Description

Multifunctional medical monitoring intelligent wheel chair and wheelchair control method
Technical field
The present invention relates to the service robot technical field, refer to particularly a kind of multifunctional medical monitoring intelligent wheel chair and wheelchair control method.
Technical background
In recent years, because old people's ratio increases, its quality of life and health status need to obtain the caring attention of society, and the life of the isolation sufferer of hospital and rehabilitation link need to expend a large amount of manpower and materials.
Large quantity research has been done to the service class robot by the country such as America and Europe and Japan and Korea S, and has produced many finished products, and some finished product is the marketization even.And at present in China, due to start late for service class robot field's research and development, target is disperseed, inorganizable, insufficient investment, causes product in this regard less.
The service robot typical products has the Robot Helps Me To Avoid Danger nurse Care-O-Bot3 of Germany, is mainly used in to replace some dangerous, poisonous, harmful work positions, and the high 1.5m of this robot, whole body spreads all over sensor, can move freely; The touch screen of front has acoustic control or gesture control ability, can also understand voice command and understand gesture command.The remote monitoring machine people ConnectR of U.S. iRobot company exploitation.The user can pass through this supervisory control of robot domestic environment, can with friend's video interactive, can monitor house pet.ConnectR is by high-quality video, and voice messaging provides virtual visit.The user can control by the PC that can surf the Net this robot, and by password is set, robot can only allow by people's control and the virtual visit of authentication.The novel wheel chair robot of Japan is named as " RT-Mover ", and middle island professor shows how it easily climbs up and highly reaches the step of 25 centimetres, and its wheel can also rotating 360 degrees.
According to current market survey, most of robot has following shortcoming: 1, function ratio is more single, can only complete the action of mechanization repeatedly, Care-O-Bot3 above-mentioned for example, outer likeness in form vacuum cleaner, people can only control it by the touch screen of its front, sometimes gesture misinterpretation, can carry out wrong operation, can only complete some simple work, and can not help handicapped personage to move.And the ConnectR robot with a high-definition camera and wifi network, can carry out video, speech exchange due to it, but only rests in interchange, can't extract articles for daily use for the user.And above two class robots do not possess wheelchair class device, thus can not be manned, can't satisfy some handicapped personages and old user's the requirement such as trip, shopping.Wheel chair robot and for example although climbing capacity is strong, can only provide manned trip this function.2, above robot does not have interface and the mode of operation of some hommizations, generally only have some buttons and simple touch screen, this just must the specialty operation, could allow the relatively accurate requirement of completing appointment of robot, can only be operated by the professional person, thereby caused the whole day service of " one to one " formula, wasted a large amount of manpower and materials, also brought huge economic pressures to consumer.
The shortcomings such as in sum, there is function singleness in above robot, and operability is poor.
