This letter describes a novel method for non-holonomic robots of convex shape to avoid imminent collisions with moving obstacles. The method's purpose is assist navigation in crowds by correcting steering from the robot's path planner or driver. We evaluate its performance using custom simulator which replicates real crowd movements and corresponding metrics quantify agents' efficiency impact o...

objectives: wheelchairs are the prime mobility aid of persons with spinal cord injuries. manual wheelchair propulsion puts a lot of demand on the cardiopulmonary as well as the skeletal system. the main purpose of the study was to compare the effects of both arm ergometry training and progressive resistance exercise training of upper limbs on resting heart rate and distance covered during wheel...

although construction has been known as a highly complex application field for autonomous robotic systems, recent advances in this field offer great hope for using robotic capabilities to develop automated construction. today, space research agencies seek to build infrastructures without human intervention, and construction companies look to robots with the potential to improve construction qua...

These studies are part of a project aiming to reveal relevant aspects of human-dog interactions, which could serve as a model to design successful human-robot interactions. Presently there are no successfully commercialized assistance robots, however, assistance dogs work efficiently as partners for persons with disabilities. In Study 1, we analyzed the cooperation of 32 assistance dog-owner dy...

There exists the co-operative activity between a human being and rehabilitation robots because the human operates rehabilitation robots in the same environment and has the bene t of rehabilitation robots, such as manipulatory or mobile functions. Intention reading is one of the essential functions of humanfriendly rehabilitation robots in order to promise the comfort and safety for all who need...

In this article, we present an online scalable tele-impedance framework, which enables the individual and collaborative control of multiple different robotic platforms. The framework provides intuitive low-cost interface with visual feedback a SpaceMouse, through operator can define desired task-level trajectories impedance profiles. With simple mouse click, user switch between robots operation...

Background The World Health Organisation recommends that services accompany wheelchair distribution. This study examined the relationship of wheelchair service provision in Kenya and the Philippines and wheelchair-use-related outcomes. Method We surveyed 852 adult basic manual wheelchair users. Participants who had received services and those who had not were sought in equal numbers from whee...

This paper analyses the possibilities of the integration of different technological and knowledge representation techniques for the development of reinforcement frameworks for the remote control of multiple agents such as wheelchair-type robots. Some technological solutions are discussed regarding the recognition of localization of moving objects by using mobile technologies. Large-scale multi-...

OBJECTIVES To determine the patterns of wheelchair use in terms of locations of use, whether wheelchair use in one location was related to wheelchair use in other locations, and factors associated with wheelchair use in different locations. DESIGN Longitudinal cohort study. SETTING Patients prescribed wheelchairs by clinicians at one of two teaching hospitals (one Veterans Affairs hospital ...

The aims of this research are focused on the construction of intellectualized equipments for people with moving disabilities to help them in sustainable integration into environment. The problem is to reveal main components of diagnosis of disabled persons, as well as to develop decision making models which are integrated into the control mechanisms of the special equipments, that are assigned ...
