ABSTRACT:

In few years ROBOTS are going to rule the universe. Especially in medical field, man power is

reduced by replacing robots. In the existing system, human hand movements is sensed by the

robot through sensors and it imitates the same, but this is made possible by placing the sensor in

the accelerometer and which is to be carried by the person(user’s hand).As the person moves

his/her hand , the accelerometer also moves accordingly which in turn displaces the sensor and

this sensor senses the parameter according to the position of hand and this sensed parameter are

given to the sensors placed in robotic arm which makes the movements of robot arm accordingly.

The drawback faced in this system is, accelerometer should be always carried by the person

and also it cannot be applicable for longer distances.Inorder to overcome these drawbacks, we

go in for this proposed system.In this system, a gesture driven robotic arm is developed, in which

the arm movements and manipulations depends on the gesture of the user. In this system, gesture

is captured by camera and it is processed by LABVIEW software and the parameters are sent to

PC.It is then transmitted (transmitter section) by ZIGBEE transmitter. In the receiver section,

the ZIGBEE receiver holds the received parameters and process with ARM7 microcontroller and

gives those parameters to the robotic arm to make it act accordingly to the gesture. By this

system,it is possible to achieve long distance processing. This system is purposely developed to

apply in medical field for nursing assistance to physicians and in surgeries. And in the receiver

section a wireless camera is placed to monitor the performance of robot arm and also in patient

side(Robot arm side)5 vital parameters (ECG, Respiration rate, Pulse rate,Temperature, Heart

beat) of patient is monitored. This is a preventive measure in case of any imbalance in victim’s

metabolism(temperature,pressure,heart rate), ALARM in transmitter section(physician side) will

be ringing , which inturn brings into notice of physician that patient is in some critical situation,

so that the physician immediately stops the action of robotic arm and he will inform the nearby

doctors to take care of patient. This robotic arm developed is to reduce man power in medical

field, take care of patient in absence of specialist/surgeon and to impart the robotic in

medical areas.
