Speaking aid for dumb - a simple project

ABSTRACT

      Speaking aid for dumb convert the gestures used by the dumb persons to sound. When a dumb person communicates using gestures, corresponding sounds will be heard through speaker. This will help the dumb people communicate with normal people who do not understand their gestures. LED-LDR networks are used for sensing the gestures. A flexible tube is placed between LED and LDR for passing the light. The LED-LDR network is placed on a glove worn by the dumb person. According to the finger bending, LDR resistance varies. The output of the sensor is converted to voltage and interfaced to   a LABVIEW through Arduino. The corresponding prerecorded sounds are played through loud speakers. This work produced sound for the gestures for the numbers 0 to 9 for which it was designed.

AUTOMATIC PICK AND PLACE ROBOT

AUTOMATIC PICK AND PLACE ROBOT
{implemented based on below paper}

With the help of machine vision we identify the object and remove the noise in it. Visual servoing is used to control the trajectory of the robot toward the object in the image. After that we want to pick the object and return to the starting position for placing it.  We use Arduino, H bridge and motors for controlling the robot. This is the block diagram for automatic pick and place robot using camera. This contains mainly eight blocks as shown in Fig
