A mobile platform-based rehabilitation robotic system with a lower-extremity exoskeleton was developed for people with disabilities to allow them to perform therapeutic exercises and to support daily living activities. The system consists of a weight support module, a locomotion module, and an exoskeleton module for lower extremities. We collected the needs and feedback of users and clinical experts...
A wearable elbow joint with three passive joints is proposed in this paper. The joint has an advantage of easy attachment to a human arm, without thorough adjustment when attached. This paper describes kinematics, statics and a prototype of the proposed joint, and then reports results of preliminary evaluation.
Walking is a popular recreation activity. In addition, it is a mild and healthy exercise for the elderly. However, people suffering from physical and / or cognitive disorders have a difficulty in going out and walking in real environments. Therefore we have proposed a virtual walking system with a haptic device on feet. This system consists of visual, sound, and haptic devices to present various kinds...
The purpose of this research is to achieve a user friendly interface for teleoperation in versatile purpose. However, it is difficult to teleoperate a robot for general persons. In this paper, we propose a new interface to improve usability with a touch based Multi-Modal interface for teleoperation for non-expert. The operator is able to operate a robot without spatial restriction since the proposed...
This paper proposes the laser extraction system by adjusting camera parameters. This system is based on presentation tool with laser pointer, and it detects the laser spot overlapped with projection image by CCD/CMOS camera. In this research, we confirmed the method of extracting laser spot from projection image by adjusting camera parameters. We determined essential parameters and optimal threshold...
