چکیده

The paper proposes ‘Network-based Humanoid’, that is, a humanoid endowed with its perception capability and intelligence by an external computer system connected with wireless network. The network-based humanoid is composed of a humanoid test-bed, an internal control system and an external computer system. The internal distributed control system is composed of two parts. One is responsible for motion control of the humanoid following commands from the external computer system while the motion control is done by a CAN-based distributed motor controller. The other is for real-time data transmission of image data, voice data, and sensor data for motion control by wireless network to the external computer system. The external computer system, a network-based distributed control system, processes the transmitted data, decides the final action command for the humanoid, and transmits the action command to the internal control system. A network-based humanoid, whose name is ‘MAHRU’, is developed successfully. The humanoid can walk using two legs with the maximum speed of 0.9 Km/h. It is noted that the humanoid can recognize faces, gestures of human beings in real-time, three-dimensional objects, and 100 voice words with the help of the external computer system connected through wireless network. And, the humanoid interacts with human beings via a stereo camera, a microphone, and force/torque sensors.

Audition: the most important sense for humanoid robots?

In this paper, we introduce NAO, the humanoid robot developed by Aldebaran Robotics. For this robot, dedicated to be a companion, the interaction with humans is crucial and the audition appears to be a very important sense while the robotic community has been focusing on vision for a long time. Some of the developments on audio are presented.

Vibration Suppression and Balance Control for Biped Humanoid Walking

In this paper, we present vibration suppression and balance control algorithm for biped humanoid robots in the motion embedded CoM Jacobian. The vibration control is employed during a single supporting phase, which can suppress vibration induced by structure flexibility. Because the previously proposed walking control method in the whole body coordination (WBC) framework is based on the rigid b...

Assistive Humanoid Robot Arm Motion Generation in Dynamic Environment Based on Neural Networks

Assistive humanoid robots operating in everyday life environments have to autonomously navigate and perform several tasks. In this paper we propose a neural network based humanoid robot navigation and arm trajectory generation. The robotic system, which is equipped with a visual sensor, laser range finders, navigates in the environment. The neural controllers generate the robot arm motion in dy...
