Barrier Free

Construction of barrier free society is desired especially for elderly and handicapped who need to use wheelchair in daily life. Stair climbing is the hardest barrier for those people. Supply of stair lift method is contribution to provide joy and satisfaction in life of those people. By using our developed crawl-type mechanism on powered wheelchair, they can easily and effectively climb up and down stairs. These system are composed of two subsystems, a few reformed powered wheelchair, drive guide and traction guide attached to stair wall. Presented system is cost effective compared with other existing methods such as elevators, escalators and conventional stair lifts.

Barrier Free

Welfare equipment is being developed for the projected barrier-free society. Stair climbers developed to help wheelchair users climb stairs include multileg, wheeled and crawler types. Stair climbers in practical use, however, may make traveling unstable depending on the stair or be expensive, indicating a need for improvement. This paper proposes a crawler stair climber, named ESCAL-F, that uses a small guide rail with a tooth belt installed at the side edge of stairs and a tooth belt for the crawler in which belts mesh to enable stair climbing. ESCAL-F realizes stable stair climbing with low cost. This paper focuses on design and tilt angle control of ESCAL-F.

Barrier Free

Cooking themselves is very important and difficult for elderly and disabled people in daily life. This paper presents a cooking robot for those people who are confined to wheelchairs. The robot can automatically load ingredients, cook Chinese dishes, take cooked foods out, deliver dishes to the table, self-clean, collect used ingredient box components, and so on. Its structure and interface is designed based on the barrier-free design principles. Elderly and disabled people can only click one button in the friendly Graphic User Interface of a Personal Digital Assistant (PDA) to launch the cooking processes, and several classic Chinese dishes would be placed in front of them one after another within few minutes. Experiments show that the robot can meet their special needs, and the involved aid activities are easy and effective for elderly and disabled people.

Delivering aphasia therapy via telecommunication may provide a means to deliver intensive therapy in a cost-effective way. Teletherapy, remotely-administered (language) treatment, may support the repetitive drill practices that people with chronic aphasia need to perform when learning to compensate for their lasting language difficulties. The use of teletherapy may allow speech and language pathologists (SLPs) to focus in-person sessions more strongly on the generalisation of therapy effects to daily life. This single subject study is an investigation whether a teletherapy application called e-REST meets the criteria of accessibility, user-friendliness, as well as effectiveness. e-REST, the teletherapy version of the Dutch and adapted Reduced Syntax Therapy, teaches chronically aphasic speakers of Dutch who experience difficulties in sentence production to convey their messages in a kind of telegraphic style. The results obtained suggest that it is reasonable to conduct a larger study into the user-friendliness, accessibility, effectiveness, and cost-effectiveness of e-REST.

We study a model of society consisting of agents and a government interacting according to decisions regarding cost-effective punishment of crime. We evaluate different strategies for the government in order to reduce the criminal activity, considering degrees of honesty and a possible cost for monitoring and apprehension. We extend a previous model by introducing a contagion effect for the degrees of honesty, and study properties which may lead to a crime-free society, including a game-theoretic formulation.

This paper mainly focuses on the controlling of home appliances remotely and providing security when the user is away from the place. The system is SMS based and uses wireless technology to revolutionize the standards of living. This system provides ideal solution to the problems faced by home owners in daily life. The system is wireless therefore more adaptable and cost-effective. The HACS system provides security against intrusion as well as automates various home appliances using SMS. The system uses GSM technology thus providing ubiquitous access to the system for security and automated appliance control.

Heavy Loads

This study presents the design of a stair climbing cart to address the problem of lifting the heavy goods up to the stairs conveniently. A detailed design, mechanism and its analysis are presented. Design may be cost effective and affordable compared to human efforts for lifting the objects up to the stairs particularly for heavy loads. It works for a range of steps with step size range of less than 16 cm in height. Our proposed design and its characterisation ensure its functioning in any environmental conditions (such as dusty surface, etc.) and also on tiles/frictionless surface.

In this study, multiple control systems were developed using commonly used wireless communication protocols like Bluetooth, Xbee, and Wi-Fi. Mechanical switch based control systems were initially designed using Xbee and Bluetooth protocols. Further, Android application based control systems were developed using Bluetooth and Wi-Fi protocols. A robotic vehicle was used as an electric-powered wheelchair prototype. Ultrasonic sensors and infrared sensors were integrated with the robotic vehicle for obstacle and pothole detection, respectively. The control systems were tested in an L-shaped corridor for identifying the suitable wireless communication protocol to efficiently guide the robotic vehicle through a scheduled navigational pathway. Both Xbee and Wi-Fi technology based control systems were able to guide the robotic vehicle through the corridor. But the implementation of Xbee communication protocol is economic. However, for shorter distances, Bluetooth technology may be used for cost-effective implementation.

Background. The increase of sanitary costs related to poststroke rehabilitation requires new sustainable and cost-effective strategies for promoting autonomous and dehospitalized motor training. In the Riprendo@Home and Future Home for Future Communities research projects, the promising approach of introducing low-cost technologies that promote home rehabilitation is exploited. In order to provide reliable evaluation of patients, a reference database of healthy people’s performances is required and should consider variability related to healthy people performances.Methods.78 healthy subjects performed several repetitions of daily-life gestures, the reaching movement (RM) and hand-to-mouth (HtMM) movement with both the dominant and nondominant upper limbs. Movements were recorded with a Kinect V2. A synthetic biomechanical protocol based on kinematical, dynamical, and motor control parameters was used to assess motor performance of the healthy people. The investigation was conducted by clustering participants depending on their limb dominancy (right/left), gender (male/female), and age (young/middle/senior) as sources of variability.Results.Results showed that limb dominancy has minor relevance in affecting RM and HtMM; gender has relevance in affecting the HtMM; age has major effect in affecting RM and HtMM.Conclusions.An investigation of healthy subjects’ upper limb performances during daily-life gestures was performed with the Kinect V2 sensor. Findings will be the basis for a database of normative data for neurological patients’ motor evaluation.
