greatly reduced. Biped robots, in contrast, have a greater adaptation potential to these challenges due to the suitability of its structure. In spite of this, the traditional biped locomotion methods used by...

Optimized Joint Trajectory Model with Customized Genetic Algorithm for Biped Robot Walk

Biped robot locomotion is one of the active research areas in robotics. In this area, real-time stable walking with proper speed is one of the main challenges that needs to be overcome. Central Pattern Generators (CPG) as one of the biological gait generation models, can produce complex nonlinear oscillation as a pattern for walking. In this paper, we propose a model for a biped robot joint tra...

Humanoid Robot Walking Trajectory Generation and Hybrid Control

Past three decades witnessed a growing interest in biped walking robots because of their advantageous use in the human environment. However, their control is challenging because of their many DOFs and nonlinearities in their dynamics. Various trajectory generation and walking control approaches ranging from open loop walking to systems with many sensors and feedback loops have been reported in ...

Robust Biped Walking with Active Interaction Control between Foot and Ground

This paper describes a biped walking control system based on the reactive force interaction control at the foothold. 1) robust control of reactive force/torque interaction at the foothold based on Cartesian space motion controller. 2) the posture control considering the physical constraints of the reactive force/torque at the foothold by quadratic programming. The proposed approach realizes the...
