Controlling a remotely located Robot using Hand Gestures in real time: A DSP implementation

摘要

Telepresence is a necessity for present time as we can't reach everywhere andalso it is useful in saving human life at dangerous places. A robot, whichcould be controlled from a distant location, can solve these problems. Thiscould be via communication waves or networking methods. Also controlling shouldbe in real time and smooth so that it can actuate on every minor signal in aneffective way. This paper discusses a method to control a robot over thenetwork from a distant location. The robot was controlled by hand gestureswhich were captured by the live camera. A DSP board TMS320DM642EVM was used toimplement image pre-processing and fastening the whole system. PCA was used forgesture classification and robot actuation was done according to predefinedprocedures. Classification information was sent over the network in theexperiment. This method is robust and could be used to control any kind ofrobot over distance.
