Haptics
is a field of science and technology dedicated to tactile sensation and it has
applications fro everything from handheld electronic devices to remotely
operated robotics. Now a days robotics are used to perform surgery. The main
advantages they provide are decreased blood loss,less pain and quicker healing
time. Robotic assistance decreases the fatigue that doctors experience during
surgery. This system developed Robotic
ARM for doctors to perform surgery on the patients even though they are physically
not in the same location. The movement of user's arm along with haptic
technology is used to control the Robotic ARM. Sensors like Mems(Accelerometer)
and Flex sensor is used to control the Robot. Servomotor is used for Robot
motion. A Radio frequency camera is used to transmit the visual signals of
surgery to doctor's PC or TV where a RF Camera receiver is interfaced.
This robot consists of six servos. The robot carries an
embedded system board . Servos can be used for motion. Most servo motors can
rotate about 0 to 180 degrees. Mems and Flex sensors are interfaced to the ADC
channels of microcontroller in transmitter section that can detect the
acceleration,inclination and bend. These sensor values are transmitted to the
microcontroller at receiver section through wireless communication. A zigbee
module is used in this system at transmitter and receiver side for wireless
communication. Servomotor at the receiver sides rotates according to these
sensor values received. Mems and Flex sensors are attached to doctor's
gloves.Both the transmitter and Receiver sections are built with ARM-7 based
microcontroller.
Radio Frequency
cameras are closed-circuit television (CCTV) cameras that transmit a video
and audio signal to a wireless receiver through a radio band. The video images
thus captured can be seen live on TV. It is a low cost surveillance system used
to monitor a larger area.
