WIRELESS SIGNALS AUTOMATED PHYSIOLOGICAL DATA ACQUISITION FROM WIRELESS BODY SENSOR IS A NOVEL WAY TO INEXPENSIVE HEALTH CARE SOLUTION. A SOFTWARE CAN ALSO BE PROGRAMMED TO USE THE DATA TO MANOEUVRE A ROBOT BE IT A SINGLE ARM. WITH ADVANCES IN EMBEDDED MICROCONTROLLERS, WIRELESS NETWORK TECHNOLOGIES AND LIGHT WEARABLE SENSOR UNITS LIKE ELECTROCARDIOGRAM (ECG), ELECTROMYOGRAM (EMG), ELECTROENCEPHALOGRAM (EEG), THERE HAS BEEN A GROWING INTEREST IN ITS MEDICAL APPLICATIONS.
WHAT WE PLAN TO MAKE I PLAN ON MAKING NUMEROUS SMALL MICRO-BOTS. SHOULD AKHILESH MAKE SUCH A ROBOT WHICH IS VERY SMALL (SIZE OF A BEE), WHICH IS CAPABLE OF TRANSMITTING AND RECEIVING WIRELESS SIGNALS AND SHOULD HE MAKE IT IN SUCH A WAY THAT A SINGLE MICROBOT RECOGNISES WHERE EXACTLY IN 3D SPACE ON THE EARTH IT SHOULD BE LOCATED (GPS, ACCELEROMETER, LIGHT SENSORS, MEM GYROSCOPES ETC SHOULD DO THE TRICK) AND IN WHAT ORIENTATION IT SHOULD PLACE ITSELF, THE IDEA OF MICRO-BOTS IS QUITE FEASIBLE. THE MICRO-BOT SHOULD BE ABLE TO MOVE ON THE SURFACE OF ANOTHER MICRO-BOT ( I HOPE AKHILESH I AM NOT ASKING TOO MUCH... :-P). WHAT I PLAN IS TO CIRCULATE NANOBOTS IN THE CIRCULATORY SYSTEM WHICH RECOGNIZES THE BRAIN PATTERN AND SEND IT TO A TRANSMITTER VIA MICRO-CONTROLLER, WIRELESSLY. THUS, FOR EXAMPLE, A PERSON IS THINKING OF MAKING A CHAIR; THE NANOBOTS RECOGNIZES THE BRAIN WAVES AND TRANSMIT IT WIRELESSLY VIA A TRANSMITTER TO A SUPERCOMPUTER WHICH RECOGNIZES THE PATTERN. A SOFTWARE HAS TO BE DEVELOPED AND PROGRAMMED WHICH CAN RECOGNIZE THE BRAIN WAVES PATTERN AND AGAIN A TRANSMITTER RELAYS THE SIGNALS TO THE MICRO-BOTS DIRECTING IT TO MAKE A CHAIR IN THE 3D SPACE. STARTING FROM A REFERENCE POINT, ONE BY ONE, ALL THE MICROBOTS NAVIGATES AND REARRANGES THEMSELVES BY MOVING ON ONE ANOTHER TO ULTIMATELY FORM A 3D CHAIR. THUS IF WE THINK OF MAKING A TABLE, MICRO- BOTS MAKE A TABLE BY A SINGLE MICRO-BOT BECOMING A SMALL PART OF THE TABLE. AS THE MICRO-BOTS ARE VERY SMALL, IF WE HAVE MANY IN NUMBER, WE CAN MAKE ANY STRUCTURE WE WANT TO MAKE. ITS LIKE A MASON CONSTRUCTING A BEAUTIFUL BUILDING WITH BRICKS, ONLY A MILLION FOLD FASTER AS THIS TECHNOLOGY USES A SUPERCOMPUTER.
APPLICATION OF THE TECHNOLOGY 1) THE WIRELESS DATA ACQUIRED FROM THE BODY SENSOR CAN BE USED TO MOVE A ROBOTIC ARM. THUS IT CAN BE USED FOR A PHYSICALLY CHALLENGED PERSON SO THAT HE CAN DO WORK WITH THE ROBOTIC ARM. 2) THE WIRELESS DATA ACQUIRED CAN BE FROM SENSORS WHICH MONITOR HEART, SKIN, NERVES ETC. THUS IT CAN BE USED TO MONITOR A PERSON'S HEALTH AND BEING WIRELESS IT CAN BE TRANSFERRED VIA BLUETOOTH TO AN ANDROID DEVICE LIKE CELLPHONE SO THAT THE PERSON CAN MONITOR HIS HEALTH WITH THE COMFORT OF SITTING AT HOME AND RELAYS THE DATA TO THE HOSPITAL DOCTORS. 3) IF WE CAN MAKE MANY SMALL FLEXIBLE ROBOTS AND PROGRAM THEM IN SUCH A WAY THAT WITH ALL THE ROBOTS CONNECTED WITH EACH OTHER WE CAN MAKE ANY STRUCTURE WE CAN THINK OF THOUGH IT WILL REQUIRE A HIGH SPEED COMPUTER LIKE A SUPERCOMPUTER AS IT HAS TO RELAY AND PROCESS A HUGE AMOUNT OF DATA. WE ALSO HAVE TO DEVELOP A DEVICE WHICH CAN RECOGNIZE WHAT WE THINK AND RECOGNIZE IT. ITS APPLICATIONS ARE NUMEROUS LIKE IN CIVIL ENGINEERING WHERE WHAT WE THINK CAN ACTUALLY BE MADE BY ALL THE ROBOTS TOGETHER. IT CAN BE USED IN TRANSPORTATION LIKE SHOWN IN THE ANIMATED MOVIE POSTED BY ME EARLIER. 4) IT CAN BE USED IN SPACE RESEARCH WHERE THE ROBOTS ARE TRANSPORTED TO MOON OR MARS AND IF HOW THE HUMAN MOVE CAN MANOEUVRE THE ROBOT, IT CAN TRAVERSE MUCH MORE DIFFICULT TERRAIN THAN IT CAN WITH MERE CONTROL USING FPV (FIRST PERSON VIEW). 5) WE CAN MAKE A DEVICE THAT CAN HELP PHYSICALLY CHALLENGED LIKE STEPHEN HAWKING TO SPEAK. AS WE KNOW THOUGH HE CANNOT SPEAK NOR MOVE MOST OF HIS MUSCLES BUT CHEEK MUSCLES. THEREFORE AN ACCELEROMETER CAN BE ATTACHED TO MEASURE THE ACCELERATION OF THE MUSCLE WHICH IS RELAYED WIRELESSLY TO A COMPUTER WHICH USES THE ACQUIRED DATA TO SELECT A LETTER FROM THE ARRAY OF ALPHABETS. THUS IT ALLOWS HIM TO FORM A WORD, SENTENCE, PARAGRAPH. HE HAS EVEN WRITTEN A WHOLE BOOK WITH THIS METHOD. 6) WIRELESS TECHNOLOGY HAS MANY APPLICATIONS LIKE MOBILE, TV SATELLITES, RC PLANES ETC. BUT WE ARE LIMITING OURSELVES TO ITS APPLICATION OF RELAYING DATA FROM WEARABLE BODY SENSORS.
USE OF BLUETOOTH TECHNOLOGY FOR COMMUNICATION BETWEEN WIRELESS SENSOR AND COMPUTER Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.wirelessUHFradio wavesISM bandpersonal area networksEricssonRS-232
Our design is targeted for indoor use such as in a house and a nursing home environment. Therefore, a short-distance wireless communication system is appropriate. Two types of wireless communication standards are suitable for this application: IEEE (Bluetooth) [6] for medium rate wireless personal area networks (WPAN) and IEEE (ZigBee) [7] for low rate WPANs, both operating in the 2.4 GHz unlicensed industrial, scientific, and medical (ISM) frequency band IEEE specifies physical layer and medium access control for WPANs which focus on low- cost, low-speed ubiquitous communication between devices. It is designed for systems that need a battery life as long as several months to several years but do not require a data transfer rate as high as those enabled by Bluetooth. The compliant devices have a transmission range between 10 and 75 meters and a data transfer rate of 250 kbps (if operating at 2.4 GHz frequency band) supports a basic master-slave configuration suited to static star networks of many infrequently used devices that talk via small data packets. Compared with Bluetooth, is more power-efficient because of its small packet size, reduced transceiver duty cycle, reduced complexity, and strict power management mechanisms such as power-down and sleep modes. Both IEEE and IEEE have been used as the wireless communication protocol in different wearable sensing platforms for measuring and recognize human activities, e.g., [8][9]. After comparing the two choices of applicable wireless standards, it is clear that IEEE is the better choice for our proposed design that requires short range wireless communication between low-cost, low-power, and battery-operated devices for monitoring purposes.
