摘      要：A novel method to calculate the bended finger s angle has presented here which could be used to control the electro-mechanical robotic hand. It is assumed that the robotic hand has the human hand like joints and same number of degree of freedom as human hand. In many applications, equipment like human hand is needed to do the same kind of operation like human do. These days it is easy to make the electro-mechanical robotic hand which has five fingers and same joints but it is not easily controllable as the human hand for accurate job. In our method the hand gesture will be interpreted for controlling the robotichand. The angles for all the fingers will be calculated and that could be further passed to the robotic hand for controlling its finger. User would perform gesture according to the action as he wants to be done by robotic hand. Here finger positions are detected using geometric analysis of hand in the extracted image, while region of interest cropping from the image make the algorithm faster. © 2012 ACADEMY PUBLISHER.
