This paper presents a cooperative control algorithm for a paraplegic patient to walk stably as requested. The algorithm generates stable motions of a lower limb for a paraplegic walk, receiving patient's preference related to his/her movement such as stand-to-sit and sit-to-stand transfers, walking and going up and down stairs. An exoskeletal walking support system assists motions of patient's lower...
As robotic technology plays an increasing role in human lives, ??robot audition??, human-robot communication, is of great interest, and robot audition needs to be robust and adaptable for dynamic environments. This paper addresses sound source localization working in dynamic environments for robots. Previously, noise robustness and dynamic localized sound selection have been enormous issues for practical...
This paper addresses sound source separation and speech recognition for moving sound sources. Real-world applications such as robots should cope with both moving and stationary sound sources. However, most studies assume only stationary sound sources. We introduce two key techniques to cope with moving sources, that is, Adaptive Step-size control (AS) and Optima Controlled Recursive Average (OCRA)...
This paper introduces a vertical ladder climbing of the humanoid robot only by the posture control without any external sensors. The humanoid robot does not have any special structure for fixing the body to the ladder. The robot maintains the body on the ladder by its grippers like human does. As a problem of this locomotion, a free gripper position of the climbing robot is not controllable because...
